cement grinding vertical roller mill versus ball m

Feb 10, 2016· VRM has less flexibility in controlling particle size distribution.Overall ball miilis good option forCement millbut only has limitations for higher capacity, astwo ball millto be installed for One VRM, but in case ofbreakdown one ball millcan be in operation.

Thegrinding efficiencyof thevertical roller millcombined with an ability to dry,grindand classify within a single unit gives thevertical roller milla decided advantage over aball millsystem. However, despite these benefits, applications of thevertical roller mill for cement grindingare less prevalent.

Vertical roller mills offer supreme grinding with high energy-efficiency. Years of experience helping the cement and power plant industries achieve easy operation and maintenance, energy efficiency and cost savings underpin our expertly-designed vertical roller mill (VRM) product range.

Vertical roller millare suitable for huge capacity producing, widely used ingrindingnon-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag,cementclinker, zircon sand, fly ash and carborundum, coal, etc.

Asvertical roller millsare 30 to 50 percent more efficient than othergrindingsolutions, they givecementplant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.
