Ball mills grind various ores and other materials either wet or dry. There are two kinds of ball mills, grate type and overflow type, due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, including Hardened steel, stainless steel, ceramic, flint pebbles.
Ball mill. According to the discharging way, ball mills can be divided into two types: grate discharge type and overflow type. a. Grate discharge ball mill. The grate discharge ball mill can discharge material through a sieve plate, with the advantage of the low height of the discharge port, which can make the material pass quickly.

The mixer mill MM 500 nano is a compact, versatile bench-top unit which has been developed specially for dry, wet and cryogenic grinding of up to 2 x 45 ml sample material within seconds.
We particularly focus on the way balls diffuse axially within the mills. As can be seen in Fig. 8, the concentration of smaller balls is slightly high at the product end of the mill whilst that of bigger balls is slightly high at the feed end of the mill. This is evidence that liner configuration affects ball segregation inside the mill.
The rotation of the mill is driven by the motor, the power of which is determined by the mill's size and the grinding capacity. Ball mills can be as small as …
The Micro Ball Mill can grind 2*96 samples quickly and efficiently only with 1 -3min. The grinding jars of the GT300 perform horizontal oscillation in high frequency. The inertia of the grinding balls causes them to impact with high energy on the sample material and grind it. The movement of the grinding jars and balls
