The Concentration Equipment is a new type of dewatering device that combines the filtration characteristics of the mud layer. Applicable to concentrates and tailings demineralization, widely used in metallurgy, chemical, coal, non-metal dressing, environmental protection and other industries. Thickeners play a vital role as solid-liquid separation devices. How to effectively improve the efficiency of the concentrator? Golden Machinery has summarized some experiences.

The tank of the sedimentation tank is designed as a shallow layer

In general, the settling tank of the concentrator has nothing to do with the capacity of the concentrator, mainly depending on the settling speed and the settling area of ​​the settling tank. However, if the tank is shallow and the material falls, the settling velocity will gradually decrease as the pulp density increases.

Segment feeding

The feed roller of the high efficiency concentrator is placed in the center of the concentrator. It consists of three mixing chambers connected in series in the vertical direction. Each mixing chamber can be fed with a small angle and a small angle. According to the stirring strength, the design is performed from top to bottom from strong to weak to prevent breakage when the flocs are formed. Each chamber is administered separately and may or may not flocculate.

Overflow design is unreasonable

Some concentrator overflow tanks are built in, away from the top edge of the tank and covered by wood. The staff could not observe the overflow ditch throughout the operation.

Rational use of flocculants

The size of the flocs determines the rate of settling, which is related to the molecular weight and rate of addition of the flocculant. The use of a flocculant having a molecular weight of 5 to 20 million and added at a slow rate contributes to the formation of large flocs. It is very important to determine the agitation speed based on the time at which the ore particles form flocs. The stirring speed is pleasant at the beginning, so that the flocculant is completely and uniformly dissolved in the pulp.

Wet dressing usually requires some products (products) to be dewatered. Most of the fine-grained concentrates are dewatered by concentrated filtration or two-stage or concentrated filtration and drying. The tailings generally need to be transported to the tailings pond intensively; sometimes, intermediate products (intermediate mines) are also needed in the sorting process. Concentrate on meeting the centralized requirements of the next phase of operations. It is usually treated with a Concentration Equipment.

At present, the most widely used in the world is still the ordinary mechanical discharge concentrator. In recent years, high-efficiency concentrators, slant plate concentrators, slant plate concentrators, sloping plate thick boxes, etc. have also been developed and applied.

Ordinary concentrators have two types of high-efficiency concentrators, center drives and peripheral drives, equipped with special devices, the addition and mixing of flocculants, and high settling speed; some have no sloping plate settlement area. The unit area is highly efficient and can reach 7-8t/(m2·d). The instrument is small in size and can be used in small and medium-sized concentrators. Especially in the case of small plant area, the concentrator must be installed indoors.

Inclined plate concentrator: This concentrator is a new type of high efficiency and dense equipment. There is a rectangular box at the top that is connected by a tapered funnel. The mud is sent to the width of the two plates across the frame and then passed between the gap spaces between the upper sloping plates. During this process, ore particles settle between the plates, so the upper inclined plate is called a thickened plate. On the solid deposit on the surface of the board, slide down your weight and then drop the gap between the plates. Finally, the sand cone is discharged from the bottom of the conical funnel, its discharge and concentration of gate valves or nozzles of different diameters are adjusted. The overflow is discharged from the overflow tank.

In recent years, as the market demand for mining and processing has also changed, the price of thickeners has fluctuated significantly. Different specifications, concentrators are available in a variety of prices. It must be clear that the price of the concentrator varies with the needs of the market and the price is different. For customers, the most valuable reference price negotiation is not published on certain websites, but published on a reliable thickener manufacturer's official website.
