Calcium Powder in Asphalt and Concrete

Calcium Powder in Asphalt and Concrete


Recently, on the one hand, most of the domestic mine crushing and industrial sand making plants produce a large amount of limestone powder waste (high content of limestone powder) in the production process, which not only pollutes the environment but also wastes raw materials, so how to turn waste limestone waste into treasure is important. On the other hand, domestic researches show that the use of limestone powder as admixture in concrete has the effect of improving concrete structure, enhancing concrete workability, and improving the resistance of concrete to sulfate attack at low temperatures.

SBM can provide you with a total solution for the limestone powder preparation system. As a manufacturer of grinding equipment, SBM has established hundreds of limestone grinding production lines in more than 120 countries and regions.


MTW Trapezium Mill is designed for pulverizing minerals into 80-425mesh of particles.

Input Size: 0-50mm

Capacity: 3-50 tons / hour

Applicable materials: silica, feldspar, calcite, talcum, limestone, dolomite, barite, gypsum, bentonite, fluorite, clay, etc.

Equipment Advantages

(1) Under the same output, the investment amount is only one-half of the ball mill, and the floor space is only equivalent to one-third of the 4R Raymond mill.

(2) A dust collector used. The dust removal efficiency is above 99%.

(3) A water flushing system used. After rinsing, the sewage is clarified and discharged into the wastewater ditch.

(4) Low noise. The grinding rollers don’t contact with the grinding ring, so the machine vibration is small and the noise is low.
