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 achieve a brittle and easily crushed state at low temperatures. After entering the mechanical chamber, it rotates at high speed through an impeller, and under the combined effects of repeated impact, collision, shear, friction, and other factors between the material and the blades, toothed discs, and materials, the crushing effect is achieved.

　　Although there are many advantages of the 30B crusher in use, many operators will feedback that the equipment will experience strong vibration during the operation process. 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 replaced and turned around for use, in order to prevent the weight of the rotor from losing balance, all hammer pieces in the crusher must be replaced and turned around together, otherwise strong vibration may occur during operation.

　　2. Some hammer blades are too tightly stuck and did not swing during operation: they can be manually rotated and observed after shutdown to find a way to make the hammer blades rotate flexibly.

　　3. The difference in weight between the corresponding two sets of hammer pieces exceeds 5 grams: For the problem of weight difference, the solution is to adjust the weight of the hammer pieces so that the difference in weight between the corresponding 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 position, strong vibration may also occur, and the equipment should be kept in a balanced state.

　　The efficient operation of the 30B crusher cannot be separated from the careful operation of the user in daily use. When the equipment malfunctions, if it is not something that the user can solve on their own, please remember not to handle it easily. The correct way is to seek professional help to avoid affecting later use.
