Compression of powders and granules into cohesive mass is a complex and irreversible dynamic process. Mechanically, the compaction process consists of progressive strain on the powder mixture confiding it to a final volume and porosity. Compression of pellets into the tablet form is more complex. It should be taken into consideration not only pellets properties (their compressibility, shape, po...

A flowsheet model for a continuous direct compression tableting process is developed and applied to process data. The model contains powder feeding, blending and tablet compaction unit operations. The dataset was provided by Merck & Co., Inc., Kenilworth, NJ USA using a GEA ConsiGma continuous direct compression process designed for a 50 kg/h throughput using a six ingredient, potentially comme...

In present research, the foam glass-ceramic composites fabricated by window glass, steel slag and SiC, CaCO3 foaming agents were investigated by press–sintering method. The optimum sintering temperature was obtained at 1200°C with a 3-minutes holding time and 20°C/min heating rate. The optimum pressure level of 80 MPa for achieving the 70 % of relative density was selected. The effec...

The compaction method of powder metallurgy technology is an important process in influencing the density and hardness resulting product. This study aims to determine effect a one-way compared two-way on composite experimental for making aluminum matrix composites with silica sand reinforcement applies pressure 4500 Psi. Mixing utilizing mechanical alloying used horizontal ball mill machine. tes...

Particle size enlargement is the process of transforming fine particles into larger particles by the introduction of external forces, and is a value-added step in many processes involving powdered materials. There are many different reasons to enlarge particle size, including increased flowability and improved product shape and appearance. With the multitude of options available to achieve enla...
