Performance
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.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 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.
6.HGT Gyratory Crusher has a heavy-duty framework, an integrated large-dimension axis and high-precision bearings, so, undoubtedly, it has higher strength and longer service life, allowing it to work continuously and safely under high intensity. The heavy-duty framework can adapt any severe working situation while the integrally-forged axis and moving cone eliminate the risks that the cone gets loose during operation, which further shortens the downtime.
Working Principle
HGT Hydraulic Gyratory Crusher consists of beam, upper frame, middle frame, lower frame, moving cone, eccentric sleeve, transmission part and hydraulic cylinder part. Driven by the motor, the horizontal shaft starts to rotate which then further makes the eccentric sleeve rotate under the assistance of gear. Next, the eccentric sleeve drives the moving cone to swing in a circular motion to squeeze and crush rocks continuously.Adjusting the hydraulic cylinder on the bottom of moving cone to let the cone move up and down can make the adjustment of the discharge port's opening easier, and, therefore, the granularity of final products can get better control. Besides, the hydraulic cylinder has a protection function when iron blocks intrude. If there are unbreakable materials such as iron blocks entering the crushing cavity, the hydraulic cylinder will drop the moving cone to release iron blocks while the crushing process doesn't stop.
