Plastic grinding

Plastic crushing processing usually refers to the processing of waste plastic products into a powder state for subsequent reprocessing and utilization. Plastic grinding processing has the advantages of simple, low cost and reuse of waste plastics, which is an environmentally friendly and economic processing method. This paper will introduce the selection of raw materials, processing process, equipment and its advantages.

First, raw material selection

The raw materials for plastic crushing processing are usually waste plastic products, including bottle caps, plastic bags, plastic pipes, plastic wrap, PE, PP and other different types of plastic products. For different types of plastics, the selection of grinding processing methods are also different. For example, high-density polyethylene can be processed by cutting, while polypropylene usually needs to be ground.

Second, the processing process

The plastic crushing process usually includes the following steps:

1. Remove debris that affects plastic crushing. Such as removing wood chips, metals and other contaminants.

2. Select the appropriate crushing equipment. Commonly used grinding equipment are blade type mill, pellet machine and mill.

3. Perform the initial crushing. The plastic products are roughly processed by cutting, crushing and other ways to break them into small pieces.

4. Refine. The small pieces of plastic products are broken again, ground and other ways to fine treatment, so that it can reach the required powder state.

5. Sieve. The powder is screened, the coarse particles are removed, so that it reaches the required fineness, and the fineness can be controlled by different screens.

6. Perform quality inspection. Conduct quality inspection of the crushed plastic powder to ensure that it meets the requirements.

7. Packaging and shipping. The standard plastic powder is packaged for easy transportation and storage.

Third, equipment and its advantages

Commonly used plastic grinding processing equipment are blade type grinder, pellet machine, grinding machine and so on. Blade mill is a high-speed rotating blade and fixed blade grinding each other, cutting raw materials into uniform particle size equipment. Pellet machine and mill is a kind of equipment that grinds and breaks the material through extrusion and friction, so that it reaches the required particle size and fineness.

Plastic grinding has the following advantages:

1. Be environmentally friendly. The reuse of waste plastics reduces the pollution to the environment.

2. The economy. Plastic crushing processing equipment is low-cost, simple to operate, and can transform plastic waste into useful plastic powder, saving resources.

3. Reuse. The crushed plastic powder can be processed again, and the plastic powder is added to the production of new plastic products to achieve the effect of reducing costs and improving product performance.

4. Controllable. With different processing methods and equipment, the particle size and fineness of the obtained plastic powder can be controlled, which is convenient for subsequent processing and utilization.

In short, plastic crushing processing is an environmentally friendly and economic processing method, which can effectively use plastic waste and has high application value.
