Especially for the development of large Raymond mill, there is no mature experience to learn from, and no mistakes are allowed in the design. Therefore, it is necessary to improve the design efficiency and quality, and enhance the independent innovation ability and market competitiveness of enterprises by virtue of the integration of multi-disciplinary technologies. On the basis of the integration of Raymond mill, computer technology and network technology, the trend of digital development has been formed. Recalling the development history of crusher, there are mainly jaw crusher, impact crusher, conical crusher, hammer crusher, ultra-fine crusher, roll crusher, impact crusher and so on. There are many kinds of crushers, so they have different names. Vertical crusher (the main shaft is vertical) has become a hot-selling crusher product with breakage instead of grinding since it was introduced in the 1980s. As a fine crusher, its average discharging granularity is less than 3-4 mm and 90% is fine powder, which reduces the feed granularity of the ball mill and increases its output by 20-30%. After more than 20 years of development and evolution, vertical crusher from the first generation to the fifth generation, from a single blow crushing evolved into impact crushing, the service life of the hammer head is four times longer than that of the old crusher. Vertical impact crusher, the representative product of vertical crusher, is widely used in material grinding engineering in iron ore, gold mine, cement, glass, ceramics, electric power and iron and steel industry.

The cement sand making machine is a new type of sand making equipment designed and manufactured in accordance with the similar characteristics and market needs at home and abroad.In 1970s, our country introduced the eight-hole cement sand making machineabroad.It uses river sand and a small amount of fly ash and cement to suppress lime sands.However, the rotation of the disc can only press one piece of sand at a time, and the output is low. When the large amount of industrial waste fly ash is used, there is a stratification phenomenon in the lack of exhaust. It cannot meet the requirements of the national wall reform and not meet the national industrial policy at that time.In order to improve the output and make up for the disadvantage of easy delamination of the defective products, the domestic mechanical engineers have developed a crankshaft type double crank mechanical pressing machine with two blocks, three blocks or even four blocks. Because of its special pre pressure buffer design and the adjustment of the depth of the material, it can be qualified for the national policy of industrial structure of the new wall material with large amount of fly ash as raw material.The equipment inherits the eight-hole turntable type sand press without the need of the bracket, the advantages of the direct palletizing, and the stability and reliability of the mechanical motion, and 15~17 times a minute to ensure the production and quality of the single equipment.

If the global new energy vehicles, especially the pure electric vehicles represented by the US Tesla, grow faster, the global demand for calcium carbonate will reach 350,000 tons by 2010. As for the supply of calcium carbonate, there will be a gap in the supply and demand of global calcium carbonate by 2019. Calcium carbonate beneficiation equipment includes crushers, ball mills, jigs, flotation machines, etc., as well as some auxiliary equipment to form a complete production line. The hand selection method is a sorting method based on the difference in color and appearance between calcium minerals and gangue minerals. The selective particle size is generally 10 to 25 mm, and the determination of the lower limit of the particle size depends on economic benefits. Hand selection is the earliest method of mineral processing used in the history of calcium mine production. In addition to spodumene, the hand selection is also used to pick calcium concentrates from lithionite, petalite, and amblygonite.The hand selection method has been generally replaced by flotation or other methods due to its high labor intensity, low production efficiency, and large waste of resources.

1. Digestion efficiency is high. Considering the characteristics of limestone digestion process, a comprehensive water-adding curve is designed with different nozzles to keep a certain humidity in the digestion process. At the same time, a special digester is used to stir the blades, which produces strong stirring to the limestone in the digestion process, and greatly improves the digestion efficiency of limestone. 2. The blade is non-sticky. The front and back nozzles are installed on each stirring blade of digester by water-adding nozzle. The impeller of quick limestone stirring is washed in front and back once every turn, so the blade will not stick. 3. Good environmental effect. Because the front section of limestone digestion is equipped with a sealing section matching spiral blade and circular shell, the steam and dust generated during the digestion process of limestone slakers will not be emitted from the inlet and outlet of the limestone digestion section. It avoids the steam from the inlet and outlet of the limestone digestion device from encountering an electronic scale or spiral scale into water. The sticky mud on the scale pole affects the accuracy of the scale, and the digested quick limestone is discharged in. So without dust, environmental protection effect is good.

Mixed crushing refers to the limestone production process in which two kinds of raw materials are fed into a crusher in a certain proportion for crushing. Common mixed crushing are limestone and marl, limestone and shale, limestone and clay, etc. Screening raw materials before crushing, only crushing the screening materials, often can achieve good results. For example, nowadays cement is produced by a new dry process with pre-decomposition, which improves the silicic acid rate in the raw material mixing, and often needs to be mixed with siliceous raw materials. The contact between the jaw plate and the machine surface is not stable; the eccentric shaft rotates too fast to remove the crushed materials, which results in jamming of the crushing chamber and wear of the jaw plate. Material properties have changed, but the crusher has not been adjusted in time; the angle between the movable jaw plate and the fixed jaw plate is too large to exceed the normal range; The strength and wear resistance of the jaw plate are not good.

No Picture
When the crushing force acts on the frame, the talc mill occupies less space than the large cone crusher, produces less deformation to the installation base, and has greater production capacity than the jaw crusher. The disadvantage of the talc mill is that the crusher concentrates on the center of the talc, so it needs a high-strength shaft, bearing and supporting mechanism. talc mill has been used as supporting equipment for E-crusher, cone crusher and other crushers, as a secondary crushing of materials, that is to say, talc millhas been in a supporting role. Talc mill can be used continuously for more than one year. When the wear is serious, the cover can be replaced by removing it. Small maintenance and low cost are incomparable to any other type of crusher in China. The talc gap of the abrasive talc body of thetalc mill can be adjusted arbitrarily from 1 mm to 20 mm. After adjusting the talc gap according to the requirement of crushing size, the crushing size can be conttalced reliably, and all of them are discharged from below the crushing chamber with ideal size.
add to favorites the grinding effect naturally diminishes Pc

At higher rotation rates, the raymond mill is in a throw-down state, and the situation is complicated in the throwing state. At a certain filling rate, as the turning speed increases, the raymond mill will change from a plunging state to a throwing state. However, at different filling rates, the rotation rate required for the raymond mill to change from leeching to throwing is also different. The filling rate is higher and the rotation speed required to change to the throwing state is higher. Conversely, with less ball loading, the grinding effect naturally diminishes. In terms of mechanical phenomena, the ball is loaded, the power consumption is greater, and the mill productivity is also large. In addition, the material in the mill also includes ore and water, and there is a certain gap between the actual power and the theoretical power. In summary, we can know that at different speeds, the filling rate has a corresponding adaptation value. The fitness value is not as high as possible, and how to find the adaptive filling rate needs to be judged by experiment.
add to favorites Marble Gangue Crushing Industry Pc

Marble gangue is a kind of solid waste discharged from marble mining and marble washing. It is a kind of black-gray rock with lower carbon content and harder than marble. In real life, if the gangue has not been treated by crusher and other equipment, it will seriously damage the environment. From the point of view of marble mining process, China produces 100 million tons of marble annually and discharges about 14 million tons of gangue. From the point of view of marble washing and processing, 20 million tons of gangue will be discharged per 100 million tons of coking marble washed, and 15 million tons of gangue will be discharged per 100 million tons of power marble washed. From these data, we can see that the discharge of marble is huge. A large number of piled marble not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater by leaching water of marble. Marble gangue contains certain combustibles, which occurs naturally under suitable conditions and pollutes the atmosphere by discharging harmful gases, affecting the health of residents in mining areas. Therefore, the treatment of marble is imperative.
add to favorites Working principle of ball mill Pc  
No Picture
The working principle of ball mill is that the motor drives the cylinder to rotate through the deceleration device. When the cylinder is rotated, the crushed ore and steel balls are brought to a certain height by the friction force and centrifugal force of the lining plate. As a result of gravity, the ore will be thrown down and dropped, and the ore will be gradually crushed under the impact and grinding action. The crushed ore is discharged out of the barrel through the discharging part. After the discharged minerals are classified into qualified products in the screw classifier, the coarse sand is returned to the ball mill through the combined feeder to continue grinding. The feeder feeds continuously and evenly, the ore enters the ball mill continuously and evenly through the combined feeder, and the grinded materials are discharged continuously from the ball mill. Ball mill is a continuous grinding equipment which can work 24 hours a day.

The newly installed jaw plate must be fixed tightly, installed well, and the surface of the jaw crusher contacts smoothly. A layer of material with good plasticity can be padded between the jaw plate and the surface of the jaw crusher. Every batch of materials entering the crusher should be sampled and checked. Once there is a great change in the nature of the materials, the parameters of the crusher should be changed in time to match the materials entering the crusher.
