Document Type and Number:
Japanese Patent JP3755224
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To continuously and effectively obtain uniformly shaped polymer pellets of high quality by a method wherein, after the pellets are scattered at an end of a vibrating screen by means of a distributor in the width direction of screen surface, and the pellets are separated by the vibrating screen, in which the ratio of length to width of a screen surface part having many holes is specified.
SOLUTION: Pellets, which are cut off and in which pellets of undesirable size are present, are scattered by a distributor 1 in the width direction of a screen. In a vibrating screen, a screen surface part 2 having many holes, in which the ratio of length to width L/W is 0.5-1.5, is provided. The vibrating screen is vibrated by a vibrating means 6 driven by a motor. Resin pellets having desirable size are caused to fall down from holes of the part 2 and discharged out of the screen from a product pellet outlet port 3. Resin pellets of undesirable size pass the part 2 and a screen surface part 5 having no hole and are discharged out of the screen from an unstandardized pellet outlet port 4.
