JAW CRUSHERS

jaw-crushers-2

Our Jaw Crushers are configured for Primary & Secondary crushing of even hardest rock at hardest speed with minimum power. The crusher is designed on principal of “Crushing without Rubbing” with high impact pressure. Our Jaw Crushers are considerably higher than that of conventional crushers, without rubbing & requires minimum dust oil lubrication.
The company crushers are designed for long life service with minimum maintenance with high quality promised for hard, tough, abrasive material and overload high capacity. The company all products are also well suited to high efficiency, large capacity size operation.

Mainly Jaw Crusher Are In The Two Lubrication System :

  • Oil lubrication
  • Grease lubrication

Main Parts Of Jaw Crusher :

  • Body
    • Manufactured from Fabricated with tested quality of M.S. Plates which consists of box beam design on outside of machine
    • Those body used after heat treatment process
    • Reinforced by the M.S Plates
    • Providing as horizontal members & vertical members to the body
  • Lever
    • Fabricated with M.S plates
    • Consists of M.S pipe, Forged M.S pin, bushes etc.
  • Pitman
    • Assembly has main body of mild steel
    • Pitman is always in compression condition
    • Pitman having unique design, one is always in contact with crank shaft and other is in contact with Pin
    • The bottom of the pitman body the toggle bearings are inserted to house the toggle plates
  • Jaw Plates
    • Jaw plates are made of High Manganese Steel & Suitable for easy setting & less rubbing
    • Containing 12 to 14% Manganese
    • Conforming to I.S.276
    • Different types of Jaw plates are available to suit particular crushing application
  • Toggle Bearings
    • Toggle bearings are either of cast MN steel or tempered steel
  • Toggle bearings are either of cast MN steel or tempered steel
    • Flywheels are two in numbers
    • One flywheel is used for balancing
    • Another is prime mover that rotates and hence rotates the Cranck Shaft also
    • Used for rotation on electric power or diesel engine
  • Toggle Block and Viz. Block
    • C.I materials
    • Properly machined
    • Provided in the rear portion of the jaw body
    • Toggle Block is to control thrust produced in the pitman
    • Used to Adjust/set the stroke of the swing jaw plate
  • Lubrication
    • Automatic continuous splash lubrication by gear pump to prevent bearing pitman, eccentric shaft and toggle mechanism, enables the crusher to run safely at relatively higher speed
    • Self-aligning double roller bearings
    • Cylindrical roller bearings are fitted providing grease holding space
    • Anti friction grease-3/equivalent should be used as lubricant grease
  • Crank Shaft (Eccentric shaft)
    • Eccentric shaft is made of special steel ( EN 8 / EN 24) and having high strength to resist load, which is mounted on the two roller bearings

Typical Applications :

In taking boulder & crushing it to smaller sizes stone of different sizes

  • Granite, River Gravel
  • Basalt, Bauxite
  • Coal
  • Lead & Zinc
  • Quartz & Quartzite
  • Iron ore, Manganese ore & Copper Ore
  • Dolomite, Limestone
  • Calcium carbide

Specifications :

  • Carborundam Capacity up to 450 mm
  • Feeding size up to 1260 mm aprox
  • Final grain size 20 mm depending on feed and material size
  • Reduction ratio 1:8
