An operational model for a spiral classifier
2. Spiral classifiers. 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.

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.
Spiral Classifier Information Technology Solutions
The typical range of feed to a spiral is 20 mesh (850 μ) to 325 mesh (45 μ). The slope of the spirals is 3.5 inches vertical per foot of horizontal distance. These units are primarily constructed from carbon steel, but are available in stainless steel, if required. Conditions that affect classification in a spiral classifier are: 1.

Principles of Spiral Gravity Classification
if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The 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 ...
