Abstract
A new device and process for continuously applying coatings, such as resin and additives or polymers or the like, to minerals are disclosed. The device and apparatus differ substantially from standard batch coating processes currently used by industry. The apparatus uses a horizontal cylinder with an internal auger and a series of injection ports distributed along the cylinder. Minerals that are to be coated are pretreated and passed through the mixing cylinder using the auger (which may comprise one or more screws with variable pitch blades). As the mineral particles pass through the cylinder various coating materials are injected by the injection ports. The complete system is described, the method of use is explained and the control system which allows for different products is described.
