If refined textured sand is selected, a new filter element needs to be built to make the quartz sand evenly distributed, which can effectively prevent surface blocking and reasonably filter stains. If the setting is effective, it can also filter to standard materials at one time. If the setting is effective and the layout is reasonable, it can generally give full play to its relatively large green energy. Generally, 15-20 meters are filtered every hour, And try to control it within 50 hours. For the use of quartz sand, the actual effect of very balanced particle size distribution is naturally more ideal. The larger the particle size, the easier it is to clean. If there are fine particles, they should be cleaned continuously, and then repeatedly cleaned with air and water. The actual effect of water cleaning can be improved by using the friction force and impact force between particles.

Particle appearance: Due to the difference in production equipment, original ore origin and crystal structure, heavy calcium carbonate is usually divided into various particle shapes, such as multi-faceted body, flat flat body, rectangle, long rod, near round ball and irregular shape. In many aspects, the rectangular calcium carbonate has good circulation in the processing of plastic products, which is convenient for silane coupling agent to cover chemical crosslinking, and the production equipment is less damaged, but the physical properties of the product are relatively reduced; The specific surface area of flat flat and long rod particles is relatively large. If surface treatment is carried out, the silane coupling dose will be increased, but the physical properties of the product are good.

There are three key types of calcium carbonate: high quality calcium carbonate and light quality calcium carbonate. Heavy calcium carbonate is produced by crushing natural dolomite, limestone, limestone, pearl shell, etc. immediately with equipment. Light calcium, also known as sedimentary calcium carbonate, is produced by calcining raw materials such as dolomite to produce lime powder, adding water to digest and absorb lime powder to form mature lime, and then filling carbon dioxide to carbonize and deposit, which is dried, dried and crushed. Or, first, dilute hydrochloric acid and calcium chloride are used to carry out the double decomposition reaction to form calcium carbonate deposits, and then they are prepared by dehydration, drying and crushing. Because the production method is different, light calcium has a large deposition volume and looks light. In fact, the relative density of the two is not very different.

The scratch hardness of quartz sand filter material is also called Mohs hardness tester. Mainly used for hardness and softness of different minerals. The method is to first select a component with one hard end and one soft end, then cross the tested material along the component, and determine the hardness and flexibility of the tested material according to the length of the scratch. In terms of quality, hard objects have long scratches and soft objects have short scratches. Hardness of quartz sand filter material. Mainly used in metal materials and quartz sand materials. The method is to put the tension of the specification into the tested material at the load effect, and compare the hardness and softness of the tested material with the partial plastic deformation of the material surface.

Generally speaking, there are three methods of iron removal: mechanical equipment scrubbing, magnetic separation equipment and ultrasonic wave. The iron removal by mechanical equipment scrubbing is mainly to remove the iron residue outside the raw quartz ore through the actual effect of external force. Mechanical equipment scrubbing also includes rod scrubbing and mechanical equipment scrubbing. When mechanical equipment is used for iron removal, some aqueous solutions are required to cooperate with each other, and the concentration of coal slurry is set to a certain ratio to conduct iron removal and carding of raw ore quartz sand. However, this kind of iron removal method is only applicable to some manufacturers with small output, and the quality of raw quartz sand may be very good.
