Fine Jaw Crusher Introduction

     Jaw crusher is suitable for crushing hard materials (compressive strength <250Mpa), such as: iron ore, slag, rock phosphate, copper ore, silicon ore, limestone, quartz, ceramics and its considerable hardness of solid materials in crushing operations, such as in a variety of block compound fine crushing plant, cement block compound fine crushing limestone, etc., with a crushing ratio, use and maintenance costs low, low power consumption, reliable performance characteristics .Jaw crusher can be widely used in mining, stone factory, building materials, metallurgy, ceramics and other industries.


     This machine has a frame, movable jaw , eccentric shaft, jaw plate, toggle plate and other component parts , The frame is  overall steel structure , racks forearm has jaw plate with wedge bolt fixed . At the sidewall of frame around the crushing cavity has guard plate, in order to prevent the wearing of machine frame.

     The movable jaw is wear-resisting cast steel, the frontage install sewing plate. The upper hanging by eccentric shaft and roller bearing on the rack, the lower support on the bracket, and rolling contact directly with the bracket, on both ends of eccentric shaft equipped with flywheel and pulley.

     Under the Supported by the adjustable seat, the other side of the bracket contact with the bearing rolling. In addition to support the moving jaw, the bracket plays the role of security which refers to break quickly to protect other components from damage when the feed materials cannot be broken into the crushing chamber and the machine loads suddenly increase.

     When adjust the discharging granularity, the adjustable seat installed in a frame on both sides of the sliding groove, and next to the wedge. When discharging to be adjusted, with a wrench nut right-handed ,the adjustable wedge immediately rise, adjustable seat and then move forward, so discharging is from big to small, otherwise changes from small to big.


Working Principle

     The motor drives the belt and belt pulley, and makes the movable jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw down,the angle between the fixed jaw and movable jaw gets smaller. The movable jaw plate leaves the fixed jaw plate by the function of drawbar and spring, and then the crushed materials are discharged from the lower outlet of the crushing cavity.
