shape wise classification of aggregates,shape of aggregates can get influenced by not only the characteristics of parent rocks but also by the type of crusher used to crush the rocks. most of the jaw crushers with plain jaws will give flaky aggregate, while with footed jaws will give cubical ore. but it is the cone crusher which will give perfectly cubical aggregates. also read:.size reduction (giki) - slideshare,classification of crushers • it is not generally economical to effect a large reduction ratio in a single machine. • the equipment used is usually divided into classes as given below, according to the size of the feed and the product. • a greater size reduction ratio can be obtained in fine crushers than in coarse crushers 13..soil classification and identification (with diagram),fine grained soil: following field tests are performed to classify fine grained soil or for the fine fraction of coarse grained soil (i) dilatancy test: prepare a part of moist soil having a volume equivalent to a 25 mm cube by adding enough water to make the soil soft but not-sticky. place the pat in the open palm of one hand and shake.lecture 4. aggregates - aalto,• the material is crushed with cone crushers, jaw crushers, hammer mills, or pug mills and is screened for size. oversized material is returned to the crushers, and the material that passes through the screens is transferred to the storage. • from the storage, the material is fed to a rotary kiln, which is fired with coal, coke, natural.
