Screening separates a flow of material into multiple grades by particle size, these grades are then either further processed to an intermediary product or a finished product. Screening is an integral part of many dry material handling processes. In the context of screening or sieving equipment selection, the machines are evaluated on their ability to optimize product quality and screening efficiency. A sieve is used to process individual batches of a product, and a screen is used on a continuous flow of a product. There are many factors that are affecting the effectiveness of screens and sieves, for instance moisture, blinding, mesh size and wire diameter, capacity, cohesion, adhesion and the direction of approach of particles to the screen surface.
Magnetic separation systems are designed to remove metal contaminants from from bulk streams. Magnetic separators result in practically no product loss and are suitable for removal of regularly occurring and larger quantities of metal contamination in processing operations.
