How to deal with the abnormality of the superfine pulverizer to reduce the loss
The superfine pulverizer has powerful functions and is widely used. However, abnormalities will inevitably occur during the use of the equipment, which may affect the production situation, or cause the production line to stop, and the loss is immeasurable. Therefore, when encountering some exceptions, we should master certain handling methods.
The parts of the shredder are damaged or fall off, or if hard objects such as rocks or iron enter the machine, there will be abnormal noises. The inspection should be stopped immediately, and the damaged parts should be replaced or the hard objects should be removed. The main reasons for low production efficiency are insufficient motor power, improper pulley preparation, belt slippage, severe hammer wear, uneven feeding or excessive moisture content of raw materials. If the above situation occurs, you can take corresponding measures to solve the problem, or replace the motor or pulley to increase the speed, but it must not exceed the rated working speed; or adjust the belt tightness, or replace the belt, or replace the hammer. In operation, the feed should be uniformly added in small amounts and quickly to maintain continuous uniformity; over-wet raw materials should be dried and then crushed for processing.
For the operation and use of the ultrafine pulverizer, after unpacking, first carefully check whether the equipment is damaged during transportation, and then put the electrical control devices of the high-speed machine and auxiliary machines in place, and then connect them to the pipelines of the main and auxiliary machines. When the flange of each nozzle is assembled, ensure the sealing of the pipeline. At the same time, a ground connection is adopted between each single unit and the pipe flange to avoid dust explosion caused by static sparks. Before trial operation of each stand-alone machine, check whether there are metal objects in the machine, and remove it if there is any. In addition, check whether the bolts are firm, the tightness of the belt, the reliability of the guard, and so on. The motor starts steadily. After five minutes of no-load operation, the operator should carefully observe the various instruments on the control cabinet and wait for the no-load current to stabilize before feeding.
What should I do if the bearing of the superfine grinder is overheated? When the bearing is poorly lubricated, damaged, or the main shaft is bent, the rotor is severely unbalanced, and the belt is too tight, the bearing will overheat. The bearings can be restored to normal state by adding or replacing lubricating oil, replacing bearings, spindles, balancing rotors, and adjusting belt tightness. The following reasons may cause the crusher to vibrate strongly: the hammers are installed incorrectly, the weight deviation of the corresponding two sets of hammers is too large, the bearing is damaged or the main shaft is bent, and the foot connecting screw is loose. If the hammers are arranged incorrectly, they should be rearranged according to the instructions; if the weight deviation of the corresponding two sets of hammers is too large, the weight should be balanced so that the weight difference does not exceed 5 grams; if the bearing is damaged or the spindle is bent, it should be replaced in time ; If the foot connecting screws are loose, they should be tightened.
