A branch of washing sand industry belongs to the machinery and equipment industry, also occupies an important position, because in recent years, the development speed of countries to accelerate the urbanization construction, the project is also more and more, aggregate demand will increase, thus constantly, sand washing machine is quite important.    In fact, the application of sand washing machine is very wide, for the upstream industry, the quality of functional components of the sand washing device determines the sand washing machine quality, for the downstream industry, sand washing machine for sand and river sand, artificial sand cleaning work is very important, is the social production of the necessary equipment.   Therefore the application widely degree is quite possible, although the downstream industry development directly affect the sand washing machine of the future, but with the gradual improvement of people"s life, is not only the construction industry on aggregate demand is big, the life of some of the basic construction of the facilities also need the participation of the future development of sand, so sand washing machine or very impressive, from the side can also be concluded that the future development direction of sand washing machine, is not just rely on technology to enhance the efficiency of sand washing machine, more important is the sand washing machine of the utility, the maximum expansion of the scope of its application, so as to better serve all walks of life, this is the future of wash the development direction of sand blasting equipment.
