How does the traditional shaped sand and gravel equipment evolve into fine sand and gravel aggregate sand making equipment? The technicians have adjusted its local structure, such as changing the traditional blower design, forming a special airflow self-circulation system in the vortex cavity inside the crushing cavity, reducing the external exhaust of the sand making machine and effectively improving the natural dust overflow; meanwhile, strengthening the sealing device of the dust source (inlet and outlet) and installing the dust removal fan to control the dust diffusion to ensure a sand making environment with less dust, low noise and green.

Besides the environmental protection effect, the fine sand aggregate sand making equipment also has good performance in some other places.

(1) Under the same power and operating environment, the sand production of environmental protection sand and gravel equipment can reach 1-2 times of ordinary sand making equipment, and the operation is stable.

(2)The fine sand and gravel equipment has uniform particle size and reasonable grading, and the natural sand and sand produced by the fine sand and gravel equipment is more in line with the construction requirements than ordinary hammer sanders, which can improve the construction quality.

(3)The important parts of fine aggregate equipment are made of materials with good wear resistance, which can greatly improve the wear resistance of the equipment, thus reducing the number of parts replacement and lowering the operating cost of the equipment.

The quotation of fine sand making equipment for general use sand aggregate ranges from several hundred thousand to millions of dollars, which is related to the manufacturer and type of equipment. Different manufacturers and different models of sand making machine have differences in various technical parameters such as feeding/discharging, motor power, etc. The effect achieved is also different, which is the reason why the quotation of sand making machine equipment is not the same.
