概述   Description

        在固體與液體共存并以固體為主的分散體中，利用分散體的自粘性（或外加粘結(jié)性），通過(guò)強(qiáng)制方式（如擠壓、重力、離心力、機(jī)械力、氣流沖力等）使固體粉料基本微粒相互粘接、增大，并形成一定形狀和粒度均勻、集中的顆粒群。 

        濕法造粒成套裝置主要由混合（捏和）、造粒、干燥及其輔助系統(tǒng)設(shè)備構(gòu)成。粉料經(jīng)混合（捏和）后，進(jìn)入造粒機(jī)形成所需粒度的含濕產(chǎn)品，經(jīng)干燥得到顆粒狀成品，從而實(shí)現(xiàn)造粒的目的。

        SET型雙螺桿擠出造粒機(jī)分前出料式和側(cè)出料式，前出料式造粒直徑一般在 1.5~12mm之間選擇，側(cè)出料式造粒直徑一般在0.7~2.0之間選擇，顆粒形狀為圓柱狀，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%.
