Vibro sifting machine

Vibro sifting equipment

1. Sifting

The lumps or growth that might have formed on the products after being stored for a longer period are removed.

They are passed through a mesh that opens, leading to finer materials.

For example, we have sifted flour in the food processing industry.

The product is released to the consumers after packaging and removing strings, insect larvae, tags, and insect fragments.

Therefore, this is a process that enables the products to attain their required properties.

2. Scalping

Here the lumps or some other unrequired foreign particles are removed from the refined products.

For example, twigs, tags, strings, and sticks, among others, are some of the foreign materials being removed by scalping.

The mesh opening size is larger than the product size.

This facilitates the easy scalping of more products, even in a small screen area.

This leads to effective and efficient separation of products.

3. Proof Sifting

This is the process that finally verifies the products.

For industries using this technology, the machine provides the final check on the product after completing the entire sifting process.

Proof sifting happens after the product has been filtered.

The process is either scalping or grading, depending on the installation type.

4. Screening and Grading

This process can sometimes be referred to as bolting, sifting, sieving, or even seizing.

It’s also another important task performed by the Vibro sifter machine.

It involves the separation of materials according to size.

It’s mostly useful when there is a task that is supposed to be performed by the separation of the materials.

Screening and grading can either be fast or slow, depending on many factors.

These factors include the type of material and its properties and the speed of the process of screening.

When the output is very low, a less screen area may be useful.

The user must understand important adjustments that can help improve machine efficiency.
