The linear vibrating screen uses the vibrating motor as the vibration power source so that the material is thrown up on the screen and moves forward in a straight line. The material enters the feeding port of the screening machine evenly from the feeder and generates the number through the multi-layer screen.
The sieves and sieves of various specifications are discharged from the respective outlets. The utility model has the advantages of low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust overflow, automatic discharging, and is more suitable for pipeline operation. The tailings linear vibrating screen is mainly used for dehydration of iron ore, copper ore, gold ore, and aluminum mine tailings.
The factors that affecting screening effect
1. The width and length of screen
In general, the lateral length of screen can have a large effect on the overall working effect of screening machine. The larger the transverse length, the larger the sieve component; The longitudinal length of the screen has a great influence on the work efficiency. The longer the longitudinal length, the shorter the time taken to process the material. However, due to the limitation of overall design, it is impossible to increase the length in both the lateral direction and the longitudinal direction blindly, and the manufacturer needs to balance the consideration under the premise of mutual influence.
2. The angle of inclination of screen
When the screen is installed at an angle to the horizontal plane, the material on screen panel is easily slipped. The size of tilt angle directly affects its working efficiency. The greater the angle of inclination, the faster the material will move over the screening surface, which will increase the throughput per unit of time. However, this causes the time required for the particles to be sieved to stay on the surface to be greatly reduced, so that the probability of passing through the pores is lowered, which in turn affects the screening effect.
3. The size, shape and distribution of screen holes
If the size of sieve hole is larger, the sieved surface under the area can be separated by a larger amount of material, and the working efficiency is also higher. The size of the screening holes is mainly determined by the working requirements of equipment and the effects to be achieved.
Through the above analysis of the influence of screen structure on screening effect, we can know that there is not only one factor affecting the screening effect, but we need to combine the characteristics of materials to be screened, combined with the equipment itself to choose a way to influence small and fast screening.
