Bouncing screen is a crucial step in the process of sorting and treating mixed waste from decoration and construction
By combining garbage bouncing screens and other crushing and sorting systems, decoration waste and mixed construction waste can be separated into four types of substances: building materials, combustibles, recyclables, and sand.Building materials (further processed into cushion layer, recycled aggregate)
Specific process:
Step 1: First, use a garbage bounce screen to roughly separate household waste into 2D sheet-like substances (such as plastic film, packaging bags, waste paper, etc.), 3D three-dimensional substances (such as bottles, cans, boxes, etc.), and small-sized substances (such as sand, organic matter, etc.):
Step 2: Use sensors to irradiate and identify by color (such as near-infrared), material (such as inert materials), visible light, laser, etc. Then, use compressed space for spray separation to finely sort the above three types of substances.
By combining this "golden combination" once or multiple times, it is possible to achieve precise separation of mixed household waste into PP film, PE/PP/PS, PET bottles, and mixed paper RDF、 Organic matter and other purposes.
working principle
The rotating sieve plate of the garbage bounce screen will sort the garbage onto or off the screen according to its different appearance, shape, and characteristics. The garbage bounce screen classifies garbage according to its different characteristics, and can separate plastic garbage from cardboard, waste paper, and film. It is also suitable for separating light substances such as films from cylindrical garbage bottles and cans. Depending on the speed of movement, 3D shaped garbage will be bounced off the screen, while 2D shaped garbage such as film and paper will be bounced onto the screen, achieving the goal of garbage classification. By adjusting the angle of the sieve plate, the sorting accuracy can be adjusted. The garbage bounce screen is usually installed at the starting machine of the automatic sorting line in the garbage recycling system to improve the types of recyclable waste and maximize the separation efficiency of the back-end separator.
