  Purification of silica sand The process of cleaning silica sand is crushing, washing/, magnetic separation, acid leaching, washing, dehydration, and drying. water washing Washing sand recycling machine working principle.  After the natural silica sand is classified and filtered by the screening equipment, the qualified products flow into the spiral sand washing machine through the launder or the pipeline. It is fully cleaned, soaked and broken by a screw mixer (for larger muddy and extra-large effect), sandstone is fully separated from impurities and mud. Fine sand and muddy water are deposited in the tail of the spiral washing, and the recovery of fine sand is achieved through a concentration and recovery device. Then the coarse and fine sand enters the wheel washing machine at the same time for secondary cleaning to achieve complete separation of the sediment. Silica Sand Attrition Scrubber Scrub With the help of mechanical force and the grinding and peeling force between ...

The annual output of 1 million tons belongs to the medium scale.

Because kaolin is easy to disperse and suspend in water, the screening process of kaolin vibrating screen is wet screening. First, the kaolin ore is made into a slurry of micron-level or smaller unit particles, and a dispersant is appropriately added to make the minerals in the water. Dissociation, so that the high collar stone and impurity minerals in the kaolin will be divided into three different grades of fine, medium and coarse, and then the pure kaolin ore will be sieved out through the grading action of the vibrating screen. This series dewatering screen output lower water content kaolin, hot sell in the market. LZZG use PU screen as its new type sand washer sieve, because its long service life and not easily blocked in screening. When processing coal mud or dirt mixed water, steel mesh is easily blocked and adjusting its mesh size will highly reduce its capacity.

Tailings are “waste” discharged by mining companies under certain technical and economic conditions, but at the same time they are potential secondary resources. When technical and economic conditions permit, they can be effectively developed again. What equipment is needed to make sand from tailings The waste rock chips from different sources have different lithologies, different mining and crushing processes, and have very different physical properties. At present, there is insufficient systematic research on the performance of rock chips, and the law of the quality of rock chips and their impact on concrete performance is mastered. insufficient. The low-quality stone chips have large powder content, rough surface, sharp edges and corners, difficult mud removal and shaping technology, and large investment; the problem of mud removal and shaping is not solved, and it is not conducive to the convenience of concrete, increasing the amount of cement, poor market acceptance. ...

There is many tailings dry stacking process. In order to solve the problem of tailings dehydration, the concentration (concentrator or cyclone) + filter or filter press system was commonly used in the past, but there is a large area, large investment, high power consumption, and use cost Higher issues. In recent years, a new tailings treatment process that has gradually emerged in China refers to the concentration of the tailings slurry output by the beneficiation process, and then processed by the dehydration vibrating screen equipment. The water content of the product on the screen is usually below 20% and can be directly transferred Go to a fixed location for dry storage.

kaolin washing process The sand is first removed by a spiral classifier. It is then entered into a hydrocyclone for classification. The sorted coarse concentrate enters a horizontal spiral centrifugal classifier to separate the paint grade and filler grade kaolin. The raw ore is added with water and dispersant according to the set concentration requirements, and is made into pulp in a blender or tamping machine. The purpose of pulping is to disperse kaolin and separate it from sandy minerals and plant impurities, so as to prepare a slurry of suitable concentration for the next process. Screw classifier to remove coarse sand In the raw kaolin ore, the particle size of quartz, feldspar, mica and other impurities is coarse, generally larger than 325 mesh, and the particle size of kaolin is fine, mainly concentrated in -2μm. The spiral classifier can remove most of the quartz and feldspar coarse sand. Use hydrocyclone to sort the kaolin The hydrocyclone is used for sor...
