Overview
Metso draws from more than 100 years of mill design and manufacturing expertise, and over three decades of successful Vertimill® applications.
Since its introduction in late 1979, over 440 Vertimills® have been sold worldwide.
The Vertimill® has proven to be a versatile tool that exhibits many advantages over traditional ball milling.
The Vertimill® is capable of handling feed sizes up to 6 mm and grinding to products less than 20 microns, and has standard mill sizes ranging from 15HP (11kW) to 4500HP (3352 kW).
Main features of the Vertimill® are:
- Orebed® Magnetic shell liners – The permanent solution
- Automatically greased bearings
- VFD compatible – Unparalleled process control
- Excellent turndown – Can run at a minimum of 20% power draw which makes it excellent for regrind applications and others with highly variable flows
- Efficient high torque motor
- Solid steel grinding screw with bolt on replaceable liners
- Modular mill body
Benefits
