The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …
Bentonite often contain a small amount of illite, kaolinite, halloysite, chlorite, zeolite, quartz, feldspar, calcite, etc. Some bentonites are as loose as soil, and some are dense and hard. The main chemical components are silicon dioxide, aluminum oxide and water, and also contain iron, magnesium, calcium, sodium, potassium and other elements.

A duplex unit is necessary to provide the ...
Uses: Feldspar is used to make dinnerware and bathroom and building tiles. In ceramics and glass production, feldspar is used as a flux. Flux is a material that lowers the melting temperature of another material, in this case, glass. Feldspar can be replaced by other minerals and mineral mixtures of similar physical properties.
Then the fine clay impurities under 200 mesh are removed through hydrocyclone and spiral classifier. The minerals between -20 mesh and -200 mesh are sent to flotation workshop. • Feldspar flotation: …

Introduction: Sand washing machine is widely used for washing materials in industries such as gravel yard, mining, building materials, transportation, chemical industry, water conservancy and hydropower, and concrete mixing station.Spiral sand washer and wheel sand washer are two common sand washing equipments, which can be used for …
Gravity separation is an important mineral recovery method. According to the difference in density between minerals, the gravity, fluid power or mechanical force in the moving medium is different, to realize the process of separating mineral particles according to density. The main gravity beneficiation equipment is jig concentrator, shaking ...
High dam spiral classifier. In high dam spiral classifier, the position of overflow dam is usually higher than the bearing center at the lower end of the spiral shaft and lower than the upper edge of the spiral at the overflow end. The height of dam can also be adjusted within a certain range, that is, the area of settlement area can be ...
Overview . Introduction: The gold centrifugal concentrator rotates at a high speed, generating a high "G" force, which can separate small gravity recovery gold (less than 50 microns). The centrifugal concentrator can also recover the tailings of gold, chromite, scheelite and other heavy minerals. So as to make better use of the mineral ...
Zircon sand processing plant is the process of removing impurities from zircon ores and increasing zircon content. Zircon (also known as zirconium)is zirconium orthosilicate. Its chemical formula is ZrSiO4.It is one of the most common zirconium-bearing minerals. The zircon ore deposits are mostly seashore placer deposits.
