Metal Rolling

Roll materials vary dependent upon the specific metal rolling process. Common roll materials are cast iron, cast steel, and forged steel. Forged rolls are stronger and more rigid than cast rolls but are more difficult to manufacture. In industrial metal manufacturing processes, rolls are commonly made from nickel steel or molybdenum steel alloys.

On a roll: Examining the principles of roller compaction

12-12-2018Roller compaction is a method of powder compaction of dry powders into a solid mass known as the ribbon. This process is achieved by feeding powder through a set of directly opposed, counter-rotating rollers. The process avoids the use of liquids and high temperatures. The ribbon is broken down into a specific granule size via a milling system

Alternative Powder Processing Methods

Roll Compaction . Roll compaction, or powder rolling, is a process that can manufacture continuous lengths of metal strip, or sheet, from powders. Powder stock is fed into the gap between two rotating rolls. This is usually performed cold. The powder is compacted into a sheet and pushed forward. It then travels into a furnace where it is sintered.

Understanding The Dry Granulation Process

The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules.
