Project duration: 1 April 2016 – 31 December 2018


The objective of the project is the creation of a pilot ultra-fine grinding mill by up-scaling and improvement of an existing demonstrator mill.

The solution (technology)

The mill will be a vertical fine grinding mill, where gravity forces enable a higher filling level than in horizontal mills and a hydraulic pressure on the grinding beads. Deliverables of the project will be a containerised pilot plant, a fine milling process with very low energy consumption.
