Breaking is the process of turning large granular materials into small granular materials by external force, and the machine used is called a crusher. The process of turning small particle materials into powder materials by external force is called pulverization or grinding, referred to as grinding. The machine it uses is called a grinding machine. The combination of crushing and grinding is referred to as grinding, and the machine used is referred to as grinding machine.
In the beneficiation industry, crushers generally process larger pieces of material, which are coarser in size, usually greater than 8 mm. Its structural feature is that there is a certain gap between the crushing members, and they do not touch each other. The crusher can be further divided into a coarse crusher, a medium crusher and a fine crusher. Generally speaking, the material processed by the grinding machine is fine, and the particle size of the product is fine particles, which can reach 0. 074 mm, and even finer. The structural feature is that the crushing components (or media) are in contact with each other, and the medium used is steel balls, steel bars, gravels or nuggets. However, some machines have both crushing and grinding effects, such as self-grinding machines . ∮ 5. 5 × 1. 8 meters from the mill to treat the ore particle size upper limit of 350 ~ 400 mm, product fineness up to -200 mesh accounted for about 40%.
Crushed cement: cement production process, most of the raw material to be crushed, such as limestone, clay, iron ore and coal. Limestone is the raw material for producing the largest amount of cement. After mining, the particle size is larger and the hardness is higher. Therefore, it needs to be crushed by crusher, such as jaw crusher , impact crusher, cone crusher , impact crusher (sand making). Machine) and so on. The crushing of limestone occupies a relatively important position in the material crushing of cement plants.
Needle roller punching machine series
The punching machine is a kind of mechanical equipment that is driven by the power mechanism after the raw material is installed, and the punching die acts on the material to complete the punching. The punching machine can perform operations such as sheet processing, stamping, molding, embossing, etc. that force metal into the mold.
