Energy and Densification Systems (Pty) Ltd is based in Bryanston, Johannesburg, South Africa. EDS has strategically registered international patents in over 45 countries. These include South Africa, USA , China, Australia and Europe.
 
The company was formed in 2005, to develop, manufacture and market the EDS Multishaft Mill. EDS initially only had the rights to the patent and did not own the patent outright. During the period 2005 to 2009 the company carried out over 1000 successful batch tests for various clients from different industries. In 2011 the company acquired the patents from the original inventor. EDS was then restructured and recapitalised in order to carry out further research and development of the mill. This included further testing on various products. Towards the end of 2012 the EDS mill was introduced to the South African market as the Generation 2 Multishaft Mill.

The company has its own batch testing facility in Germiston, Johannesburg. This facility is used to test various products and to optimise the mill for each customer. This process involves adjusting numerous variables, including feed rate, shaft speeds, shaft orientation, and discharge rate in order to achieve the best recipe for the material concerned and to meet the customer output specification.
 
The mill can be combined as a unit with various other pieces of equipment to provide a complete processing and handling solution for the customer. These would include various types of feed and material handling systems, scalpers and pre-crushers, screening equipment as well as classifiers and filter systems.
 
EDS offers the customer a compact, efficient, power saving solution when compared to existing and obsolete technologies.

The EDS Multishaft Mill has applications in a wide variety of industry and product sectors. Industry sectors include mining, energy, steel manufacture, waste reprocessing, environmental rehabilitation, agriculture and general milling.
 
EDS’s target market is the milling and densification of various ores (gold, platinum, chrome, etc) coal, coal waste, silica fume, silica sand, talc, quartzite, clinker, graphite, biomass and various mineral and ore waste materials, to name but a selection.
 
The technology uses lower amounts of energy to produce the same outputs and therefore provides cost savings to the user. It also offers space saving due to its compact footprint and therefore provides the added benefits of remote operations and mobility. Owing to the fact that the mill consumes significantly lower amounts of power, it is possible to operate it off diesel driven generators.
 
The mill provides environmental benefits at multiple levels including reducing waste from coal fired power plants due to the finer milling and therefore reduced ash production. The mill is also able to extract value from mineral waste dumps through recovery of discarded mineral products – thereby contributing to environmental clean-up.
 
The EDS Multishaft Mill is designed and produced in South Africa.
