Teeth Roll Crusher

Overview

Teeth Roll Crusher refers to the crushing machinery whose discharging size greater than three millimeters is more than 50% of total discharging material, and the teeth roll crusher is one kind of crusher. Teeth roll crusher is formed with roller bearing, roller support bearing, pressing and adjusting device, as well as driving devices, with characteristics of large crushing ratio, simple structure, reliable work, easy to maintain, low operating cost, etc. Teeth roll crusher is one kind of crusher which bites material to crushing area with its surface friction to crush by squeezing or splitting. When the teeth roll crusher is in work or the crushing ratio needs to be increased, teeth or grooves will be made on the roll surface to increase the splitting effect. Roll crusher or roller crusher can be usually pided into single roller, double rollers and multi-roller according to the number of roller, and it is mainly used for crushing brittle mines and rocks with medium or lower rigidity, such as, coal, limestone, cement clinker and feldspar. Teeth Roll Crusher is also widely used to crush materials with medium hardness in the cement, chemical, electric power, metallurgy, building materials , refractory and other industries, such as, limestone, coke, coal and so on.

Working principle 

Wedge or gasket adjusting device is equipped between the two rollers of the crusher, and the top of the wedge device is equipped on the adjusting bolt, so when the adjusting bolt pulls up the wedge, the wedge will move the roof roller away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the discharging size becomes larger; while when the wedge falls down, the rollers decrease the gap between the two rollers under the compression from the spring, and the discharging size becomes smaller. The gasket device can be adjusted by changing the quantity or thickness of the particle size of gasket material, when gasket increases, the gap between the two rollers becomes larger; and when gasket decreases, the gap between the two rollers becomes smaller.
