Duralox is a registered brand name of a specially developed proprietary composite by Jyoti Ceramic from which ball mill lining bricks, wear resistant lining tiles, grinding media and other components are manufactured.
The true value of ball mill lining is determined by its length of trouble free service in relation to the mill's production output, irrespective of mill's type, size and shape. The criteria for selection of lining and grinding material must take into consideration not only the required output and expected service life, but also construction of ball mill, it's drive and motor power before switching over to materials of high density such as Duralox.
Duralox 92W mill lining bricks and grinding media have been developed by Jyoti Ceramic after many years of R & D with the intention of enhancing the former's performance. Duralox 92W lining bricks and Duralox 92W grinding media complement each other's performance and best results are obtained when both are used together.
Duralox ceramic mill lining bricks protect the steel ball mill shell and provide high purity grinding. Following features and benefits are worth considering while using Duralox Ball Mill linings for milling substances of hardness below 9.0 Moh's scale :
