Gypsum Washing Unit for Sale
The vacuum belt filters that can be used to filter and wash the gypsum. The filtration cycle begins when vacuum is applied to the slurry that has been distributed on the vacuum belt filters. There are two distinct operations in the filtration cycle: cake formation and cake dewatering.
Cake formation occurs as the free water is removed from the slurry. The end of the cake formation portion of the cycle is visually noted by the free water disappearing from the surface of the cake.
The cake formation occurs very quickly after vacuum is applied. The cake wash water displaces dissolved contaminants from the formed cake. Cake wash water may be either recycled cloth wash water or makeup water. After cake formation and cake washing, cake dewatering begins and continues through the remainder of the cycle.
Gypsum Washing Application
Washing is the simplest and lowest cost method of cleaning gypsum. In some of the very pure deposits that are void of heavy minerals, high amounts of clay and silt, and no surface staining, washing is sufficient to produce acceptable grade product.
In the process, water is added to the sand and is generally pumped to a cyclone for desliming. The movement of the slurry passing through the pump and pipeline is sufficient to loosen the small amount of fines or clay that are in the ore body. Once the minor amounts of fines or clay have been released from the silica sand they can be removed via a variety of methods.
Gypsum Manufacturing Plant
Gypsum processing plants vary widely in scale and level of technology. They range from plants producing one or two tonnes per day using low-cost manual technologies, to plants of a thousand tonnes per day that are highly mechanized and capable of producing different types and grades of gypsum plaster or plaster board.
There are several basic stages in gypsum processing: excavation is the first stage, it is generally carried out by digging out an area of ground where the gypsum is
located using open-cast techniques. The following techniques are crushing, screening, grinding and heating. SBM provide high quality gypsum manufacturing plant and gypsum washing unit for sale.
