3. A finished product granularity less than 5mm,account for 85%.

4.Product grain type is excellent, a cube, the needle flake content is extremely low, appropriate aggregate plastic, artificial system sand and high grade highway of stone specifications take; Stacking density is big, iron pollution minimum.

5.Too less Working noise and dust pollution.

6.In the old third create sand machine based on the increased weight wheel, so that the energy can be saved, increased the kinetic energy. Production efficiency has been greatly improved.

7.In the third create sand machine back opened maintenance observation door. It is more advantageous to the maintenance and observation equipment operation condition, and increased the article labyrinth control device, convenient adjustment of the sand the grain-size.. A design more humanized.

PXJ Sand Making Machine crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.
