The portable crusher plant is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals. The portable crusher plant can grind various ores and other materials either wet or dry. There are two kinds of portable crusher plant, grate type and over fall type due to different ways of discharging material. There are many types of grinding media suitable for use in a portable crusher plant, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition. Portable crusher plants are used extensively in the mechanical alloying process in which they are not only used for grinding but for cold welding as well, with the purpose of producing alloys from powders. Portable crusher plants are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality portable crusher plants are potentially expensive and can grind mixture particles to as small as 5 nm, enormously increasing surface area and reaction rates. The grinding works on the principle of critical speed. The critical speed can be understood as that speed after which the steel balls which are responsible for the grinding of particles start rotating along the direction of the cylindrical device; thus causing no further grinding.

With the large-scale development trend of gold ore crusher, the overall transformation of gold ore crusher is imminent. Therefore, the change of bearing becomes a ladder of progress for gold ore crusher. gold ore crusher is one of the main mining equipment of SBM Machinery, and the research on the technology of gold ore crusher is an important engineering projects. In the face of the hot topic, how to produce the best bearing to get the maximum benefit has become the main problem for gold ore crusher manufacturers. Therefore, the realization of energy saving and high efficiency, our engineers personnel proposed new technology ideas from many aspects. Advanced technology is an important factor in the development of enterprises, the experts in our company believe that if enterprises want to stand out in mining industry, and we must take the market demand and its own development strategy as the guidance, adjust the working mode, look for new opportunities and improve the technology content of its own. Due to the large-scale development of gold ore crusher, as a key component, the working stability of bearing will directly affect the normal operation of gold ore crusher. From the traditional development of small ball, the diameter of the cylinder can achieve that of above 7 meters large gold ore crusher, the main bearings mainly use general sliding bearing, the rolling bearing, the dynamic pressure bearing, the dynamic and static pressure bearing and the static pressure bearing. At present, the hydrostatic bearing has characteristics of high reliability, long service life, low energy consumption, large capacity, etc. It is widely used in large-scale energy saving gold ore crusher. Whether it is stationary or rotating gold ore crusher, it is to rely on between the bearing under the action of high pressure oil outside and hollow shaft forms a thick layer of oil film, so as to achieve full liquid lubrication. The relationship between the lubrication state of hydrostatic bearing and oil film pressure and the hollow shaft speed is very small. The bearing and hollow axis is always in the pure liquid friction and lubrication state, which is not easy to scratch bush. And the bearing capacity of static pressure bearing can improve the oil pressure and the bearing capacity of the oil film. Because the liquid hydrostatic bearing works in the pure liquid lubrication condition, the friction pair surface is not in direct contact, therefore, the small abrasion and long service life can theoretically prolong the service life of the gold ore crusher.

The application of ore milling equipment: Rock, metal ores, alloys, sand, cement, slag, ceramics, catalyst carriers, soil, glass, coal, coke, alumina, metal oxides, plant materials, slag, silicates, etc. The features of ore milling equipment: 1, Small size, light weight, high efficiency. Can be used for material grinding, mixing and machine alloying. 2, High polishing speed and efficiency. 3, By changing the number of samples, the grinding time, grinding media and the number of grinding balls, can achieve very extensive grinding results. 4, Through a dedicated fixture, 12 samples can be ground at a time. 5, After pre-set grinding time, grinding process can be done automatically, without manual operation. 6, Rugged, and very low failure rate. 7, Unique design grinding bottle: the junction of traditional grinding bottle s body and cap is almost at right angles, and the sample gathered here can’t fully contact with the grinding balls. Therefore, its efficiency and grinding effect are bad. The grinding bottle provided by our enterprise has a special design and casting process. The bottle and cap are both designed as curved concave surface, which eliminates the possibility that samples deposit on the dead. So its grinding effect is more uniform and efficient. The analysis and findings made by Hongxing experts: If the mills speed is same, while the grinding time is not, the grinding rate will become lower and lower as time increasing. However, if the grinding time is same, while the mill s speed is not, the grinding rate will become higher and higher as its speed increasing. With the development of technology, Hongxing will study ore milling equipment more and more. We will work with our full enthusiasm to create high quality products for the construction industry and make a contribution to our country.

During the ultrafine mill process, there are two essential processes: The first is dissociation, it means crushing and ultrafine mill the large-sized ore to separate the useful mineral particles from the ore; the second is separation, it means sorting the dissociated mineral particles into different product according to their different physical and chemical property. The vast majority of useful minerals and gangue are in close symbiosis together. If we do not separate the minerals or its components from each other, we cannot sort them even if their property has a big difference. So, the basic tasks of dressing plant are to separate the mineral substance and prepare the suitable material for the next process. So dissociating the useful minerals from the gangue is the prerequisite of any sorting method. The purpose of crushing and ultrafine mill is to separate the useful minerals from the gangue. In addition to a small number of rich ore with useful minerals, the vast majority of mineral is the poor ore with large amounts of gangue. Inappropriate choice of crushing process and the equipment, the poor operations management or the inadequate dissociation of finished product will lead the decline of the technical and economic indicators of the entire dressing plant. The dissociation of useful mineral particles are generating during the process of decreasing the size of mineral. To sum up, the technology indicators and the level of economic indicators of the dressing plant are depending on the crushing process and ultrafine mill process. So each ultrafine mill workers must take seriously the ultrafine mill process and ultrafine mill equipment to minimize the cost of crushing and ultrafine mill. In the dressing plant, the equipment investment, production cost, power consumption and the consumption of steel are the largest proportion of crushing process and ultrafine mill process. To a great extent, the crushing and ultrafine mill equipment determine the economic benefit of the dressing plant.

Currently, with the rapid development of the construction industry, the natural sand cannot meet the requirement of construction industry and other industries. Under this circumstance, ore milling equipment develops quickly. But influenced by the traditional sand making obsolete equipment and the serious pollution problems, the ore milling equipment is also faced with many difficulties and challenges in China. With the accelerated development of China's industrial and urbanization, the consumption of the mine resource is also growing. The supply of mineral resources is in a state of tension, which causes a heavy burden to our country's economic development. Especially in the case of the strengthen of environmental production effort, the traditional sand making obsolete equipment cannot meet the high standard of production requirements, which resulting in the contradiction between the sand making industry supply and demand. On the other hand, the sand making manufacturers are poorly equipped, the scale is small, and the concentration ratio is low. So it is difficult to form a production base scale. In addition, the ore milling equipment lacks systematic standard system. There is also no serious management of the industrial products, which causes the development direction of mining industry is unclear. In the competitive era of ore milling equipment, the sand making companies should continuously attract the advanced technology and focus on the independent innovation and brand building to strengthen the management system and promote the optimization and upgrading of the industry. With the support of new technology, SBM will lead the artificial sand making industry to longer term development.

Due to the exit of Lexmark, only four Canon, Hewlett-Packard, Epson and Brother IV inkjet printer makers were sold in China in 2013. Most of the market share is Canon, HP and Epson this traditional printer occupied by the top three. Although the domestic inkjet printer market capacity in 2013 there have been some changes, but from the major manufacturers of products, whether it is Hewlett-Packard, Canon or Epson, ostensibly emphasizing the concept, in fact, or fight the price, but Some fight the price of the machine, some spell is the cost of supplies.

During that time, although the economy is going down, the days of laser printer cartridge are not very good, but the inkjet printer is unique. As long as home users spend more than a hundred yuan, they can bring a color inkjet printer back home. As low as one in five print costs, allowing users to consider more is that I should print something. The industry consensus that after 2013, the inkjet market will still maintain 10% -15% of the sustained growth, a popularity storm seems to be sweeping the vast land of China.

However, behind all the good things, one overlooks the important issue that home users often have a long replacement cycle. Because the frequency of use is relatively low, there is no requirement on the performance (content only if it can play a word on the line), so long as the printer is not bad, home users generally do not take the initiative to change new ones. There is an old saying in China that "what is the difference between Xiao and Xiao?" Is based on the sensitivity of cost input, and the user psychology of price parity has now become extremely serious.

At this stage the problem is that manufacturers have been very difficult to create a lower printing costs of products, the loss of the sale can not do, even if Canon introduced more high-precision products like cf217a toner cartridge, HP introduced faster print products, home users simply not Do not care about buying, really care about print quality and printing efficiency of the main, not bad money, laser often become their first choice. So in the market saturation, the various data is likely to be difficult to counter-attack within a few years.

For laser printer supplies, although we see more, but very little understanding of the internal structure, which can usually be divided into three categories.

The first is the integration of photosensitive drum, developing roller and toner cartridges integrated design, this cartridge is not designed to allow users to add toner, the reason why the toner cartridge and drum tied together, is to carbon When the powder is exhausted, no matter the life of the photosensitive drum has arrived, the entire cartridge must be forcibly scrapped. This design is widely used in low-end black and white laser printers, the environmental pollution is indeed a great, do not look at the printer's selling price is not expensive, in fact, the profits are in the final supplies, manufacturers can reach more than 70% profit margin, which also To the general supplies to bring opportunities, many users in order to reduce printing costs, even with destructive means to powder cartridge.

Two-piece cartridge refers to the cartridge is divided into two separate parts, part of the photosensitive drum, the other part of the developer roller and toner cartridge, when the toner runs out, only need to replace the toner cartridge of the developing roller , Without having to replace the drum, the cost is relatively low, but the market has been using this design less and less printers.

Three body cartridge refers to the cartridge is divided into three separate parts: photosensitive drum, developing roller, CF230A Toner Cartridges, when the toner is depleted, just replace the toner cartridge can, on the surface of the input is the lowest, everyone Also known as drum separation technology.

Does the drum never need to be replaced? Really beautiful. According to the different photosensitive materials, toner cartridges can be divided into three types: OPC drum, SE drum and ceramic drum. On the composition, the general OPC drum only three layers, the first layer is the aluminum tube, the second layer is the insulation layer, the third layer is the photosensitive layer, short life expectancy, generally only about 3,000. SE drum and ceramic drum surface from four to five layers of material synthesis, especially ceramic drum, the fourth layer is the first protective layer, the fifth layer is the second protective layer, the fourth, fifth layer of hands to protect the light Layer, so long life expectancy, to reach 100,000 pages, so many manufacturers play the word game, shouting slogans for life-free cartridge, in fact, the printer really want to use a high load of 35, photosensitive drums also break the food. Finally, SE drum life is usually about 12,000 pages.

Over past year, the engineering mechanical industry shows a development tendency of first high and then low. Since this year, the government has implemented macro control to the real estate industry, especially since the third quarter of the year, influenced by slow-down high-speed railway investment, macro control on the real estate and gradually tense money market, the sales amount in the engineering mechanical industry has decreased significantly. Faced with such a reality, we need to analyze and research it objectively. Seen from the whole ore milling equipment market, there are many factors that have an influence on the crushing equipment, for example, the prices. The price of the steel, rocks and ores, building materials and even the houses has an effect on the ore milling equipment industry, and then on the price of the crushing equipment. Seen from the current situation, the price of the ore milling equipment is mainly influenced by the steel and the market dynamics. It is reported that the stocks gradually dominate the steel market, and the market mentality is relatively realistic, and these two factors control the price of the ore milling equipment. The tendency of the steel industry may change the price structure of the ore milling equipment. With the significant rising of various steel materials, the transaction amounts in the market shrink, and the price tendency of the market is not clear. Seen from the price tendency of the steel, the risks in short period of time are not high, but if the purchase needs of the downstream users still cannot be effectively released, it is very possible that the price of the steel will continue to rise.

Since its emergence, the gold ore crusher has experienced uneven development over nearly one hundred years due to different research methods owing to the different economic development levels of nations. Although the efficiency of gold ore crusher is very low, it is extensively applied. Domestic research on energy is basically carried out individually and empirically. There haven't been systematic research methods to gain due achievements. The research covers the optimal application, the factors influencing efficiency of gold ore crusher, optimal simplified structure form, transmission mode, steel ball size, matching ball quantity, rotation speed, power, plate, etc. Although gold ore crusher has basically completed its localization, the research and analysis on the gold ore crusher has been staying on traditional level. The traditional design of gold ore crusher is based on the calculation of the thickness of grinding machine barrel. To reinforce plate arrangement, the method of analogy can be adopted. If we simplify gold ore crusher as a beam and calculate the strength according to the plane bending, torsion and deformation, the result can be too rough. The reasons are as follows: 1 There isn't much difference between the diameter and barrel length, so it doesn't accord with the assumption of simplified supporting beam (the beam length can be over five times the maximum size of the cross section) 2 The cylinder body is a kind of plate shell structure, and the deformation under stress is much complex. 3 The cylinder body contains a feed port, a discharge port and lining plate, which may cause stress concentration. So only fine calculation can make nearby stress distribution clear. So the traditional design of gold ore crusher tends to be conservative, and the intensity far exceeds the working condition. Since there is a lot of strength reserve, SBM has made detailed analysis on it. We will continue to make an effort to moderate and research brand new product, which will benefit the long term development of the enterprise as well as the society.

In recent years, a large number of ore milling equipment made in China have been exported to many African countries. After India becomes the early market for mining machines as a developing country, nowadays the African areas will grow to a brand new market with much potential for Chinese ore milling equipment. Africa has always been a promising area for the development of infrastructure construction market because the African government and people are all expecting urgently to improve the local infrastructure construction considering their poor basic building construction. A new round of upsurge for infrastructure construction is coming in most African areas, which will greatly drive the current export of the Chinese ore milling equipment and at the same time form a new business opportunity for the engineering equipment. SBM Mining Machinery Co., Ltd, as a leading enterprise of mining machines in China, has actively taken part in the fierce international competition. Our crushers are exported to the world with progressive increasing exporting amount and they become the best sellers in the African market lately. Up till now, we have exported hundreds of sets of stone production lines from Zhengzhou to Africa. African economy is developing very fast in modern times and the local government starts to invest much to the infrastructure construction and the mineral exploitation. Therefore, the African area has much demand for the mining machines like crushers, ore milling equipments and sand makers. The African countries are unable to make good quality mining equipment so they choose to import these machines from other nations especially China because Chinese ore milling equipment have price advantages, which makes our products preferred by the African countries. Our stone crushers are popular all over the world with its good reputation and high praise from the customers.
