Crusher in the overhaul, after the repair is completed, the no-load test time, usually 2 ~ 6h, time can also be determined depending on the circumstances. Before commissioning the crusher, if eccentric shaft rotation crane cranes week to determine when unimpeded compound crusher, before driving. Load car should meet the following requirements: (1) the start and stop the program starts, the electrical part of the system shall comply with the relevant chain maintenance requirements; (2) the fastener should be firm, not loose; (3) lubricate all lubrication points normal Simmons crushers, no leakage; (4) bearing temperature should not exceed 30 ℃; (5) the flywheel steady rotation; (6) all flexible adjustment mechanism, and achieve the required adjustment range. Load test after passing the test should be carried out load. Load test of time, usually 2 to 3 days and nights. Load test meet the following requirements: (1) crusher may be cyclical and significant impact sound; (2) bearing temperature should not exceed 40 ℃; (3) crushed product size that is the port of discharge gap to meet the requirements. Jaw crusher installation should pay attention to what matters jaw broken machine load test: (1) Jaw Crusher continuous operation 2h, bearing temperature rise should not exceed 30 ℃; (2) Jaw Crusher All fasteners should be firm, not loose phenomenon; (3) flywheel, sheave smooth operation; (4) all friction jaw broken machine parts without scratches, chipping and grinding phenomenon, no unusual sound; adjusting means (5) jaw crusher machine nesting population should be able to to ensure that the nesting population adjustment range. Jaw Crusher load test when: (1) crusher or may not have a significant impact on cycle, percussion; (2) the maximum feed size should meet the design requirements; (3) continuous operation 8h, bearing temperature must not exceed 30 ℃ ; (4) the crusher capacity and product size should meet the design requirements; Room (5) Adjust the seat and the seat frame no shifting of the ear. Preparation before jaw broken machine use: (1) The joints carefully check whether there is enough thrust plate grease; (2) Carefully check all the fasteners are tightened; (3) double-check the belt is good. If it is found there is insecurity, should be replaced, cone crusher when there is oil on the drive belts or pulleys, oil rag and wipe application; (4) Check guard is good. When there is insecurity found should be immediately removed; (5) Check whether the ore crushing cavity or debris. If ore or debris, then, must be clean in order to ensure that the crusher cavity start; (6) Check whether the return from the top bolt, spacer group is pressed, whether the T-bolts tightened.
