Mill Liners:Ball Mill Liners, SAG/AG Mill Liners, Rod Mill Liners
ZTIC specialized in producing wear-resist castings used in grinding equipments and main spindle bush, brake shoe for the mill of various specifications. It has strong casting, heat treatment and machining ability, strict quality and process controlled methods as well as the perfect examination and experimental means, so that can wear-resisting products enjoy high reputation in China and sells well all over the world.
GENERAL DESCRIPTION
Grinding wear parts are subjected to different combinations of impact and abrasion, as they are used in SAG/AG, ball or rod mills. Our wear parts are manufactured to the highest standards of quality, traceability and delivery, ensuring high levels of reliability for our customers. Also, our wear parts add value to customers' processes through customized designs The use of internationally recognized advanced specialized software simulation mill liners for lining structure, size to optimize the design.
Barrel and cap are made of wear-resistant liner material chrome molybdenum alloy steel, the use of convex liner, improve service life and grinding effect.
Liner with a flat head bolts, supporting self-locking nut and ferrule. Coupling bolts with special seals to prevent leakage of plasma.
Quantity bolted liner wealthy amount of 5%.
Cover and cylinder liner wear-resistant rubber padding junction strip, which is fixed by the close of the liner.
Rubber gasket between the cylinder liner and a thickness of 6mm, noise can be reduced.
