The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80% passed through a 3000 micron sieve. Further size reduction was completed in a 1.0 xx1.5m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the ommencement of grinding. Data: S.G. of the ore =3.86.
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance, resulting in high final fineness.
The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments. However, the best particle shape is found in material about the same size as the CSS, which is the smallest discharge openin…See more on kompletamerica
