Zinc and lead ore ball mill liners adopt customized tooth design, which can effectively improve ore dissociation degree and mineral processing efficiency. The specific principles are as follows:
Optimize the motion trajectory of the steel ball: Customized tooth-shaped liners can change the motion trajectory and state of the steel ball in the ball mill. For example, the peak-biased wedge-tooth liner is designed with staggered wedge teeth on the long trough side of the steel ball lifting belt, so that the steel ball is subjected to more complex forces during the operation of the mill, thereby hitting the ore at a more reasonable angle and speed, and enhancing the impact crushing effect on the ore.
Enhanced grinding effect: The tooth shape design can increase the friction between the liner and the steel ball and the ore. For example, the one-piece liner adopts a waveform with a tooth shape design, which can improve the liner's ball carrying capacity, so that the steel ball can fully contact and rub with the ore during the lifting process, increase the grinding capacity per unit time, and help to more fully separate the useful minerals from the gangue minerals in the lead-zinc ore, and improve the ore dissociation degree.
Reduce liner wear: Reasonable tooth shape design can reduce the cutting wear of the steel ball and material on the liner. For example, the wedge tooth design of the biased peak wedge tooth liner plays a shoveling role on the material and steel balls, thereby reducing their cutting on the liner body, avoiding premature eccentric wear of the liner, extending the service life of the liner, reducing the downtime caused by replacing the liner, and thus improving the ore dressing efficiency.
Adapt to different ore properties: The hardness, particle size and other properties of zinc ore and lead ore may be different. The customized tooth shape design can be optimized according to the specific ore characteristics. For lead-zinc ores with higher hardness, a tooth shape with stronger impact force can be designed to better crush the ore; for ores with finer particle size, a tooth shape that is conducive to fine grinding can be designed to improve the grinding effect, ensuring that better ore dissociation and ore dressing efficiency can be achieved under different ore conditions.
