Sieving and Classifying

Using our sieving equipment we are able to separate large or fine particles. We can also use 2 decks so any oversized and fine particles can be removed at the same time

The types of sieves we use are:

  • Circular (Algaier & Russell Finex)
  • Rectangular (Locker)
  • Sifters (Powtek)

At Exwold, we have a number of different types of sieving equipment available to separate materials. This processing technique is also known as screening.

As well as sieving through a screen, materials can be separated using a classifier. A classifier uses centrifugal forces to separate different size particles. Our Air Classifier Mill (ACM) uses this technology to keep larger particles inside the milling chamber, thus classifying the material.
