rules for feed mills read
Buying a good feed shredder, if not used properly, 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 of the two should be matched, that is, the diesel engine power is slightly larger than the pulverizer power, and both The pulley grooves are the same, 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, it must be tightened.
3. Check if the belt tightness is appropriate and whether the motor shaft and the pulverizer 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 will be too low, which will affect the working efficiency.
6. After the pulverizing table is started, it will be idling for 2-3 minutes. After no abnormal phenomenon, it will be fed again.
7, at work should pay attention to the operation of the pulverizer at all times, the feeding should be even, to prevent blocking the car, do not 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 inspected carefully to avoid accidents such as copper, iron, stones and other hard objects entering the crushing room.
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.
Feed crusher common mechanical failure treatment method
The pulverizer is one of the main equipments for the feed mill to produce feed. The reliability of the pulverizer operation is directly related to the production efficiency and the normal operation of the subsequent processes. Therefore, the maintenance and operation personnel learn to analyze and deal with the common failures of the pulverizer system, and in the short term. It is important to exclude it and resume production as soon as possible. The pulverizer system mainly includes a pulverizer and an electric motor. Corresponding faults can be classified into mechanical faults and electrical faults. The following is an analysis of the faults in the mechanical failure and vibration, bearing heating and pulverizer blockage.
1. The vibration pulverizer generally uses a motor directly connected to the pulverizing device. This connection method is simple and easy to maintain. However, if the two are not well connected during the assembly process, the overall vibration of the pulverizer will be caused.
(1) The rotor of the motor is not concentric with the rotor of the pulverizer. You can move the position of the motor left or right, or pad the bottom of the motor to adjust the concentricity of the two rotors.
(2) The pulverizer rotor is not concentric. The reason is that the two bearing faces of the rotor shaft are not in the same plane. The copper can be padded on the bottom of the bearing housing, or an adjustable wedge iron can be added to the bottom of the bearing to ensure that the two shaft heads are concentric.
(3) The vibration of the crushing chamber is large. The reason is that the coupling of the coupling and the rotor is not uniform or the mass of the flat hammer inside the rotor is not uniform.
(4) The original balance was destroyed. After the motor is repaired, a dynamic balance test is required to ensure the overall balance.
(5) The anchor bolts of the pulverizer system are loose or the foundation is not strong. When installing or repairing, the anchor bolts should be evenly tightened. Between the foundation of the shovel and the pulverizer, shock absorbing devices should be installed to reduce vibration. .
