Screening machines for coarse and fine screening

In coarse or fine grain sieving, all particles that are above or below the desired grain spectrum and are thus too large or small for further processing are sieved out. These coarse and fine fractions are separated as reject grain and disposed of. In some cases, they can be fed back into the product process or recycled. Coarse grain and fine grain sieving have two main objectives:

Best possible processability of raw materials and intermediate products if they have to be available in a certain grain size in production process.

Ensuring the quality of the end product immediately before packaging by screening out unwanted coarse and fine particles.
