The company is a professional coal washing, mineral washing processing, coal products manufacturing, building block manufacturing, stone processing for construction, non-metallic waste and debris processing, renewable resources processing, coal and products sales, construction materials sales, renewable resources recycling enterprise in Inner Mongolia. Due to the development of production, they need to replace a sand production line. After many understanding and field investigation, they were attracted by Kolev's professional technology and excellent process, so they introduced our advanced equipment technology and purchased a full set of coal gangue sand production line.

First of all, the material falls vertically from the upper part of the machine into the high-speed rotating impeller, and then, under the action of high-speed centrifugal force, collides with another part of the material in the form of an umbrella shunt around the impeller. After that, in the strong vortex formed between the impeller and the casing, again or repeatedly impact, friction and crushing each other. Finally, it is discharged from the discharge port in the lower part of the granite sand making machine, and then controlled by the screening equipment to reach the required finished product size.

1: Simple and reasonable structure, reduce production cost through the improvement of hammer head. 2: High crushing efficiency, excellent and delicate granularity of the discharged material. 3: The finished product is a cubic in shape, with high packing density and low noise of equipment operation. 4: With a variety of models, it can be used for various types of sand production lines, and also can be customized according to customer needs.
