Effect of Z-164D on Grinding Efficiency of Oolitic Hematite and its Mechanism

Abstract:

The effect of Z-164D dispersant on the grinding efficiency of oolitic hematite was studied. The content of-0.074 mm in the ground product was increased by 30.15% by using Z-164D dispersant which weight was 2% of oolitic hematite compared without using any dispersant under the optimal technological conditions of the grinding aid experiment. It was considered that the content of-0.074 mm in the ground product was increased by 26.52% by using Z-164D dispersant which weight was 1%, so it was confirmed that the weight of Z-164D dispersant was 1% of oolitic hematite from the perspective of economic benefit finally. On this basis, the absorption characteristics of the Z-164D on the oolitic hematite surface which could change the pulp viscosity and the surface experience of particles were studied and the mechanism how Z-164D dispersant improved the grinding efficiency of oolitic hematite was revealed.
