The structure of roll crusher is very complex.It mainly composes of roller,roller support bearings, gag and adjusting device, and drive components. Roll crusher is the use of friction roller surface will be broken into bite material, so bear squeeze or split and broken machinery. When used for crushing or need to increase the crushing ratio, often in the roll surface of the teeth or grooves to increase the splitting effect. Roller crusher can be divided into toothed roll crusher and roll crusher, roller crusher which is more important and commonly used.
The principle of the roll crusher is crushing the material in two opposite rollers caught in the park movement, crushed by the continuous function, but with stripping the role of grinding, crushing the ore. If the roll surface is tooth, then the main role of the split pieces of broken. Between two rollers or pads with wedge adjustment device, the top wedge-shaped device with the adjustment bolt, gasket device through changes in the quantity or thickness shims to adjust the feed particle size, when the gasket increases two larger roller gap, when the gasket when the two rollers to reduce the gap becomes smaller, the smaller particle size. Drive mechanism is composed of two motors through V-belt drive to the sheave on the drag roller, according to the relative direction rotation. In the broken material, the material from the inlet through the roller, the rolling and broken, broken after the product discharged from the chassis below.
Roller crusher for cement, chemical, electric power, metallurgy, building materials, refractories and other industrial sectors crushing medium hard materials such as limestone, slag, coke, coal and other materials in the debris, crushing operations.
Roll crusher has many advantages: a simple structure, easy manufacturing, stable operation, simple maintenance, low running costs, adjustable discharge particle size, etc.
