Aggregate Crushing Value Test The Constructor
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of aggregates indicates its strength Lower crushing value is Crushing is one of the most energyconsuming technological processes The purpose of grinding is to achieve the desired grain size of mineral raw materials The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the Influence of Natural Aggregate Crushing Process on Crushing
