Quartz sand linear probability screen 1030 flat vibrating screen

Quartz sand linear probability screen 1030 flat vibrating screenWhen screening on a probability sieve, the aggregation and separation results of mixed materials with different particle sizes are shown in. The sieve box of the probability sieve vibrates in a directional straight line. When the material being screened experiences a continuous bounce due to force on the sieve surface, some particles will pass through the sieve hole and fall onto the next layer of sieve surface. Due to the difference in mesh size among different layers of screens, the screens with larger mesh sizes occupy the upper layer and are then arranged from top to bottom in order of mesh size. However, the particle size of the products under each layer of sieve is arranged from the feeding end to the queuing end, from small to large. From the entire screening box, it can be seen that after the material passes through the screening process and is discharged from each layer of screen surface, the particle size queuing order is from smaller to larger. From this, it can be seen that the entire screening process of probability screening, whether vertical or horizontal, follows the arrangement pattern of particles according to their particle size. The fundamental reason is that particles of different sizes have different screening probabilities. There are differences in structure and working principles between ordinary screening machines and probability screens; However, the probability principle of material passing through the sieve is the same

Install a linear probability sieve mesh

1. Due to the direct impact of the tension of the screen mesh on the screening efficiency of the linear screen, it is necessary to tighten the screen mesh when installing the linear screen mesh;

2. The installation of cleaning rubber balls should be determined based on the number of sieved materials and the difficulty of screening, and blind and disorderly loading should be avoided;

3. When the mesh size of the screen is high or the material proportion is large, a suitable mesh size supporting mesh should be installed below the screen (the supporting mesh mainly plays a supporting role, which can effectively reduce the pressure of materials on the screen and extend the service life of the screen);

4. To avoid mixing, the linear screen frame must be assembled into the screen box as required, and the elongated screen must be extended into the corresponding discharge port;

5. When installing the pressure plate, attention should be paid to maintaining the flatness of the pressure plate and lining it with a sponge sealing strip with strong elasticity to evenly lock it. This is the key to mixed grading and an important factor affecting the lifespan of the screen mesh;

6. After the installation of the linear vibrating screen mesh is completed as required, a small amount of material must be used to test the material and screening situation of the linear screen. If the material is evenly transported forward, the grading is accurate, and there is no mixing phenomenon, the linear screen can be put into use. On the contrary, if uneven phenomena such as material deviation and stacking occur, the flatness and evenness of the linear sieve mesh surface should be adjusted. If there is a phenomenon of material mixing, the sealing and tightness of the sieve should be checked.
