Modifications to Johanson's roll compaction model for improved relative density predictions
Liu, Yu. M.S.M.E., Purdue University, May 2016. Modifications to Johanson’s Roll Compaction Model for Improved Relative Density Predictions. Major Professor: Carl Wassgren, School of Mechanical Engineering. Johanson’s roll compaction model [J.R. Johanson, A rolling theory for granular solids, ASME Journal of Applied Mechanics E32 (1965) 842–848] is modified to improve its predictions of a compa...
متن کاملCompaction Behavior of Isomalt after Roll Compaction
The suitability of the new isomalt grade galenIQ™ 801 for dry granulation and following tableting is evaluated in this study. Isomalt alone, as well as a blend of equal parts with dibasic calcium phosphate, is roll compacted and tableted. Particle size distribution and flowability of the granules and friability and disintegration time of the tablets are determined. Tensile strength of tab...
متن کاملHigher Green Strength and Improved Density by Conventional Compaction
A new material system that can produce very high green strength and green density has been developed for conventional compaction processing. The system, which uses a zincless lubricant, is based on the optimization of the bonding mechanism and binder chemistry. This approach permits the bonding of copper particles in a FC-0208 mix. Examples of the binder-treatment of FN-0208, Ancorstee145P, and...
متن کاملComparative Study of Different Binders for Roll Compaction/Dry Granulation
H. Mangal , M. Kirsolak , B. Ehlig , P. Kleinebudde 1 1 Heinrich Heine University, 2 Nisso Chemical Europe GmbH Purpose Tablets produced from granules, which were obtained by roll compaction/dry granulation show reduced tensile strength compared to tablets produced by direct compression or after wet granulation. This emphasizes the importance of binders for this application besides their genera...
متن کاملNumerical Methods for Predicting Roll Press Powder Compaction Parameters
Large numbers of cohesive powders are compacted using a roll press. The principle of compaction is that particulate materials become a compact when they are subjected to high pressure. Experimental work was carried out on pharmaceutical powders [1] to determine the influence of operating parameters on the roll process compaction. Theses parameters are determined for a given powder and must be m...
