In the production process, the breaker plate and the material acts directly, crushing force is high, particularly when broken greater hardness material, resulting in broken mounting bolts vibrating plate, nut loose, so that crushing plate wear is intensified and a tremendous noise, severe broken off or broken boards to make equipment downtime, affecting the normal production. In such cases, just before starting the tightening bolts, nuts, is not completely solve the problem, according to the actual situation at the scene to analyze specific issues, to find ways to take a practical approach to solve the problem. For example, you can use spring damping device locking plate solve broken loose at work, thus extending the life of the broken plate Xin Li crusher, improve work efficiency. This is done using a spring made of bolts loosening and anti-self-tightening device that springs from inside the gland, springs, outer spring gland composition, this means wearing tighten the nut on the bolt, nut the spring is compressed to a certain extent After a very strong anti-vibration effects, powered by a huge bolt loose crushing force generated by the spring tension automatically compensate, so Buzhi Yu loose bolts, thus extending the life of the broken plate crusher uses, improve production efficiency . In short, in the course may want specific solutions to specific problems circumstances prevent crushing plate loose, increased wear, broken, etc., in order to extend the life of broken plates, reduce costs and improve efficiency. Roll crusher also called on the roll crusher, double roll crusher, roll crusher, is the use of the roller surface friction material will be broken into bite crusher structure, so bear squeeze or split cracked and broken machinery. Roll crusher usually divided by the number of roller single roll, double roll and multi-roll crusher is mainly used in mining, metallurgy, chemical industry, coal industry coarse brittle bulk materials, intermediate crushing, feed their large size, discharge size adjustable, compressive strength of the material ≤160MPa crushing. Especially in the coal industry, the use of the raw coal crusher, long after iron removal, cleaning, no addition to the gangue, can directly impact crusher broken, broken out of the material, uniform size, broken too low, thus simplifying the selection coal technology, lower investment and production costs.
