JYS Foundry For All Types Ball Mill Parts

Ball mill plants are widely used in the metal scrap crushing, mining crushing machinery, and chemical, cement and power generation. JYS advanced wear resistant material technology co.;ltd are specialized in manufacturing ball mill parts over 30 years, such as ball mill liner and steel ball.

JYS Foundry Ball Mill Liners

JYS advanced wear resistant material technology co.;ltd supply ball mill liner by customer drawings, and also cooperation with some ball mill manufacturer to develop technology for prolonging the wear and working life. The mainly materials included high manganese, alloy steel or others which customer need.
