DG Series Hydraulic Cone Crusher

DG series single-cylinder hydraulic cone crusher is widely applied in industries, such as metal and non-metallic mineral, building materials, transportation engineering, metallurgy and ;hydraulic engineering; it can be used for intermediate and fine crushing of all kinds of mineral, such as iron ore, non-ferrous metal ores, granite, limestone, quartzite, sandstone, cobble and so on. ;DG series single-cylinder hydraulic cone crusher has a combination of crushing machinery, hydraulic, electrical, automation and intelligent control technology. The machine is the high efficient crusher which is researched and developed independently by our company based on 20 years of experience on design, production, sales and service, combined the development of modern industrial technology, and has widely absorbed advanced crusher technology of the United States and Germany. This machine represents the world's most advanced technology and has many incomparable advantages such as high efficiency, low...


DG series single-cylinder hydraulic cone crusher is mainly composed of upper bracket, middle bracket, bottom bracket, movable cone, eccentric sleeve, transmission and hydraulic cylinder. The whole working process of this machine is that motor drives rotation of horizontal axis, horizontal axis drives the rotation of eccentric sleeve through the spiral bevel gear, and then eccentric sleeve would drive the rotary oscillation of movable cone so as to realize the continuous extrusion.  
The adjustment of hydraulic cylinder at the bottom of movable cone can drive main shaft thus driving movable cone move up and down to easily adjust the space of movable cone and the lining plate of fixed cone, then the product size will be controlled. Hydraulic cylinder also has the function of overload protection. When materials that cannot be crushed (such as iron) enter into crushing chamber, the accumulator will be triggered, then the hydraulic cylinder will drop movable cone to release the iron and recover normal crushing automatically, which can protect the crusher perfectly.

1.Simple structure and reliable performance. DG series single-cylinder hydraulic cone crusher integrates discharge opening adjustment and overload protection functions as a whole, which simplifies the structure and enhances the reliability. All different sizes have different cavity types to meet different crushing requirements. All maintenances are processed from the upper part, which makes maintenance more convenient.
2.Good product shapes and large production capacity. The machine adopts the principle of laminating crushing, which improves product shape to be cubic. The reasonable coordination of eccentricity, cavity shape and parameters greatly improves the production capacity and efficiency of the equipment.  
3.Advanced control system brings precision control. Full automatic control system provides various operation modes, such as manual control, constant discharge opening control and constant power control. Automatic monitoring system can help to know the equipment operation situation at any time, which is in favor of playing the best performance of this equipment.
4.Optimized designed structure brings long service life. Sliding bearing adopts special oil wedge design, which can avoid direct frictional contact between shaft and bearing. Reinforced frame structure and special bearing materials have large carrying capacity and high reliability, which can extend the service life of this equipment.
5.Hydraulic lubrication station makes low operation cost. The integrated design of hydraulic pressure station and lubricating station save installation space. Optimized components layout and tank volume can make operation and maintenance simple and decrease operating cost.
