What should we pay attention to in plastic milling processing technology?

Plastic grinding technology is a method to reuse waste plastic materials, which can effectively reduce the amount of plastic waste and has great significance for environmental protection. However, in the process of plastic grinding processing, some important issues need to be paid attention to to ensure the quality and production efficiency of the grinding product. Here is to introduce the points that plastic grinding processing technology should pay attention to.

1. Treatment of plastic before grinding

Before plastic milling, plastic waste needs to be adequately pre-treated. This step is very important and directly related to the quality and efficiency of the subsequent grinding process. First of all, it is necessary to classify waste plastic materials to remove materials that are easily deteriorated or have been contaminated. In addition, it is also necessary to wash and dry the waste material to ensure that its surface is clean and free of oil, and the water content is low before it can enter the next step of treatment.

2. Select the appropriate grinding equipment

It is also important to choose the appropriate grinding equipment. The processing capacity and working principle of different types and specifications of plastic grinding equipment are different, and choosing the right equipment can improve grinding efficiency and finished product quality. It is necessary to select the appropriate grinding equipment according to the specific material properties and processing requirements to ensure that the grinding process can be uniform and efficient.

3. Control the grinding temperature

In the processing of plastic grinding, it is necessary to pay attention to controlling the grinding temperature. Too high temperature will lead to the alienation and denaturation of plastic materials, which will affect the quality and performance of the finished mill. Therefore, before grinding processing, it is necessary to adjust the temperature and feeding speed of the grinding equipment, and constantly adjust according to the actual situation to ensure that the temperature is within the appropriate range, and it is also necessary to real-time monitor the temperature in the grinding processing, and timely adjust the parameters and processing methods of the grinding equipment.

4. Pay attention to granularity and quality control

In the processing of plastic grinding, it is necessary to pay attention to the control of particle size and quality. The particle size and quality of plastic grinding powder produced by different types of grinding equipment have significant differences, and equipment selection and adjustment need to be made according to specific requirements. In addition, it is also necessary to classify and control the finished products in the grinding process to ensure the stability and consistency of the finished product quality.

5. Control of plastic ratio and reuse times

In the plastic grinding processing, it is also necessary to control the ratio of plastics and the number of reuse. The physical and chemical properties of different types of plastic materials are different, and scientific proportions are needed to ensure the stability and performance of the finished product. In addition, the number of reuse also needs to be controlled, and excessive reuse times will have a negative impact on the quality and performance of the finished mill.

In short, plastic grinding processing technology needs attention and control in many aspects to ensure the optimization of the final grinding product quality, production efficiency and processing costs. Therefore, it is necessary to learn and master the processing technology of plastic grinding powder.
