The air classifying mill operates based on the following steps: Material Feeding: The material to be ground enters the grinding chamber through a feed inlet. This can be achieved manually or through a controlled feeding system. Grinding Zone: A high-speed rotor or impeller rotates within the grinding chamber, imparting kinetic energy to …

A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …

Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …

Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.

The radial basis function (RBF) neural network is one of the most used in data classification. RBF neural networks consist of three layers: an input layer, a hidden layer and an output layer. The input layer corresponds to the input vector feature space and the output layer corresponds to the pattern classes [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.
