Plastic granules square swing screen

Plastic granules square swing screen is a device specially used for screening plastic granules. It is suitable for screening, grading and removing impurities of plastic granules of different specifications. It uses the principle of artificial screening to make the material move horizontally in a circular motion and throw forward on the screen surface, improve the screening accuracy and processing capacity, and is widely used in plastics, chemicals, food, new materials and other industries.

What is the working principle of plastic granules square swing screen?

Plastic granules square swing screen simulates the movement of artificial screening to make the material move in three dimensions on the screen surface, thereby achieving high-precision screening. Its gentle swinging motion reduces the damage of plastic granules and is suitable for screening various plastic granules.

Types of plastic granules square swing screen

1. Single-layer plastic granules square swing screen

① Application scenario: Suitable for occasions with simple granules screening requirements, mainly used for screening plastic granules of a single specification, commonly seen in the initial screening process.

② Applicable materials: coarse screening of plastic granules (such as PP, PE, etc.).

2. Double-layer plastic granules square swing screen

① Application scenario: Suitable for screening requirements with a variety of granules specifications, suitable for medium-sized production scale, and can screen two types of granules size materials at the same time.

② Applicable materials: grading and screening of plastic granules (such as PVC, ABS, etc.).

3. Three-layer plastic granules square swing screen

① Application scenario: Suitable for production processes that require multi-level grading or fine screening, suitable for large-scale production lines or occasions that require high-precision screening.

② Applicable materials: fine grading and multi-level separation of plastic granules (such as PET, nylon, PE, etc.).

What are the advantages of plastic granules square swing screen?

1. Dealing with irregular plastic granules blocking holes and materials: Crushed plastics contain long strips and flaky impurities, which are easy to get stuck in square or round sieve holes. The trajectory of plastic granules square swing screen is a compound parabola, and the granules are subject to multi-dimensional acceleration, which promotes screening.

2. Solving the problem of low efficiency of multi-size classification of plastic granules: The single layer of plastic granules square swing screen can be equipped with up to 5 levels of screens to achieve multiple screens in one machine.

3. Dealing with the problem of high crushing rate of brittle plastic granules: Engineering plastics are easy to break in high-frequency vibration. Using dual motors in reverse synchronous drive, the vibration frequency is reduced to 800rpm, and the amplitude is increased to 8mm to reduce granules collision.

4. Static adsorption causes screen blockage: Plastic granules are prone to generate static electricity due to friction, and fine powder adheres to the screen, reducing the screening rate. Plastic granules square swing screen uses conductive materials or adds carbon powder coating to eliminate static electricity accumulation.

Application of plastic granules square swing screen

1. Plastic granulation production line: Plastic granules may have problems such as uneven particle size, dust or impurities. Plastic granules square swing screen is used to accurately screen these plastic granules and remove unqualified granules.

2. Plastic recycling: After the recycled waste plastics are pre-treated by crushing, cleaning, etc., they need to be screened to remove impurities and plastics of different particle sizes. Plastic granules square swing screen can efficiently classify recycled plastics.

3. Plastic modification production: Additives are mixed with plastic raw materials and granulated through processes such as extrusion. Plastic granules square swing screen is used to screen the modified plastic granules and remove agglomerated or unqualified granules.

4. Plastic powder screening: Plastic powder is produced during plastic processing, and these powders can be used to produce certain special products. Plastic granules square swing screen is used to screen plastic powder to meet different mesh requirements.

Plastic granules square swing screen is widely used in the production, recycling, modification and other links of plastic granules. It can improve product quality and production efficiency, and is an indispensable equipment in the plastic industry.
