Introduction to Roller Crusher
Pair-roll crusher, referred to as double-roll crusher or double-roll crusher, is a relatively old-fashioned crushing equipment. After numerous upgrades and transformations, the manufacturing process is more mature. The structure of the equipment is simple, and there is little phenomenon of over-grinding. The shape, size and arrangement of the teeth on the roller surface can be changed according to the properties of the material.
It can carry out medium and fine crushing on medium-hard and soft ores. For example, in a sulfuric acid plant, a pair of roller crushers are usually used to crush pyrite ore once to make the diameter reach 20~30mm, and then enter the double-roller crusher for secondary crushing. Crushed to make the ore diameter less than 5mm, which meets the requirements of fluidized fluidized furnace.
Working principle of roller crusher
The double-roll crusher has two high-strength wear-resistant alloy rollers, and the high extrusion force generated by the relative rotation crushes the material. Under the action of pressure and shear force, through extrusion, shearing and grinding, the material is crushed into the required particle size and then sent out from the conveying equipment.
Application scope of roller crusher
The roller crusher is suitable for crushing medium and high hardness materials in metallurgy, building materials, refractories and other industrial sectors. It is suitable for coarse and intermediate crushing of brittle blocky materials in industries such as cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines, etc. The input particle size is large, the output particle size is adjustable, and the compressive strength is ≤160MPa. materials are crushed. Especially in the coal industry, when using this machine to crush raw coal, it can be crushed directly after removing iron and impurities without removing gangue. The crushed materials have uniform particle size and low over-crushing rate, thus simplifying the coal preparation process and reducing investment and production costs.
