MMD says it recently completed a trial assembly at its home UK operation for a fixed Sizer station, due to be installed in Liberia. The MMD designed Sizer station, which will process iron ore, will include a D10 Feeder and a 625 Series Sizer. With almost all of the design, fabrication and trial assembly complete, the company says it is looking forward to seeing this installation commence onsite in 2024.

The 625 Series Sizer is one of MMD’s most popular machines as it can be configured for primary or secondary use in the same system on medium tonnages, allowing common drives for both primary and secondary units. The length of the inlet can be adjusted at the design stage to suit the tonnage required and can be constructed as a fixed or adjustable centres unit. A wide range of existing tooth configurations are available for this machine to cover most applications.

MMD says fixed Sizer stations combine conveyor haulage efficiency with truck and shovel flexibility to improve productivity and help users reach ESG commitments. “Fixed Sizer Stations are commonly fixed in position for the life of the mine and process ore or waste delivered by truck. Material is Sized ready for an efficiency haul by conveyor to the process plant. Using trucks within the mine delivers the versatility you require in the pit while sizing and conveying delivers high-efficiency.”
