MOP/KCL/ammonium chloride fertilizer powdered material auger feeding double roller hydraulic compacting dry granulating machine

Product Overview

Description

The dry granulation process is used to form granules without using a liquid solution because the product granulated may be sensitive to moisture and heat. Forming granules without moisture requires compacting and densifying the powders. In this process the primary powder particles are aggregated under high pressure.

Dry granulation can be conducted under this process: the powder is squeezed between two counter-rotating rollers to produce a continuous sheet or ribbon of materials.

 

When a roller compactor is used for dry granulation, the powders may not possess enough natural flow to feed the product uniformly into the die cavity, resulting in varying degrees of densification. The roller compactor (granulator-compactor) uses an auger-feed system that will consistently deliver powder
uniformly between two pressure rollers. The powders are compacted into a ribbon or a sheet between these rollers and milled through a low-shear mill.

Typical roller compaction processes consist of the following steps: convey powdered material to the compaction area, normally with a screw feeder, compact powder between two counter-rotating rolls with applied forces, mill resulting compact to desired particle size distribution. Roller compacted particle are
typical dense, with sharp-edged profiles.
