1.Strong crushing capacity and low cost
The crushing chamber with large obliquity and long crushing surface make crushing machine possess of higher capacity and scaleboard possess of long service life. Super heavy type frame, large diameter integral spindle assembly and high performance bearing ensure longer service life and safer operation.

2.Hydraulic control system makes adjustment and control easy
The adjusting system of mine drainage outlet adopts hydraulic adjusting method to compensate for wear liner. It can adjust the spindle easily to compensate for liner wear and control product size.

3.Automatic control system makes maintenance convenient
It adopts automatic lubrication heating, cooling and circulation system, automatic spindle position control system and convenient tooth space external adjustment device. Besides, there is a hydraulic beam separator used for beams disassembly during operation.

4.The design of heavy duty spindle makes service life longer
The design of integral forging spindle avoids the danger caused by loose moving cone, so that it can reduce the downtime. The spindle neck and pyramidal transitional part adopt large radius arc and polish, which increases the strength of spindle and extends the service life.

5.High quality materials makes crushing performance better
High strength frame design makes machine work in different working environment even the condition is poor. The effective dustproof seal device is equipped with positive pressure blower, which prevents the dust to enter eccentric device and drive device. And it can help bearing’s service life longer.
