Quartz Sand Rectangular Vibrating Screen

The quartz sand rectangular vibrating screen is mainly used for the primary screening and classification of quartz sand.

Application of quartz sand rectangular screen

It is specially used for the screening and classification of silica sand. It can process quartz sand particles or powders in the range of 0.5mm-32mm, and can perform multi-layer screening at the same time.

Features of quartz sand rectangular screen

1. Double motor drive to ensure proper vibration, which is 3-6 times the output of ordinary screen machines, and the output can reach more than 20 tons/hour.

2. During the screening process, 6 sieve plates can be installed to separate quartz sands of different specifications, and 7 kinds of quartz sands of different specifications can be separated, which can be divided into coarse, medium and fine particle size grades.

3. Large inclination angle (generally 30°～60°) and large sieve hole (the size of the sieve hole is 2 to 10 times of the separation particle size), the screening efficiency is as high as 96%.

4. A distributor can be added in the feeding section to ensure that the screen meshes are evenly distributed on the screen surface, and at the same time play the role of buffering and protecting the screen surface.

5. The upper cover of the equipment is designed with a dust removal device. It can be easily connected with on-site dust removal equipment. In large production lines, multiple screening equipment can be configured.

Matters needing attention in quartz sand rectangular screen

In the quartz sand production line, the rectangular screen is widely used, and its large screening capacity plays a decisive role in the quality and output of the produced stones and sand. In the sand and gravel production process, the use of the screening machine should also pay attention to some problems:

1. Filter from coarse to fine

If the sieving is from coarse to fine, the sieve surface of the sand sifting machine overlaps according to the thickness, and the sieve surface with the larger sieve surface should be placed on the top, so that it is not easy to wear. If the excitation force of the screening machine is increased, the fine particles can fully pass through all the screen surfaces, thereby reducing the chance of inclusion in the coarse-grained product.

2. Screen from fine to coarse

In the case of screening from fine to coarse, in order to facilitate the discharge, the inclusion of fine particles aggregated in the discharge of various specifications is reduced. With this screening sequence, the structure size of the sand screening machine is larger, and all materials will pass through the fine screen surface first, which will accelerate the wear of the fine screen surface.

3. Appropriate screening methods should be used

In the screening process, wet screening or dry screening should be selected according to the mud content and water content of the materials in the sand screen. In the wet screening process, it is necessary to sprinkle water on the materials of the screening machine to reduce the viscosity of the mud and stone and prevent the screen holes from being blocked. If dry screening is used, it is generally used when the mud content or water content is small.

The above is the application of quartz sand in the vibrating screen. The quartz sand rectangular vibrating screen has high screening efficiency, and there is no mixing and stringing. It is a commonly used screening equipment for quartz sand or quartz powder.
