Jaw crushers have a jaw-like configuration and are mainly used to crush rocks and all kinds of stones, ranging in hardness from quartz, from 50 inches down to one-inch sizes. The size of a jaw crusher is determined by the square or rectangular feed opening at the top of the jaws. and are one of the main types of primary crushers used in the mining and ore processing industry.
Applications for Jaw Crushers
Jaw crushers philippines form an important part in a wide variety of industrial processes such as rock crushing in mining operations, production of building aggregates, trash compacting in recycling and waste management facilities, disposal of materials during demolition or construction projects, and materials management.
How Does a Jaw Crusher Work?
A jaw crusher is designed to exert impact on solid particles that are placed between the fixed and moving plates of its jaws. The plates are made of hardened steel and can be flat or convex. A fixed “jaw” in a ‘V’ alignment forms the stationary breaking surface while force is exerted by the movable part of the jaw on the rock materials to be crushed. The size of the crushed product is determined by the V-aligned jaw plates at the bottom of the jaw crusher.
Different Types of Crushers
There are three basic types of crusher:
- Primary crusher
- Secondary crusher
- Tertiary crusher
A primary crusher is capable of processing materials derived directly from a source like a quarry. In these instances, the crusher is fixed at the site where the materials to be crushed are taken from. It is primarily used to crush large stones to produce a reduced size for further processing. Its function is limited up to this point and is not meant for the production of aggregate size materials.
A secondary crusher is used to further reduce the size of primary crushed materials. Examples of secondary crushers include cone crushers, hammer mill crushers, and roll crushers.
A tertiary crusher is generally used to render the previously crushed stones into pieces that are very much according to the required size and also to refine the crushed materials. These crushers are generally used at the building site and are smaller in size than primary and secondary crushers. Materials to be crushed are normally transported by dump truck to the tertiary crusher at the working site. Examples of tertiary crushers include roll crushers, ball mill crushers, and rod mill crushers.
How to Select a Jaw Crusher
Selecting a crusher can be a complicated process because there are so many available on the market. In order to select the right crusher to perform the particular functions for your requirements it is important to take the following points into consideration:
- The size of the material to be crushed
- The maximum size of materials that the crusher can handle
- The type of feeding method
- The production capacity of the crusher per hour/day.
- The efficiency of the crusher
It is important to select the right crusher for your requirements. if a crusher has more capacity than required it will be uneconomical. As the size of a crusher increases the fuel burning rate and maintenance costs will increase. You can continue to browse here, https://www.linkedin.com/showcase/jaw-crusher-philippines.
