Jaw Crusher
Technological Functions
A jaw crusher is used for the processing of hard raw materials, for the initial crushing of large blocks of shale, coal gangue and other hard raw material in the manufacturing of heavy clay bricks.
Structure and Principles
The motor-driven belt and pulley generate reciprocating movement of the jaw through the eccentric shaft.
When the jaw rises, the angle between the elbow plate and the moving jaw becomes larger, thus pushing the moving jaw plate closer to the fixed jaw plate, while the material is crushed and chopped down.
When the jaw lowers, the angle between the elbow plate and the moving jaw becomes smaller, thus the moving jaw plate leaves the fixed jaw plate under the action of the lever spring, meanwhile the crushed material is discharged from the undercut exit of the crushing cavity.
The motor continuously rotates and the jaws make the periodic movement of crushing and draining, thus enabling mass production.
Features
Compact structure, strong compression force.
Less noise and dust.
User-friendly operation and maintenance.
Faster throughput, more efficiency.
Durable, pressure-resistant design.
Double Hammer Mill
Technological Functions
A double hammer mill is used for the secondary and final crushing of hard materials, such as coal gangue, shale, coal slag, mine slag and other brittle materials below medium hardness with low water content, mainly done by direct striking force.
Structure and Principles
When operating, the motor drives the rotor for high-speed rotation, the material evenly enters the crusher cavity, the fast moving hammer head impact, shear and tear the material, meanwhile the material's own gravity pulls itself from the high-speed rotating hammer and dashing towards the board, sieve strip, leaving materials larger than the perforation size remained on the plate to be continually impacted and stroke by the hammer until they are crushed to the required mesh size, then discharged out of the machine through the sieve plate.
Several rows of hanging hammers are mounted on the spindle of the crusher. The pin holes run through the pin shaft at its circumference, re-hinging hammer between the rows of hanging hammers with the pin shaft, and the working surface can be changed after the hammer is worn.
Features
Double rotor two-stage crushing (up and down), high efficiency design.
Two sets of connecting rotors, upper rotor hammer head crushes the material then picked up by lower rotor hammer for another round of crushing, material crashes and collides inside the inner cavity at high-speed, thus serving the purpose of fine crushing before discharge from machine.
No screen net bottom, preventing blockage in case of moist material, applicable for raw material with water content above 8%.
Unique bidirectional gap-tuning design, the gap between hammers and lining board can be adjusted from the center, such as, the gap can be adjusted to be smaller, when the hammer wears out, and the material mesh size becomes larger as the gap between hammer and lining board widens. The lining board can also be pushed inward to adjust the gap and control the mesh sizes.
