Stone crushers are machines designed to reduce large rocks into smaller rocks, gravel, or rock dust. The materials used in the construction of stone crushers vary based on the type of crusher, its purpose, and the specific requirements of the application. Here are some common materials used in the construction of stone crushers:
Construction of stone crusher
Frame: The frame of the stone crusher provides structural support and houses the components of the crusher. It is typically made of welded steel or cast iron.
Jaws or Plates: Crushers that break down large rocks into smaller pieces, like jaw crushers or cone crushers, have jaws or plates made of hardened steel or alloy.
Rotor: In impact crushers, the rotor plays a crucial role in the crushing process. It is often made of high-strength steel and may have wear-resistant liners.
Blow Bars or Hammers: These components are found in impact crushers and are responsible for the actual crushing process. They are often made of high-chrome steel or alloy.
Bearings: Crushers have various bearings to handle the rotational movement of the shafts. Commonly used materials for bearings include high-carbon steel, stainless steel, or bronze.
Cone Liners: In cone crushers, the crushing action occurs within the chamber, and liners made of wear-resistant materials, such as manganese steel, protect the cone from wear.
Conveyor Belts: For conveying crushed materials, conveyor belts are commonly made of rubber or fabric-reinforced rubber.
Electric Motors: The motors used to power stone crushers are typically made of high-quality metals and alloys to ensure durability and efficient operation.
Screens: Crushers often have screens to separate different sizes of crushed materials. These screens may be made of steel, rubber, or polyurethane.
Hopper: The hopper is the receptacle for the materials to be crushed. It is usually made of steel or reinforced concrete.
The specific materials and their composition can vary between different manufacturers and models of stone crushers. The choice of materials depends on factors such as the type of crusher, the expected workload, the abrasiveness of the processed materials, and other operational considerations.
