Jaw Crushers

First stage, primary rock crushing plants

Parker have been engineering rock crushers for over 100 years and today thousands of jaw crushing machines and units have been installed around the world.

Jaw crushers are used mainly in first stage, primary crushing applications and are ideal for use in quarries and recycling demolition operations. The two main types of jaw crusher produced by Parker are both single toggle designs with the up-thrust toggle RockSizer / StoneSizer model and down-thrust toggle RockSledger model.

Base Units


The RockSizer / StoneSizer up-thrust single toggle design has specific features that benefit the user with lower manganese wear rates and power consumption per tonne of material crushed with improved product shape whilst maintaining higher outputs than old double-toggle style designs. The ten standard models in the RockSizer / StoneSizer range cover output capacities from 5tph to over 200tph.

The RockSledger down-thrust single toggle design provides a more aggressive crushing motion and subsequently higher capacities are achieved. Six standard models in the RockSledger range provide outputs from 70tph to over 850tph and are at the core of the designs used by Parker in their ranges of static, transportable and mobile jaw crushing plants.

Features of both model ranges include:

  • All steel fabricated body with single steel plate walls and side stiffening webs
  • High quality nickel chrome, fully machined eccentric shaft
  • Self-aligning spherical roller bearings are grease lubricated with valves to prevent over greasing
  • Machined cast steel jaw stock with deep integral stiffening webs for lightness and high strength
  • High quality iron casting toggle plates radially machined to reduce rubbing and wear
  • Wedge locked, manganese steel corrugated tooth jaw plates are reversible to extend wear life
  • Wear resistant liner plates fitted to sides of crushing chamber for protection of inlet and outlet
  • Hydraulically assisted jaw adjustment and groove block shim placement
  • Balanced flywheels are designed to ensure kinetic inertia is maintained for higher throughputs
  • Options for mounting within static and mobile plant configurations

Rocksledger Jaw Crushers

Rocksizer

For primary stage medium to high capacity hard rock crushing or demolition applications

RockSledger jaw crushers feature massive, stress relieved, single plate walls with deep and substantial external side stiffeners and a high quality forged steel eccentric shaft.

The shaft is fully machined and has a ground finish on all bearing contact surfaces to increase resistance to shock loadings resulting in longer machine life.

Rocksizer Jaw Crushers

Rock Sledger

RockSizer primary stage jaw crushers feature the upthrust toggle action which is also common to the StoneSizer range. Developed by Parker, this gives a slight downward movement to the swing jaw that promotes a forced feed and therefore increased output while at the same time minimising any rubbing action resulting in a well shaped product and reduced and even wear on the crushing jaws.
