What is the principle of roller compaction?

Question

Accepted Answer

Roller compaction is done by using a machine to compact small powders into solid forms such as flakes or sheets. When you need to compact something without the use of liquids, you can perform a process known as "dry granulation." To make the machine operate, the powder is introduced into an area between two anticlockwise rotating rolls. The rolls apply a fixed amount of pressure to the powder, which compresses it into a dense solid state. The roller surface, roller diameter, material being processed, feed screw speed, independent force, peripheral speed, and pressure capacity are some of the most significant factors that influence the efficiency of the compaction process. The content is mainly compressed in the nip region, where the rolls apply a significant amount of pressure on it to make it a solid strip. The string is then granulated using a mill or a granulator. The process is inexpensive and can be expanded, hence widely utilised in industries such as food manufacturing and pharmaceuticals.
