Power saving up way of crushing of strong ores
The way of an optimum loss of strength and crushing of the strong ores is experimentally proved, allowing to provide economy of energy at crushing, decrease of the charge of metal at the expense of decrease of deterioration of metal parts of crumbers, increase in an exit of a useful component (taken metal) by application of optimum duration of affecting on ore of the microwave oven of waves. Difference of a way consists that before crushing subject ore to affecting of the microwave oven by electromagnetic waves with different duration. Irradiated with the microwave oven waves each small group and small group in not irradiated condition separately comminute in an impact tension machine by means of a free-fall cargo and define specific power consumption of crushing of ore for each duration of the microwave oven of affecting and an initial state. From the schedule «specific power consumption of crushing - duration of a time of affecting of the microwave oven of waves» define optimum value of duration of affecting of the microwave oven the waves, matching to the minimum value specific power consumption of crushing of the given ore. Behind that on the installed optimum duration of bombarding radiation of the microwave oven waves affect ore and a mineral of the given type and a size of the pieces which are subject to crushing, after bombarding radiation of the microwave oven by waves ore or mineral crushing spend in percussion crumbers.
