Ommix Granule Sieve Machine

Granule Sizing and Quality Classification Solutions

Ommix Granule Sieve Machines are designed for the precise sieving, classification, and removal of unwanted particles from plastic granules, rubber granules, and various other granular materials according to their size in industrial production processes. Playing a critical role in quality control of cooled granules, especially those coming from extrusion or mixer outlets, our systems separate fine powders, large lumps, and unwanted foreign matter, ensuring consistency in final product quality and maximum production efficiency. With different layer options such as double-layer and triple-layer granule sieves, we offer seamless and automated solutions suitable for all classification needs.

What are Ommix Granule Sieve Machines and How Do They Work?

Granule sieve machines are industrial equipment that generally operate on the principle of vibration and separate granular materials according to their size through layers of sieve wire with different mesh sizes. These machines ensure that the granular products obtained after production meet the desired standards. Separating fine powders, substandard large granules, or foreign matter directly affects the homogeneity and quality of the final product.

Ommix Granule Sieves generally operate on the principle of high-frequency vibration. The sieve surface or layers are subjected to a controlled vibrating motion via specially designed motors or eccentric systems. As the fed granules move across the sieve surface thanks to this vibration, particles smaller than the sieve mesh size (dust, fine granules) fall to the lower layers. Granules of the desired size are collected from the middle layers, while larger particles (coarse granules, lumps) remain on the upper sieve surface and are discharged through a separate outlet. This system offers precise size classification and high separation efficiency.

Our single-layer granule sieves are ideal for obtaining only two different size fractions (e.g., desired product above or desired product below). They are an economical and effective solution for simpler classification needs.

Our double-layer granule sieves operate with two separate sieve layers having different mesh sizes. This allows for the simultaneous production of three different size fractions (e.g., fine powder, main product granules, and coarse/lumps). This type of sieve offers high efficiency for applications requiring more detailed size classification and separation.

Our three-layer granule sieves offer the possibility of obtaining four distinct size fractions using three different sieve layers. This provides superior flexibility and precision, especially for processes requiring complex classification and multiple product sizes. At Ommix, we can also develop multi-layer granule sieve solutions with more layers to meet the specific needs of your production line.

Why should you choose Ommix Granule Sieve Machines?
