The energy required for crushing rocks was obtained by direct measurement of crusher's motor power during the crushing of samples. Laboratory tests were used to determine the following physical...

The selection or sizing of a crusher is much helped by measuring the rock's hardness during engineering. The various types of crushers in full scale mineral processing production include …

this basis, the specific crushing energy value E jv was determined in the process of vibratory crushing, calculated from the following relationship: 𝐸𝑗𝑣= 𝐾 [kWh/Mg] (1) where: E jv – specific energy of vibratory crushing, [kWh/Mg], P K – active power during crushing, [kW], Q – total efficiency (yield) [Mg/h].

Most of the costs in open pit quarry operations occur in crushing and grinding processes. Therefore, the management of crushing–grinding processes is very important. Many researchers investigated the effects of pile size distribution and specific charge values occurring as a result of blasting on crusher energy consumptions and provided …
