Spiral Classifier: Importance & Types
The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and …
Which Effect Is Better Between Spiral Classifier & Hydrocyclone
The spiral classifier is based on the principle that the size of the solid particles and the specific gravity are different, so the sedimentation speed in the liquid is different. It is a kind of grading equipment that is pushed up by the screw and discharged to the top for mechanical grading. It can filter the material powder ground in the ball mill, …

Grinding Machines: Types and Selection Principles
Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball …
Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
5 Comparisons to Think Before Choose a Spiral classifier or
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 Separators
Advantages. It is widely used in the treatment of tungsten, tin, gold, platinum, iron and some rare metal ores, especially in the treatment of low-grade sand ores. Large processing capacity, high work efficiency, low cost and energy saving. The spiral separator has stable performance, clear ore separation, high enrichment ratio and recovery rate.
Screw Classifiers
Screw Classifiers. To be successful in a obtaining a uniform grind that is necessary to achieve a high percentage of recovery it is necessary to control the degree of fineness that the ore is reduced to. This is done by separating the fine material from the course and regrinding the coarse until it is fine enough for efficient mineral extraction.
Rake Classifier
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 …
