The company is a local large sand and gravel plant in Henan province, which is mainly engaged in processing and selling all kinds of sand and gravel. Due to production development needs, they need to purchase a high quality mechanism 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 blue stone sand making production line.

First, the bluestone is firstly crushed by the jaw crusher for preliminary crushing. Then, the coarse material produced is conveyed by conveyor to the impact crusher for further crushing. The finely crushed bluestone material enters the vibrating screen to screen out two kinds of stones, and the material that meets the feeding size of the sand making machine goes into the bluestone sand making machine to make sand, and the other part of the returned material goes into the impact crusher to be crushed again. Part of the stone into the sand making machine into the sand, the other part into the sand making machine again crushing, and finally the finished product.

1.Good granularity of finished products: the product granularity is cubic in shape, excellent quality, low content of needle and flake products, strong resistance to compression, suitable for high standard construction needs. 2: Wide application of raw materials. 3: Customized program, more productive. 4: The whole production line of high degree of automation, low cost, crushing efficiency change, small pollution, good energy saving, low failure rate.
