Grit Classifier Basics: What is a Grit Classifier?

All types of grit classifiers typically receive a grit slurry from an air lift pump or a grit pump(s). Most classifiers receive a grit slurry that is 1-3% solids mixture. The hopper of a traditional grit classifier is designed for the shortest retention time to allow heavier grit to settle, but not the lighter organic material.

Classifier Categories 85 solids by weight in the fluid for very fine sizes, and up to 35% solids if the particles are coarse. The fluid used with sizing classifiers is also generally water, although there are some which use air as their medium. Sorting Classifiers These utilize hindered-settling and have two characteristics in common to all the

Particle fractionation by air classification

An air classifier is capable of separating materials by a combination of differences in size, shape, and density of the particles present in the material. Air classification is a method of separating powdery, granular or fibrous materials by settling air velocity and combined with the particle size, particle density and particle shape.

Classifiers | Article about classifiers by The Free Dictionary

Hydrocyclones and centrifuges are types of centrifugal classifiers. Pneumatic classifiers are subdivided into chamber and centrifugal classifiers, with the latter being used more often. They consist of a blower, a distributing plate, and a centrifugal bladed wheel which spins the large particles toward the walls of the inner cone.
