Technology of Processing Mineral Superfine Powder Used in High Performance Concrete by DHM Grinder and its Characteristics

Abstract:

In this paper, the requirements for processing equipments and technologies of mineral superfine powder used in HPC are analyzed. Mechanism and properties of DHM grinder and processing natural zeolite, slag and fly ash by DHM-160 grinder are investigated. Natural zeolite and slag achieve the fineness that 90% of which are smaller than 0.038 mm by DHM grinder. 99% of fly ash processed by it is smaller than 0.038 mm and 45% of that is smaller than 10 μm. Superfine powder processed by DHM grinder can meet the requirement of HPC, and its energy consumption is lower than using conventional equipments.
