Mining Primary Gyratory Crusher High Strength Design ISO9001 Certification

Stoneax primary gyratory crusher similar with Superior serise for chrome ore beneficiation plant

      Stoneax is the perfect partner for a complete stationary primary gyratory station solution. Stoneax has experience in the design and supply of primary gyratory stations made of either steel or concrete. Different locations favor one or the other with considerations

such as :

• Pit wall design

• Local costs of concrete works

• Site environmental conditions.

Stoneax designs with a focus on reliability and maintainability. As designer of the primary gyratory crusher we are in best position to design the entire crusher station for complete and safe maintenance access.

The spider and the top and bottom shells are made of shock-resisunt cast steel that provides the high strength-to-weight ratio necessary in primary crushing operations.

Working Principle

SG Hydraulic Gyratory Crusher is mainly composed of beam, frame, moving cone, eccentric sleeve, transmission part and hydraulic cylinder. Driven by the motor, the horizontal shaft starts to rotate which will further make the eccentric sleeve rotate under the assistance of gear. Next, the eccentric sleeve will drive moving cone to swing in a circular motion, so as to squeeze and crush rocks continuously.

By adjusting the hydraulic cylinder on the bottom of moving cone, the cone will move up and down to adjust the opening of discharge port so as to control the granularity of final products. Meanwhile, the hydraulic cylinder has a protection function when iron block intrudes. If there are unbreakable materials such as iron block entering the crushing cavity, the hydraulic cone crusher will drop the moving cone to discharge iron block while the crushing continues.

High-strength design provides reliable, trouble-free service

• The spider arms arc cast integrally with a heavy outer rim that is locked to the top shell through a machined interference taper fit, keeping the spider from coming loose and reducing maintenance requirements. The design of the spider increases the stability and rigidity of the top shell as well. The strong, bolted taper joints ensure assembly and increased reliability.When the spider is removed,the rim liners arc removed with it as one unit,reducing maintenance down-time for liner changes.

•  A sealed spider bearing cavity with a filtered breather prevents contami-nants from entering the bearing, reducing maintenance down-time and providing long life.

• A spider lubrication package provices timed, automatic lubrication of the spider bearing assembly, reducing maintenance.   

• An optional hydraulic spider separation system provides easy removal of the spider from the top shell. Jack bolts are standard.

• An optional top shell rotation system promotes even concave wear in mobile applications using a feeder.

• Circumferential ribs in the top and bottom shells provide the strength needed in a primary crushing application without adding unnecessary weight.    

• A spider lubrication package provides
