The effect of the backwash water pressure on the Classifying Equipment of the material is reflected in the selective barrier mechanism for the different particle size materials. During the test, the backwash water pressure varies from 0 kPa to 35 kPa, the other conditions: the ore concentration is 10%, the feed pressure is 72 kPa, the underflow pressure was 55 kPa, and the overflow pressure was 50 kPa.

The test results for different backwash water pressures can be seen, when the backwash water pressure increases, the grading efficiency of each particle size tends to decrease. When the recoil water pressure is greater than 5kPa, the grading efficiency of each grain grade is rapidly reduced, which is not conducive to grading. The results showed that the appropriate backwash water pressure is beneficial to improve the efficiency of coarse particle classification by CLA. The best pressure in the test is 5kPa.

Sand filters are used as a step in the water treatment process of water purification.

There are three main types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters. All three methods are used extensively in the water industry throughout the world. The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high quality water free from pathogens, taste and odour without the need for chemical aids. Sand filters can, apart from being used in water treatment plants, be used for water purification in singular households as they use materials which are available for most people.

The best benefits of modern enterprises from the leading technology , which is reflected in the reasonable process and efficient energy-saving equipment. We must provide the reasonable process , choose the correct equipment configuration , not only the best quality and provide them with the most intimate housekeeping service, this is what we can do, also we should do.
