Does the rocking vibrating screen really have a large processing capacity? The answer is no!
Swing vibrating screens and linear vibrating screens are widely used in many industries. Among them, linear vibrating screens and circular vibrating screens are used for classification operations in coal screening. Because the linear vibrating screen moves in a straight line, the advantage is that the screening output is high, while the circular vibrating screen moves in a circular shape, the output is relatively low but the accuracy is high, so it plays a different role in the screening of coal. Fully enclosed structure, no dust overflow. Swing vibrating screen is mainly used for dehydration screening, desliming screening and de-intermediation screening, that is, filtering before the circular vibrating screen. In coal screening, the classification operation is an important part. Screening The price of medium-refined lump coal is more than 50% higher than that of ordinary coal. Therefore, to improve the accuracy of coal, it is necessary to carry out grading and screening. At this time, the linear vibrating screen plays a role in the preparation of raw coal.
Compared with the rotary vibrating screen, the linear vibrating screen has many advantages, but the linear vibrating screen also has defects such as insufficient screening accuracy. This shortcoming determines that it is not suitable for precision screening, but it is suitable for some applications that do not require high accuracy. But for the screening of materials that require a large output. The linear vibrating screen is composed of two parts: the base and the vibration. The vibration motors are respectively installed on both sides of the rectangular screen frame of the linear screen. The vibration is generated through the elastic rubber connection. The phase angle of the vibration motor and the weight can be adjusted to increase the amplitude and excitation force.
The linear vibrating screen can be used in single layer or multiple layers (six layers), and because the base is equipped with lifting rods, the inclination angle of the screen surface of the linear screen can be adjusted to achieve the ideal screening effect. The vibration motor is used as the vibration source to throw the material on the screen, continuously jumping and spreading out, and at the same time making a straight motion forward. The bottom of the screen frame is equipped with a support base and is divided into several grids. Each grid has several rubber balls to make them impact when vibrating, so as to achieve the effect of cleaning the screen and solve the phenomenon of material sighting. The storage hopper is flexible to open and close, which can correctly control the flow of materials, evenly enter the wire mesh and spread out, so that the wire mesh can be fully utilized, and the screening accuracy and screening output of the material can be ensured.
The swing vibrating screen is mainly used for the final screening of coal. After the vibrating screen is started, the vibrating motor drives the vibrating screen box to perform a directional jumping motion. It can be seen that the circular vibrating screen is beneficial to the difficult-to-screen materials to penetrate the screen, and the arc-shaped screen surface is again The effective area of the screener is increased, which can meet the requirements for screening coal. The screen has a high utilization rate, a large unit area, is not easy to see, and is easy to replace; the screening accuracy is more than 96%, and the processing capacity is large.
The installation is simple, operation and maintenance are convenient; when sieving coal, the linear brake screen is used for screening and filtering. Although the processing capacity is large, the screening accuracy is not high, so a circular vibrating screen is needed for screening. All in all, the two are combined to make use of their respective advantages to make coal screening and meet the standards. Continuous production, single-layer or multi-layer automatic classification screening; vibration motor is used for energy saving and low noise;
