Peanut grading machine is one of the commonly used equipments in peanut processing, and its main function is to sort and classify peanuts. However, many users may encounter the problem that the working noise of the equipment suddenly increases during use. The following will analyze the possible reasons for this phenomenon and provide corresponding solutions.

Possible causes of increased noise in peanut grading machines:

1. The bearing is worn or damaged.
The bearing of peanut grading machine is prone to wear or loosen in long-term operation, which leads to abnormal noise during operation.
2. Parts are loose.
After the equipment is used for a long time, some parts may become loose due to vibration, resulting in abnormal friction or collision sound inside the machine body.
3. Foreign matter enters the equipment.
If the peanut grading machine is mixed with hard foreign materials such as stones and metal pieces, it may rub against the parts inside the machine, resulting in greater noise.
4. Insufficient lubrication.
The transmission parts of peanut grading machine need to be lubricated regularly. If the lubricating oil is insufficient or has not been replaced for a long time, it may lead to an increase in friction between components, which may lead to a greater noise.
5. Equipment aging or overload operation.
Long-term high-intensity operation may lead to equipment aging or overload operation, thus causing noise problems.

The solution to increase the noise of peanut grading machine:

1. Check and replace the bearing.
If the bearing is found to be worn or damaged, replace it with a new bearing in time and ensure that it is installed firmly.
2. Fasten loose parts.
Regularly check whether the bolts and connectors of the equipment are loose. If it is loose, it should be fastened immediately to avoid further damage to the equipment.
3. Clean up foreign bodies.
After stopping the machine, check whether there are foreign objects in the equipment, and clean them up immediately if found. At the same time, the screening of raw materials should be strengthened to avoid hard impurities from entering the equipment.
4. Regular lubrication and maintenance.
Add or replace lubricating oil regularly according to the requirements of the equipment manual to ensure the smooth operation of the transmission parts.
5. Rational use of equipment.
Avoid long-term overload operation, and regularly overhaul and maintain the equipment to prolong the service life and reduce the probability of noise problems.

There are many reasons for the increasing noise of peanut grading machine, so users need to investigate and deal with it according to the specific situation. Users should pay attention to the maintenance of equipment in daily use to ensure its long-term stable and efficient operation.
