What Are The Uses Of Vibrating Screen In Crushing And Sand Making Operations?

The vibrating screen is mainly responsible for the screening and grading of materials in the crushing and sand making production line, and plays a connecting and transfer role in the entire crushing and crushing process. Although the vibrating screen does not look very conspicuous in the whole set of crushing equipment, it is undeniable that it is also one of the indispensable main equipment in material crushing and sand making operations. So, in crushing or sand making operations, what are the main uses of the vibrating screen? How to choose in procurement? This article will give you a specific answer.

1. Master the use, what are the uses of the vibrating screen in crushing and sand making?

1. Material pretreatment. If the overall particle size of the crushed material is quite different, in order to make the feed particle size meet the standard, screening and grading can be carried out first; for materials with not very large particle size, they can also be screened once before crushing and sand making to initially reduce the mud powder content in the crushed material.

2. Secondary screening. After the materials have been crushed in primary and secondary stages, they need to be further screened and graded. The materials that meet the processing standards will continue to enter the next stage of crushing or sand making. The materials that do not meet the standards will return to continue crushing until they meet the particle size standards for the next processing step.

3. Mud powder screening. After sand making, the materials are usually washed. The wastewater after sand washing is mixed with mud powder. In order to recycle the fine sand and dust lost during the sand washing process, a vibrating screen can be configured to screen and grade the mud powder in the sedimentation tank.

2. How to choose a vibrating screen to improve efficiency?

The vibrating screen is a screening device for material crushing. It plays a transitional role in the sand making process. Its working efficiency also affects the overall efficiency of the sand making production line. There are many types of vibrating screen equipment on the market. Different types of models have different screening efficiency and use value. Here are some suggestions for choosing a vibrating screen:

1. Characteristics of screening materials

When purchasing a vibrating screen, you should consider the characteristics of the subsequent screening materials in advance, including the requirements for the particle size of the material after screening, the content of impurities and other difficult-to-screen materials in the material, the moisture content of the material, the appearance and specific gravity of the material, and the clay content that is easy to paste the sieve holes.

2. Performance of vibrating screen

The screening efficiency of the vibrating screen is closely related to the screen area, number of layers, shape, size and area ratio of the sieve holes, and the movement mode, vibration frequency and amplitude of the vibrating screen. Generally speaking, the moving screen can make the particles of the screened material shake on the screen surface in a direction close to the vertical sieve holes, increase the vibration frequency of the material, high screening efficiency, and better screening effect; the fixed vibrating screen is the opposite, making the screening efficiency low and the effect poor.

3. Purpose of vibrating screen

Select different types of vibrating screens according to the occasions where the vibrating screen is used and the role it plays in vibration. Usually, circular vibrating screens are used for pre-screening of materials; large circular vibrating screens, probability screens, etc. are used for grading and screening of materials after primary and secondary crushing; linear vibrating screens are used for dehydration and other media removal treatments of materials; probability screens are used for mud removal and sand removal of materials.

4. The needs of crushing process

When selecting a vibrating screen, it is also necessary to consider the overall capacity of the sand production line, screening method, screening efficiency, and the inclination angle of the vibrating screen installation. Under the condition of meeting the requirements of the particle size and output of the machine-made sand product, non-metallic screens with larger screen size, larger effective screening area, suitable screen shape, and high screen opening rate should be selected as much as possible. At the same time, the installation angle of the vibrating screen should be adjusted to 15 degrees, which can effectively improve the effect and efficiency of screening materials.
