There is abnormal sound inside the super fine grinder, the parts inside the grinder are damaged or fall off, or hard objects such as stones and iron blocks enter the machine, which will cause abnormal sound, stop the machine immediately for inspection, replace the damaged parts or take out the hard objects . Low production efficiency: Insufficient motor power, improper pulley preparation, belt slippage, severe hammer wear, uneven feeding or high moisture content of raw materials are the main reasons for low production efficiency. If the above situation occurs, corresponding measures can be taken to solve it, or replace the motor or pulley to increase the speed, but not exceed the rated operating speed; or adjust the belt tightness, or replace the belt, or replace the hammer. During the operation, the feeding should be uniform, and a small amount should be added quickly to keep it continuous and uniform; the raw materials that are too wet should be dried and then pulverized.
For the operation and use of the super fine grinder, after opening the box, first carefully check whether there is any damage in the equipment during transportation, then put the electric control devices of the high-speed machine and auxiliary machines in place, and then connect the pipelines of the main and auxiliary machines. When the flange is assembled, the seal must be coated with "Anchor 609" liquid sealant to ensure the tightness of the pipeline. At the same time, each stand-alone unit and pipeline flanges are connected with grounding wires and grounded to avoid dust explosion caused by static sparks. Before the trial operation of each stand-alone machine, it is necessary to check whether there are metal objects in the machine, and remove them if any. Whether the bolt is firm, the tightness of the belt, the reliability of the protective cover and so on. Start each motor steadily in the following order. After five minutes of empty running, the operator should carefully observe the various instruments on the control cabinet, and feed materials only after the no-load current is stable. After feeding, the current is not allowed to exceed the rated value of 32.6A, otherwise the feeding amount should be reduced to ensure that the discharge motor can work regularly during normal operation.
What to do if the super fine grinder bearing 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 bearing can be restored to normal state by adding and replacing lubricating oil, replacing bearings and main shafts, balancing the rotor, and adjusting the tightness of the belt. The pulverizer vibrates strongly. The following reasons may cause the pulverizer to vibrate strongly. The installation and arrangement of the hammer pieces are wrong. The weight deviation of the corresponding two sets of hammer pieces is too large. If the hammers are arranged incorrectly, they should be rearranged according to the instructions; if the weight deviation of the corresponding two groups 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 main shaft is bent, it should be replaced in time ; If the foot connection screws are loose, tighten them.
