In recent years, the cone crusher uses the hydraulic technology and large rolling bearings to increase the crushing strength and vibration strength. The spindle is fixed. The eccentric sleeve is shifted up directly drive the cone to eliminate the gap between the eccentric sleeve and the straight set so that the crushing work is strengthened. The demarcated size of the discharge opening can reach 70% or 80%.

After entering the 21st century, a new generation of HP series hydraulic cone crusher uses the slow cone, large eccentricity, high shimmy, large crushing force, the surrounding multi-cylinder, hydraulic locking and spherical bush bearing structure. There are six types of the crushing chambers of the installation of the crusher from the coarse crushing to fine crushing. The fine crushing cavity uses the material layer crushing principle. The ore particles in the crushing cavity are squeezed and they suffer from strong grinding action. Therefore, a lot of fine powder is produced. The machine can reduce the maximum feed size. At the same time, it greatly changes the composition of feed size. 

 The new type of jaw breaker with moving jaw is produced by Henan Hongxing Mining Machinery. The motor drives the eccentric shaft through the V-belt. The rotation of the eccentric is driven to the movable jaw by the side plate so that the moving jaw can periodically swing. The materials that fall into the crushing chamber are crushed by squeezing, arm crack and bending. The materials after crushing are discharged through the discharge opening. The outer moving jaw is located outside of the crushing chamber, and its periodic motion helps feed and discharge. The moving jaw and the connecting rod is separated so that the rod movement no longer constrains the motion characteristics of the moving jaw. The trajectory of the moving jaw can be adjusted only by changing the institutional parameters to get the ideal motion characteristics for moving jaw. The horizontal direction of the moving jaw itinerary becomes large and the vertical direction of the stroke is small. The crushing chamber is in inclined state to reduce the height of the equipment. 

With the sustained and rapid development of the national economy, the demand for mineral resources and energy becomes more and more. As a result, the crushing equipment is more and more widely used in the iron ore plant. How to improve the level of rational utilization of mineral resources, save energy and reduce consumption is the priority.
