The 350tonnes/hour MJ47 Modular Plant has been designed to meet the needs of a large capacity primary crushing station with minimal civil works, assembly time and cost. The Module comprises a large truck dump hopper, Terex Jaques ST47 Jaw Crusher, Terex Simplicity Vibrating Grizzly Feeder, Plant Chute-Work, Discharge Conveyor and a Galvanized Steel Structure.
The installation site at Hanson Flagstaff Gully Quarry was positioned approximately 200m above the existing processing plant at Lindisfarne, overlooking the gully below. Access was via a 1.2km dirt road. Incomplete earth works did not allow direct access to the construction pad with heavy haulage transport or for a suitable set-down area for heavy equipment and shipping containers. All components would need 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 16tonne mobile crane was hired to lift components directly from the 40 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 40tonne mobile crane was brought in to lift the various sections into place. In addition to limited space no mains electricity was available at the time of assembly. A portable 10kVA generator running on less than 10litres of fuel per day, was sufficient to run all required tools and an air compressor for the duration of the project.
