Stone Crusher, Working Principle, Types And Its Role Played In The Industrial Sector?
The function of a stone crusher is to reduce particle size of stone, so that it could be ready for further processing. Raw material is fed to the crusher with the help of excavators or loaders. An apron feeder or conveyor is used to monitor the rate of raw material entry. Stone crushing finds immense applications in mines, buildings materials, infrastructure, construction sites. Raw material is fed to the crusher with the help of excavators or loaders. An apron feeder or conveyor is used to monitor the rate of raw material entry. Every crusher is designed so as to work on a specific material size. Primary or secondary crushing units are used for working on coarse materials. Fine ingredients are achieved by employing tertiary or quaternary stone crushers.
Crushing is basically the process of transferring a force using the mechanical advanced of materials. The force applied depends on the compressive strength of material. In a typical crusher machine, the raw material is held between 2 surfaces held tangentially or parallel to each other. Upon application of sufficient force, the molecules separate by fracturing or deformation.
Before selecting a stone crusher, the client must look for features like feed material and crushing work ratio. It must have a heavy eccentric shaft with a high bearing capacity.
A crusher machine reduces or changes stone form in such a way that the wastes can be disposed off with ease or recycled suitably. Crushing is used for preprocessing of materials to segregate materials with differing compositions.
Stone crushers are of the following types with specific roles in industrial sector. 1. Jaw crusher: It is used for crushing soft to hard materials, with medium compressive strength. It finds industrial applications in the case of heavy mining, cement industry, refractories and sand recycling.
2. Gyratory crushers: It is used for crushing stones which lie in soft to very hard range. It is used in heavy mining and quarrying. 3. Cone crushers: It is used for crushing stones of medium to extreme hardness.
4. Compound crushers: It is significantly used at building sites for crushing materials which are medium to very hard types. 5. Shaft impactors: These can either be vertical or horizontal. These are used for quarrying and gravel recycling. 6. Mineral sizers: These are used for materials with a varying range of hardness. These find application in heavy mining operations.
