How to choose between single-bin ball mill and multi-bin ball mill

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
