Granulator

Abstract

The invention relates to the field of wet granulation, and provides a granulator, which is used for continuous granule decomposition, complete mixing and wet rolling granulation operation on wet materials. The granulator comprises a base, a granulation mechanism arranged on the base and a crushing and mixing mechanism arranged above the granulation mechanism, wherein the granulation mechanism comprises a charging barrel fixedly connected to the base, a turntable arranged in the charging barrel in a rotating manner, a tile-shaped stirring piece arranged on an upper cover of the charging barrel and used for stirring the materials to the rotating center of the turntable, and a turntable transmission device for driving the turntable to rotate, and a discharge port is also formed in a sidewall of the charging barrel; the crushing and mixing mechanism comprises a crushing and mixing box arranged below the upper cover of the charging barrel and positioned above the turntable, a rotating body arranged in the crushing and mixing box in the rotating manner and used for decomposing material granules and mixing the materials, a hopper communicated with the crushing and mixing box, and a rotating body transmission device for driving the rotating body to rotate.

Description

technical field [0001] The invention relates to the field of wet granulation, and provides a granulator, which is used for the continuous operation of granule decomposition, full mixing and wet rolling granulation of wet materials. Background technique [0002] Granulation technology has been widely used in medicine, food and other industries. As a branch of granulation technology, wet tumbling granulation plays an important role in the granulation operation requirements when fluid agents, binders and other additives need to be added to the matrix material. The structure of the wet rolling granulation equipment in the prior art is relatively complicated, and the size of the finished granules is not easy to adjust and control. When the wet rolling granulation process is adopted, there are corresponding requirements for the specific surface area of ​​the finished granules, so it is necessary to control the size of the material particles that are made into granules. It can sa...
