Primary Jaw Crusher

RD Primary Jaw Crushers are designed to crush very hard rock like Granite, Black Basalt, River Gravel, Black trap rock, Iron Ore, Coal. Dolomite. Limestone. Etc. Whatever your crushing needs- from hard and abrasive rock to various recycling materials- you’ll find the optimum solution with the “RD” Primary Jaw Crushers. There are now two ranges of models in the ‘RD” brand Primary Jaw Crusher. The first is the known traditional Jaw crusher range that is designed for stationary as well as mobile applications (PJC 42″x36″, 44″x32″, 42″x32″, 36″x28″, 36″x24″, 30″x20″). The second range that is designed specially to meet the needs of small to medium size Stationary and mobile crushing (PJC 30″x15″,24″x15″, 24″x12″)


  • Heat treated shafts forged of special alloy to handle overloads and hard materials.
  • Heavy duty self-aligned spherical roller bearings absorbs and withstand extreme shock, radial and thrust load and offer substantially more bearing life.
  • Much heavier, stronger, massive one piece frame, stress- relived for optimum reliability.
  • Toggle bearing wedges for easy in, easy out bearing replacement.
  • Hardened barrel wear lines (Side plate) protect the pitman (Lever).
  • Replaceable Fix & swing jaw plate made out high chrome& manganese percentage.
  • One piece cast pitman (Lever) stands up to the most demanding crushing applications.
  • Larger stroke, deeper crushing motion, steeper nip angle means higher capacity and greater throughput.


  • Innovative Crusher Design Produces Unmatched Production Capacity.
  • Fly Wheel Design Reduce Horsepower Requirements.
  • Hydraulic Dual Wedge System Delivers Quick Closed Side Setting Adjustments.
  • Large Feed Opening and Force Feed Action from Eccentric Movement of Swing Jaw Increases Production Capacity


  • The output in TPH indicated above is based on average hard dry quartz weighing. At least 1.6 ton/m3 when crushed and on continuous feed of graded sizeswith lines removed.
  • Capacities may vary by 25 % dependingon type of rock. Gradation and method of feeding.
  • Where no capacity rating is given in the table, it is generally not economical to operate at such a setting.
