| The Symons cone crusher appears earliest in the world, and is used widely at present. With the improvement of series of Symons cone crusher, Break-day corporation explores a PYS series of Symons cone crusher, its structure is more perfect and technology parameter is more advanced, so these crushers have excellent performance in the aspects of manufacture, installation, operation and maintenance, etc. And the spring release system generates more opposing force than other cone crushers. So it is widely used in mine industry.
Symons cone crusher technical parameter chart can be developed for use as an application tool to properly utilize the Symons cone crusher’s capabilities.
The Symons cone crusher is one component of the production line. As such, its performance is in part dependent on the proper selection and operation of feeders, conveyors, screens, supporting structure, electric motors, drive component and surge bins.
Where used, attention to the following factors will enhance Symons cone crusher capacity and performance.
1. Proper selection of crushing chamber for material to be crushed.
2. A feed grading containing proper distribution of the particle size.
3. Controlled feed rate.
4. Proper feed distribution 360° around crushing chamber.
5. Discharge conveyor sized to carry maximum crusher capacity.
6. Properly sized scalping and closed circuit screens.
7. Automation controls.
8. Adequate crusher discharge area.
After the material has slid down a short distance, the larger lumps or masses of the material are crushed into smaller masses by the impact created when these lumps are caught between the crushing head wall and the inner wall of the mantle jacket, as the head approaches a portion of the mantle wall.
When the head retracts after having delivered the impact, the material continues to slip down and spread out on the flaring wall of the head along a course bounded by the adjacent head and mantle walls, until another impact is delivered by the head. After each succeeding impact the crushed material becomes smaller and slides along and spreads out into an area of the tapered cavity having a smaller spacing between its walls.
The final size of the crushed product is determined by the spacing between the walls at the lower end of the crushing cavity, when the head is in its position closest to the mantle.
The size of the crushed product can be regulated by raising or lowering the mantle by means of the sprocket nuts, thereby increasing or decreasing the cross section of the crushing cavity.
