Buying a good feed shredder, if not used correctly, will not only shorten the service life of the feed mill, but also affect the work efficiency, resulting in half the effort. 1. The long-term operation of the pulverizer should be fixed on the cement foundation. If the working place is changed frequently, the pulverizer and the motor should be installed on the base made of angle iron. If the pulverizer is powered by diesel, the power should be matched, that is, the diesel power is slightly larger than the pulverizer power, and both The pulley grooves are identical, and the outer end faces of the pulleys are on the same plane. 2. After the pulverizer is installed, check the fastening condition of each fastener. If it is loose, tighten it. 3. Check that the belt tightness is appropriate and that the motor shaft and the shredder shaft are parallel. 4. Before starting the pulverizer, first turn the rotor by hand to check whether the teeth, hammer and rotor are running flexibly and reliably. There is no collision in the shell. The rotation direction of the rotor is consistent with the direction indicated by the arrow on the machine. Motor and powder Whether the machine lubrication is good. 5. Do not change the pulleys casually, in case the rotation speed is too high, the explosion chamber will explode, or the rotation speed is too low, which will affect the working efficiency. 6. After the pulverization table is started, it will be idling for 2 minutes to 3 minutes. After no abnormal phenomenon, it will be fed again. 7. Attention should be paid to the operation of the pulverizer at all times during work, and the feeding should be uniform to prevent the stagnation of the car and not to overload the machine for a long time. If vibration, noise, high temperature of the bearing and the body, and external spraying are found, stop the test immediately and continue working after troubleshooting. 8. The crushed materials should be carefully inspected to prevent accidents such as copper, iron, stones and other hard objects entering the crushing chamber. 9. The operator should not wear gloves. When feeding, stand on the side of the crusher to prevent rebound debris from injuring the face. 10. When clogging, it is strictly forbidden to forcibly feed or tow the feed by hand or wooden stick. In addition to the correct use of the feed mill, the daily crushing and maintenance of the feed mill should be carried out to prevent the occurrence of the breaker failure and prolong its service life. 1. Repair and replacement of the screen. The screen is made of sheet steel or iron. When the screen is worn or broken by foreign matter, if the damage is not large, it can be repaired by riveting or soldering; if the area is damaged, the new screen should be replaced. When installing the screen, the burr side of the screen hole should face inward, the glossy side should be facing outward, and the screen and screen frame should be tightly attached. When the ring screen is installed, the lap of the lap should be in the direction of rotation to prevent the material from getting stuck at the lap joint. 2. Lubrication and replacement of bearings. The bearings should be cleaned after every 300 hours of operation of the mill. If the bearing is oil lubricated, it is advisable to fill the bearing housing clearance by 1/3 when adding new oil, and the maximum is not more than 1/2. Just tighten the capped oil cup cover a little before operation. When the crusher bearing is seriously worn or damaged, it should be replaced in time, and pay attention to strengthen lubrication; the crusher using tapered roller bearing should pay attention to check the axial spacing of the bearing to keep it 0.2 mm ~ 0.4 mm, if there is discomfort, It can be adjusted by increasing or decreasing the paper pad at the bearing cover. 3. Replacement of the claws and the hammer. Among the pulverized parts, the pulverizing claws and the hammer pieces are the wearing parts in the feed pulverizer, and are also the main components affecting the pulverizing quality and productivity. The pulverizing claws and the hammer pieces should be replaced in time after being worn. When the jaw crusher replaces the claws, the disc should be pulled out first. Before pulling out, first open the round nut lock piece on the back of the disc, use a hook wrench to unscrew the round nut, and then pull the disc out with a special puller. In order to ensure the balance of the rotor operation, it is necessary to pay attention to the complete set of replacement when changing the teeth. After the replacement, static balance test should be done to make the crusher work stably. Be sure to tighten the nut when assembling the jaws, and be careful not to miss the spring washer. The qualified parts should be selected when changing the teeth, and the weight difference of the single claws should be no more than 1.0. The hammer of the hammer mill is symmetrical. When the sharp corner of the hammer is blunt, it can be used on the reverse side. If both ends of the hammer are worn, the head should be used. When adjusting or adjusting the head, all the hammers should be carried out at the same time. After the four corners of the hammer are worn, they should be replaced completely, and the weight difference of each group of hammers should not be too large; spindle, disc, positioning sleeve, pin shaft, hammer assembly After the good, a static balance test should be done to maintain the balance of the rotor and prevent the unit from vibrating. In addition, the pin of the fixed hammer and the circular hole of the mounting pin are worn out, the pin will be gradually ground, and the round hole will be gradually enlarged. When the pin diameter is smaller than the original size, the diameter of the hole is larger than the original size. Should be repaired or replaced in time. Ji Nong
