Strength similar to mortar made of quartz sand. So river sand in general construction, decoration has an irreplaceable role!
Sand making equipment
Sand production line is mainly composed of vibrating feeder, jaw crusher, impact crusher, vibrating screen and belt conveyor.
Sand production line
(1) Large stone by silo by vibrating feeder evenly sent to the jaw crusher are crushed, crushed stone to the crusher for further crushing by belt conveyor;
(2) After crushing stones by belt conveyor sent to the sieve screening, screening gives several different specifications of stones, meet the requirements of the stones size by finished belt conveyor to finished material pile;
(3) The stone which does not meet the granularity requirement is sent back to the impact crusher by the belt conveyor to be broken again to form a closed circuit multiple cycle.
