Concentrator is generally used for concentrate concentration and dehydration of tailings before filtration in dress plants to concentrate the ore pulp with concentration of 20-30% to concentration of 40-70%. It is widely used for concentration and purification of slurry containing solid materials in industries of ore dressing, metallurgy, chemical industry, coal, construction materials, and source water and wastewater treatment, etc.

This concentrator is a new central transmission, automatic rake-lifting high-efficiency concentrator. It is widely applied to the handling of various industrial slurries, such as ore dressing, coal, metallurgical and chemical slurries, etc.
1.Large handling capacity (up to 2.5-4m3/m2) and high concentration efficiency.
(1)At the center, feeding is conducted at deep layer, and the technology of horizontal sediment reduces height of sediment and decreases the kinetic energy of solid particles.
(2)It is equipped with the dosing device, and there is a static mixer and three dosing points within the feed pipe, which can adequately mix the agent and materials and has good flocculating setting effect.
2.Hydraulic multi-drive, stepless speed regulating, high mechanical strength, with the function of overload protection.
(1)Central transmission device structure synchronously drives the outer gear ring of central slewing bearing for multiple hydraulic motor reducers, thus driving the spindle and rake to rotate. It can achieve stepless speed regulating and meet requirements of different working conditions.
(2)The spindle is a shaft with large-diameter thick-walled tube, with high mechanical strength and nice stability.
(3)The cover of transmission case is above the oil level, and never leaks oil. Lubrication of the transmission device is good.
(4)It is equipped with pressure control device; it will automatically stop when overloading and cause no harm to the equipment.
3.Hydraulic automatic rake-lifting, stable and reliable.
Hydraulic rake-lifting device and hydraulic driving device share a combined hydraulic power pack. The oil level reflects scraping resistance, and the spindle and rake will automatically lift or lower down along with the change of scraping resistance and will not press the rake.
4.Defoaming device is set up (optional based on nature of materials), and the overflow water becomes clear.
There is no foam produced on the tank surface, fine materials are sedimented adequately and rarely go into the overflow, and the overflow water becomes clear.
5.Simple transmission device structure, convenient for maintenance.
6.Automatic feed dilution system and underflow concentration monitoring system can be added as required by the working conditions of the user.
