3 Terms and Definitions
Terms and definitions GB/T 20565 established applicable to this section.
4 sampling and sample preparation
According to GB/T 10322.1 or SN/T 1797.1 sampling, according to GB/T 10322.1, GB/T 14202 and ISO 3852 in
Requirements for sample preparation.
5 measurement method
Bulk density using GB/T 14202, ISO 3852 method was measured in the absence of clear water conditions.
6 volumes of the lowest density value
Lump ore bulk density. 1.75t/m3
Ore powder bulk density. 1.60t/m3
Iron ore pellets bulk density. 2.00t/m3
Sinter bulk density. 1.70t/m3
Note. The bulk density is smaller than the minimum value, should not be used directly, it should be used in conjunction with high-quality ore.
