Plastic bottle flakes screening aims to grade and remove impurities to improve the purity and quality of recycled PET bottle flakes. Through screening, bottle flakes of different sizes and materials can be effectively separated, and impurities such as metal, dust, paper scraps, etc. can be removed to meet the needs of subsequent processing or reuse.

Bottle flakes process

The screening process of plastic bottle flakes usually includes the following steps:

Raw material pretreatment: Preliminary treatment of mixed plastic bottle flakes, such as breaking bags, breaking up, and uniform feeding.
Magnetic separation: Using magnetic separation technology removes magnetic metal impurities in bottle flakes.
Screening: Use a rotary vibrating screen or a linear vibrating screen to screen the bottle flakes and classify them according to size and shape.
Wind selection: Use wind screening technology to remove light substances in bottle flakes, such as paper scraps, plastic films, etc.
Fine sorting: Use photoelectric recognition, near-infrared detection, and other technologies to finely sort bottle flakes to remove impurities of the same color but different materials, such as PVC, PP, PE, etc.
Subsequent processing: The screened bottle flakes are cleaned, dried, packaged, etc. to meet the needs of reuse.

Screening Purpose

Grading and impurity removal: Classify plastic bottle flakes according to size, color, material, and other characteristics, and remove impurities.
Increase production: The processing capacity of the screening equipment must meet the production requirements of 500kg-6t/h.

Solutions

Solution 1: Rotary vibrating screen SY-1200

Suitable for preliminary screening of bottle flakes, the mesh aperture and vibration frequency can be adjusted as needed.
Equipped with a vibration reduction device to reduce the damage to the equipment itself caused by vibration.

Solution 2: Linear vibrating screen SYZ-550

It is suitable for continuous and efficient screening of bottle flakes with high screening efficiency.
Equipped with a feeding device to ensure that the bottle flakes enter the screening area evenly and continuously.

In summary, the plastic bottle flakes screening solution needs to comprehensively consider the raw material characteristics, screening requirements, equipment selection, automation, safety and environmental protection, etc. Through reasonable process flow and key equipment configuration, efficient, stable, and environmentally friendly screening effects can be achieved, providing high-quality PET bottle flakes for subsequent processing or reuse.
