About Us

Bulk Solids Modelling was set up in 1997, in Perth, Western Australia.

Peter Donecker, Principal of Bulk Solids Modelling, has over 25 years experience in the Australian mining and minerals processing industries. Always an innovator, during this time he has chalked up a number of 'firsts', and offers consulting in a range of fields associated with these industries. Some of these are presented below.

Conveyor Transfer Modelling

The first conveyor loop dedicated to the physical scale modelling of conveyor transfers was installed by Peter at CRA-ATD in Bentley, Western Australia in 1992. Using this loop, the fundamental theoretical basis of the modelling was developed (Ang and Trewella, 1994) and design projects were conducted both commercially and in association with Curtin University (Tonkin, 1995). Test Loop

Verification of the real-world similarity between model results and full scale conveyor transfers was conducted through a detailed comparative examination of actual and model behaviour of 5-6E conveyor transfer at Hamersley Iron's Dampier Port Operations. Subsequent commercial projects spanned coal, iron ore and bauxite operations More recent student projects using this equipment, carried out by students from The University of Western Australia, have investigated advanced techniques such as video tracking of particle trajectories (Goodchild ,1998;: Bennett, 1999)

The Smart Conveyor Belt

After studying the problems associated with condition monitoring of conveyor belts in Western Australia's iron ore industry, Peter was the inventor a system incorporating radio frequency transponders for monitoring conveyor belt condition.

This invention (German Patent DE 44 44 264, 1994) was developed and commercialised by ContiTech of Germany as the first implementation of the ContiTronicĀ® Intelligent Belt.

Advice on new and novel applications of radio frequency transponders is offered as a service by BSM.

Smart Tags

Recognising the problems associated with tracking ore through complex material handling systems, Peter first conceived using radio frequency tags for ore tracking. These tags, individually identifiable, can be placed in the ore at the mine and tracked right through to the ship-loading process.

The first demonstration of this concept was conducted on the laboratory conveyor loop, and the concept progressed to field trials, with the first such trial taking place in 1993. BSM is available for consultation regarding applications of this technique within mineral processing operations.

Screen Wear

Worn Screen Panel

In one of the only studies ever reported on the topic, Peter's paper "Assessment of Screening Media Wear" details the findings of an extensive investigation into the performance of polymeric screening media in the mining industry. This study incorporated a range of advanced techniques such as image processing and high speed cinematography, as well as the more time consuming Vernier gauge measurement of screening surface thickness.

If you are experiencing problems associated with screen wear, BSM can provide advice and assistance.

Ball Milling

The disposal of toxic organo-chlorine wastes is a problem of widespread concern throughout the world. A similar problem is the safe disposal of chemical weapons such as Sarin and mustard. One of the recognized techniques for disposal of these materials is the use of high intensity ball milling with reagents such as calcium oxide. Peter was one of the inventors of the first process using this technique. (US 5,648,591).

He has also worked in the areas of wear in wet stirred ball mills, and dry grinding in stirred ball mills, including the development of the world's first pilot plant for the production of nano-powders using dry grinding.

BSM welcomes enquiries concerning fine grinding processes.
