Our History

1978

MMD Founded.

Founded by Alan Potts, Mining Machinery Developments (MMD) was setup to design and produce mining solutions for the underground UK coal industry, initially designing and manufacturing inline breakers.
1980

Sizer™ Patented

Although inline breakers for the coal industry were a great success, MMD did not stand still with this technology and went on to invent and patent the twin shaft MINERAL SIZER™, producing the first ever 500 series Sizer in 1980. Sizers were quickly adopted throughout the underground UK coal network.
1981

Specialised Sizer Gearboxes

To harness the Sizer’s unique capabilities and cope with the demanding underground environment, MMD designed a specialised gearbox to deliver the outstanding reliability and performance Sizers are known for.
1982

Sizers for Cement

Up to this point, coal had been the main outlet for Sizers, however, the Sizer's unique abilities started to be recognized and implemented in many other industries such as cement, metals, energy, precious stone, waste etc.
1985

First Track Mounted Mobile Sizer (Underground Unit)

With the Sizer tried and tested in many applications, MMD developed track mounted stage loaders and feeder breakers for underground coal applications, providing a reliable mobile alternative to the original inline breaker.
1987

First Track Mounted Mobile Sizer (Open Pit)

First seen and tested at UK based Hope quarry, this open pit mobile Sizer was dump fed by excavators and could process over 1,000TPH of limestone.
1989

First MMD Apron Plate Feeder

As the Sizer range grew and capacities increased MMD developed the apron plate feeder to provide a reliable high capacity feeding method. The first feeder installed was on a semi mobile Sizer unit installed in Spain in 1989 producing 3,000TPH; the highest capacity to date.
1991

Track Mounted Mobile Sizer Incorporating Apron Feeder

The first track mounted mobile feeder-Sizer unit on a single chassis incorporating an Apron Feeder was built in 1991 sizing coal in Venezuela. Processing up to 3,000TPH the unit consisted of a D7 apron feeder, 1150 series Sizer and discharge conveyor which fed to two secondary Sizers also mounted on tracks.
1993

First Large Semi Mobile with Dual Truck Bridges

The first of 3 large modular semi mobile units were delivered to a coal mine in Thailand. Trucks delivered up to 4,500TPH of overburden to each unit.
1994

10,000TPH Reached

The first Sizer to achieve 10,000TPH were static units in Canada processing oil sands. Each unit incorporated a 1500 series Sizer, the largest Sizer we currently manufacture.
1997

Semi-Mobile Unit Reaches 10,000TPH

Two semi mobile Sizer units each fitted with a 1500 series Sizer processed up to 10,000TPH of overburden from a copper mine in the US. This unit was re-located in 2 modules by a transporter.
2002

First 10,000TPH Capacity Fully Mobile Sizer Unit

Having proved the MMD Sizer and feeder was capable of producing 10,000TPH, and could be mounted on a relocatable semi mobile unit, the next innovation was to design a high capacity unit and mount it all on tracks. Installed in Australia this unit set the benchmark for large scale fully mobile sizing. Relocated regularly the unit worked in unison with the excavator along the mine face processing overburden.
2004

MMD Manufacturing Facilities Go Global

MMD had worldwide provision for sales, servicing and repair facilities, however manufacturing up to this point had been only in the UK. Due to demand another manufacturing plant was setup in Africa, and this was shortly followed by a manufacturing plant in China.
2013

MMD Transporter Developed

The first MMD Atlas 500T Transporter was installed in Africa to relocate semi mobile heavy structures around the mine with unmatched safety and control.
2013

First ‘FMS 1500T’ Installed in China

After years of research and development, the most compact and high capacity mobile Sizer in the world is installed in China processing overburden. At almost half the size of the first high capacity mobile unit in 2002 this unit takes high capacity mobile sizing and IPSC to the next level.
2018

First Fully Mobile SurgeLoader Developed

MMD's latest technology is bringing a new era for truck and shovel operations, by decoupling the traditional truck and shovel relationship. This scalable solution is capable of processing more than 15,000TPH and loads 330T trucks in less than 60 seconds - representing a potential 40% increase in production.
2020

Bulk Sorting Systems Launched

MMD's Bulk Sorting System uses an ore analyser to separate ore from waste within the pit, preventing unnecessary haulage of waste material. This offers massive energy and water savings as well as SAG benefits, whilst also providing up to a 20% uplift in ore grade.
2023

Purchasing of MMD Summerfield Ltd

MMD Group announced its acquisition of MMD Summerfield Ltd, a strategic move aimed at enhancing its capabilities.
