6 Technical / Environmental Analysis

7 Powerscreen Training Academy Mobile & Static Plant

8 Stationary Plant Extensive civil work Untested and often complicated design Long commissioning / safety issue Material has to be moved to the plant Inflexible design Expensive to relocate Dead costs High depreciation

9 Powerscreen Training Academy Mobile Plant

10 Mobile Plant Simple to visualize and adapt Proven design Crushing can begin within 1 hour of arrival upon site Move crusher to material Flexible Easy to relocate Higher residual value No dead costs Feed and operate with minimal operators Easily transportable

11 Factors for Mobile Plant Urban Spread and the need for expansion or green field permits Life Span of a raw feed Environmental, for example exhaust emissions, noise and dust levels that may dictate working hours Country Stability (when moving into new areas) End user Aggregate pricing Aggregate specifications Recycling legislations Operator capabilities

12 Mobile Concepts The Benefits Flexibility Transportability Rental Leasing Low Maintenance Fixed Volume processing (Contractors) Residual Value It is much more cost effective & a time saver, to move the mobile crushers to the rock face than haul the material to the crushing plant

13 Mobile Plant Applications

14 Coals, Ores, Slag Industry

15 Recycling, Urbanisation

16 Powerscreen Training Academy Crusher Plant Technology

17 Hopper Locking Interface Fully hydraulic hopper Hydraulic ram interlocking operated from ground level Additional manual wedges not required

18 Feeder Options Pan Feeder Pre Screen Grizzly Feeder Belt Feeder

19 Feeder Options Effective removal of fines High efficiency Pan Feeder Pre Screen Grizzly Feeder Higher production Less wear Cleaner product

20 Pre Screen Options

21 Dirt Conveyor Hydraulic folding Universal mounting Machine mountable no need to dismount for transport Extended versions Telescopic head section

22 Product Conveyor Hydraulic raise & lower whilst crushing Modular units Excellent clearance

23 Product Conveyor Vibrating pan feeder and product conveyor Full length product conveyor Extended full length conveyors Folding head drum section

24 Jaw Chamber

25 CSS Adjustment / Overload

26 Impact Chambers Primary Primary / Secondary Secondary Rotor position in chamber Swirl angle is less on Primary Increased range in tip speed to utilise machines in secondary applications Larger unrestricted feed entry to Primary

27 Optional Grinding Path Control oversize Improve shape More fines created

28 Overload Protection Tramp metal in feed Aprons return to preset Direct crushing force Impact of the material

29 Adjustments Material Trajectory Hydraulic / Screw Thread /Shim Penetration is influenced by: Tilt angle and length of chute Size/shape feed Number hammers Tip speed Rotor diameter (larger the rotor diameter the greater the penetration for a given tip speed)

39 Liner Profiles Quarry Tooth Jaw Liner Super Tooth Jaw Liner Recycle Jaw Liner Suitable for both rock and gravel crushing. Very good wear life, power requirements and crushing stresses are in good balance. Most well suited for very abrasive and/or hard rock applications, good wear life. Moderate throughput capacity. Best all-round liner for both rock and gravel crushing and also for some recycling applications. Extra contact face affords better grip of material thereby increasing throughput. Not suited for very abrasive materials. Best suited demolition and recycling applications with small CSS requirements. Very good grip on smooth flat concrete faces. Not suited for abrasive or hard materials.
