Yes. TH Group solutions can be integrated into both new industrial developments and existing plant operations requiring upgrades, optimisation, or expansion.

Yes, the target mineral affects filter press configuration. Higher-value concentrates such as copper and nickel generally need a drier cake for concentrate quality and dry-stacking, while coal and tailings applications tend to prioritise throughput. Transmin configures the plate pack and pressing method to match the mineral and site requirements.

Both recessed plate and membrane filter presses are fully automatic, with PLC-controlled cake discharge suited to continuous operation. Recessed plate presses typically run at 10–15 bar and suit tailings that dewater well under filtration pressure alone. Membrane presses add a diaphragm squeeze in each chamber after filtration, achieving 3–8% additional moisture reduction, which suits fine, slow-draining tailings. The right choice depends on the tailings characteristics and moisture target needed for stable stacking, balanced against capital cost.

Membrane filter presses speed up dewatering by adding a mechanical pressing step after filtration. Once each chamber is filled, a diaphragm inside the chamber inflates and squeezes extra moisture from the cake beyond what filtration pressure alone achieves. This is most effective on fine, slow-draining tailings, cutting cycle time and increasing throughput per shift.

A filter press pays back beyond dewatering through water recovery and reduced haulage cost. Recovering water reduces reliance on raw water on site, and a drier cake weighs less to truck or convey to the tailings stack. For many operations, these savings are as significant to the business case as the filtration performance itself.
