Vertimill models

The Vertimill design was based on modelling and simulation techniques. Laboratory tests data were used for the scale-up of Vertimill size reduction performance

    Jan 01, 2014 1. Introduction. An investigation program of Vertimill™ was conducted with the aim of development of models to scale up and simulate this type of mill.Pilot tests with Vertimill™ was carried out under controlled conditions to produce a mass balance and tests with small quantities of samples were carried out in lab to determine breakage parameters to simulate this type of mill

    The Vertimill screw is protected by cast liners in carefully selected wear-resistant alloys. There are two types of screw liners: end liners at the lower end of the screw and wear liners. The liners offer a long, aligned wear life. A few liner models are fitted with rubber pads to ensure a perfect fit

    Jul 01, 2014 The Vertimill™ is a vertical agitated media mill with a double-helical steel screw agitator located centrally in a vertical cylindrical shell.The screw agitator lifts the media and circulates it throughout the mill. The higher efficiency of the Vertimill™ is due to the higher frequency of lower energy impacts and, by the same token, smaller frequency of higher energy impacts when compared
