broken jaw crusher is widely used in many industries machinery
Stone Crusher, it has a simple structure, reliable operation, easy maintenance and repair, the production cost is low. Jaw crusher operation and maintenance is very important, including the start and stop operation of the crusher, the correct starting and stopping will help improve the production capacity of the crusher.
1) Preparations ① Check before driving
main components are in good condition, fastening bolts and other connections loose, the safety device is complete; ② Check the feeding equipment, transportation equipment, electrical equipment is intact; ③ Check lubrication device is good, check the cooling water valve is open.
2) Start with the normal operation
① follow the rules and drive. That drove the inverse order of the production process; pay attention to the control cabinet ammeter indication ② start the main motor, after 20 s ~ 30 s, the current will be reduced to the normal operating current value; ③ regulation and control feeding, so feeding uniform, materials particle size of not more than 80% to 90% import width; ④ general sliding bearing temperature should not exceed 60 ℃, the rolling bearing temperature should not exceed 70 ℃; ⑤ When the automatic tripping of electrical equipment
Quarry Crusher, if unexplained, non-forcible consecutive starts; ⑥ occurred mechanical failures and accidents, should be immediately stopped.
3) correct operation
parking ① parking in reverse order, that is, the production process along the direction of the operation and driving sequence; ② must be completely stopped after the crusher to stop working lubrication and cooling systems, in winter should be let go in the bearing cooling water, avoid bearing is the cracking; ③ after stopping to do the clean up and inspect all parts of the machine work.
