LM Vertical Grinding Mill integrates crushing drying grinding separating and transport. The structure is simple while the layout is compact. Its occupational area is about 50% of that of the ball-milling system. The LM grinding mill can also be arranged outdoors which greatly reduces the investment cost.

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.

Features of Vertical Pre-Grinding Mill: 1. Its grinding roller employs forced lubrication oil feeding mode to effectively prevent dust from entering into bearings. 2. Made of high-chromium cast iron, its lining plate of grinding disc and roller shell are easy to change and have a service lifespan more than 30000Hr. 3. The speed reducer is ...
