First, the pilot electromagnetic vibrating screen divides the crushed material components with different particle sizes into multiple layers through single-layer or multi-layer uniform holes, and divides them into several different levels to form a screen.

First, the pilot electromagnetic vibrating screen divides the crushed material components with different particle sizes into multiple layers through single-layer or multi-layer uniform holes, and divides them into several different levels to form a screen. Particles larger than the mesh remain on the surface of the sieve and are called sieves on the surface of the sieve, and particles smaller than the mesh pass through the mesh and are called sieves under the surface of the sieve. The actual screening process is: after a large number of coarse and scattering materials of different sizes and sizes enter the screen surface, only a part of the particles contact the screen surface. Due to the vibration of the screen box, the material layer on the screen is loosened, 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, the large particles cannot pass through, so the original disordered particle group is separated, that is, 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 sieve surface are sieved through a sieve, and then coarse particles and fine particles are separated to complete the sieving process. However, there is not sufficient separation, and during the sieving process, a portion of the undersize is usually left on the screen. When the fine particles are sieved, the ease of sieving differs although the particles are smaller than the mesh. Particles of similar material and mesh size are difficult to pass through the screen, and it is more difficult to pass through the particle gaps in the lower layer of the screen.

 

 

How to control the vibrating screen in the other direction Choose the structure type of the mixer according to the conditions and requirements of use. If the seal is the main seal, a rubber seal mixer should be used. In the case of low pressure, the sliding mixer seal is better than the cut-off mixer. If the mixer is required to have a small force and a memory function, a sliding mixer should be used. If the air supply is poorly filtered, a cut-off mixer should be used. The diameter of the vibrating screen is selected based on the flow rate of the pneumatic actuator at the working pressure condition. At present, domestic production plants use free air flow (m3/h) for some mixers, and some use air flow under pressure (rr13/)?(usually called 0.?5MPa working pressure). Special attention is required. Try to select a mixer that is consistent with the desired function. If no other mixers can be selected or used in combination with multiple mixers. Minimize the types of mixers and avoid using special mixers.

The above is the content brought by the vibrating screen manufacturer to everyone, hoping to be of help to everyone.
