Size Reduction - Visual Encyclopedia of Chemical Engineering
Size Reduction Raw materials undergo size reduction through different mechanisms: impact, compression, and attrition One way to classify size reduction equipment is into crushers and grinders, where grinders produce finer particles than crushers
The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant Crushing is a dry process whereas grinding is generally performed wet and hence is more energy .
