What is the basis of waste sorting equipment?

Garbage sorting equipment can automatically sort waste, and the waste goes into plastic, metal, plastic and other materials, so how does waste sorting equipment separate out various wastes?
1. Magnetic separation; mainly used for classification of dry mineral resources. The principle of magnetic separation is to generate magnetic force and other mechanical forces (such as vehicle force, centrifugal force, friction force, medium resistance, etc.) after selecting other materials to enter the separation space.
2. Wind separation: The basic principle is that the air flow moves the lighter material upwards or along the horizontal direction to a farther place, while the heavier material settles because the rising air flow cannot support it, or moves along the horizontal direction due to shock Abandonment, short distance, the sedimentation law of various solid particles in dry air during the separation process of wind, air separation is mainly to collect paper and period materials and other visible components
3. Density classification: mainly classify objects according to their density, and classify garbage with different density values.
4.3D sorting: designed for the separation of inorganic particles in the garbage after coarse crushing, and designed the conveying equipment with separation function.
The machine utilizes the characteristics of crushed garbage materials, and the conveyor belt is designed on one side to have the function of bouncing up the material for conveying. At the same time, the inorganic particles or other hard particles are bouncing up, and the separated particles move in the opposite direction. The material is conveyed in one direction, so as to realize the separation of garbage. 3D sorting is mainly used to select components such as batteries, ceramics and masonry.
