rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …

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.

An analytical and experimental technique which permits determining increase in the pump efficiency quickly and with high precision at the change in pump design and/or operating mode was developed and allows increasing the efficiency assessment accuracy and cavitation characteristics of lowflow highspeed screw centrifugal pump.
Structure of Spiral Classifier. The spiral classifier mainly consists of the following components: Transmission Device: Includes an electric motor, reducer, cylindrical gear pair, and bevel gear, responsible for driving the rotation of the spiral.; Spiral Body: Composed of a hollow shaft, supports, spiral blades, and lining iron, which is the main working part of …
The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4) Optimum Operating Conditions of ... ="Gravity Spiral …
Spiral classifier is mainly composed of the driving device, the spiral body, the groove body, the lifting mechanism, the lower seat and discharge valve. The machine base adopts channel steel, the body adopts welded steel plate. Screw shaft parts use the pig iron, and wear resistance. Working Principle:
It can conduct different grading operations based on the principle that different solid particles have different settling velocities in the liquid. Spiral Classifier. Chute Length:≤3000-14300mm; Screw Diameter:300-3000mm; Spiral Classifier for sale. Spiral Classifier, as a key equipment in modern mineral treatment process, plays an important ...

The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster …
Troubleshooting of 5 common faults of spiral classifier. June.18,2020. The spiral classifier is used in the artificial sand production line and the commonly used classification equipment in the washing operation. It is mainly used to wash off the mud powder in the sand so that the artificial sand can reach the standard of construction sand.
If ore grinding and classification are closed loop operation, the return sand discharged from the ore discharge mouth still goes into the mill for further grinding. Classifiers normally form closed loop operation together with mill. 1. Good adaptability 2. Easy maintenance 3. High classifier efficiency 4. Simple and reliable structure 5.
