Analysis of common problems in plastic milling

In recent years, plastic milling has gradually become a new material processing method, which can use waste plastics, environmental protection and energy saving, and also has the advantages of high efficiency, low cost and easy operation. However, in the process of plastic grinding processing, there will be some common problems, this paper will be combined with the actual production situation, the common problems of plastic grinding processing are analyzed.

Problem 1: The crushing effect is not good

In the plastic milling process, the crusher is one of the most commonly used equipment, and its crushing effect directly affects the subsequent operation progress. The reasons for the poor crushing effect may have the following aspects:

1. Crusher tool wear: In the process of use, the tool will go through long-term friction and wear, resulting in a decline in its cutting ability, the need to replace the tool in time.

2, the material is too large: if the material is too large, it will lead to an increase in the load of the crusher, the crushing effect is not good, the need for material screening or reduce the number of materials into the crusher.

3. Crusher equipment failure: If the crusher equipment is damaged and faulty, the material can not be broken in time, resulting in poor crushing effect, and the need for timely maintenance or replacement of equipment.

Problem 2: Overheating occurs during the crushing process

In the processing of plastic milling, high temperature is a common problem, if it is not handled in time, it may lead to equipment burning or even explosion. The reasons for overheating in the crushing process are mainly as follows:

1. Improper maintenance of equipment: If the equipment is not maintained for a long time, it will bring a very big risk to the equipment, resulting in internal dirt of the mill, blockage of the flying knife, overheating of the bearing and other failures.

2. Too high water content of the material: In the case of too high water content of the material, it will cause the internal heat of the crusher to be too high, resulting in overheating phenomenon, and it is necessary to carry out material treatment or reduce the number of materials entering the crusher.

3.Crushing process is too fast: if the operator will speed up the crushing process, it may lead to the final crushing quality is poor, but also produce too much heat, resulting in overheating equipment, need to adjust the speed and time properly.

Problem 3: Excessive dust pollution

In the processing of plastic milling, dust pollution is a very serious problem, if not taken timely measures to clean up, it may lead to the deterioration of working environment health conditions, but also have an impact on health. The reasons for excessive dust pollution are mainly as follows:

1. Poor equipment maintenance: if the equipment is not maintained for a long time, it will lead to the internal cleaning of the crusher is not timely, and the accumulation of dust is large, affecting environmental health.

2. Unqualified materials: If the material contains too many impurities or foreign bodies, it will produce dust pollution during the crushing process, affecting environmental health.

3. Improper operation of workers: If the operator does not wear protective measures such as masks, it will also cause a certain degree of pollution to the environment.

The above are three common problems in the processing of plastic grinding powder, which need to be solved in time to ensure the health of the production environment and the improvement of work efficiency.
