Jaw Crusher: What Is It & How Does It Work? Vykin Machinery

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces A stationary jaw plate and a movable jaw plate control the movement of these jaw platesThat is why it needs to be monitored throughout the crusher’s lifecycle As excessive wear can cause a 10–20% reduction in production, it is important to find the optimal time for the jaw turn or change in terms of cost and benefit Again, with the same scenario with C130, we would have approximately a 70 stph reduction in production, inHow to improve jaw crusher performance and productivity TON

Common Jaw Crusher Injuries, and How to Avoid Them Mellott

Bridged Rock Rocks frequently bridge the throat of the jaw crusher When this happens, many companies will have some sort of equipment like a rock breaker to break or reposition the rock The operations that do not, however, are not only risking a drop in production, but they’re also risking injury Jaw Crusher Safety featuresIt’s socalled because the opening starts off wide then tapers down to a V where the crushed materials go to The size of a jaw crusher is measured by the top opening of the crushing chamber For example, a 48” x 42” jaw crusher measures 48” from one crushing jaw to another and is 42” across the width of the two crushersWhat Are Jaw Crushers and How Do They Work?
