• Strong trend towards finer products even into submicron range
• Dry processing of these fine powder down into the submicron rage
• Increase processing efficiency
• Reduce specific energy consumption
• “contamination free” processing for High End applications
• Apply wet processing for ultrafine products & products in submicron range
• Master tailored particle size distributions & “shaping” of particles
• Trend to much bigger sized production capacities
• Optimized investment and running cost

Industrial minerals are geological materialswhich are mined for their commercial value, which are not fuel, not sources of metals. They are used in their natural state or after benefication.
Industrial Mineral Fillers are a variety ofprocessed industrial minerals that may beirregular, fibrous or platy in shape and whichare typically used in large volume in paper, plastic, paint and rubber industries.

Quality and consistency:
- Are a must and driver of technological advancements and is a market desire
- Target quality of powders need top quality of processing equipment
- Highest availability of processing equipment is a must and a precondition of mineral producers from their market/customers
- Consistency includes quickest service, global service networkand easy maintenance

• Strong trend towards finer products even into submicron range
• Dry processing of these fine powder down into the submicron rage
• Increase processing efficiency
• Reduce specific energy consumption
• “contamination free” processing for High End applications
• Apply wet processing for ultrafine products & products in submicron range
• Master tailored particle size distributions & “shaping” of particles
• Trend to much bigger sized production capacities
• Optimized investment and running cost
