摘要： When a thermoplastic resin pellet is transported by air current, a floss is formed in pellet in a slight amount, which is flake-like or string-like and causes various troubles in the subsequent operations.A floss separator having a small size, a light weight and a superior floss-separation efficiency is provided.This separator consists mainly of a lower cylindrical column and an upper cylindrical chamber connected thereto, and further a specific inlet for introducing a mixture of air or nitrogen gas with a floss-containing pellet into the column and for imparting to the mixture, a helical ascending gas current, and baffles fixed onto the inner wall of the column at the upper end part thereof and counter-radially protruded therefrom, and having a specified angle of attack and a specified sweptback angle to the gas current line of the gas mixture, and also having a blow-through part formed by said baffles and the upper end part of the column. Pellet falls and separates at the baffles, while floss together with the gas pass therethrough.
