The spares and wears are assumed to be steel, and were modeled as a 50/50 BOF/EAF mix. The power consumption of the rock crusher, normalized to the functional unit of 907 metric tons …

As the cards of a steam engine enable us to determine the power developed, and to locate faulty operation or design, so the crushing-surface diagram enables us to determine the power consumed, and to locate points at which the crushing practice may be improved and faults remedied in design. ... Fines were screened out …

For the sedimentary rocks (Siltstone) the specific crushing energy is approximately 1.26 kJ/kg. Tosun and Konak (2014) measured power consumption of jaw crusher during crushing of limestone rocks ...

The energy consumption was also influenced by the no-load mechanical energy of the cone crusher: the higher the speed, the more no-load energy …

For crushing and grinding equipment, these are: forces arising in the process of material crushing, torque, which directly depends on the resistance torque, and the required …

height of the crusher's working chamber h = 250 mm, the outlet slot er = 20÷30 mm, the angular velocity of the drive shaft (no-load running) n = 388 rpm, moving jaw displacement s ≈ 6 mm, gear ratio of V belt 3.2, rated engine power (type SZJe 34b) Nzn = 4 kW. The material used in the tests (feed) was a lime-

ble to determine this wasted power consumption, since existing formulas for the power of hammertype crushers take no account of the drag due to the dust– air suspension [4–11]. To determine the power N da (kW) consumed in overcoming the drag due to the dust–air suspension, we use the formula N da = Q daΔp/1000, (2) Power Consumed by a ...

H Power consumed by the crushers will directly affect productivity; and, The amount of energy applied per unit of feed (the crusher power rate) will affect product fineness.
