Screening for size reduction
Performance of screens will fall back on three main parameters: Motion – Inclination – Screening Media Screening by stratification By building up a material bed on a screen deck the material will stratify when the motion of the screen will reduce the internal friction in the material. This means that the finer particles can pass [...]
Grinding for size reduction
Size reduction by crushing has a size limitation for the final products. If we require further reduction, say below 5-20mm, we have to use the processes of grinding. Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction, compression, shearing and attrition. The two main purposes for a grinding process are: [...]
Crushing ore and materials
In these operations the value is achieved at the fine end, say below 100 micron (150 mesh). Normally the size reduction by crushing is of limited importance besides the top size of the product going to grinding. This means that the number of crushing stages can be reduced depending on the feed size accepted by [...]
Size reduction process
Minerals being crystals have a tendency to break into endless numbers of sizes and shapes every time they are introduced to energy. The difficulty in size reduction lays in the art of limiting the number of over and under sizes produced during the reduction. If this is not controlled, the mineral will follow its natural [...]
