In recent years, because of the artificial sand and the increasing depletion of infrastructure construction carried out in full swing, with our rich stone resources for the production of artificial sand provides ample raw materials, mechanism of sand has become the building materials market a considerable profits for the blue chip stocks.
But as the market continues to heat up, some of the problems in the production will also appear, such as the backward production equipment, waste of resources, sand and gravel gradation does not meet the national standards, are the high speed development of sand and gravel industry has brought a lot of obstacles.
Compared with the developed countries, there are still some gaps in the technical level of domestic sand making machinery. In the domestic market, the sand making equipment is mainly VSI sand making machine, although the technology has been relatively mature, but there is still a low sand production rate, the feed port is small and so on. In the mechanism of sand production, the grain size can not be directly into the sand making machine, also need to be configured to fight back, broken and broken cone, etc., the process is not complicated, wearing parts loss and motor power loss is not a small expenditure. The German rotor centrifugal sand making machine production capacity can be increased by more than 1 times, feeding size 1 times, energy consumption reduced by more than 1, 50% times more than the rotor wear and tear, and patented dual chamber rotor design can achieve no jam.
Therefore, the domestic production of sand machine manufacturers to change the situation of domestic high-end sand production equipment, but also need to strengthen exchanges and learning with foreign advanced technology, and constantly improve their own R & D capabilities and sand machine equipment, scientific and technological added value.
