Zhengzhou dehong Machine Manufacturing Co., Ltd , taking high efficiency\energy saving\high productivity\and low energy consumption\as the core design of new sand productionline.

Jaw crusher:
The crusher roller rolls positive and negative direction, to makethe material broken more effectively; And also added a symmetrical vice cavity, shorten the crush process spare travel, thus the production can increase 30 percent to 40 percent. In the PSH series gyratory crushers, the broken roller of the rotary crusher adopt high strength wear-resistingweld layer, canbroken materials with compressive strength 600 MPa, as for Al2O3,87.5% beingthe refractory materials, can be easily broken.

Double-acting jaw crusher:

The former Shanghai building materials industry college usingthe" fixedvolume " principle:elicit aunique ideas correction gaussian curve equation. Using this equation they designed new generation of PEX-150 X50--A ,the type of advancedjaw crusher. Cavity of this equipment is the type of advanced crushing cavity" linear-spin round line-the gaussian curve"type of . This requires thedevice itself should have good self protection system, to make equipment to operate safely,and have a low failure rate.
