Roll press for compaction of powders e.g. potassium slag - uses two rolls with peripheral ribs which mesh together to provide high compaction forcesThe press consists of two rolls driven in opposite directions of rotation and sepd. by a narrow gap, through which the powder is compelled to ...
This paper presents a study of a roll compaction process as a dry granulation method for typical food materials such as maize powder. This process is widely applied in industry as it can continuously produce large quantities of granular product at comparatively low cost. The objectives of this wo...
roll compactioncold rollingsinteringRoll compaction is a powder metallurgy process that has the potential for cost reduction in the production of titanium parts. In this study, experiments were carried out to investigate the effects of powder type and size on the roll compaction and subsequent ...
The powder rolling process for the manufacture of Ti-Al foils is described. Mixtures of the elemental powders (Ti + 50 at% Al) are compacted within the roll gap to form green strips with 70 mm in width and 0.7 to 1.2 mm in thickness. These green strips that can be worked easily and...

The primary motivation for this work...
A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds. An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum ...
