The working principle of the environmentally-friendly screen divides the group of broken materials having different particle diameters into a plurality of layers by a single-layer or multi-layer screen, and the screens are evenly arranged to be sieved. Particles larger than the screen remain on the surface of the screen and are referred to as screens on the surface of the screen. Particles smaller than the screen pass through the screen and are referred to as screens under the surface of the screen. The actual screening process is that after a large number of different sizes and sizes of rough and scattering material enter the surface of the screen, only a portion of the particles are in contact with the surface of the screen. Due to the vibration of the screen box, the material layer on the screen is loose, so that large particles are present. The gap is further enlarged and small particles have the opportunity to pass through the gap and transfer to the lower layer or conveyor.

Since the small particle gap is small and the large particles cannot pass, the original disordered particle group is separated, i.e., the layer is layered according to the particle size, and the arrangement rule of the small particles under the coarse particles is formed. The fine particles reaching the surface of the sieve are sieved through a sieve, and coarse particles and fine particles are separated to complete the screening process. However, there is not enough separation, and during the screening process, a portion that is too small in size is usually left on the screen. When the fine particles are sieved, although the particles are smaller than the mesh, the ease of screening is different. Particles having similar environmentally friendly screen materials and mesh sizes are difficult to pass through the screen, and it is more difficult to pass through the gaps in the lower layer of the screen.

Compared with ordinary vibration equipment, the environmental protection screen has a short service life and a high maintenance rate. The environmentally friendly screen adopts the principle of low speed swing to ensure the service life of the equipment, reduce maintenance costs, reduce equipment noise and make the equipment safer. The vibrating mesh screen looks at the two-hand screen. Swinging the screen Swinging screen, also known as panning the screen and shaking the screen, is a device developed to solve the problem of irregular material blocking. This series of equipment borrows manual screening work to make the screen surface. The running track is a rocking motion on the left and right sides, so the problem of blocking the irregular material mesh can effectively improve the output and screening accuracy. The actuator must be turned by hand (or other means) before commissioning. The rotation should be flexible and there is no paper jam before the eco-screen machine is officially started.
