Selected Aspects of Modelling and Design Calculations of Roller Mills
An analysis of construction was conducted in this study, and the guidelines for designing roller mills used commonly in the agri-food, chemical, power and construction industries were presented. Quick designing of the machines required existence of adequate mathematical models. Within the framework of the study’s realization, a mathematical VERTIMILL® is TON’s gravity-induced, vertical stirred mill. Its vertical configuration allows for large throughputs while maintaining a small footprint in your circuit. The VERTIMILL® can bring up to 40% savings in energy consumption in some cases, and helps in reaching excellent recovery rates by producing a sharper particle distribution.TON Vertimills
