The GRTS rotary 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.
- 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 oscillating movement of the rotary separator allows for an even distribution of the product over the sieves, ensuring thorough cleaning.
For particularly dirty products, the use of a GVSP vibratory separator is recommended, as its vibrations help perform a more intensive, albeit less precise, cleaning compared to the rotary separator.
