Thickener
Capacity: 1.3-1440 t/d
Application: Metallurgy, chemical, coal, non-metal ore dressing, environmental protection, and other industries.
- Adding flocculants to increase the particle size of settling solid particles, thus speeding up the settling speed.
- Installing inclined plates to shorten the settlement distance of ore particles and increase the settlement area.
- Giving full play to the functions of flocculation, filtration, compression and enhancement of the treatment capacity of the thick phase layer of mud deposition.
- Equipped with complete automatic control facilities.
Thickener Structure
The thickener (high-efficiency thickener) generally consists of a thickener tank, a truss, a transmission, a truss lifting device, a feeding device, a discharging device and a signal safety device.
Thickener Working Principle
The main feature of the concentrator (high-efficiency concentrator) is to add a certain amount of flocculant to the slurry to be concentrated, so that the ore particles in the slurry form floccules, accelerate the sedimentation speed, and thereby achieve the purpose of improving the concentration efficiency.

Thickener Introduction
The thickener is applicable to concentrate and tailings dewatering treatment in the mining application, widely used in metallurgy, chemical industry, coal, non-metallic mineral processing plant, environmental protection, and other industries. In fact, the high-efficiency mining thickener is not a gravity separation equipment, but a piece of dewatering equipment combined with characteristics of mud filtration.
A good concentrator settling process must have three stages that are not in short supply. That is the stage of coagulation and destabilization, the stage of coagulation and granulation, and the stage of filtration and compression. However, the realization of these three stages must have certain equipment to ensure that the flocculation reaction cannot be sufficient, and the effect of solid-liquid separation is impossible to achieve the desired state.
As the large flocs gather more and more, the ideal dense phase layer at the bottom of the deep cone concentrator is formed. In the upper part of the dense phase layer, thicker and less stable flocs are deposited, which are essentially a floating filter medium that has a very beneficial intercepting effect on small particles that escape with the upflow. The sediment at the bottom of the dense phase layer, under the combined action of the larger head and the material gravity, can obtain a large pressure in the bottom stream of the deep cone concentrator, so that the concentration of the material to be discharged is greatly improved.
