The Domestic Production Status of Mechanisms Sand

The quality of the mechanisms sand largely depends on the physical properties of the parent rock, processing, machinery equipment and other factors. The main raw materials for the production of the mechanisms sand include the limestone, dolomite, granite and basalt.
The domestic sand and stone plant is mainly the small gravel plant with less than 50t / h and the production process is simple. The production output of the gravel plants with certain scale is 100t/h to of 200t / h. The two-stage crushing and sieve are mainly used to constitute a closed process job. At present, the problems existing in the mechanism sand industry in China are the followings.
First, there are no professional design concepts and the equipment selection is irrational. The production technology is backward and the production scale is small. In addition, the production of the mechanism sand has serious damage to the environment.
The modern sand production process and equipment of the mechanism is established on the full grasp of the characteristics of the rock material properties and performance of the terminal products to select the appropriate production equipment with organic combination, clear division of labor and mutual matching. However, the production status of mechanisms sand in China is not going well. On one hand, we are lack of professional sand production designer. Most of the researches focus on the characteristics of the mechanism sand and preparation and performance of the mechanisms sand concrete. Therefore, the research of the preparation technology, equipment, process of the mechanism sand is neglected. On the other hand, the production operators think that the sand, stone production technology is simple without professional design. Furthermore, some equipment manufacturers ballyhoo and promote some simple crushing and screening equipment to the market with new names, which is bond to cause of the disqualification of the mechanism sand. The use of the singe-stage jaw breaker and small hammer sand maker goes against the production of the mechanism sand.  
Second, the technological literacy is low and the quality awareness is poor withconfused management.
Most of the practitioners in domestic sand and stone industry has no technical training and their technical literacy is low. They do not how to use and maintain the advanced equipment and process. At the same time, they are lack of the understanding and knowledge of the mechanisms sand technology requirements and they have no concepts of gradation, fineness modulus, the powder content and clay content.
