Reasons for and Solutions to the Severe Vibration of the 30B Crusher During Operation

The 30B Universal Pulverizer is composed of a material storage bin, mechanical pulverizer, induced draft fan, cyclone separator, vibration sieve, liquid nitrogen tank, etc. Utilizing liquid nitrogen as the cooling source, the material to be pulverized is cooled to achieve a脆and easily crushable state at low temperatures. It then enters the mechanical chamber where it is subjected to high-speed rotation of the impeller. Through a combination of repeated impacts, collisions, shearing, and friction between the material and the blades, disk, and between materials themselves, the desired pulverization effect is achieved.

Although the 30B crusher boasts numerous advantages during operation, many operators have reported experiencing intense vibrations during use. What's the reason behind this? Next, our editor will provide a brief analysis for you.

1. Error in Hammer Blade Installation During Maintenance: When replacing the hammer blades and flipping them over for reuse, all hammer blades inside the crushing machine must be flipped over simultaneously to prevent the rotor from becoming unbalanced, otherwise, severe vibration may occur during operation.

2. Some hammer blades are too tightly fastened, failing to dislodge during operation: After shutting down, manually turn and inspect them to find a way to make the blades rotate more freely.

3. For a difference in weight between the two sets of hammer blades exceeding 5 grams: The solution to address the weight discrepancy is to adjust the weight of the blades, ensuring the difference between the corresponding sets is less than 5 grams.

4. Exceeding Clearance or Damage of Bearings: When it is found that the bearing clearance exceeds the limit or is damaged, the general approach is to replace the bearing with a new one.

5. Main shaft bending deformation: The solution to this issue is to straighten or replace.

6. The bottom corner fixing nut is not tightened properly or loosens during operation: Tighten the nut to ensure stability during operation.

7. In the case of unbalanced weight on other parts of the rotor, a careful check and adjustment for balance is required. Additionally, if the traditional Chinese medicine ultra-fine powder machine is placed in an unbalanced location, it may experience strong vibrations. It is important to maintain the balance of the equipment.

The high efficiency of the 30B Crusher relies on careful operation by users in their daily use. Should the equipment encounter a fault that is not resolvable by the user, please remember not to handle it lightly. The correct approach is to seek professional assistance to avoid affecting future usage.
