Continuous granulator and granulating method by gravity method

Abstract

The present invention relates to a gravity method continuous granulation equipment and granulation method. The granulation equipment comprises a dust collection device, a granulation chamber, a liquid spray system, a drying chamber, a hot air system, a continuous feeding device, a discharger and a ventilation plate ; It is characterized in that: it also includes a throat, a classification device for distinguishing qualified and unqualified particles, and a return device for returning unqualified particles; a throat and a ventilation plate are arranged between the granulation chamber and the drying chamber, and the throat, ventilation The plates are respectively connected with the hot air system; the lower part of the drying chamber is equipped with a grading device; the outlet of the grading device is respectively connected with the discharger and the return device. In this equipment, the powdery materials are directly and continuously completed the production of granulation, drying, classification, and discharge of qualified particles. It can produce various particles, high efficiency, energy saving, and adjustable particle size.

Description

technical field [0001] The invention relates to a granulation equipment and a granulation method using the granulation equipment, in particular to a granulation equipment and a granulation method for continuous production of agglomerated spherical granular materials by using a gravity method, and belongs to the field of spray granulation equipment. Background technique [0002] Granular materials have the advantages of fluidity, good air permeability, no dust pollution, easy storage, easy dissolution, and not easy to deteriorate, so the application fields of granular products are very wide, such as food malted milk, coffee, milk powder, soybean milk and various granulation of various catalysts, additives, dyes and pigments in chemical industry, granulation of various granules in medicine, granulation before tableting, granulation of various ceramic products in building materials, etc., especially At present, the new methods of ceramic tile production all adopt the process of...
