The 30B universal crusher is composed of a silo, a mechanical crusher, an induced draft fan, a cyclone, a vibrating screen, a liquid nitrogen tank, and other components. It uses liquid nitrogen as the cold source, and the crushed material is cooled to a brittle and easily crushed state at low temperatures. After entering the mechanical chamber, it rotates at high speed through an impeller, and the material repeatedly impacts, collides, shears, rubs, and other comprehensive effects between the material and the blades, teeth, and material to material, achieving the crushing effect.

　　Although the 30B crusher has many advantages in use, many operators will give feedback on the strong vibration of the equipment during operation. What is the reason for this? Next, the editor will provide a brief analysis for everyone.

　　1. Installation error of hammer during maintenance and assembly: When the hammer is changed and turned around during use, in order to prevent the weight of the rotor from losing balance, all hammer pieces in the crusher must be changed and turned around together, otherwise strong vibration will occur during operation.

　　2. Some hammer pieces are stuck too tightly and do not shake off during operation: you can turn and observe by hand after stopping the machine, and find a way to make the hammer pieces rotate flexibly.

　　3. The difference in weight between two sets of hammer pieces exceeds 5 grams: To address the issue of weight difference, the solution is to adjust the weight of the hammer pieces so that the difference in weight between the two sets is less than 5 grams.

　　4. Bearing clearance exceeds the limit or is damaged: When the bearing clearance exceeds the limit or is damaged, the method of replacing the bearing with a new one is generally adopted.

　　5. The solution to spindle bending deformation is to straighten or replace it.

　　6. Bottom corner fixing nut not fixed tightly or loose during operation: Tighten the nut to maintain stability during operation.

　　7. The weight of other parts on the rotor is unbalanced, and it is necessary to carefully check and adjust the balance separately. In addition, if the traditional Chinese medicine ultrafine grinder is placed in an unbalanced area, strong vibration may also occur, and the equipment should be kept in a balanced state.

　　The high efficiency of the 30B crusher cannot be achieved without careful operation by the user during daily use. When the equipment malfunctions, if it is not something that the user can solve on their own, remember not to handle it easily. The correct way is to seek professional help to avoid affecting later use.
