creator Shutov, Fyodor creator Ivanov, George creator Arastoopour, Hamid A process and apparatus for pulverization of thermosetting, crosslinked thermoplastic and natural polymeric materials by applying normal and shear stresses by oppositely rotating meshing conical screws sufficient to form fine powder. The process may be conducted at relatively low temperatures, and in the case of many materials, at ambient or near ambient temperature and pressure conditions. The fine powder may be fluidized to aid in its discharge.
