As coarse crushing equipment, jaw crusher is widely used in fields such as crushing, grinding, dressing, etc. Jaw crusher works by virtue of the motion of eccentric shaft driven by electric belt in electric motor. There are certain disadvantages about the on-link mode between belt pulley and eccentric shaft. Due to the transition fit adopted by this conical fit, only by heating equipment or pressure device can the assembly and disassembly be realized in routine work. This kind of construction and device goes against the work, such as routine maintenance and overhaul work, assembly and disassembly work, etc. Consequently, Henan Hongxing Machinery developed two new plans through design, research and improvement. The major purpose is to optimize jaw crusher structure and save the material consumption. The improved jaw crusher is simpler and more practical in structure and more convenient in maintenance, therefore, products have been endorsed unanimously by the broad mass of customers.

The expansion-joints mode has been adopted in the link between belt pulley and eccentric shaft for improved jaw crusher. The bore design of belt pulley adopts cylindrical bore in order to coordinate the on-link mode between expansion sleeve and eccentric shaft. The expansion sleeve on-link mode is a new type link mode in jaw crusher structure.

The taper bore has been adopted in improved jaw crusher in order to coordinate the on-link mode between taper bore and eccentric shaft.

The above mentioned is the improvement of jaw crusher from Hongxing experts. The improved jaw crusher is simpler and more reasonable in structure design and plays a better crushing role.
