Ball mill grinding system Mineral material grindability test method

1 Scope

This standard specifies the terms and definitions, test principles, test equipment, and sample system for the test method for the grindability of mineral materials in ball milling systems. Preparation, test procedures and test results. This standard is applicable to the ball mill grinding system of raw materials such as ore, medium ore and smelting products of metal and non-metal minerals. Determination of sex.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Ball milling index balmilworkindex Based on the index of FCBond's pulverization theory, it characterizes the ball-grinding wearability of mineral raw materials. 3.2 Feeding size thesizeofthemilfeed F80 The size of the square hole mesh when the feed rate of the ore sample is 80%. Note. The unit is micrometer (μm). 3.3 Product size thesizeofthemilproduct P80 The square hole mesh size when the grinding product pass rate is 80%. Note. The unit is micrometer (μm). 3.4 Cyclic load circulatingload In the material of the mill, it is necessary to return the ratio of the coarse powder quality of the mill to the fine powder quality of the finished sieve. 3.5 Equilibrium state After three consecutive grindings, the cycle load is consistent with (250±5)%, and the difference in the quality of the finished product per revolution of the mill is less than the average value.
