In June Welding Alloys UK undertook a project to repair a Vertical Roller Mill (VRM) at Hanson Cement’s site in Purfleet, Essex.The work involved the repair of a Loesche 46 2+2S VRM grinding table and rollers, which had worn after processing over 3,500 tonnes of granulated blast furnace slag.
INTERNATIONAL CEMENT REVIEW MAY 2012 V RMs have become the grinding circuit of choice in cement plants for raw meal, clinker and coal grinding due to their lower capital cost and energy consumption compared to ball mills.
LM Vertical Grinding Mill integrates five functions of crushing, grinding, powder selection, drying and material conveying.
Mineral grinding mill of HCM -HLM Vertical roller mill 〖 Product fineness 〗： 22-180μm 〖 Production capacity 〗： 5-700t/h 〖 Grinding filed 〗： It aims at all kinds of nonmetallic mineral materials with Mohs hardness below 7 and humidity within 6%.The mill is widely used in electric power, metallurgy, cement, chemical industry .
The grinding roller is the main grinding component of the vertical roller mill.The roller shaft supports the roller body through the double row spherical roller bearing and the cylindrical bearing roller bearing.The shaft end is equipped with a grinding roller bracket, and the grinding roller rotates around the roller shaft during operation.
The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill.Therefore, ease of replacement and regeneration is a major feature of the mill.The MVR mill has a modern hydraulic system used in operation and for maintenance alike.
The second stage of crushing and VRMs replaced a traditional SAG mill, ball mill and pebble crushing circuit.OZ Minerals explained in the study: “Vertical roller mills are widely used in the grinding of cement plant feeds and products, slag, coal and other industrial minerals, with thousands currently in operation worldwide.
Vertical cement mill operation is simpler and has a longer service life.It is a little bit different from the cement ball mill, the VRM cement mill is mainly composed of a separator, grinding roller, millstone, pressurizing device, reducer, motor, shell, and other parts.
Vertical Cement Mill: A vertical cement mill is used for the finish-grinding of cement.Its grinding table liners and roller sleeves are made from wear-resistant hard facing material or ceramic material.
Vertical mill for separate grinding process in cement.
