In the mining industry there is the problem of the formation of oversize blocks rocks, which require secondary crushing. Using the combined method of electric crushing oversized to accelerate compared with the technologies using today, and automate this process. The main task in this method is a shift from the source industrial frequency power supply to the pulse of electrical energy. An important component is the switching time is necessary take into account the direction of the current flowing through the rocks. For these purposes the controller Arduino Uno, which allows to configure the switching power sources.
