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 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.
