In 1999 MMD delivered and installed a 625 Series Sizer to a lignite operation in the Czech Republic, now, more than 10 years later the same operation has increased their production targets and turned to MMD again to meet these new demands with a new 625 series sizer.

Original 1999 Installation

Both the old and new machine sit side by side (Picture above) and are fed by a single belt conveyor delivering lumps of up to 400mm into the sizer infeed chute which is simply partitioned in the middle to deliver approximately 50% of the material to each sizer. All the sized material is then collected onto a single takeaway conveyor via the outfeed chute and sent to the power plant. The machines are almost identical and produce an average throughput of 1800tonnes per hour each, thereby generating an overall increased production average of 3600tonnes per hour through the system.
