Tooth roll crusher is a kind of roller crusher, which is also commonly used for short. Toothed roller broken work mainly consists of two relative rolling teeth roll chewed up the material, as a result of the toothed roller rolling speed is relatively slow, as a result, the output of per unit time and broken material smaller, too often produce 5-50 tons, compared with other type of crusher crusher, even if is a large number of toothed roll crusher is no longer competitive in terms of unit production. But the tooth roll still has many advantages, such as not only the insurance device, can avoid the hard material to cause damage to the roller surface, extending the overall service life. Moreover, it is the unique design of roller crusher, which makes roller crusher have more special use and function. In this paper, a large scale professional tooth roller broken tooth roller is used in this paper, which is a simple introduction to the double-tooth roll crusher.
What are the advantages of a double tooth roll crusher
1. It has dual functions of screening and crushing
Two toothed roller fixed installation, their relative motion as a rotating grizzly, satisfies the requirement of particle size of the material first by roll or tooth roller and liner clearance leakage achieved preliminary screening, in order to avoid that part of the material passes through the roller tooth broken again, both to reduce the material crushing rate and energy consumption, and reduced the roller tooth broken time, prolong the service life. At the same time, it can make the gear roll at the same speed, and have better shear and tensile breaking effect. The roller tooth movement also causes the material to be forced out after crushing, not easy to generate congestion, so it is also suitable for viscous materials and high water content.
2. Two teeth rolls are not equal to circle, non-meshing and non-uniform operation
This feature greatly increases the shear fracture effect of ore material, and reduces the existing blockage of tooth roll crusher at home and abroad.
3. Double overload protection
Type A, limited moment hydrodynamic coupler on the one hand, to absorb the impact of the broken when the machine run smoothly, safety protective to the machine again on the other hand, once stuck or inside the equipment overload, hydraulic coupler is automatically cut off the power transfer, make the motor idling, thus to protect motor and big, small toothed roller.
B, the machine is equipped with jaw buffer device, when tooth roller for crushing force overload forced compression spring to increase the radial horizontal offshoring teeth roll and the space between the jaw, the tooth roll and jaw body protection at the same time.
4. Flexible assembly and convenient maintenance
The gear roller is equipped with broken gear ring, insert gear sleeve, and bolt is fixed. When the wear of the gear in the crushing process reaches a certain extent, it can be replaced individually and quickly, thus reducing the downtime and reducing the production cost.
5. Reasonable structure and long life
The crushing roll teeth are arranged in a special spiral, which is convenient for the discharge of materials that meet the requirements of grain size, and also reduces the number of roll teeth of the teeth roller at the same time, which is conducive to crushing bulk materials. At the same time, the double action of the tooth roller and the lining plate and the jaw body is used to realize the crushing of the material, reduce the load of gear tooth, improve the crushing efficiency and prolong the use time of the whole machine.
Double tooth roll crusher use range
Roll crusher is suitable for the cement, chemical, electric power, metallurgy, building materials, refractory materials and other industries crushing medium hardness materials, such as limestone, slag, coke, coal and other materials in the broken, finely homework. Is mainly used in mining, metallurgy, chemical industry, coal and other brittleness block material of coarse, intermediate crushing, it into the grain-size, discharging granularity is adjustable, can fight pressure strength of 160 mpa or less materials are broken. Especially in the coal industry, the use of native raw coal fragmentation, as long as after iron, removing impurity, without gangue removal, can be directly crushing, crushing material, granularity excessively low broken rate, thus simplifies the coal preparation process, reduce the investment and production cost.
The working principle of double tooth roller crusher
The double tooth roll crusher is composed of two rotating gear opposing gear. When the roller is rotated, the teeth of the roller surface can hold the coal and break it, feeding the upper part of the coal, and the broken product will be brought out from the lower part of the tooth roll. Broken product particle size is determined by the gap between the two tooth roll surface, when a large piece of hard material into the crushing cavity can not be broken when, toothed roller stress increases, the movable bearing compression spring, increase on the two teeth roll gap, from hard objects, and then borrow spring restoring force makes the movable teeth roll back to its original position.
