In the chemical industry, granulation refers to the act or process of cutting or chopping large objects and remelting them into particles or pellets. The roller type extrusion granulator centers on two counter rotating rollers and is supported in the frame by spherical self-aligning roller bearings. In addition to the radial load, the bearing can also bear two axial loads, making it insensitive to shaft deflection during operation.
The granulation process combines one or more powder particles and forms granules that will allow the tableting or spheronization process to be within the required limits. In this way, a predictable and repeatable process can be achieved, and a roll pelletizer can be used to produce high-quality tablets or granules. Therefore, the roller press granulator is an important organic fertilizer machine (https://m.hqhifertilizermachine.com/products/) in the fertilizer processing industry.
