The power signals are converted by signal processing equipment for presentation as pictorial display representations of mill operating conditions at a variety of motor current levels to permit unskilled operators to understand the current operating conditions.In fact, in the same application a Vertimill has 50 less footprint than a ball mill. Lower operating cost. Vertimill is an energy efficient grinding machine. They tend to grind efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40 higher energy efficiency.
The factors which have an impact on milling efficiency include mill internals (profile, length, filling degree, etcetera), grinding circuit parameters, ball type, size and density, mill operating parameters such as velocity, pulp density, percentage of circulating load. The filling degree and pulp density need to be monitored in real time.Cementos Artigas to shift grinding to Minas plant. The project will integrate the company’s grinding plant, currently located in Montevideo, with its clinker plant at Minas, 100km from the capital to achieve “a efficient and sustainable” unified production line, according to the company A new stateoftheart vertical cement mill and new cement silos will be installed at the Minas.
