Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

الحصول على السعرAmpere. Definition: The ampere (symbol: A), often referred to as simply amp, is the base unit of electric current in the International System of Units (SI). The ampere is defined formally based on a fixed value for the elementary charge, e, of × 1019 when expressed in the unit C, which is equal to A·s. The second is defined based on the cesium frequency, Δ ν Cs.

الحصول على السعرHow to Convert Kilowatts to Amps. For a single phase AC circuit the formula to convert kilowatts (kW) to amps is: amps = (kW × 1,000) ÷ volts. It is possible to find the amperage from kilowatts if you know the voltage of the circuit using Watt's law. Watt's Law states that current = power ÷ voltage. In Watt's Law, power is measured in ...
