Reduce costs and emissions with FLS primary crushing stations

Crushing stations can be provided either partly or fully enclosed.

A personnel elevator can be provided to aid access on stations with high elevations.

Electromagnets/metal detectors can be supplied for the removal/detection of tramp metal.

Onboard electro-hydraulic jib or bridge crane up to 150t lifting capacity.

A primary crushing station is the first stage in mineral processing operations. It prepares ROM material for conveying and further processing, usually via secondary crushing and screening, where material is readied for subsequent grinding and flotation. 

A semi-mobile crushing plant is one that can be periodically relocated closer to the mining operations. This compares with stationary crushing stations and fully mobile systems, which are track-mounted to allow them to continuously follow excavation equipment.

Semi-mobile crushing plants comprise a truck ramp and tipping point, which feeds into the main crusher (if direct fed) or a feed bin (if indirect fed). Material moves through the crusher and drops onto a discharge conveyor. Additional components may include a rock breaker, jib or alternative crane, elevator, and tramp metal detector or electromagnet. Our crushing stations rest on large pontoons on a compacted gravel bed, without anchoring, to allow easy relocation using transport crawlers or self-propelled modular transporters.

The best crusher for primary crusher will depend on the material being processed and the requirements of the operation. In our experience, direct-fed gyratory crushers offer the optimum solution for most mining applications; however, alternative indirect-fed crushing options are available, including jaw crushers, double roll crushers, ABON® sizers, and the Eccentric Roll Crusher.

FLS primary crushing stations can handle capacities up to 14,000 tpd.

It takes six to eight months to erect an FLS primary crushing station onsite, depending on site conditions and the level of pre-erection and modularisation.

The size of our primary crushing station modules depends on several detailed design criteria, including the size of the plant, the level of modularisation, and transport limitations.

Delivery time for a primary crushing station is about 12-14 months from contract acceptance.

Relocation time for a FLS semi-mobile crushing plant depends on a broad range of factors, including the level of modularisation, distance between locations, working time, and method to transportation.

Screens are only required for indirect-fed primary crushing stations. Here, heavy-duty grizzly screens are used.
