Biodegradable polymer coating for slow-release fertilizers
The need to coat a material is pervasive throughout many industries. A sophisticated finishing process, coating allows producers to control the handling, storage, and performance properties of a granular fertilizer product. The primary ways in which coating is used in this effort are summarized here. See more The coating drumconsists of a rotary drum which rotates at a defined speed while material is continuously fed into the inlet end. Set on a slight angle, gravity helps to move material through the drum according to a predetermined … See more Producers can spend years developing the perfect coating formulation for their product, but that does not mean it will work; the coating … See more Coating is an indispensable tool in producing high-quality granular fertilizer products that meet precise specifications. From improving … See more Achieving the perfect coating distribution often requires testing in a facility such as the FEECO Innovation Center. Testing allows a number of variables to be tested and fine-tuned to reach optimal product coating. Data points … See more symbol of electric potential energy
