The pearlite ball mill cast iron has high strength and high wear resistance. In order to get the cast pearlite, Sn is added to the alloy solution during melting. Since Sn is an element that blocks the spherifiion of graphite, it is necessary to control the amount of Sn addition, which generally is less than %.

Mill (grinding)
Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material. In tower mills, there is no cascading action as in standard grinding mills. Stirred mills are also common for mixing quicklime (CaO) into a lime slurry. There are several advantages to the tower mill: .

Ball Mills
Cylindrical Ball Mills differ usually in steel drum design (Fig. ), which is lined inside by armor slabs that have dissimilar sizes and form a rough inside surface. Due to such juts, the impact force of falling balls is strengthened. The initial material is fed into the mill by a screw feeder loed in a hollow trunnion; the ground product is discharged through the opposite hollow ...

Cement mill
Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush .

Ball Mills
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a ...
