Roxon Oy, a part of the Sandvik group, is a mechanical engineering company and it is specialized in supplying equipment and systems for crushing, screening, short-distance conveying, storing and homogenizing of bulk materials, as well as offering after sales services. Roxon Oy had no previous experience in electronics.

Objective of the experiment was to create an inexpensive, reliable and small DC - High Voltage Power Supply for ROXON CLEAR -Dust Collector for conveyors. The previous ROXON CLEAR -system is based on an old HV-transformer technology. Therefore the components are heavy and expensive. Restricted environmental regulations means that only rare new belt conveyors can be delivered without any dust control system. The company expect that with this new microprocessor- and PCB-based, light and inexpensive ROXON CLEAR -system they will be more competitive on the market.

The new product will improve the company's conveyor component/equipment range to a new area and will strengthen their market share. Also the production cost per unit will be reduced from 15 K¤ to 4 K¤ which directly results in lower sales prices and significantly expands sales potential.

The project was technically a success to the company. A new type of DC High Voltage Supply for dust control system was developed. Though the system is not a completed product yet, it is now quite easy to continue the development work to the end. It is planned that the production of the new product would start before the end of year 1999.

The company gained experience with high frequency technology, transformer technology and designing and building high voltage power supplies.

Costs of the project were about 39 K¤ and duration 17 months, from October 1997 to February 1999. The payback period is about 8 months. Return on Investment (ROI) is about 1638% over 4 years.
