How to treat the common faults of pulverizer

The vibration pulverizer is generally used motor directly connected to the grinding device, this connection is simple and easy to repair. But Guangdong Rich Packing Machinery Co. Ltd. in the assembly process concluded that if both are not well connected, it will cause the whole vibration mill. So, summed up the seven common problems, hoping to help customers more simple to solve the problem.

(1) The motor rotor is not concentric with the rotor of the pulverizerl. You can move left and right position of the motor, or on foot pad is added below the motor, to adjust the concentricity of the two rotor.

(2) When the pulverizer rotor is not concentric. The reason is that two supporting surfaces of the supporting rotor shaft are not in the same plane. In the bearing seat bottom surface of the copper pad, or increase the wedge adjustable bearing in the bottom, by 2 concentric shaft guarantee.

(3) Part of the crushing chamber vibration. The reason is that the coupling of the coupling and the rotor is not concentric or the quality of the flat hammer in the rotor is not uniform. You can take the appropriate method to adjust the coupling with the motor according to the different types of couplings: when the hammer of uneven quality, must be re matching each hammer, the hammer is symmetrical, the hammer symmetry error less than 5G.

(4) When the original balance is destroyed. You can take , the dynamic balance test to ensure the overall balance of the machine

after the motor is repaired.

(5) The pulverizer system of anchor bolts loose or solid foundation, in the installation or maintenance, evenly fastening bolt, between foundation and mills, to reduce the vibration damping device.

(6) The hammer broken or crushed indoor hard debris. These can cause the unbalance of the rotor rotation, and cause the vibration of the whole machine. Therefore, to check regularly, for wear and tear of the hammer. In the replacement, to replace the symmetry; the operation of the mill appears abnormal sound, to immediately stop the inspection, to find the reasons for the timely processing.

(7) Connected pulverizer system with other devices do not coincide. For example, feeding tube, discharge tube, such as improper connection, will cause vibration and sound. Therefore, the connection part, should not use hard connection, it is better to use soft connection.

With the long time the use of the machine there is always small problems, but can not solve it will seriously affect the life of the machine, the customers to meet what problem can contact us directly in the our pulverizer.
