Mineral Technologies designs, manufactures and supplies the patented KAD Mill, specifically developed to meet the ever increasing demand for efficient and economical production of fine and ultrafine products.
The KAD Mill addresses issues that have become increasingly important to the comminution process, such as specific energy consumption, carbon tax, ultrafine particle production and mechanochemical material properties.
The KAD Mill works by delivering feed material through a shaft to a spherical grinding chamber where it is dispersed between an external rotating shell, and an internal counter-rotating sphere (or disc/pin assembly). Rotational speeds are adjusted to suit individual applications. As the surface of the shell and sphere accelerate, particle size reduction occurs autogenously (no grinding media). Grinding takes place predominantly via particle to particle shear and abrasion, as the particles transfer energy to communication.
Features
- Mechanically robust, the KAD Mill is designed with conventional mechanical components that have been over-engineered to ensure reliability
- Customised internal grinding elements (discs and spheres) achieve optimum performance
- The KAD Mill features self lining. Feed and product materials build up on the inside of the shell as a protective lining. There are no mill liners
- PLC controlled, providing history trends of key data plus the ability to integrate into a plant control system using conventional communication protocols (which can also be used for maintenance planning)
- Low noise, the KAD Mill operates without noise attenuation
Benefits
- The KAD Mill produces Fine and Ultrafine products under very economical conditions
- No grinding media requirements nor consequent contamination to product
- Efficient centrifugal milling at up to 1200G, providing power intensities of up to 5000 kW/m3
- Ability to accept large particle size feeds in the production of fine products
- The KAD Mill is versatile with the capability to quickly change to process alternative materials or produce different product sizes
- Safe and simple maintenance
Applications
- Iron ores, gold ores, calcium carbonate, zircon, baryte, etc, down to single digit microns, and especially materials with ‘platey’ or acicular properties such as talc, mica and wollastonite.
