6 Solutions to Prevent Blockage of Vibro Sifter Machine

It is unavoidable that blockage often occurs in the screening process. Because most of the material particles that need to be screened are irregular, the reasons for blockage are also varied.

How should we try to avoid blockage?

Here are 6 ways to reference:

1: Reduce moisture content

When the particle size of the material is fine or the sieve size is small, the material is easily stuck in the sieve hole, causing blockage. The increase of moisture will lead to the increase of the viscosity of fine particles, increase the possibility of agglomeration, and directly lead to blockage.

2: Drying ,dehydration or wet screening

When the moisture content in the material is more than 5%, it is necessary to screen the screening material by drying and dehydration. If the material is dried unconditionally, the screen surface and the screen hole should be selected pertinently.

Wet screening should be used when moisture content is more than 8%.

3: Reasonable adjustment of screen tension

Reasonable tension force causes slight secondary vibration between screen mesh and supporting beam, which effectively reduces the occurrence of blockage.

4: Crushing process

For materials with more flaky particles, crushing process is needed and screening is carried out.

5: Rationalize feeding speed or quantity

If the feeding speed or quantity is unreasonable, there will be excessive material accumulation on the screen surface of the vibration screening machine. It is suggested that the single feeding quantity be reduced.

Buffer hoppers can be installed at the feed port or quantitative feeding equipment can be used if it is really difficult to control.

6: Selection of special cleaning device

When the screening material is fine powder with light weight and high precision, the ultrasonic cleaning device is recommended.

When the screening material is large particulate matter with 60 meshes or more, the spring ball is often used as the cleaning device.
