In the present work, focus is on the production of nano-sized talc particles in a stirred ball mill and their nano talc particles incorporated in the polyamide-6 polymer matrix to form polyamide/talc nanocomposite. The results show that enhancement in the polyamide/talc nanocomposite strength properties such as flexural and tensile strength.

Talc Grinding - 911 Metallurgist

As the grinding progresses, the inefficiency increases: the most active grinding is done in the first hour, for the fine talc gradually cushions the impact of the pebbles and little grinding is done at the end. In one mill 5000 lb. of pebbles are used to one ton of talc in a mill revolving for 5 to 7 hr. at 22 r.p.m.

Method of assessing ball mill health - SAGMILLING.COM

test. This isn't reported in a standard ball mill work index test, but the method of Levin, 1989, can be used to calculate a "Levin B value" which is the kW·h per revolution of a Bond laboratory ball mill. Dividing ball mill grindability (g of product/rev) by the Levin B (kWh/rev) gives the desired units of measurement (g/kWh).
