The sand making machine integrates three crushing modes, acan continuously work for 720 hours. Higher crushing chamber, greater crushing impact. During the parts and material procurement, production and processing, the quality is strictly controlled. Wearing parts is optimally allocated for longer service life. Hydraulic autonomous system performance, low failure rate. The whole frame adopts elastic reinforcement technology, eliminating the problems like easy fracture of the motor frame.
 
Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards.
After hitting each other, they force a vortex between impellor and shell, and hit each other several times; finally smaller stone comes out, and goes to vibrating screen.
Satisfactory material is transported to sand washing machine; however overlarge material will go back to sand maker to be recrushed.
Output sizes can be made According to customers requirements. If input size is larger than the designed size, other crushing equipment will be Necessary.
 
Rotor design of deep-cavity is optimized and then the amount of materials is Increased bv 30%
Round guard plate can have a U-turn after partially wearing usage, Thus to improve material utilization.
Special sealing structure in the bottom of the spindle to the Ensure no sealing and leaking oil.
