High-purity quartz sand tailings process The treatment of quartz sand tailings should follow the basic process of crushing, roughing, calcining, water quenching, grinding, magnetic separation, pickling, cleaning and drying. The crushed quartz sand tailings are roughed to remove obvious impurities, and then mixed with sodium oxide solids for calcination. After calcination, the quartz sand is showered and quenched to crack the quartz sand and remove the normal sodium silicate on the surface. The quartz sand tailings are then pulverized using the ball mill equipment using a wet grinding process, followed by magnetic separation, pickling, cleaning, and drying in sequence. The treatment of high-purity quartz sand tailings is actually based on the basic process of quartz sand purification, combined with the characteristics of quartz sand tailings itself, the purification production process has been adjusted, and the purification of quartz sand tailings has been better realized. Increase its ...

Drum screen is a special screening equipment developed for building materials, metallurgy, chemical industry, mining and other industries. It overcomes the clogging problem of circular vibrating screen and linear vibrating screen when screening wet materials, and improves the output of the screening system. And reliability, it is widely used in the separation of sand and gravel in the sand and gravel field, as well as the size and particle size classification and lump powder separation in the chemical industry and mineral processing industry, and is favored by customers. 1. The noise problem caused by the loosening of equipment bolts Solution: Retighten bolts or other fasteners; 2. The wrong direction of rotation caused by the wrong connection of the motor power cable Solution: replace the power cable in the junction box; 3. The problem of delay in starting the click caused by overload of the motor or excessive conveying capacity Solution: readjust the delivery volume; 4. Insufficien...

 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.

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

Emery is a kind of artificially synthesized silicon carbide, which has good thermal conductivity, stability and wear resistance, so it is widely used in metallurgy, building materials, ceramics and steel industries. How much do you know about its production process? Here is a detailed summary for you: ⑴, raw material crushing Hammer crusher is used to crush petroleum coke to the particle size required by the process. ⑵, ingredients and mixing Batching and mixing is the process of weighing and mixing according to the prescribed formula. The platform is used for batching, and the concrete mixer is used for mixing. The batching and mixing operations of petroleum coke and quartz sand are carried out according to the process requirements. ⑶, silicon carbide electric furnace preparation Electric furnace preparation is to refurbish and reorganize the furnace that was used last time, so as to put it into use again. The work content includes cleaning the bottom material of the furnace, repairi...

In the eastern coastal areas of my country, the population is dense, the economy is developed, and the amount of engineering construction is large. When the supply of river sand resources is insufficient, there is no other sand source to replace (for example, mountain sand or machine-made sand can be used in inland areas), and long-distance Transporting river sand will greatly increase the project cost. Like many foreign countries, in the case of shortage of land sand resources, people began to turn their attention to the local sand source—sea sand. Therefore, the mining and utilization of sea sand in coastal areas is a need for economic development. The United Kingdom, Denmark, Norway, Sweden, Belgium, Canada, Australia, New Zealand, Japan, South Korea, Turkey, India and other countries, as well as my country’s Taiwan region, have many years of history and rich application experience in sea sand application in engineering construction. . In particular, Japan, which is short of river s...
