The GVSP vibrating separator is used in cereal cleaning to separate impurities based on particle size. The product flows over a first perforated sieve, where the cereals pass through the holes, while larger impurities are directed to the coarse residue discharge. Then, the cereals move onto a second sieve with smaller holes, which retains the product until discharge, while finer particles (such as sand, soil, and broken grains) pass through the holes and are collected separately.
The machine consists of:
- An oscillating central body, connected to a fixed structure via fiberglass rods that allow movement and secure the screening frames.
- A rotating counterweight, driven by an electric motor, which generates the movement.
- Upper frames, made of S235JR carbon steel or stainless steel, for the separation of coarse impurities.
- Lower frames, also made of S235JR carbon steel or stainless steel, for the separation of dust and fine fractions.
The screening frames can be quickly removed from the back for easy maintenance and replacement of the sieving meshes.
The rotary separator is often combined with an air separator to further remove light fractions, which is installed at the machine’s discharge and can also be equipped with a magnetic device if necessary.
The vibratory separator is particularly suitable for very dirty products, as the vibrations transmitted to the product facilitate intensive cleaning.
For a product that has already undergone a pre-cleaning phase and requires more thorough cleaning, the use of a GRTS rotary separator is recommended: its oscillating movement allows for an even distribution of the product over the sieves, ensuring more effective cleaning.
