Screening for size reduction
Published on 2012-01-29 02:22:15
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 [...]Read more...
Grinding for size reduction
Published on 2012-01-29 02:20:20
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: [...]Read more...

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 [...]Read more...
