Common faults and troubleshooting of superfine pulverizer
The ultra-fine pulverizer has strong wear and corrosion resistance, and is suitable for processing high-grade and corrosive materials. The machine adopts the impact crushing method. After entering the crushing chamber, the materials are impacted by six moving hammers rotating at high speed, and are crushed by the collision between the gear ring and the materials. With the help of air flow, the crushed materials enter the powder bag through the screen hole without leaving residue. It has the advantages of high efficiency, low noise, reliable working performance and product quality, safe operation, drug hygiene and low loss.
The ultra-fine pulverizer generally adopts the motor to directly connect the pulverizing device, which is simple and easy to maintain. However, if the two cannot be well connected in the assembly process, it will cause the overall vibration of V.
(1) The motor rotor is not concentric with the rotor of the ultra-fine pulverizer. The position of the motor can be moved left and right, or a pad can be added under the motor foot to adjust the concentricity of the two rotors.
(2) The rotor of ultra-fine pulverizer is not concentric. The reason is that the two bearing surfaces of the palm rotor shaft are not in the same plane. Copper sheet can be padded on the bottom surface of the supporting bearing seat, or an adjustable wedge iron can be added at the bottom of the bearing to ensure that the two shaft heads are concentric.
(3) The crushing chamber vibrates greatly. The reason is that the connection between the coupling and the rotor is not concentric or the quality of the flat hammer inside the rotor is uneven. Corresponding methods can be adopted according to different types of couplings to complete the connection between the coupling and the motor: when the quality of the hammer pieces is uneven, each group of hammer pieces must be re selected to make the symmetrical hammer pieces, so that the error of the symmetrical hammer pieces is less than 5g.
(4) The original balance was destroyed. Dynamic balance test shall be conducted after motor repair to ensure the overall matching balance.
(5) If the foundation bolts of the ultra micro crusher system are loose or the foundation is not firm, the foundation bolts shall be tightened evenly during installation or maintenance. A damping device shall be installed between the foundation and the crusher to reduce vibration.
(6) The hammer blade is broken or crushed, and there are hard sundries in the room. These will cause the rotor rotation imbalance and cause the vibration of the whole machine. Therefore, it is necessary to regularly check the hammer pieces with serious wear. Replace symmetrically during replacement; In case of abnormal sound during the operation of the crusher, stop the machine immediately for inspection, find out the cause and deal with it in time.
(7) The connection between the pulverizer system and other equipment is inconsistent. For example, improper connection of feed pipe and discharge pipe will cause vibration and noise. Therefore, these connecting parts should not adopt hard connection, and it is better to adopt soft connection.
