Roland martini, the pfeiffer area manager for the arab region, delivered a brilliant presentation on the topic “vertical roller mills – the energy efficient grinding technology”, in which he compared the common grinding technologies in terms of energy consumption and total investment cost.
advantages of roller mills. 1. produce more uniform, fewer fines, and oversized particles when it comes to product quality. 2. generates less heat (0 – 3 0 c) unlike hammer mill that generates up to 10 0 c. 3. less moisture loss. 4. better work environment due to low machine noises level.
The vertical roller pre-grinding mills developed by amcl machinery limited are based on technical knowhow from nihon cement co. ltd. japan. these machines are used for substantial power saving and capacity enhancement in the field of clinker and raw meal grinding.
It is characteristic of grinding in vertical roller mills that the energy input to the material per pass between roller and table is small, for which reason a large number of passes are required to obtain the necessary specific energy input to the material.
the vertical roller mill (vrm) from loesche is a solution for mines today which has a direct and positive effect on all spheres of the environmental pressures experienced. apart from water and chemical usage savings, the major saving is related to power and the effect on a mine’s financial bottom line.
When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. a dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.
