Comprehensive Guide to Disc Granulators

Disc granulators, also known as disc pelletizers or pan granulators, are essential equipment in the fertilizer production industry. They are designed to convert powdered materials into uniform, round pellets, which are crucial for efficient transportation and application. This guide will delve into the technical features, types, and applications of disc granulators, providing a thorough understanding of their significance in fertilizer manufacturing.

Technical Features of Disc Granulators

Disc granulators utilize a non-pressure (tumble growth) approach to agglomeration. The process involves tumbling materials on a rotating disc while continuously adding a binding agent and feedstock. This method allows for the creation of uniform pellets through a coalescence action, where smaller particles stick together to form larger ones. Below is a comparison table highlighting the key technical features of disc granulators.
