5 Tips for Selecting Vibrating Screen Separator

Vibrating screen separator is a kind of equipment that uses vibrating motion to separate particles of different sizes from each other, vibrating screen can be used for dry powder or granular materials as well as wet screening products and liquids. When choosing a vibrating screen separator, you need to provide the following requirements:

1. It is necessary to remove the specific gravity, viscosity and water ratio of the screening material.

2. It is necessary to analyze whether the screening material contains static electricity.

3. It is necessary to know whether the shape of the screening material is a specification.

4. The screening rate of the material to be screened is the ratio of the screened material in the entire material.

5. The processing capacity of materials that need to be screened.

In addition to considering the above impacts, the following basic principles should be observed:

1. After determining the sieving area, the width of the sieve surface should be at least 2.5 to 3 times the size of the bulk material to prevent the sieve from being blocked by the bulk material.

2. In order to keep the vibrating screen separator in good working conditions, the ratio of the length to the width of the screen should be selected within the range of 2 to 3.

3. Reasonable screen surface material and structure should be selected to suit the working conditions.

4. Determination of sieve size, for fine sieves, curved sieves, and linear vibrating sieves for fine particle sieving, the sieve slit size is 2 to 2.2 times the separation particle size. The size is no more than 3 times larger; for the vibrating screen, for the screening of medium-sized materials, the sieve size is 1.2 times the separation size; for coarse-grained materials, the sieve size is 1.05 of the separation size.

5. Determine whether to use a double-layer or multi-layer screen. When the particle size range of the material to be screened is wide, when the double-layer screen is used as a single-layer screen, the processing capacity of the screening machine can be improved, and the lower screen can be protected, so that the service life of the lower screen can be extended. The selection of the sieve size of the upper sieve of the double-layer sieve should generally be determined according to the characteristics of the ore feeding granularity. It can be considered that the sieve size of the upper sieve is equivalent to 55-65% of the raw material size as the sieve hole. size.

6. Determine the effective working area of ​​the vibrating screen separator. The sieving area calculated according to the requirements of the production process is the effective area of ​​the sieve, and the specification of the sieve is the nominal area of ​​the sieve. For the vibrating screen used for sieving medium-sized materials, the effective sieving area should be 0.8~0.85 of the nominal area of ​​the sieve. times. Of course, this is closely related to the sieve opening rate on the sieve surface.
