Jaw Crusher

Jaw crusher are ideal for primary and secondary crushing. With the increase of production, our jaw crusher can greatly reduce the operating costs. And it is of reliability and flexibility. The large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our jaw crusher can increase the capacity.

Jaw crusher has been widely applied in mining, metallurgical, construction, road and railway building, water conservancy and chemistry etc. It is mainly applied in the primary crushing in which the compressive strength of original material is under 320Mpa.

Features and Benefits

1. Simple structure and easy maintenance.

2. Stable performance and low operating cost.

3. High crushing ratio.

4. Use high manganese steel, one-off foundry.

5. High resistance to friction, abrasion and compression with longer operating life span.

Working Principle

Jaw crusher machine uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening.

Operation and Maintenance

1. The jaw crusher should be greased and oiled regularly; this should be done prior to each use. To do this, simply turn all grease caps one full turn (clockwise) and put a few squirts of oil in both of the oil cups. If grease caps are tight, add more grease (see MAINTENENCE below).

2. Check jaws for cleanliness and clean them if needed. Loosen the wing nuts and remove the front shield, then loosen the hopper wing nuts (located below the hopper on the left and right of the machine) and move it up and back so that the jaw cam lock is exposed. Lift the cam lock up to release the stationary jaw so that it may be lifted straight out.

If it is jammed, the cam lock may be freed by tapping lightly with a mallet or ball-peen hammer. Once the stationary jaw has been removed, the movable jaw will be exposed inside the machine. Brush both jaws with a large bristle brush. If any residual sample material adheres to the jaws, it may be removed by brushing with a large stainless steel bristle brush.

After brushing, blow the jaws off with compressed air. The hopper and sample collection trays should not be brushed, but should be blown off with compressed air. Reassemble the jaws and put the sample hopper back in place, hand-tightening the wing-nuts and replace the front shield.

3. Adjustment of jaw spacing: Turn the circuit breaker (located in the breaker box) to the "ON" position. While the crusher is empty, start the machine and allow it to come up to full speed. The machine must be adjusted while running. Loosen the square-head bolt (left). This will allow the hand knob (or right) to turn.

Slowly turn the hand-knob clockwise until the jaws of the crusher can be heard just touch
