Types of classifiers

Jun 07, 2017DRY CLASSIFICATION Dry classifiers are based on the air fluidization. Air classification is a process of separating categories of materials by way differences in their respective aerodynamic characteristics. Dry classification using separation by centrifugal force typically covers the range of 5 micrometers to 150 micrometers. The process Get price

Classifying Screens

Mar 03, 2011From what I've always been told and what I do and seems to work well for me is too classify to 4 to 5 times of the size of the gold in the area your working and check the results in your sluice, if you're only getting 30 mesh and smaller gold ideally classifying to 2 to 3 times the size of the gold will give you better results, the reason behind this is if you have gravel that is heavier than Get price

Mechanical screening

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size..
