Crushers are heavy duty machines that are designed to reduce the size of large materials. They are mainly used to change the form of waste materials so that they can easily be recycled or disposed of. Generally, crushers are low-speed machines that break large lumps of stones and ores. The main use of crushers is to decrease the size of materials so that they can be used in industrial and construction sites. There are different types of crushers. They are:
Jaw crushers reduce the size of materials by compression force. In this, the rocks are pressed against two blades. Jaw crushers consist of a set of vertical jaws. The rocks remain in the jaws until they become small enough to pass through the gap between the jaws. The speed of jaw crushers varies inversely with the size. The jaws of a jaw crusher are made from steel and fitted with replaceable liners.
Gyratory crushers consist of a long spindle, a conical grinding element, the head, and an eccentric sleeve. The spindle rotates and sweeps out a conical path between the fixed crushing shell or chamber because of the gyratory action of the eccentric sleeve.
Cone crushers operate similarly like the gyratory crushers. It has less steepness in the crushing chamber. When a rock enters cone crushers, it is squeezed between the bowl liner and the mantle. When the larger pieces are broken down, they fall into a lower position and are broken down further. This process continues till the pieces become as tiny as possible.
Roll crushers crush using compression with two rolls rotating about a shaft, towards a gap between the rolls. Roll crushers decrease the size of the materials and they produce very little dust. Generally, these crushers have raised forms or teeth on the surface of the rolls.
The impact crushers make use of impact rather than using pressure to crush the material. The material is placed within a cage that has openings of a desired size on the side or at the bottom end to allow the crushed material to fall out. The impact crushers are commonly used to crush soft materials like seeds, coal, or soft metallic ores.
These are the different types of crushers that are commonly used to reduce the size of large materials. If your job requires breaking down things, these heavy duty machines are all you need. If you want to own one, you should contact the heavy duty dealers soon.
