The sand making machine integrates three crushing modes, and cancontinuously work for 720 hours. Higher crushing chamber, greatercrushing impact. During the parts and material procurement, productionand processing, the quality is strictly controlled. Wearing parts isoptimally allocated for longer service life.

Hydraulic autonomoussystem: Convenient maintenance, high performance, low failure rate. Thewhole frame adopts elastic reinforcement technology, eliminating theproblems like easy fracture of motor frame.

Working principle:
Stoneis crushed by hitting other stones. Material falls down to impellorcavity. Under great centrifugal force, it hits material that comingdownwards. After hitting each other, they force a vortex betweenimpellor and shell, and hit each other several tomes; Finally smallerstone comes out, and goes to vibrating screen. Satisfactory material istransported to sand washing machine; However overlarge material will goback to sand maker to be recrushed. Output sizes can be made accoding tocustomers requirement. If input size is largeer than the designed size,other crushing equipment will be necessary.

Advantages and Features:
Rotor design of deep-cavity is optimized then the amount of matgerials is increased by 30%.
Round guard plate can have a U-turn after partially wearing, thus to improve material utilization.
Special sealing structure in the bottom of the spindle to ensure no oil sealing and leaking.
