The Hardinge Mill is adapted to the complete finishing of limestone mixtures, coal and cement clinker, in one operation. To accomplish this with a good output, it is advisable to crush the feed to 3/4″, or preferably 1/2″ in size. This will allow the use of balls ranging from about 1 1/2″ in diameter to 3/4″, and will give a large ...

The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements. When the grinding media contacts different shapes of ball mill liners, the movement state will also change, thus enhancing the crushing ...
