In the grinding process of building materials, metallurgy, chemical industry and other industries, the selection of ball mills directly affects production efficiency and energy consumption costs.The core difference between a single-warehouse ball mill (single-cylinder) and a multi-warehouse ball mill (multi-cylinder) lies in the hierarchical grinding mechanism: the former mixes and grinds materials, while the latter realizes coarse grinding and fine grinding segmented processing through the compartment plate.

1. Applicable scenarios of single-warehouse ball mill

    Raw material characteristics: suitable for materials with low hardness and single particle size requirements (such as limestone and pulverized coal)

    Process requirements: scenarios where rough grinding needs to be completed quickly or the uniformity of finished particles is not required

    Cost advantage: simple structure, low maintenance cost, suitable for small and medium-sized production lines

2. Technical advantages of multi-warehouse ball mill

    Graded grinding: Through 2-4 warehouses, the progressive processing of "coarse grinding →fine grinding" is realized, and the grinding efficiency is improved by 20%-30%.%

    Finished product control: can meet different fineness requirements at the same time (such as mixing and grinding clinker and gypsum in cement production)

    Energy-saving performance: The materials are layered according to particle size in the warehouse to avoid excessive grinding, and the power consumption per ton is reduced by about 15%.

3. Selection decision tree

    If the hardness of the raw material is >Mohs level 6 or multi-stage grinding is required→ choose the multi-warehouse type

    If the daily processing capacity is <500 tons and the fineness fluctuation of the finished product is allowed → Priority single warehouse type

    It is recommended to configure a closed-circuit system of multi-warehouse ball mill + powder separator for the new production line
