Process technology – crucial for outstanding powders and bulk solids

Process plants

Every day, powders and bulk solids are used in countless products, such as construction materials, plastics, paints, fertilizers, and many others. Process-treated bulk solids are an essential component of numerous materials and are crucial for product quality. To ensure this quality, process technology processes must meet numerous parameters, such as exact particle sizes, particle densities, and residual moisture content (dry substance).

We contribute our expertise and our technologies to ensure that your powders and bulk solids are processed with the best possible quality and process efficiency. Grenzebach works with a holistic approach. We keep different bulk material properties and reaction behaviors in mind.

Our experts have in-depth knowledge of diverse powders and bulk solids used in industry. We support our customers from planning and design to commissioning and maintenance.

Whirlwind mill: Grinding soft to medium-hard bulk materials

Grenzebach’s whirlwind mill ensures excellent results in the field of fine and ultra-fine grinding of soft to medium-hard bulk materials (up to Mohs hardness 5). The whirlwind mill can produce very fine powder qualities with narrow particle size distribution and excellent upper particle size limitation.

Sample applications:

  • Limestone
  • Cellulose insulation
  • Gypsum
  • Pigments
  • Salts of various origins

Vibration tube mill: Grinding medium-hard and hard products

Grenzebach’s vibrating tube mills are the solution for grinding medium-hard to hard, abrasive products. For example, they can grind slags, ashes or fireclay and operate according to the vibromill principle. In this process, Grenzebach’s vibration tube mill achieves consistently high throughput rates with low energy consumption.

Sample applications:

  • Ashes
  • Slags
  • Quartz
  • Fireclay
