The crushing equipment is generally used for reducing the size and changing the shape of large rocks or gravel. The crushing equipment plays a vital role in the construction and industrial sector, but its most important role is in the mining industry. In the mining industry, the crushing equipment is used to crush raw materials and for creating underground tunnels for the workers. Many years ago, people used hand-made crushing equipment composed of wooden sticks and stones. Maybe it does not sound very genius, but it was very efficient in that time. Today, innovative crushing equipment is used, made from steel or iron for efficient and easy operation. Depending on the application, the operators can choose different crushing equipment. The most commonly used crushing equipment includes the following machines:
Cone Crusher – The cone crusher is crushing machine that uses compressive force to crush raw materials between convex and concave shaped surfaces. Used as a second crusher, the cone crusher is a very efficient piece of crushing equipment, because it is capable to crush a variety of mid-hard rocks and ores. The crushing process involves several steps, it starts when the material enters the machine from the top, getting compressed between the bowl-liner and the mantle, and being broken into small materials.
Jaw Crusher – The jaw crusher is most commonly used crushing equipment, and its working principle depends on the compressive force. It breaks raw materials by compressing them between a pair of jaw plates. One jaw plate is fixed and the other moves back and forth. The raw materials remain between the two jaw plates until they are crashed into smaller parts to pass freely through the small gap at the bottom. The jaw crusher is specially designed heavy-duty crushing equipment, most commonly made from steel and cast iron.
Gyratory Crusher – The third suggested type of crushing equipment is the gyratory crusher. By its design and concept, the gyratory crusher is identical to the jaw crusher, as it consists a concave surface and a conical head. The gyratory crusher is most commonly composed of a long spindle that carries a steel conical grinding element, known as head. Like the jaw and the cone crushers, the gyratory crusher places the raw materials between two blades and crushes them until their size is greatly reduced.
