Working Principles of Performance of Jaw Crusher

The jaw crusher is very widely used in the mining industry. This article will explore the working principles of the jaw breaker. One roller is supported on the fixing bearing, while the other roller is supported on the movable bearing. The movable bearing is pushed to the position of the stopper by the spring force. The motor drives the relative rotation of the two rollers. The materials are fed between the two rollers through the feed box. Since the materials suffer from the frictional force between the rollers and the materials, the materials are sent to the crushing cavity between the two rollers. After the materials are crushed and extruded, they are discharged from the bottom.
The minimum gap between the two rollers is referred to as the width of the discharge port. The granularity of the crushed products is determined by the size of the discharge port. The movable bearing can move along the horizontal direction. When the non-broken materials enter the crushing chamber, the stress of the rollers will suddenly increase. The roller and the movable bearing force the spring to move right so that the gap between the materials increases to discharge the non-broken materials. In this way, the bearing and other parts of the crusher will not be damaged. Therefore, it is the safety device of the crusher. Under the spring force, the movable bearing pushes the position of the stopper to the left. When the width of the discharge opening needs to be adjusted, you can change the position of the stopper. Therefore, it is also the adjusting device of the machine. The single-roll crusher completes the crushing work between the roller and the splicing lining plate which is installed opposite the roller. The liner may be smooth, grooved or toothed, but the roller surface must be toothed. Since the liner is hinged, its angle position can be adjusted so that it can change the distance between the liner and the roller. The liner is supported by a spring. When the non-broken materials enter the crushing chamber, the liner will move back for concession to discharge the non-broken materials.
The single roll crusher is also known as jaw roll crusher. The single roll crusher is composed of a rotating roller and a tooth plate. It has a lot of advantages. It has more compact structure and more excellent performance compared with the other crushers.
