Modular plant with capacity of a large crushing station

{{image2-A:R-w:300}}The module comprises a large truck dump hopper, a Terex Jaques ST47 jaw crusher, a Terex Simplicity vibrating grizzly feeder, plant chute work, discharge conveyor and a galvanised steel structure.

Terex has installed its first MJ47 module at the Hanson Flagstaff Gully Quarry in Lindisfarne, Tasmania. The module included hopper wings, extended hopper and discharge conveyor and a rock breaker structure with walkways. The entire module was easily transported in 40-foot shipping containers direct to site, and a three-man team from Terex Mineral Processing Systems assembled the modular station on-site over a three-week period.

The installation site was positioned about 200m above the processing plant at Lindisfarne, overlooking the gully below.

Access was via a 1.2km dirt road. Incomplete earthworks did not allow direct access to the construction pad with heavy haulage transport, or a suitable set-down area for heavy equipment and shipping containers. All components had to be hauled up the access road in stages during assembly. These constraints would have presented a significant challenge to building a typical fixed plant in this location.

The modular plant’s pre-assembled sections allowed the team to load individual sections onto a smaller truck for transport to the assembly area. A 16-tonne mobile crane was hired to simply lift components directly from the 40-foot shipping containers.

A testament to the MJ47 modular plant design is the minimal tooling required for assembly. The entire plant was assembled using standard tools provided from a single service vehicle on-site. A 40-tonne mobile crane was brought in to lift the various sections into place. In addition to limited space, no mains electricity was available during assembly. A portable 10kVA generator, running on less than 10 litres of fuel per day, was sufficient to run all the required tools and an air compressor for the duration of the project.
