Granulation equipment capable of controlling particle size

Abstract

The invention discloses granulation equipment capable of controlling the particle size, and relates to the technical field of granulation equipment. The granulation equipment comprises a feed inlet, four nozzles capable of adjusting the inlet and outlet of an adhesive are arranged below the feed inlet, the adhesive enters an extrusion bin, a spiral extrusion rod is arranged in the extrusion bin, and through the work of the extrusion bin, raw materials entering from the feed inlet can be treated into clusters; a mold with controllable particle size is arranged in the middle, and agglomerated particles are pressed into molds with different pore diameters by adjusting a cover above the mold; and finally, a collecting bin is arranged, drying equipment is arranged in the collecting bin, and the particles are collected in the collecting bin after being dried. According to the invention, the particle size of particles can be controlled in a mode of not replacing the mold, the adjusting mode is simple and convenient, the practicability is relatively high, and the granulation work can be better and faster completed.

Description

technical field [0001] The invention relates to the technical field of granulation equipment, in particular to equipment capable of controlling particle size. Background technique [0002] In the field of soil heavy metal remediation, passivators such as fly ash and biomass ash need to be added to the soil, but they cannot be directly added to the soil, so they need to be made into particles and added to the soil. Most of the current granulation methods are divided into three categories: wet granulation, dry granulation and spray granulation, among which wet granulation is the most widely used. Wet granulation is to add a binder to the powder, through the binder bridge or The bonding effect makes the powder gather together to prepare granules. The surface of the granules produced by the wet method is round and has the advantages of good granule quality, beautiful appearance, strong wear resistance, and good compression molding. [0003] In the existing wet granulator, throu...

Problems solved by technology

In the production process of ring die pellets, according to the different types of granulation, the requirements are different. In order to obtain pellets with different diameters, it is necessary to replace the ring die and other components. However, the installation and disassembly process of the ring die is complicated, requires many accessories, and is time-consuming. Laborious, there are certain safety hazards, and it is difficult to meet the production needs; the existing technology obviously has inconvenience and defects in actual use, so it is necessary to improve the ring die structure to improve efficiency
