Construction of two semi-mobile MMD sizing stations is underway in the Northeast Autonomous Region of Inner Mongolia. Xilinhe Coal Chemical Co Ltd, part of China Energy Group, also known as CHN Energy and the world’s largest coal producer, placed an order with MMD China through Ningxia Coal Construction Company in February 2021 to help achieve mine expansion objectives. This will result in an increase in annual production from 3 Mt / a to 15 Mt / a. The mine’s estimated 652.92 Mt of coal reserves are expected to serve for at least 39.5 years.

Temperatures inside the mine can drop to -42.1 ° C during the colder months of the year. MMD has machines operating in colder environments around the world, but it is one of the coldest in China. Powered by trucks, each semi-mobile grader station is equipped with an MMD 1150 series grader and D7 feeder, capable of processing coal at a rate of 2,200 t / h. The manufacture of the components was a collaborative effort of several MMD facilities around the world. To facilitate installation, final assembly is carried out on site with prefabricated sections. The calibration stations are expected to be completed later this year.
