The enterprise is mainly engaged in limestone, marble, granite, waste material, quarrying, processing and sales. Due to the development of production, 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 limestone sand production line.

Through the impact of the centrifugal force generated by the high speed rotation of the vertical shaft impeller of the crusher and the surrounding height and other airflow high speed impact on the material part of each crushing impeller on other materials, they will form a vortex with the impeller and shell on the material for multiple impacts, friction and grinding, and from the bottom of the vertical shaft sand making machine, through the closed loop control of several projection equipment to form a direct discharge, so as to achieve the specified finished product size.

1: Adopted new design structure, which effectively enhances the crushing performance and improves the production efficiency of the equipment. 2:Combined structure design is adopted, which is more conducive to hammering and crushing materials, greatly extending the service life of hammer head, thus effectively reducing the production cost and the impact of equipment downtime. 3: Compact structure, light weight, small size. 4: Good sealing performance, avoiding the splashing of small pieces of materials after crushing, less dust, low working noise, effectively improving the working environment of the construction site.
