Chocolate Grinding Attrition Mills
The material to be ground is placed in a stationary, jacketed tank with the grinding media. Carbon steel, stainless steel and chrome steel balls (3/16″ or 1/4″) are commonly used media. The material and media are then agitated by a rotating internal shaft with arms. The final result is a fine, even particle dispersion.

Ball Mill Loading
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23% ...

The working principle of ball mill
22/05/2019 · The larger the ball to material ratio, the higher the grinding efficiency. But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties (Figure 82). The ball ratio is usually selected from 2:1 to 5:1.

Ball Mill Refining
Our Ball Mill's unique redesigned grinding vessel features a milling chamber with almost no deadspace. Less product in the ball mill during grinding ensures optimum grinding efficiency, better temperature control, and leads to a reduction of waste during product changes. This generation ball mill is the most effective by far.
