Compaction of the steel powder is carried out using two high rolling mill. The schematic representation of the setup is shown in Fig. 1 (a). The rolling of powder is carried out with the permutation of process parameters viz. rolling speed of 15, 20, 25 rpm and rolling pressure of 700 – 1000 MPa with roll gap of 200 μm.

Roller presses are used to process bulk solids (powder, granules) in order to perform a dry granulation by compaction. They can typically produce a compacted sheet of material that is later milled, even if some models have specific rollers whose shape allows to produce some briquettes. This page is focusing on the design of roller presses, the mechanisms …

Dry granulation by roller compaction consists of two separate steps. The first step is an agglomeration step, starting From Raw Material Powder to Flake (1.2). The flake (also referred to as ribbon) is a tablet like band that comes out of the roller compactor. The poor flowing raw material powder is conveyed

Phase 1 investigated the effect of roll compaction force on the bulk powder properties, with the roll compaction force increasing from 3 kN/cm to 12 kN/cm in six discrete steps. Phase 2 studied the effect of changing the roll gap from 1.5 mm to 5 mm in six discrete stages. The mill mesh size was maintained for both phases at 1 mm.

However, powder processing is widely recognized as being challenging, with unit operations often exhibiting lower reliability and greater variability than those only involving liquids and gases. Different grades of powder are routinely specified as either feed or product in terms of composition and particle size alone.

The resulting inconsistent feed rate to the mill creates unwanted deviations in the milling process. This is especially significant when a mill is used with varying materials and can result in wide deviations in performance. The optimal material feeding method for a mill provides a reliable and consistent mass feed rate to the mill inlet.

The most important parameters in the dry granulation process are powder feeding, compaction pressure applied, and the gap diameters. The powder is fed into the rollers and – depending on the feed rate of powder, gap diameter and force – the powder will be 'compacted' into a pre-defined ribbon thickness.
