Gyratory Crushers

Description

Gyratory crushers are main equipments for crushing ores and rocks in mining, forging, constructing, chemical industry and power stations.They have high crushing rate, high output rate and their products have even grains.
We have more than 20 years history of designing and manufacturing gyratory crushers. Its products form series from PXZ-0405 to PXZ-1619. These products are welcomed by domestic and foreign customers for their variety of models, advanced design, reliable capacity, stable running and low consumption of energy.
We  produce three series of gyratory crushers. They are PXZ (heavy), PXQ (light), and PXF (introduced). PXZ series is used for crushing material of high or intermediate hardness and PXQ series is used for crushing material of intermediate or low hardness.
PXF is mainly used as coarse crushing equipments for large open mines and ore dressing plants. Gyratory crushers consist of transmitting assemblies,Bottom shell assemblies, eccentric sleeve assemblies, crushing head assemblies,middle shell assemblies, spider assemblies, motor assemblies, oil cylinder assemblies,pulley assemblies and grease and oil lubricatingsystems. The motor drives the eccentric by a horizontal shaft and a pair of conical gears while the crusher is running and force the axis of mantle to swing, therefore the opening of the upper mantle and the lower mantle changes in a certain range and the material is milled,bended and finally crushed. The crushed material is discharged by gravity.

Features of Product
·Highly intensive casting steel material is used, the safety coefficient is high, it can operate well even in the dreadful environment.
·The high intensive alloy is used for main shaft, the bush outside the main shaft is manganese steel, if the cone is wear, the bushcan be changed quickly.
· Hydraulic supporting Is used for overload protection and adjust discharge opening.
·Main shaft position indicator is used for check the position, and adjust discharge opening cooperate with the hydraulic system.
· Air Seal System can seal the eccentric sleeve, gear and pinion, and also air filter system can make sure the inside air without dust.
· Electric grease lubrication motor is used, it can lubricate the beam in certain time and automatic.
· Central lubrication system is used, it can lubricate the eccentric sleeve, gear, pinion and bear at the same time.
· The PLC is used, it is highly-automatized.
