Ball Mill Liner


CHAENG(Great Wall Machinery) strictly controls the quality of liner in processing and manufacturing to produce the best ball mill liner for customers.

First, the medium frequency electric furnace is used for the smelting of high quality scrap steel, manganese alloy and other alloy materials, the treatment of micro alloying, the hardening and tempering of quality, and casting with sand moulding

Second, the consent temperature pouring method is used to ensure the quality of products without sand, porosity and collapse.

Finally, automatic temperature-controlled annealing technology changes the inner structure of the liner and to further improve mechanical performance. Advanced spectral detection is used to ensure chemical composition and stable performance in front of furnace, after furnace, semi-finished products and finished products.
