Mill Crusher Limestone Concrete Granite Hard Stone Crusher Main Motor Power 355-450kw

Higher output

The design of large eccentric distance and high oscillation frequency can make the equipment operate at lower speed, and the product gradation can be changed to produce less fines, which brings higher output and larger crushing ratio.

Better Quality

HPM series cone crusher adopts the principle of laminar crushing, which makes the product size uniform and the grain shape square, and improves the product quality.

Intelligent control

Adopting Siemens PLC+touch screen intelligent automation control system and remote control system, which improves the safety factor of equipment operation and makes the operation more simple and convenient.

Easy maintenance

All parts of the mainframe can be disassembled from the top or side, which makes the operation more convenient and efficient, saves labor and time, and lowers the maintenance cost.

Working principle

Cone crusher consist of frame, transmission device( countershaft, countershaft bushing, gear and pinion), main shaft, eccentric shaft, cone,mantle, bowl-shaped bearing, springs and hydraulic pressure station for adjusting discharge opening.

(1) Transmission device: Countershaft assembly is supported by the bronze countershatf bushings, can be dismounted for convenience of maintence. And the gear and pinipn with high strengh and high precision are adopted to ensure the reliable operation of equipment.

(2) Main shaft: Forged form hardened and tempered chrome molybdenum steel particularly large diameter to suit wear-resisting application. High quality copper socket liner can bear high crushing load, and allows the machine working under rigorous condition.

(3) Cone and mantle plate, high manganese steel casting, hydraulic lock device is convenient and reliable.

(4) Spring and hydraulic device: Convenient for adjusting the discharge size, can remove the foreign materials if non-crushable objects came into the crushing chamber.
