Different types of vibrating screens have restrictions on the applicable materials and scope. Some are suitable for particle and powder screening, and some are suitable for impurity removal and filtration. In general, the larger the screen surface of the vibrating screen, the longer the material screening time. , The longer the movement track of the material on the screen surface, the better the screening effect. This is only applicable to common types of materials. Like cylindrical, flake and irregular shaped materials, even if these conditions are met, the material will block the mesh and the screening will not be clean.
The tumbler screen is most suitable for sieving cylindrical, flake and irregular materials. Because the tumbler screen can use multiple types of cleaning devices according to the type of material, which can effectively reduce the probability of mesh clogging due to the shape of the material. However, some materials will have strong adsorption, easy clumping, and high static electricity when sieving by vibrating screen. Some materials themselves have the characteristics of high density and light specific gravity. This will easily block the mesh and reduce the machine’s performance. Efficiency and screening effect. Therefore, a net cleaning device must be added to the swing screen.
The structural characteristics of the tumbler screen and the running track of the material are different from those of ordinary vibrating screens. Take the rotary vibrating screen for example. Its principle is to use the exciting force generated by the vibrating motor to make the material move in three dimensions on the screen surface, while the tumbler screen uses the motor to drive the belt to make the screen body appear circular. The trajectory shakes, so as to achieve the purpose of screening. This type of tumbler screen rarely has dust flying during sieving and has low noise. If the motor used in the tumbler screen is not properly sealed, there will be material leakage, large dust, and high noise.
Also, compared to ordinary sieving machines, the tumbler screen has higher screening accuracy and better screening efficiency. The ordinary rotary vibrating screen frame is equipped with a bouncing ball, which hits the screen while the screen machine is running to achieve the effect of cleaning the screen, but the effect of using ordinary rotary vibrating screen is not very good for sheet-like and cylindrical materials. In addition to the bouncing ball in the tumbler screen, there are many types of net cleaning devices, such as a special brush on the screen surface, which can clean the screen surface when the screen is working, thereby effectively solving the problem of mesh clogging. problem.
The tumbler screen is a large-capacity, high-precision, high-efficiency screening machine. For users who require high precision and low investment costs, the swing screen is your first choice.
