Basic Process of Mechanical Sand Production

Mechanical sand is manufactured by complete sand making plant. The system consists of vibrating feeder, jaw crusher, vertical shaft impact crusher, vibrating screen, sand washing machine, belt conveyor, concentrated electric control and other equipments. Designed production is generally 50-500 tons per hour. Kefid has been a leading manufacturer of sand making plant for around 22 years.

The whole set of sand making production line designed by Kefid can be used to process hard limestone, granite, basalt, river pebbles, smelter slag, and other materials, and is suitable for the application of hydroelectricity ,building, highway, city construction and other industries. We can deploy different plant to meet the customers ' different technological requirement.

Kefid mechanical sand production line has a high degree of automation, low operating cost, high crushing ratio, energy saving, great quantities, less pollution and simple maintenance. The produced mechanical sand can meet the national standard of construction sand. The sand has the quality of uniform size, good shape and reasonable distribution.

The complete sand making process as follows：
First of all, stone material should be crushed preliminarily by primary crusher, and then the crushed stones are conveyed to the secondary crusher with belt conveyor to next fine crushing. Fine stones are put into vibrating screen to sieve out two different kinds of material. The stone which can match the feed size of the Vertical Shaft Impact Crusher will be feed into the crusher, while the other part of the stone will be feed into the fine crusher for return crushing. Part of the stone that feed into the Vertical Shaft Impact Crusher will be made to sand, and it can be washed by the sand washing machine to make it perfect. The left will be recrushed by the crusher. the sand will be sieved by the vibrating screen and cleaned by the sand washing machine in the end, in order to get the sand that can meet the criterion.
