Vibrating screen in stone crusher plant

In the sand and gravel aggregate production plant, the crushing and screening machine is the key equipment, and its environmental protection performance is directly related to the environmental protection level of the whole production plant. In the stone crusher plant, the main functions of the vibrating screen are below:

1. Material pretreatment.

If the crushed material partical size is quite different, in order to meet stone crusher feeding size standard, it can be screened and classified firstly. For small size material, it can also be screened before crushing to reduce the mud powder content.

2. Secondary screening.

After the materials have undergone primary crushing and secondary crushing respectively, the materials need to be further screened and classified. If the particle size meets the processing standard, it will continue to enter the next crushing stage. If the particle size does not meet the standard, return to continue crushing until it meets the standard. 

3. Mud powder screening.

After sand making, the materials are usually washed with sand. The sewage after sand washing is mixed with mud powder. In order to recover and reuse the fine sand and dust lost in the sand washing process, a vibrating screen can be configured to clean the sedimentation tank. The mud powder is collected by screening and classification.

FAQ:

1. How to choose vibrating screen?

When choose vibrating screen, it need to consider the screening material characteristics and its use, the capacity of stone crushing and screening plant,  screening method,  screening efficiency and the installation angle.

2. How effective is a vibrating screen?

Linear vibrating screen has the maximum screening efficiency of 65.92% for first 10 minutes of screening and reduced up to 59.34% for 60 minutes of screening. The reduction in screening efficiency with respect to screening time is due to the screen blinding.

3. Where are vibrating screens used?

Vibrating screen is widely used in mining metallurgy, coal, building materials, chemical industry, cement, glass, grain, medicine and other industries due to its simple structure, small floor area, convenient installation, easy maintenance, low noise, reliable performance and other advantages.
