AI Technical Summary

Technical Problem

The existing dry granulators tend to cause materials to bond into pieces and adhere to the pressure rollers under high humidity environments. During the dry pressing process, materials with high sugar content tend to melt and become soft due to heat accumulation during the dry pressing process, resulting in low production efficiency and waste of materials.

Method used

A dry granulator is designed to ensure dry and low temperature conditions of the material during dry pressure by inputting dehumidification and purifying compressed air into the granulation box to maintain the micro-environment humidity below 40%. The fine powder and new powder loading mechanism are recovered through the powder recovery storage mechanism to ensure drying and low temperature conditions of the material during the dry pressure process.

Benefits of technology

Effectively prevent materials from absorbing moisture and bonding into blocks, reduce fusibility problems caused by heat accumulation, improve dry pressure and granulation efficiency, avoid material waste, and reduce production costs.

Abstract

The invention discloses a dry granulator and a dry granulation method. The dry granulator comprises a feeding mechanism, a granulation box, an extrusion mechanism, a crushing mechanism, a granulation mechanism and a sorting mechanism; the feeding mechanism is connected to the granulation box for feeding materials into the granulation box, the extrusion mechanism, the crushing mechanism and the granulation mechanism are all located in the granulation box and are sequentially distributed along the material flow direction, the extrusion mechanism is used to extrude the material from the feeding mechanism to prepare a molding material, the crushing mechanism is used to crush the molding material from the extrusion mechanism to prepare a crushed material, the granulation mechanism is used to granulate the crushed material, the sorting mechanism is connected to the granulation mechanism for sorting particles and fine powder from the granulation mechanism, and the granulation box has a compressed air interface, which is used to input compressed air into the granulation box. The dry granulator has high dry pressing and granulation efficiency.
