To improve the screening efficiency of linear vibrating screen, these aspects cannot be ignored!

Linear vibrating screen is one of the main equipment for crushing and screening, and it is also the key equipment to provide qualified materials for subsequent operations. Its screening efficiency directly affects subsequent operations. In the actual dressing plant, the main factors affecting the screening efficiency of the linear vibrating screen include: material properties, screen surface structural parameters, vibration characteristic parameters and so on. Next, the vibrating screen manufacturer will specifically analyze how the above aspects affect the screening effect of the linear vibrating screen.

Material properties

The nature of the selected material is one of the main factors affecting the screening efficiency of the linear vibrating screen, and its material properties are mainly reflected in the loose density of the material, the particle size of the material, and the shape of the material.

1. Loose density of selected materials

Generally, the loose density of the material is large and the bulk particles are easy to pass through the screen, and the screening efficiency is high. The effective screening area of ​​the sieve is reduced, which in turn affects the screening efficiency. In order to ensure the screening efficiency, it is necessary to control the bulk density of the selected materials.

2. Selected material particle size

The particle size of the selected material is also an important factor affecting the screening efficiency of the linear vibrating screen. The particle size of the material entering the sieve should meet the size of the sieve hole. Small particles are easy to sieve, and large particles are not easy to sieve. To ensure the screening efficiency, it should be strictly controlled. Into the sieve material particle size.

3. The shape of the material entering the sieve

The shape of the material entering the sieve will affect the sieving performance. Generally, the particles are fully ground and are easier to sieve than the mineral particles of the specification. The sieving rate of materials with irregular particle shapes such as long strips and flakes is poor. Therefore, it is necessary to ensure that the particle shape of the crushed material conforms to the sieve hole standard.

Screen structure parameters

The structural parameters of the linear vibrating screen are mainly reflected in the length and width of the screen surface and the size and shape of the screen hole.

1. Length and width of screen surface

The length of the screen surface of the linear vibrating screen mainly affects the screening efficiency, and the width of the screen surface mainly affects the productivity. The sieve surface of the linear screen is longer, the residence time of the material on the sieve surface is longer, and there are more opportunities to pass through the screen, which will improve the screening efficiency. In fact, the width of the screen surface has different effects on the screening efficiency and the length of the screen surface on the screening capacity.
