概述   Description

        在固体与液体共存并以固体为主的分散体中，利用分散体的自粘性（或外加粘结性），通过强制方式（如挤压、重力、离心力、机械力、气流冲力等）使固体粉料基本微粒相互粘接、增大，并形成一定形状和粒度均匀、集中的颗粒群。 

        湿法造粒成套装置主要由混合（捏和）、造粒、干燥及其辅助系统设备构成。粉料经混合（捏和）后，进入造粒机形成所需粒度的含湿产品，经干燥得到颗粒状成品，从而实现造粒的目的。

        SET型双螺杆挤出造粒机分前出料式和侧出料式，前出料式造粒直径一般在 1.5~12mm之间选择，侧出料式造粒直径一般在0.7~2.0之间选择，颗粒形状为圆柱状，成粒率≥95%。

In the dispersed system of coexistent composition of solid power and liquid, besides with solid phase on the former, make use of the self cohesiveness of the dispersed system (or add binder) to make basic partials of solid powder bind each other and increase to form mass granule with uniform fair-size by means of exerting force) such as extruding force, gravity, centrifugal force, impulsive force, gravity, centrifugal force, mechanical force, impulsive force air flowed.Complete sets of equipment for wet granulation mainly consist of equipment for mixing,granulating,dry in and auxiliary system. Powder material being mixed is delivered into granulator sideband then to get end granular product through drying ,thus achieving the goal of granulation.

SET Type Double-Screw Granulator has two model of front and side for material to be extryded out. Dimeters of granular product granulated by front model may be normally selected between 1.5mm-12mm, and by side medel can be normally selected between 0.7mm-20mm. Granules are cylindrically shaped. The rate of end product is equal to or more than 95%.
