<p>PURPOSE: A grinding device for waste plastics is provided to increase grinding efficiency and to prevent plastics from being softened by cooling high temperature heat generated from housing using cooling water. CONSTITUTION: A grinding device for waste plastics, which pulverizes waste plastics put through an opening of housing by blade rotation, comprises an upper frame in which an opening part in which pulverized materials are put is formed; a housing(11) in which the upper frame is detachably installed and which is composed of sub-frames in which outlets are formed; a pulverizing device which is rotatably installed in the housing and grinds the pulverized materials; an inlet(14) which is formed in one of rotary shafts(13) which rotate the housing and the blade(12) and flows the cooling water in and out; a cooling water circulation path in which cooling water is filled by being connected to the outlet; left and right rotary supporting members(17) which rotatably support a rotary shaft in which the grinder is installed; and pneumatic pressure feeding paths(18) which prevent pulverized materials from being flowed out through gaps from the inside of the housing.</p> |
