- Operation process:
(1) Check the impeller rotation direction, from the feed inlet, the impeller should go counterclockwise, or should adjust the motor wiring.
(2) Crushers and material handling as follows:
Discharge outlet belt conveyor → PL vertical impact crusher → feed belt conveyor
Crusher must load starting, must wait until after the crusher is operating normally before feeding.
(3) feed size is in strict accordance with the provisions of the various types of feed ban is greater than a predetermined size material into the crusher, otherwise it will cause excessive wear of the impeller and the impeller imbalance, or even cause clogging impeller and center feeding tube so that the crusher is not working properly, when found in the bulk material should be promptly removed.
(4) When the discharge belt conveyor is stopped, it should immediately stop feeding, and should therefore discharge belt conveyor feeding system interlock open, stop. Otherwise it will cause crushed impeller, thereby burning motor.
(5) Should be a uniform continuous feed.
(6) The crusher during operation, without severe vibration and abnormal noise, otherwise, should immediately stop inspection, failure to discharge in order to drive.
(7) During operation of the crusher observe the door should be sealed tightly closed.
2 routine maintenance and safety technology
a. regularly shut down, open the door to check inside to observe the polystyrene crusher wear parts, all wear the collar, lining, impeller liner wear and abrasion degree circumferential shield block, worn should be replaced or patched , wearable pieces should be worn at the same time a full replacement guarantee impeller running balance. Found impeller body wear should be replaced or ask the manufacturer repair.
b. When the non-operation of the crusher open holes in the inner workings of observation, to avoid danger.
c. crusher 3 # lithium grease or molybdenum disulfide grease added in an amount of air bearing 1 / 2-1 / 3, crusher 400h adding the right amount of grease, work 2000h open spindle bearing assembly cleaning working 7200 ~ 10000h, should be replaced with new bearings.
The upper end of the spindle assembly bearing for the swimming side, the bottom bearing the fixed end, after assembly should be able to be pulled by hand pulley and flexible.
d. Drive V-belt tensioning size should be adjusted to fit, to ensure that the V-belt force uniform, dual-motor drive, the V-belts on both sides should be grouped matching, so that the length of each group as consistent as possible, should be adjusted so that the two motor current the difference is not more than 15A.
e. Equipment PL crusher belongs high-speed operation, the crusher operation should pay special attention to production safety, the operator should operate on the specified positions, unrelated persons should stay away from the device, please contact the machine repair.
