Procedure of Aggregate Crushing Value Test. Put the cylinder in position on the base plate and weigh it (W). Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod. Care being taken in the case of weak materials not to break the particles and weigh it (W1).
This means that the crushing process configuration is very important, because the crushing process as a matter of fact adjusts the correct feed to the crusher. If some of the operational parameters of crusher cannot be optimally selected for product shape, the adjustments to feed curve can compensate the shortcomings in these parameters.
A crusher is a major investment, so its essential to select one with the potential to meet your needs into the future. This guide covers a few of the key points to consider before making a decision. But remember that your crusher is just one part of a wider process always consider crushing in conjunction with screening and transport.
Rock quarries usually operate for at least 30 years and are developed in distinct benches or steps. A controlled explosion is normally used to release the rock from the working face. It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening stages to produce a range of final sizes to suit ...
