New toothed roll crusher when compared with similar products at home and abroad, the difference is mainly manifested in the following aspects:

(1) with screening and crushing double function

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. Tooth roller differential phase running at the same time, has better effect of shear and tensile breakage. The roller tooth movement also makes material after broken by compulsory eduction, not easily get congestion, and therefore suitable for viscous material and the moisture content is higher.

(2) two teeth roll round, such as the meshing, the constant speed operation

The characteristic greatly increase the shear breakage effect of mineral aggregate, reduces the blocking phenomenon existing in current toothed roll crusher at home and abroad.

The classification of HuaHong toothed roll crusher:

Double toothed roll crusher structure and working principle

Double toothed roll crusher to the general assembly has left and right type, from one end tooth roller, mobile rack, motor and the belt wheel in the left side, according to the left, the right person for the right type.

Double toothed roll crusher is mainly composed of a pair of tooth roller, two pairs of two reduction gear, belt wheel, gear roller mobile rack and rack, etc.

Belt wheel installed on the shaft sleeve, sleeve by hook button fixed on the shaft, belt wheel by insurance pin and bushing together, and deliver the torque. When overloaded in insurance sales immediately cut off, tape bye. Drive shaft supported by two bearings, of which is equipped with gear. Driving gear shaft also has two sliding bearing support, its one end is equipped with gear and shaft gear meshing, the other end of the gear and driven gear meshing tooth roll shaft. Driven gear installed on mobile rack. Into the big materials within the time when the crusher, driven gear by moving the compression spring on the shelf, move behind, expand the toothed roller clearance and discharge large materials.

Double toothed roll crusher is mainly composed of motor, through the triangle belt, driving a pair of intermediate gear, drive gears, in active teeth roll again on the other side a pair of gear drives the driven gear, thus formed the relative motion of the two teeth roll material crushing.

Teeth roll mobile rack is mainly composed of mounts, bearing seat, springs and tighten bolts.

Driven gear roller installed on the mobile rack. Teeth roll mainly by compression spring by tightening bolts top tight to adjust the tooth roll back pressure and bearing clearance. Tooth roll back to the greatest extent, should be to not out of two gear mesh for the principle.

Crusher teeth plate have four specifications. After selection, according to the technological requirements and broken material particle size to choose. Crushing plate with removable commonly. They bolted respectively on the roller.

HuaHong toothed roll crusher installation:

(1) toothed roll crusher before installation, first to deal with the whole equipment to conduct a comprehensive inspection, check and cleaning. Should be no damage and missing parts;

(2) calculating the base load. Crusher whether installed on the ground or floor, shall be on the basis of calculating the bearing load, the power coefficient is generally desirable equipment 6-8 times of the total weight;

(3) check toothed roll crusher foundation bolt and the various parts of the equipment size;

(4), after installation frame. Between the frame and concrete foundation or floor beam pad with hard wood or rubber, in order to reduce the body vibration of foundation load. Looking for is frame, then available bolts should be fixed;

(5) is installed on the driven gear roller mobile, fixed tooth roller follower, then tighten the screw nut with a wrench, compression spring, if in order to achieve the body enters difficult to crushing of minerals, forced the spring compression affects the driven gear roll backwards, increase two teeth roll gap, eliminate mineral;

(6) about moving the rack should match the compression degree of the two groups of spring, the tolerance shall not be more than plus or minus 2 mm.

(7) with active teeth roll. Must pay attention to when installation, should make a toothed roller teeth in the middle of their another toothed roller teeth. That is to say, in the other four teeth teeth roll on the diagonal intersection;

Toothed roll crusher toothed roller (8) after installation, two teeth roll mouth teeth bending side should be the same as that of rotation, there should be no axial channeling two toothed roller;

(9) toothed roller clearance, and the gear meshing clearance can be reference to the demands in the first chapter is looking for;

(10) toothed roll crusher after installation of a fixed axis level should not be more than 0.5/1000;

(11) two triangle belt wheel of parallelism, and the wheel groove center is not coincidence degree also should comply with the request in the previous chapter;

(12) and, finally, crusher cover installation, connection into the feeding chute and funnel. All should add rubber gasket between the flange seal, to decrease the coal dust pollution of air, improve the working conditions and health.
