Installation for pneumatic classification of mineral components contains hopper 1, the transient chamber 2, classificatory systems, 3 5, consistently communicated between a product pipelines 6 7. The hopper 1 through the transition chamber 2 is communicated with the first in the course of presenting the mineral components of classificatio the 3 ...
Classification is defined as a method of separating mixtures of mineral particles into two or more products according to their settling velocities in water, in air or in other fluids. Classification is performed on the basis of the velocity with which the material particles fall through a fluid medium generally water or air.
Pneumatic classification relies on classification of powdered, dry material suspended in a moving gas to obtain two distinct fractions fine and coarse. The principle of separation is based on the effective size of the particles by difference in dropping velocity in a gas.
Spiral Classifier In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.
Classifier. , an apparatus for separating mixtures of mineral particles into fractions according to size, shape, or density. Depending upon the medium in which separation of the materials occurs, classifiers are divided into hydraulic and pneumatic. Depending upon the force used, there are gravity classifiers ...
Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi cylindrical trough inclined to the horizontal. The trough is provided with a slow rotating spiral conveyor and a liquid overflow at the lower end.
