There are various types of sand washer, mainly used to clean artificial sand (including natural sand) washing equipment. Sand washing machines are mainly used in quarries, chemicals, construction materials, mining, water conservancy, and hydropower, concrete mixing plants, and other industries. The stone washing machine is mainly used to remove the impurities (such as dust) attached to the sand products. Because it uses more water washing methods, it is called a sand washing machine. Classification of the sand washing machine: spiral sand washing machine, drum sand washing machine, water wheel sand washing machine, vibration sand washing machine, etc. Different names are distinguished according to their unusual appearance and principles. The sand washing machine can remove impurities covering the surface of sand and stone, and at the same time destroys the water vapor layer covering the sand, thereby promoting dehydration and effectively washing and cleaning sand.
So what is the working principle of the sand washing machine?
When the sand washer is working, the motor reduces the speed through the triangle belt, reducer, and gear to drive the impeller to rotate slowly. The sand and gravel enter the sink from the feed trough, rolls with the impeller rolling under the impeller, grinds each other to remove the impurity on the sand gravel surface, destroys the water vapor layer on the sand gravel, and achieves the effect of dehydration. At the same time, water is in addition to the sand washing machine to form a strong water flow, and the prevailing water flow drains the impurities and foreign bodies with small specific gravity from the overflow tank to achieve the cleaning effect. Clean sand and gravel are poured into the discharge tank as the blade rotates, and then the gravel is cleaned.
1. The structure of the sand washing machine is simple, and the impeller drive bearing device is isolated from water and materials, which greatly prevents damage to the bearings by water, sand, and pollutants.
2. Compared with the traditional sand washing machine, the sand washing machine contains the following obvious advantages.
(1) The loss of fine sand and stone powder is minimal. And the grade and fineness modulus of washing building sand reaches the standard.
(2) The sand washing machine is difficult to be damaged. And it is relatively robust. Except for the screen, there are almost no vulnerable parts.
(3) It has a long service life. If it is used for a long time, it will not be a malfunction or repair.
3. It has the characteristics of reasonable structure, convenient mechanical maintenance, large working capacity, small power consumption, high material cleaning degree, novel sealing structure, adjustable overflow Weir plate, full block oil bath transmission device, which ensures the high efficiency, durability, cleaning effect and good dehydration effect of the series products.
4. It is mainly used in construction sites, hydropower stations, gravel plants, glass factories, and other units. The work consists of washing, grade and stone, grading, and dehydration.
