Based on the absorption of advanced technologies of famous international corporations and 30 years’ experience in grinding mill production, LiMing has launched the LM Vertical Grinding Mill which integrates five functions of crushing, grinding, powder selection, drying and material conveying.
Heat and risk of contamination make it difficult to keep equipment up and running. Avoid premature bearing failure to increase reliability while reducing maintenance.
In vertical roller mills, high temperatures and high particulate concentrations make maintenance a difficult challenge for operators. Especially when trying to prevent the problems that can lead to bearing failure and costly unplanned downtime.
Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.
