Construction of two MMD Semi-Mobile Sizing Stations is underway in Northeast Inner Mongolia Autonomous Region. Xilinhe Coal Chemical Co Ltd, part of China Energy Group, also known as CHN Energy and the largest coal producer in the world, placed the order with MMD China through Ningxia Coal Construction Company in February 2021 to help meet the mine’s expansion goals. This will see annual production increase from 3 Mt/y to 15 Mt/y. The mine’s estimated 652.92 Mt coal reserve is forecast to serve for a minimum of 39.5 years.

Temperatures within the mine can drop as low as -42.1 °C during the coldest months of the year. MMD have machines operating in colder environments around the world, but this is one of the coldest within China. Fed by trucks each Semi-Mobile Sizer Station features a MMD 1150 Series Sizer and a D7 Feeder, capable of processing coal at a rate of 2,200 t/h. Manufacturing of the components has been a collaborative effort from several MMD facilities worldwide. For ease of installation, final assembly is being conducted on site with prefabricated sections. The sizer stations are due for completion later this year.
