Dewatering Machine
In mineral processing flow, the concentrates and tailings produced by different of treating methods must be dewatered, so these pulps products can convert to a transportable state. We provides mining and mineral dewatering machines including dewatering screen, thickener, rotary dryer, filter press, etc.

Dewatering screen
Capacity: customizable, 10-150 tph
Screen Sieve
Material: PU, PE, and others materials
Hole size: from 0.2 – 0.5 mm
Advantages:
high dewatering rate, low noise

Thickener
Capacity: 5-400 t/24h
Application: dewatering process of concentrates and tailings in the mineral processing plant. It is specifically designed for the beneficiation industry and tailing processing.

Rotary dryer
Capacity: 1-40 tons/hour
Suitable materials: drying powder, lump, granular materials such as coal slime, ore powder, slag, sludge, clay, fly ash, etc.

Filter press
Capacity: 50-120 m² per hour
Application: gold, coltan, tin, tungsten, iron, manganese tailing processing

Disc Vacuum Filter
Capacity: 0.85-1.2 t/h·m² (Different material processing capacity is different)
Application: It is suitable for fine material filtration and dehydration of fine tailings and non-ferrous metal concentrates in mineral processing plants, etc.
Filtration
Filtration is the separation of a suspension into a solid filter cake and a liquid filtrate by passing it through a permeable filtering material. Important factors in this process are the properties of the suspension (e.g., size distribution, concentration), the properties of the filtering materials (e.g., the width and shape of pores), and the forces applied to the suspension. Filtration is carried out in gravity filters (screens, dewatering bins), in centrifugal filters (screen centrifuges), in vacuum filters (drum cell filters, disk filters), or in pressure filters (filter presses). Such devices make it possible to produce filter cakes containing 8 to 15 percent moisture.
Thickening
In the process of thickening (also called sedimentation), the solids in a suspension settle under the influence of gravity in a tank and form a thick pulp. This pulp, and the clear liquid at the top of the tank, can be removed continuously or intermittently. In comparison with filtration, thickening offers the advantage of low operation costs; on the other hand, it has the disadvantage of leaving a higher moisture content in the pulp. For this reason, the dewatering of pulps containing fine particles often involves a combination of thickening and filtration. The thickening of finely grained pulps is often aided by the use of flocculating agents.
Drying
The removal of water from solid materials by thermal drying plays a significant role in modern mineral processing. A great number of dryer types are available. Convection dryers, employing a flow of hot combustion gases to remove moisture from a pulp stream, are the most common. To this type belong rotary drum, conveyor, and fluidized-bed dryers.
