    These crushers use impact rather than pressure to crush the material. Used for sand, gravel and various materials. Crushing rock produces large amounts of dust. It is not uncommon for rock crushers to contain a water system with nozzles to lightly spray the rocks prior to crushing. However, this does not completely reduce production of dust.

    The preceding analysis indicates that an increase in drilling and blasting energy can increase the efficiency of total energy in the whole size reduction system. Moreover, a total of 210 blast tests show that the specific surface created by blasting in the unit of cm2g linearly increases with an increasing specific energy consumption in the unit of Jg, where g is the grams of the rock 22. Therefore, to attain optimum fragmentation, it is one of most important measures to increase the specific charge in blasting.

A successful blast has to meet two basic conditions 1 the explosive in each blasthole is completely detonated, and 2 detonator position, charge length, initiation plan, quantity of detonators in each borehole, delay time, and so on are correct, regardless of the types of detonators. As we can see, a successful blast is not an optimum blast yet since it does not consider stress wave superposition or energy efficiency. These will be considered in the following.
