A. Recovery of secondary and usable zinc from top dross can be possible by practising in simple furnace by heating the dross ingots, fluxing and casting process. We have carried out lot of trials and have come up with more than 85% recovery with 99% zinc purity. Abhijit Nandan Calcutta, India. September 8, 2009 . Q. Dear all, I am very new to this field of study am only starting to use ...
It is a ball milling process where a powder mixture placed in the ball mill is subjected to highenergy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method, termed mechanical alloying, could successfully produce fine, uniform dispersions of oxide particles (Al

· re VRM vs Ball Mill for Cement Grinding. Specific power consumption high for ball mill and Low for VRM ; Maintenance costs high for VRM and low for Ball mill ; Process control/process technology ball is operation friendlt and simple in operation but VRM requires some PID or control technology. Plant/system auxiliaries less auxillaries in ball mill and hydraulic circuit to be maintained .
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

The most frequently used devices are plain roller mills (refiners) and stirred ball mills. Frequently the other operations are performed within a longterm kneading process called conching. Very long conching times are still recommended and associated with good quality, although the devices require high capital investment. One of the major progresses established in the last 30 years was to ...

Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls. The size reduction is actually to make the too large to be used solid materials usable. It leads to an ...
