The Jaw Crusher As Vital Equipment For Rock Crushing

By Lila Barry


One of the most widely used and important rock crushing equipment is the jaw crusher. It is widely utilized in various industries such as mining, building material, highway and railway construction, together with the chemical industry. The machine is mainly applied in crushing medium and coarse rocks in some departments the likes of infrastructure construction.

There are several types of jaw crushers under numerous classifications. According to a machines feeding width, it can be divided into either a small, medium-sized and large crusher. In this category there are two major types, a fine jaw crusher and a coarse jaw crusher. The two types can be utilized either independently or when connected to various mine selecting and gravel processing equipment.

The two main types are further divided into numerous sub-types, including aggregate crusher, mobile jaw crusher, mini single toggle crusher and many more. Each feature of these machines is designed in a manner that it provides superior quality and performance. They have a wide variety of uses in crushing various materials such as granite, stone, trap rock, manganese ore, fused aluminum, lime stone and many others.

It is vital to have knowledge of how the jaw crusher works and operates. It has a motor that transmits power via a belt, a fixed jaw that surrounds and eccentric shaft, and a moving jaw. The belt drives the moving jaw to make an upward movement, reducing the angle between it and the toggle plate and closing the fixed jaw to it. In the process, the rocks fed to the machines inlet are crushed.

When the moving jaw makes a downward movement, the angle between it and the toggle plate reduces, enabling it to move away from the fixed jaw though the pulling of a spring and rod. The crushed materials will then be discharged from the machines outlet.

The jaw crusher has several significant performance characteristics, a notable one being the depth of its crushing chamber and absence of a dead zone. This not only improves the final output but also its ability to input materials. In addition, it has a high ratio for crushing together with even product granularity. The adjusting device for the gasket mouth reliable for discharging the crushed rocks is reliable and convenient. Also, its adjusting ranges have adequate width for increasing the flexibility of the machine.

The jaw crusher has a safe and reliable lubrication system, while its spare parts can be replaced conveniently, easing the process of maintenance. Additionally, the structure of this piece of equipment is simple, its working condition reliable and the costs incurred during its operation is low. Energy saving is facilitated by this machine, since power saving in the range of 15% to 30% is possible with a single machine. The materials discharging mouth can be adjusted to various ranges, easily satisfying different customer requirements.

An ideal jaw crusher comes with several major advantages such as solving the problems associated with high operation rate and little time for performing maintenance. Such problems are caused by the low output of limestone crushers. With it, electricity use is reduced and the granularity of waste is minimized. Additionally, the machine is capable of completing the work of rock crushing particles such as limestone with large sizes.
