Processing
The Long Rake Spar processing facilities combine engineering expertise with experience to provide a range of services to the industry:
Washing
High performance washing facilities ensure Long Rake Spar products are provided to the maximum degree of cleanliness.
These facilities are also available for contract processing of customer-supplied materials.
Blending
Accurate blending by either weight or density can be undertaken to meet exacting in-house or customer defined specifications.
Drying & Screening
Moisture content is reduced to a minimum by processing aggregates and minerals through two high capacity rotary driers.
Dry materials are then screened through a sealed system, triple decked locker screens with integral
hammer-mill enabling granules to be produced at 0.5mm size intervals up to 12.0mm.
Wet Screening
Screening of wet products is undertaken through either a washing trommel at 90, 40 & 20mm
intervals or over a triple deck screening plant at multiple size separations between 3 & 50mm
Tumbler
Tumbling of materials is undertaken in a 20 tonne capacity drum to produce rounded cobbles and paddlestones.
