in achieving the fine product size. It is understood that jet milling can be more effective than ball milling if the optimum parameters are followed, as recommended in the study; such as feed rate, pressure, feed size, and the liner used in producing the metallurgical powders TiC, TaC, WC, or a combination of any of these.

Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Air jet mills have mainly been developed for producing fine particles of below 50 mm. Most models are available in many sizes from labsize versions (as low as to 1 gram/h) up to industrial versions (up to 6 ...

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.
