ABSTRACT:
A screenless mill which grinds and simultaneously conveys material utilizes a grinding system constituted by a rotating shaft on which grinding elements are fixed in a helical arrangement. The helical arrangement forms a screw which facilitates the advancement of the material in addition to grinding it. The screw pitch is adjustable in such a manner that when the material reaches the discharge port it has attained the required particle size. The grinding elements are readily interchangeable to permit replacement of worn or damaged parts or to treat a variety of materials as well as to vary the degree of grinding to be attained.
