Mining, Machinery and Developments

From Sizers to the world’s most advanced Fully Mobile Sizer, MMD has been at the forefront of Mineral Sizing and In-Pit Sizing & Conveying (IPSC) technology for more than 30 years. MMD designs and manufactures material processing equipment for both surface and underground mining operations, handling over 75 different minerals in more than 60 countries.

In 1978 MMD created the original compact Twin Shaft MINERAL SIZER™, which has progressed from a 500 series machine to the 1500 series, with capacities of over 12,000 tonnes per hour. The Sizer has the ability to process wet sticky material or hard dry rock or a combination of both through the same machine.

To complement the robust Twin Shaft Mineral Sizer, MMD has designed and developed a range of Heavy Duty Apron Plate Feeders, which convey unbroken material to the Sizing plant.

MMD has also successfully designed and manufactured fully mobile, semi-mobile and static Sizer stations to provide complete mineral sizing solutions. IPSC systems are a more cost-effective and safer alternative to the discontinuous transport of material by dump trucks out of the mine. In fact, IPSC systems significantly reduce or even eliminate dependency on dump trucks, helping customers achieve environmental management goals, with a reduction in greenhouse emissions, dust and noise pollution.

MMD remains a group of committed and experienced individuals with the skills and knowledge to provide reliable solutions for customers, offering local after-sales and technical support via a global network of offices.
