mining machinery Developments (MMD) designs and manufactures mineral sizing (crushing) equipment and services for the mining, metallurgical, industrial minerals, alumina and other industries.
The MMD group of firms was founded in 1978, to style and manufacture equipment for the UK underground coal mining market. Today, MMD sizes more than 60 various minerals globally, in numerous varied method industries.
Minerals processing technologies and equipment
MMD gives minerals processing designs and equipment, utilising state-of-the-art technology, resources and supplies, aimed in the optimisation of minerals processing systems.
The core products – mineral sizers ( crushers ) and feeders – give a solution to troubles including variable ore properties, item specifications, internet site conditions and environmental issues. MMD aligns these against power fees, maintenance charges, manpower price and wear costs, to engineer a system developed with operability and maintainability.
Mineral crushers, feeder -breakers and sizing equipment
MMD sizing equipment is obtainable for surface or underground installations, no matter whether stationary or mobile, and for climatic circumstances ranging from arctic to tropical. A lot more than two,000 installed sizers (crushers), feeder-breakers and feeders present evidence of our knowledge and expertise.
Primary, secondary and tertiary sizers
MMD twin-shaft sizers were originally created to meet the needs in the underground coal mining sector, where traditionally inline breakers had been used. The initial parameters were to design a machine to manage in excess of 1,500t/hr.
Within maximum dimensions of 1,200mm wide by 600mm high, it was essential to size material accurately, deposit material in the centre from the conveyor belt, and for the machine to become lightweight and totally mobile, with all of the breaking forces contained within the frame.
Another requirement was to pass conveyable material with out further degradation. Also, if the machine stalled complete of material, it should be capable of clearing the blockage speedily, to minimise downtime. Must uncrushable foreign material enter the sizer, it must be capable of withstanding the violent shock with no suffering severe damage.
Having successfully achieved this within the demanding underground atmosphere, it became evident that the sizer’s ability to procedure each difficult, dry material, and wet, sticky material, might be applied to other underground and surface applications.
Mineral sizing equipment for underground mine and surface applications
Since 1978, MMD has refined and enhanced the sizer design, progressing from a 500mm centres machine, through to a 1,500mm centres machine, capable of more than ten,000t/hr.
The MMD sizer range now consists of main, secondary and tertiary sizers for wet and dry processing of metallic and non-metallic minerals for mining, industrial minerals and quarrying industries.
