SCREEN OF EXTRUSION GRANULATOR

摘要

PROBLEM TO BE SOLVED: To provide a screen of an extrusion granulator markedly increased in pressure-resistant strength and extended in its durable period to be reduced in its running cost to a large extent. SOLUTION: An outside escape hole (5) having a diameter larger than that of each of inside die holes (3) is allowed to concentrically communicate with each inside die hole (3) through a stepped part (4) and the thickness (T) of a die plate is set larger than the diameter (d1) of the inside die hole (3) and the depth (h1) of the inside die hole (3) is set almost equal to the diameter (d1) of the inside die hole (3) and the depth (h2) of the outside escape hole (5) is set to the surplus dimension of the thickness (T).
