The Fujian sand making project made by SANDMINE recently has been successfully put into trial operation after busy installation and commissioning. After the successful trial operation of the high quality sand making project, it shows a high sand ratio. Through the mechanism of sand grading after adjustment, it reduces the gap rate between the aggregate, reduces the amount of cement and improves the compactness and durability of the concrete. It also reduces the sand comprehensive production cost which causes the huge radiation and attracts a lot of visitors and good review.

　　SANDMINE uses particle gradation adjustment technology to solve the problem of large size and small size in the two parts of traditional mechanism sand gradation. It controls the distribution of particle size at all levels well, so that the accumulated sieve residue at all levels meets the requirements of national standard, and meets the needs of all kinds of concrete and dry mixed mortar. The sand making machine adjusted by gradation can reduce the void ratio between the aggregate, reduce the amount of cement, and improve the compactness and durability of concrete.

　　1. It is adapted to a wide range of applications and various functions

　　It can be processed for construction waste, stone debris, mine waste stone, cobblestone and various hardness rocks. The maximum particle size before crushing is 600mm.

　　2. The production capacity is large and the quality of output is high

　　The maximum feeding capacity of the sand and stone is 500t/h, and the maximum feeding capacity of the pure sand making station is 200t/h.

　　3. Intelligent control, safety production

　　4. Convenient maintenance.

　　5. The moisture content of raw materials and the range of mud content are widely adapted.

　　Moisture content, clay content is less than 10%. (with special water and mud remove system)
