Bounce Screening Machine

Bouncing Screen for Waste Sorting, also known as a bouncing screen, is a new type of screening machine specifically developed for the sorting and processing of waste. Its principle relies on the differences in size, density, and shape of various components in the sorting material. As the material moves or collides on an inclined surface, it generates different velocities and trajectories, thereby achieving separation. It is commonly used in industries such as sorting municipal waste, pre-selecting construction waste, post-compression kitchen waste, and paper recycling.

The Bouncing Screen is the core component of the Bouncing Sorting Machine. It provides the inclined surface for collision and bouncing, allowing lightweight waste such as plastic bags to be separated.

The garbage bouncing screen is a shutdown equipment designed with separation function for inorganic particles in garbage after coarse crushing. It utilizes the characteristics of garbage materials after crushing, and separates them based on their different specific gravities when the garbage reaches a certain particle size. The garbage bouncing screening machine is designed with a bouncing function, which, while conveying materials on one side, bounces and separates inorganic particles or other hard particles from the material flow. The separated particles move in the opposite direction of the material flow, thus achieving the purpose of separation.

By combining the garbage bouncing screen with other crushing and sorting systems, it is possible to separate mixed municipal waste into four categories: building materials, combustibles, recyclables, and sand.

The specific process involves:

1. Coarse separation of municipal waste using the bouncing screen, dividing it into 2D materials (such as plastic film, packaging bags, waste paper, etc.), 3D materials (such as bottles, cans, boxes, etc.), and fine particles (such as sand, organic matter, etc.).
2. Precision sorting using sensors based on color (e.g., near-infrared), material (e.g., inert materials), visible light, lasers, etc., followed by separation through compressed air blowing.
   Through this process, mixed municipal waste can be effectively separated into PP film, PE/PP/PS, PET bottles, mixed paper, RDF, organic matter, and more.

The working principle involves the rotation of the screen plate, which sorts the garbage into two categories based on different appearances and characteristics. This screen is capable of separating plastic waste from paperboard, waste paper, and film, as well as separating lightweight materials like film from cylindrical garbage bottles and cans. Depending on their different movement speeds, 3D-shaped garbage is bounced below the screen, while 2D-shaped garbage such as film and paper is bounced above the screen, achieving the purpose of garbage classification. The angle of the screen plate can be adjusted to regulate the sorting precision. The garbage bouncing screen is typically installed at the beginning of the automatic sorting line of a waste recycling system to enhance the efficiency of the subsequent separators.

Features and Advantages:

1. Large screen plate size, high processing capacity.
2. Stable and durable crankshaft.
3. Fully enclosed to prevent dust.
4. Removable screen plate for easy replacement.
5. Adjustable screen plate angle for flexible adjustment of sorting precision.

Application Range:

1. Sorting combustible waste, recyclable waste, and backfill waste.
2. Separating glass bottles and ceramics.
3. Separating plastic packaging from film or waste paper.
4. Can remove inert impurities up to 10mm in size.
   Separated Materials:
   2D materials: Film, paper, cardboard, textiles, and fiber materials.
   Crushed materials: Sorted based on the size and diameter of the paddle holes.
   3D materials: Plastic containers, bottles, stones, wood, cans, and metal materials.
