Spiral Classifier - Mineral Processing

The spiral classifier is widely used in the classification of the grinding circuit of the concentrator and the operations of washing, desilting and dewatering. Its main advantages are simple equipment structure, reliable work and convenient operation. 1. It is used for the separation of machine-made sandstone powder, which can control the content of machine-made sandstone powder very ...

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 . The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral. As the particles flow down the spiral, various forces pull the ...

01/01/2016  Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller classifiers have raking capacities as low as 1.5 t/h. To some extent, the capacities depend on the number and design of the ...

The feed is given a high tangential velocity and is introduced near to the top of the unit. The gas flows in a spiralling fashion towards the bottom end where it experiences a flow reversal and passes up as a central core. In the cone classifier, the central core of gas actually flows in a reverse spiral up the wall of a central feed. Under the influence of centrifugal force, coarse particles ...

The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field.
