An assured future

ASILIKOS, AFESIKOS and ASILIT – customers worldwide rely on blasting abrasives made from slag tap granulate by STEAG Power Minerals. The fact that more and more coal fired power plants with slag tap furnaces are being shut down will however restrict the production opportunities in future. But STEAG’s blasting abrasives specialists have taken precautions.

As purely mineral products without free crystalline silica, the disposable abrasives from the STEAG Power Minerals abrasives plant are not only particularly environmentally friendly, but also ideal for use on various surfaces. Thanks to a large number of different grain sizes between 0.04 and 2.8 millimeters, the products can be supplied individually for every application – and are therefore in great demand. The STEAG Power Minerals abrasives plant in Lünen, one of the most modern of its kind, can produce around 145,000 metric tons annually.

"These actions mean that there are currently sufficient materials available on call for the production of blasting abrasives until at least the year 2023."

As purely mineral products without free crystalline silica, the disposable abrasives from the STEAG Power Minerals abrasives plant are not only particularly environmentally friendly, but also ideal for use on various surfaces.

The STEAG Power Minerals abrasives plant in Lünen, one of the most modern of its kind, can produce around 145,000 metric tons annually.

Products based on slag tap granulate from coal-fired power plants form the core of STEAG Power Minerals’ range of disposable abrasives. However, the availability of the abrasives produced in coal-fired power plants to date will decline, because according to the recommendations of the German Commission for Growth, Structural Change and Employment, all conventional power plant units are to be shut down by 2038.

Securing raw materials: in the medium and long term
“As a result, our customers are increasingly concerned that there will not be enough abrasives available for their applications in the future,” says Andreas Hugot, CEO of STEAG Power Minerals. The STEAG subsidiary has positioned itself strategically on two levels in order to be able to serve the market in the future as well: On the one hand, the abrasives specialists from Dinslaken have secured the availability of existing slag tap granulate sources nationwide. At present, the company, which is located near Duisburg, still has access to significant quantities of fresh granulate from two German coal-fired power plants, and STEAG Power Minerals has signed an exclusive contract for the majority of this. In addition, for years now, every tonne not required for production has been stored. “These actions mean that there are currently sufficient materials available on call for the production of blasting abrasives until at least the year 2023,” explains Marcus Klenke, Head of the Blasting Abrasives Division at STEAG Power Minerals.

On the second level, the company is working on alternatives to obtaining abrasives from slag tap granulate. Andreas Hugot and his team had been searching intensively for almost ten years – now they have found what they were looking for. “We have found a raw material that we regard as an adequate substitute for slag tap granulate,” explains Andreas Hugot. “It is environmentally friendly and, as our tests show, performs excellently in terms of handling and blasting pattern.”

The managing director does not yet want to reveal more – just so much: “We will continue to be able to serve our customers comprehensively and according to their individual requirements in the future.”
