Along with the increasing popular of mining project, more and more people invested in producing stone crusher machine for mining process. And with the development of mining machinery industry, there are many kinds of mining machines in the market, so is the vibrating screen. Do you know how many kinds of screenings up to now? As far as I know, there are a number of types of mechanical screening equipment that cause segregation. These types are based on the motion of the machine through its motor drive. Then we will introduce them one by one. In addition, because of the limited time, we talk about the main kinds of them at first.

Circle-throw vibrating equipment - This type of equipment has an eccentric shaft that causes the frame of the shaker to lurch at a given angle. This lurching action literally throws the material forward and up. As the machine returns to its base state the material falls by gravity to physically lower level. This type of screening is used also in mining operations for large material with sizes that range from six inches to +20 mesh.

High frequency vibrating equipment - This type of equipment drives the screen cloth only. Unlike above the frame of the equipment is fixed and only the screen vibrates. However, this equipment is similar to the above such that it still throws material off of it and allows the particles to cascade down the screen cloth. These screens are for sizes smaller than 1/8 of an inch to +150 mesh. High frequency vibrating equipment is a shaker whose frame is fixed and the drive vibrates only the screen cloth. High frequency vibration equipment is for…
