Cement grinding Vertical roller mills VS ball mills
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 015020 EUR per ton of cement For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, ie whether hardfacing is appliedWhether it’s lower grinding efficiency, higher energy costs or increased risk of equipment damage, excessive wear of your vertical roller mill (VRM) means trouble But with our insitu hard facing services, you can keep that trouble at bay with optimum wear protection for optimum mill performanceInsitu hard facing services for vertical roller mills |
Guidelines For Applying Hardfacing Alloys Hardface
Choosing a hardface overlay A Never put a soft, ductile weld metal or a workhardening manganese alloy on top of a harder, more brittle hardfacing alloy Deposits may spall and come loose The softer alloy should always be applied beneath the harder deposit Never use 7018 as a cushion or buildupJune 06, 2011 offers a technique to hard face a vertical roller mill giving the plant a shorter downtime Hardfacing costs only about a third of changing the wear parts and can be done in half the time In a joint venture with Welding Alloys, hasHardfacing a vertical roller mill
