This standard specifies the following scope of ball mills and rod mills, their type and basic parameters, technical requirements, test methods, inspection rules, marking and instructions for use, packaging, transportation and storage.
This standard applies to ball mills and rod mills(Hereinafter referred to as mills) for grinding ores, rocks and other suitable grinding materials of various hardness in wet and dry processes.
2. Type of mills and basic parameters
2.1 Type of mills
2.1.1 Mills are divided into ball mills and rod mills according to different grinding media; ball mills are divided into grate type and overflow type according to discharge form, and grate type ball mills are divided into dry type and wet type. The structure type is shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5 respectively, and this figure does not determine the specific structure. Among them, Figure 1 discharge end cover structure is recommended for grate ball mill with diameter no more than φ3200mm, and Figure 2 discharge end cover structure is recommended for grate ball mill with diameter no less than φ3600mm.
