Economical Jaw Crusher/Compact Jaw Crusher/Jaw crusher

Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer frame is generally made of cast iron or steel. The jaws themselves are usually constructed from cast steel. They are fitted with replaceable liners which are made of manganese steel, or Ni-hard (a Ni-Cr alloyed cast iron). Jaw crushers machine are usually constructed in sections to ease the process transportation if they are to be taken underground for carrying out the operations.

In the Fote type jaw crushers, the jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening. The Fote jaw crusher has a variable feed area and a fixed discharge area which leads to choking of the crusher and hence is used only for laboratory purposes and not for heavy duty operations.

Jaw Crushers are used extensively throughout the world by the aggregate and mining industries. Their large physical size and rectangular feed opening enable them to receive a larger feed size than most other types of crushers. Rugged construction, simplicity of design and the ability to crush most types of material, including hard abrasive stone, make them ideally suited for use as the primary crusher within a crushing circuit.
