Classifiion of Aggregates Based on Size and Shape
Classifiion of Aggregates as per Size and Shape. We know that aggregate is derived from naturally occurring rocks by blasting or crushing etc., so, it is difficult to attain required shape of aggregate. But, the shape of aggregate will affect the workability of concrete. So, we should take care about the shape of aggregate.

Classifiion ScienceDirect
After initial liberation of a mineral constituent from its ore by crushing, grinding and screening, separation of minerals by size is normally attempted by a classifying process. In mineral processing operations, classifiion and separation of mixtures of fine and coarse particles and also of lighter and heavier particles may be performed in

As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. The reduction ratio is the ratio of crusher feed size to product size. The sizes are usually defined as the 80% passing size of the cumulative size distribution. For jaw crusher, the ratio can be estimated by the gape. CHAPTER 14. AGGREGATE PRODUCTION
