| Résumé : |
Wet grinding as a process has been around for hundreds of years, with technology constantly refining what's opssible in terms of efficiency and quality. 2020 sees the introduction of a step-change in technology that arguably takes the industry to the limits of the physics of what's possible. But that's not the end of the story ; a new digital horizon could continue to drive progress for the next decade. |
| Note de contenu : |
- The 5 fundamentals of wet grinding
- 1. Uniform particle distribution is the ultimate goal
- 2. Different material types require different amounts of energy
- 3. Different forces are required to reduce sizes in different materials
- 4. Target properties require different approaches
- 5. The smaller the beads, the more efficient the process
- The history of wet milling
- A step change in technology for 2020
- 1. New technology enables even smaller beads
- 2. Introduction higher flow rates
- Entry-level dashboards to improve decision-making
- Next level statistics and insights
- The ultimate goal - Smart algorithms to minitor and optimise the process
