This document discusses types of classifiers used in mineral processing. There are two main types - wet classification and dry classification. Wet classifiers separate minerals based on differences in settling velocities in water, and include spiral classifiers, hydraulic classifiers, and hydrocyclones.

In mineral processing, fluctuating hardness of the feed material requires using a control mechanism. With harder material, the mill discharge becomes coarser. Consequently, the recirculated load and the solids mass flow having to be treated by the hydrocyclones are increasing.
The first is used to select commercial hydrocyclones that fulfill given capacity and classification conditions and the second, based on experimental work, is used to …

3. 3 The size distribution of the particles must be controlled for a number of reasons at various stages of a mineral processing plant: To enable undersized material to bypass the crushing or grinding circuit and to retain oversized particles for further size reduction, To provide an optimum particle size material for efficient processing in the …
No large-scale investments are planned in the mining industry, and developments will mainly be made in operational optimisation, through automation or processing improvements such as adjustments to equipment, reduced losses or increased product quality. For all of these reasons hydrocyclones will play a very important role in …

Multotec equipment is installed in 100 countries Materials of construction:
19.3.1.3 Hydrocyclones. Hydrocyclones are useful for the removal of suspended solids from ballast waters by liquid–solid and liquid–liquid separation. This technology is also effective for the dewatering of microalgae cultures. ... The hydrocyclone is a widely used classifier in the mineral-processing industry. It is installed in close ...
Classification in mineral processing is the operation of separating particle mixture components into two or more fractions according to size, with each resulting group more uniform in this property than the original mixture. There are two types of equipment for this purpose, mechanical classifier used in all mineral processing
Solid-liquid, liquid-liquid, and dense media hydrocyclones are used for classification and separation processes in mineral processing. Hydrocyclones separate particles by density and size using centrifugal force. Solid-liquid hydrocyclones separate solids from liquids, liquid-liquid hydrocyclones separate immiscible liquids, and dense media …
The hydrocyclone operation consist of having the ore slurry pumped into its feed inlet, the ore is then separated by size with the fine material coming out of what is referred to as the "OVERFLOW" via a Vortex Finder. The mineral that still requires grinding is named the "UNDERFLOW" via the Apex Finder. These two … Read more
Usually, in the wet process of ore resource sorting, fine mineral particles with a particle size less than 150 μm produced in the processing stage are discarded as wastes, discharged in the form of mud and accumulated into tailings dams (Lyu et al. 2019).With the unprecedented demand for iron ore, the steel industry has accumulated …
It looks as if one D15 hydrocyclone could handle your flowrate at 10 to 20 psi pressure drop, in case you allow particles of less than 50 - 110 microns to be present in the clear water, or else, you should go for a cluster of D6 hydrocyclones (5 or 6 of them) if your overflow cut point for particle size is 35 - 75 microns.
