Thickener is widely used in dressing plant, sewage disposal plant and other relevant departments about the dehydration and enrichment work, according to the transmission methods it can be divided into central transmission thickener and the peripheral transmission thickener. Thickener working principle is as follows.
Central transmission thickener is mainly composed of enrichment pool, rake, and transmission device, rake lifting device, feeding device, discharge device and the safety signal devices. The bottom of the thickener is designed to be the cone, the solid particles of the pulp will become the big flocculent-shape group under the action of the flocculent. These flocculent-shape groups combined with ore particles and the flocculent agents will sink to the bottom because of their own gravity. And will be scraped to the discharge mouth by the scraper continuously and then are transported for the next work by the pump. The upper clear water flows to the overflow tank to be reused.
There is a vertical shaft in the center of the central transmission thickener, and a rake is fixed on the lower end of the vertical shaft. There is a certain angle between the rake and the horizontal plane, typically 8 ° ~ 15 °. The vertical shaft is driven by a motor fixed on the truss, which is spurred by cylindrical gear reducer, the intermediate gear and turbine gear reducer. The central transmission thickener has a rake lifting device. When the torque of the rake is too large, it can be lifted manually or electrically. Reducing the rake suffered torque by reducing the thickness of the sludge to prevent damages of the transmission device and the scraper device.
There is still a certain gap with foreign central transmission thickener in specifications and qualities. Our central transmission thickeners are small scale, generally no more thanφ100.
In the mineral processing plants, the thickener is used to increase the concentration of the minerals, which is separated by the flotation or dewatering. ... [more]
Gold mining method. There are gold gravity mining processing, flotation process. Gravity processing is the most leaching methods in gravel gold mining. Flotation is mostly used in rock gold. There are also cyaniding, leaching, micro-leaching and all slime cyanidation. ... [more]
