Grinding and granulation in a vibratory ball mill ...

In the grinding of paracetamol, lactose and sucrose in a vibratory ball mill, it is found that an equilibrium is rapidly attained due to the agglomeration of ground particles. The existence of this agglomerative phase of comminution has been extensively reported in the literature. This study investigates prolonged vibratory ball milling as a means of pharmaceutical granulation. The granules ...

Vibration Mill: Components, Advantages and Disadvantages ...

2016-01-11  Vibration mills are similar to ball mills in that particles of the materials are crushed between porcelain or metal balls and the mill body. Drugs and excipients are readily ground to less than 5 mm, the grinding time being considerably less than is required in normal ball milling. As a result, the efficiency of the comminution process in vibratory milling is a good deal than it is in ...
