Nov 19, 2020 one factor initiating the wet granulation process is the provision of combining liquid to the bed [26]. drum [27], disc [28,29] and vibrating [30] granulators are well known. at the same time, during disc or drum granulation, apart from the agglomeration process, an impact e ect of granules

granulation is a size-enlargement process by which small particles are bonded, by means of various techniques, in coherent and stable masses (granules), in which the original particles are still identifiable. in wet granulation processes, the powder particles are aggregated through the use of a liquid phase called binder. the main purposes of size-enlargement process of a powder or mixture of

Analysis and treatment of common malfunction of granulator

In this paper, based on the theoretical knowledge of the production process of plastic granulation and the management experience of more than ten years of actual production operation, this paper analyzes and judges the common causes of the failure in the operation of the unit, and makes the corresponding solutions and treatment methods so as to ensure the long and stable operation of the unit.

the temperature of the granulator barrel, the amount of granulation liquid added and, to a lesser extent, the powder feed rate were the parameters influencing the solid state of the active pharmaceutical ingredient (api). a higher barrel temperature and a higher powder feed rate, resulted in larger granules.
