Overflow type ball mill ore discharge fineness

The fineness of the ore discharge of the overflow ball mill is also a key parameter. It is not only related to the grade of the concentrate, but also affects the smoothness of the entire production process.

1. The relationship between the fineness of ore discharge and the grade of concentrate

The fineness of the ore discharge of the overflow ball mill has a great impact on the grade of the concentrate, and the fineness is too coarse and the work is too fine, which will have a bad impact.First of all, too coarse particle size may not be able to separate useful minerals from gangue minerals, causing impurities to enter subsequent operations, which in turn affects the grade of the concentrate.

In addition, if the ore discharge is too fine, it may cause agglomeration in the subsequent flotation process, so that the material and the flotation agent cannot be in full contact, resulting in poor flotation effect, further affecting the grade of the concentrate.

2. The fineness of ore discharge affects the smoothness of the production process

Controlling the fineness of the ore discharge of the overflow ball mill within a reasonable range can ensure the smooth production process.After the overflow ball mill grinds the ore, the product is fed into the grading equipment for grading, usually in conjunction with a hydrocyclone.If the ore discharge is too fine and too coarse, it will inevitably cause a burden on the hydrocyclone, resulting in poor grading effect.Moreover, the subsequent production process will also be overburdened.

Conversely, if the ore discharge is too fine, it is prone to dust, which will not only cause environmental pollution, but may also have safety risks.At the same time, during the storage and transit process of excessively fine materials, due to the strong adsorption between their particles, they are prone to agglomeration, which affects the normal flow and transportation of materials, thereby interfering with the smooth operation of the production process.
