Abstract: A method of and apparatus for the electrostatic coating of poorly or non-conductive materials such as pellets seeds and powders, in which the product material is set in motion, preferably turbulent or agitating motion relative to at least one electrostatic coating material spraying device which is directed toward the moving product and has applied thereto a high potential difference whereby the coating material is given an electrostatic charge and an electrostatic charge of opposite polarity is induced on the product causing electrostatic attraction between the coating material and the product. The invention is applicable both to continous and batch production of coated material and preferably involves moving the product past the or each spraying device in a plurality of spraying passes. Charged atomised liquid and diffused powder may be sprayed onto the product either in sequence or at the same time.
