High Energy Ball Milling Equipment | Lab Manager
The E MAX is designed specifically for high energy ball milling as it features a variable speed drive up to 2000rpm, and considering the high rpm levels also features an internal water cooling system that can also be adapted to an external chiller, thus eliminating down time from overheating.
Assessing the surface modifications following the ...
The decreased interaction of water with the surface on ball milling is thought to reduce the effect of site blocking whilst still providing a sufficiently high surface concentration of water to enable effective hydrolysis of the isocyanate to form ammonia and, thereafter, N 2.
What is ball milling process
Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine.
