50-500t/h Aggregate crushing Stone Jaw Crusher

It is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, marble, etc. The pressure resistance strength is under 350Mpa, suitable for primary crush. It can be used in mining, metallurgical industry, construction, road and railway building, conservancy, chemistry, etc. Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer frame is generally made of cast iron or strong 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).
