Claw crusher is widely used by users due to its wide range of uses, high processing quality, and high efficiency. However, how to use it is very particular. 1. Correct operation Use a comprehensive inspection of the machine before start-up to confirm that all parts are in good condition. Can be booted. After starting up, it should be idling for 1-2min before confirming that there is no abnormal phenomenon before feeding. The feed should be uniform and pay attention to the amount of feed adjustment. When processing grains such as corn, the amount of feed is controlled with a regulating gate to make it evenly fed. When processing soybean cake, potato vines and other feed, in order to facilitate the comminution, the bean cake must be broken first, and its maximum diameter is within 40mm; the potato vines should be chopped first, and the length should be about 150mm; if crushing fresh potatoes, it must be preceded by Dicing and adding proper amount of water, at the same time, need to feed evenly to prevent the crusher from overloading and affecting the crushing quality. When the powder bag is used to make powder, when the powder in the bag reaches 1/3, the powder should be taken immediately to prevent the temperature from rising and the output from falling. After taking the powder, the bag should be vibrated to increase the air permeability. 2. Ensure that the safety production transmission should be provided with protective barriers. Operators should stand on the side of feeding, and should not stand on both ends of the shredder. The cuffs of the clothes should be tied well and long hair should be put into the work cap. Before entering the hopper, the materials should be cleaned of nails, stones and other debris, so as not to damage the machine. During the feeding process, if the material inlet is blocked, it must not be cleaned by hand. It should be stopped to clear the plug. The use of motor power should be cut off the power before troubleshooting. Fireworks are prohibited on the job site, and it is forbidden to increase output by increasing the speed. 3. Strengthen the maintenance When the machine is running, the bearing temperature can't exceed 40 degrees. If the bearing temperature continues to increase under normal working conditions, check the machine immediately to find out the cause and troubleshoot. After each operation, check whether the bolts of each department are loose, check whether the seal at the joint is good, check whether the rotor rotates flexibly, whether there is collision and noise, and check the abrasion of the inner teeth and the screen. If it is serious, it should be replaced in time. In addition, lubricants should be regularly filled with lubricant.
