The Mk IX Rollo-Mixer® Batch Coater was originally designed to evenly spray two-part polymer epoxies, resin and hardeners onto a wide range of substrates - from sand to 40 mm spheres. Today's leading manufacturers of polymer coated slow release fertilizers use the Continental Rollo-Mixer Mk IX Batch Coater for even dispersions of two-part polymers onto a wide variety of fertilizer substrates. Microfilm layers are uniformly applied to the entire surface area of urea, mini urea, and NPK fertilizer products. It has a different coating/mixing action that creates a dynamic rolling bed compared to traditional Rollo-Mixers, which create rivers of material that constantly divide & combine. The Mk IX batch coater is available in both pilot and production size units.
