Can Dolomite Powder Be Used as Asphalt Mineral Powder? How To Produce Dolomite Powder Asphalt Filler Through Dolomite Grinding Mill?


Release date: 2023-02-03 17:05:21

Can dolomite powder be used as asphalt mineral powder? The asphalt filler generally requires the mineral powder obtained by grinding the hydrophobic stone such as strong basic rock in limestone or magmatic rock. In some areas lacking mineral powder resources, it is one of the necessary work to select some fillers to replace mineral powder. Lightly burned dolomite is an important auxiliary material for steelmaking, which contains a large amount of CaO and MgO and belongs to alkaline material. The hydrophilicity coefficient and heating stability of light burned dolomite powder meet the standard of asphalt filler, which can improve the high-temperature performance and water stability of asphalt concrete, and can be used as asphalt filler. So, how to produce dolomite powder asphalt filler through dolomite grinding mill? As a manufacturer of dolomite grinding mill machine equipment, HCMilling(Guilin Hongcheng) will give you detailed answers below.

The asphalt filler is composed of 20~40wt% light burnt dolomite powder and 60~80wt% mineral powder. During preparation, the light-burned dolomite powder is separated, and 100% of the light-burned dolomite powder<0.6mm is collected, and then mixed with the mineral powder in proportion through the metering and mixing device. How to produce dolomite powder asphalt filler? At present, light-burned dolomite is mostly made of 20~100 mm massive dolomite and calcined at 700~1200 ℃. Dolomite needs to meet the particle size requirements of mineral powder to be used as asphalt filler, which needs to be supported by a machine for grinding dolomite powder. HCMilling(Guilin Hongcheng), as the manufacturer of dolomite grinding mill, our dolomite Raymond mill, dolomite vertical roller mill and other dolomite grinding mill equipment can be used for the production of dolomite powder asphalt filler. It can process 80-600 mesh dolomite powder to meet the production requirements of dolomite asphalt filler.
