Teeth roll crusher double roll crusher teeth and four teeth roll crusher two double teeth roll crusher mechanical spring-loaded, the device can be equipped with coarse toothed roller or, respectively, according to the the broken material properties and requirements gear roll, four roll crusher teeth by two double teeth roll crusher combination; teeth roll crusher for coal, metallurgy, mining, chemicals, building materials and other industries as well as large-scale coal mine or coal preparation plant raw coal containing waste rock broken; teeth roll crusher capacity, between the motor and reducer to limit fluid couplings from the connection to prevent power overload sensor overload protection, safe and reliable. Tooth roller spacing hydraulic adjustment, the tooth roller bearings centralized lubrication. Toothed design optimization, pull shear select crushing efficiency and low consumption, the grain is uniform. Performance characteristics has the dual function of screening and crushing two teeth roll axis fixed installation, their relative motion as a rotating grate, meet the size requirements of materials leave out to achieve the initial screening first tooth the roller or teeth roller with liner gap points, thus avoiding that part of the material through the the roller teeth again broken, not only reduces the material over broken rate and energy consumption, reduce the roller teeth broken time, extend the service life. While the teeth opposing roller speed differential operation, and has better shear and tensile crushing effect. The the roller tooth movement also makes mandatory discharge after crushing of materials, and easy to produce congestion, thus also suitable for viscous materials with high moisture material. The two teeth roller non-round, non-engagement, non-constant speed operation of the characteristics greatly increase the shearing effect of the mineral aggregate, reduced tooth roll crusher at home and abroad clogging. 3. The double overload constant filling fluid coupling on the one hand the impact absorption crushing machine running smoothly, and the other hand on the machine to play a security role, once inside the device stuck or overloaded, hydraulic coupler is automatically cut off the transfer of power to the motor idling, which play a protective role in motor and large and small teeth roll; This machine is equipped with a moving jaw buffer overload teeth roll crusher force will force the radial compression spring relocation in order to increase the gap between the tooth roll and the jaws, the toothed rolls and the jaw body at the same time to play a protective role. Flexible assembly, easy maintenance toothed roller shaft assembly with inlaid broken ring gear, ring gear teeth sets, bolted. When wear sets of teeth in the crushing process reaches a certain level, can be replaced individually, speed, thereby reducing downtime and lower production costs.
