The chamber diameter tests were performed at the same stirrer design, media size and media filling. The studies concluded that, the use of larger chamber improved the grinding efficiency since 31.8% and 35.8% less energy was consumed than the smaller mill at the RR d50 of 1.41 and 1.66 respectively. This behaviour of the larger …

In the Horizontal Developing Chambers, HPTLC plates can be developed from both opposing sides towards the middle. This permits the number of samples to be doubled as compared with development in a tank, provided the separation distance of 45 mm, i.e. 50 mm minus 5 mm distance from the edge, is sufficient. This chamber type is …

where m = M 1 is the mass of the solid, kg; l is the chamber length, m; E = 2 × 10 11 Pa is the elastic modulus of the chamber wall; and J = 0.75 × 10 −5 m 4 is the moment of inertia of the chamber cross section.. When the mass of the grinding bodies within the chamber is М 1 ≈ 12 kg, we find that τ = 0.5 × 10 −3 s. Taking into account …

The grinding chamber is loaded with a set of grinding bodies— for example, balls of diameter 3–10 mm. Each vibrational drive permits regulation of the speed and direction of rotation. When the drives are switched on, the grinding bodies in the chamber perform complex spatial motion relative to their own centers of mass, the …

In order to get further information about the distribution of the local specific energy in the grinding chamber, the flow pattern in the chamber was calculated numerically. The calculations are restricted to a stationary operation of a stirred ball mill in the absence of grinding media when laminar stirring of a Newtonian fluid takes place.
