LM Vertical Mill

 limestone in concrete mix

High drying efficiency, Low running cost, Good environmental effect

LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly.

Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.

MTW Trapezium Mill

limestone in concrete mix

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

The effects of limestone aggregate on concrete properties

2010-12-1  According to the series of experiments, the following conclusions are obtained; 1. The fine limestone can reduce the drying shrinkage in concrete. However when it is mixed with the mountain sand, this reduction may vary from 12% to 15% and its behavior is not monotonous to the proportion of fine limestone in the mix.
