The ball millliner and grinding medium are directly contacting with the ore particles which affects the movement state of the grinding media and the ore particles and affects the grinding effect. Among the influence of the ball mill lining on the grinding effect the most important one is the influence of the material and the liner’s shape on grinding effect.
The influence of ball mill liner material on grinding effect:
Ball mill liner’s materials include stone, metal or alloy, wear-resistant rubber and others. When the liner is stone, the wear-resisting degree is small, and the abrasion is large. The liner needs to be change frequently and its service life is no more than eighteen months. When the ball mill liner is metal or alloy, the wear-resisting degree is big and the deformation ability is weak, so the grinding effect is the best and service life can reach two to three years. When the ball mill liner is wear-resisting rubber, the deformation ability is strong and the impact on steel balls and grinding will produce certain buffer effect, therefore, the general grinding effect is weaker than metal plate while better than stone.
The influence of ball mill liner’s shape on grinding effect:
The shell’s liner affects the grinding performance most. According to different shapes, ball mill liner can be divided into parallel liner, corrugated liner, ladder-type liner, hemispherical liner, convex prismatic liner, etc. When the shape of the liner is relatively flat, steel balls will do falling movement in the shell and the effect is mainly from grinding, then impact; when the shape are waveform and concave steel balls do dropping movement and the effect is mainly from impact, then grinding, this kind of liner has good effect in grid ball mill.
Study shows that, compared to high manganese liner, Xinhai’s wear-resistant ball mill liner has similar effect while its energy consumption can reduce by six percent and steel consumption can be reduced about eight percent; its service life can reach three to four years which is a big leap in ball mill industry and it is an ideal ball mill liner to numerous customers.
Wet ball mill is working at the situation where the water content is higher. The concentration in the wet ball mill is about 30 percent to 50 percent. ... [more]
