Both a macroscopic and a microscopic analysis of the wear parts has been conducted. A laboratory scale vertical roller mill with a transparent roller/table has been developed to further understand the material movements during grinding. The development of a simple wear test apparatus has verified the type of wear mechanism dominating the process.

The fundamental difference between the ATLAS and other tableroller mills is the bearing arrangement for the grinding table which is incorporated into the base of the mill. This enables an operation with a standard design gearbox instead of the typical gearboxes with integrated bearing section with long delivery times.
