The PF300 can be fully customised to meet the needs of a wide range of applications and materials, and can be fitted with a sizer, a double-roll crusher or Sandvik?s CR800 series hybrid crusher.
A large capacity hopper and apron feeder allows it to be directly loaded by rope shovels, hydraulic excavator/shovels, wheel loaders or surface miners. Sandvik?s unique stability (patent pending) system allows the unit to remain fully mobile at all times, without the need for any form of temporary support.
The PF300 can work in combination with belt wagons, mobile transfer conveyors or load bridges as the connecting downstream link to the face conveyor – all of which can be supplied by Sandvik.
The physical size of the PF300 in a given application is determined by throughput, which can range from 2000 tonnes per hour up to 14,000 tonnes per hour. Throughput depends on a customer?s production needs, as well as rock density, rock fragmentation and rock hardness.
The PF300 is designed for initial processing (primary crushing) and is capable of handling a wide range of materials, from overburden, through to various ore types, as well as coal, rock and aggregates.
The crusher type to be used with the PF300depends on rock hardness (UCS), with the Sandvik hybrid crusher option capable of handling up to an average UCS 150 MPa.
According to Sandvik, in an application where the PF300 is used to process overburden material, only the larger rocks would need crushing to fit onto a conveyor belt.
In an ore or aggregate application, the material can be crushed to a specific size range to meet the required size distribution.
The size of raw material able to be handled by the PF300 is determined by the crusher type and size, but maximum size versions with capacities of 14,000 tonnes per hour can handle rocks up to maximum of 1.5m by 1.2m by 2m.
The PF300 also has the ability to be reconfigured as a customer?s needs change, in terms of output, materials types and sizes, with settings and picks able to be adjusted to suit a new size range.
According to Sandvik, in any size/throughput combination, power requirements will be at least 10 per cent lower than a conventional crushing system due to its new design.
Compared with traditional truck and shovel materials haulage systems, power savings are set to be even higher, says the company.
Sandvik estimates the PF300 will typically be 10 per cent smaller than existing mobile crusher designs, primarily due to the compact design of its unique track system – with two track sets under each end – which also gives very low ground-bearing pressure.
Complementing the PF300, Sandvik offers a wide range of crushing, screening and conveying products in all relevant sizes, allowing it to provide a complete IPCC system.
