spiral classifier properties

Spiral Classifier for Mineral Processing

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material ...

An operational model for a spiral classifier - ScienceDirect

15/05/2016  A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

Principles of Spiral Gravity Classification

formed spiral would also slope inwards towards the supporting cylinder. This is the important angle β of fig.1 and is given by: tanβ = 2(D2-D1) (5) where D 1 is the cylinder diameter and D 2 is the formed helix diameter. For the previous example of D 1 = 100mm and D 2 = 500mm then β = 21.4˚. Commercial separators usually have an added geometrical feature – a steady increase in the radius ...

Mineral processing - Wikipedia

The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.

Measurement of Overflow Density in Spiral Classifiers ...

spiral classifiers. A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier has two outputs: the “underflow”, formed by sedimented coarse solids; and the “overflow”, in the form of an ore slurry with fine suspended solids particles. For proper ...
