Everything you need to know about screening
Crushed materials are often angular and require different screening. The presence of fines can increase the feed speed of industrial screening. Moisture forces the particles to stick together, which limits the efficiency of the process. The difference in size between particles is a key factor. Screening systems: types of screening
