Double Toggle Jaw Crusher(Primary Jaw Machine)

Our Company has been the pioneer in the manufacture of stone crushing plants.

Working Principle
The pulping of fed material is achieved by a set of jaw plates made of MN steel. One of the jaw plates is fixed while the other is moving(swing jaw plates). The swing plate moves by the thrust of toggle plate which takes force by pitman, rotation of which is created through the eccentric shaft that rotates eccentrically by the flywheel which is driven by the V belt connected to electric motor or diesel engine , as prime force.

Feature Of Double Toggle Jaw Crusher

  • BODY is fabricated with tested quality M.S. plates which are reinforced by the M.S. Plates working as horizontal members and vertical members to the body .
  • Body of LEVER is fabricated with M.S. plates or is C.I. casted material. The lever consists M.S. pipe , M.S. pin, bushes etc.
  • PITMAN is the pitman assembly has the main body of mild steel and M.S pipe. The pipe holds one eccentric shaft, two bearings and toggle bearings are inserted at the bottom of the pitman body to house the toggle plates.
  • JAW PLATES are of MN steel containing 12 to 14 % MN. conforming to I.S.27B grade II.
  • TOGGLE BEARINGS are either of cast MN steel or fabricated of high quality steel.
  • FLYWHEEL are two in number where one flywheels is used for balancing while another is prime mover, which rotates by the eccentric shaft. The main power used for rotation is electric power of diesel engine.
  • TOGGLE BLOCK AND VIZ BLOCK both parts are of C.I. material , properly machined and provided in the rear portion of jaw body. The function of toggle block and viz block is to control thrust produced in the pitman and to adjust/set the stock of the swing jaw plate.
  • LUBRICATION the provision for greasing the bearings and pin etc. is provided, however ,self aligning double roller spherical bearings and cylindrical roller bearings are fitted providing grease holding space. The loss of grease should be compensated by the repeat greasing after every 10 days
