Abstract. The applicability of the vibratory ball mill to fine powder mixing is investigated using two model 1:1000 binary systems of microfine salicylic acid sucrose and milled tolbutamide with lactose. Mill performance is evaluated by measuring the extent of mixing relative to a specified standard and by comparing the rate of mixing to the ...

drum-type ball-mills tend to rely on impact as the dominant comminution stress. However, an increasing contribution of attri-tion should be sough as particle get smaller. This can be achieved, for example, in stirred bead mills [22] or vibratory finishing mills [5]. Thus, identifying the most energy-efficient mill geometry and

This approach is based on a hybrid numerical model of a 24-degree-of-freedom gearbox, simulating one gear train and two drive shafts. The impact forces of the mill drum are modelled by a discrete element method (DEM). The ball-filling rate (Fr), the mill speed (Nr), and the ball size (Db) are considered to study this phenomenon.
