1、 Structural characteristics of claw crusher:
The main working parts of the claw crusher are the flat teeth installed on the rotor, and the elemental teeth have the ability to crush various granular raw materials. A claw crusher is a mechanical device that uses high-speed rotating claws to crush feed. It has the advantages of small size, light weight, fine product particle size, high working speed, easy installation, operation, and maintenance. The commonly used types include 9FJ-280, 9FJ-300, and 9FJ-350, which are currently widely used economical crushing equipment. The toothed claw crusher mainly has an upper body Machine cover Rotor assembly Screen the pieces Feeding device The machine frame consists of six parts, and the body and rotor assembly together form the crushing chamber. The rotor assembly is the main component, and the crushing of materials is completed in the crushing chamber.
2、 Basic structure and working principle of claw crusher:
The toothed claw crusher mainly consists of a feeding hopper, a casing, a rotor, a toothed disc, a sieve, a machine base, a motor, and other parts. After the material enters the crushing chamber, it is rapidly crushed into fine powder and slurry under the continuous impact and rubbing of the grinding hammer and teeth. Under the action of centrifugal force and airflow, it is discharged outside through the sieve hole and the discharge port.
3、 Installation and commissioning of claw crusher:
1. The crusher can be fixed on a cement foundation or on a frame made of steel or hardwood. The length of the triangular belt can be determined according to the distance of the frame it is fixed on.
When using a tractor as the power source, a separate frame can be made for installation, and our factory is responsible for matching the pulleys required for the diesel engine.
3. Regardless of the power used, attention should be paid to the speed of the crusher, and the belt pulley should be replaced to meet the requirement of 4200-4600 revolutions per minute for the crusher.
4. The circuit and switch are reliable, and the working voltage is stable.
5. Before testing the machine, check whether the belt tension is appropriate, whether the speed is reasonable, whether there is oil in the lubrication area, and whether the screws in each part are loose. If there are any defects, they should be eliminated before starting the machine. Run it idle for 2-3 minutes until it is normal before feeding and working.

5、 Common faults and troubleshooting
Fault phenomenon, fault cause, exclusion method
Blockage or backflow 1, excessive feeding amount 1, reduce feeding amount
Low rate 1, spindle speed too low 2, high moisture content of hammer material 3, high moisture content of material 1, adjust the tightness of the transmission belt 2, replace 3, air dry
Bearing temperature rises by 1, feeding amount is too large by 2, bearing oil shortage by 1, reduce feeding amount by 2, and add lubricating oil
There are abnormal vibrations and noise. 1. Loose fasteners. 2. Unstable machine base. 3. Unbalanced rotor. 1. Tighten bolts. 2. Flatten machine base. 3. Remove rotor and rebalance
