Self-grinding device of lump in rotary drum granulator

Abstract

The invention relates to a self-grinding device of a lump in a rotary drum granulator. The self-grinding device comprises a fragment screening mesh which is connected to a discharge end of the rotary drum granulator; the fragment screening mesh is completely coated on a port of the discharge end of the rotary drum granulator; and a plurality of fragment screening strips are coaxially, concentrically and evenly connected to the outer circumference of the granulator at intervals to form the fragment screening mesh, so as to achieve self-grinding of the lump of the granulator. The self-grinding device is simple in structure, low in production cost, low in artificial labor intensity, stable in production technology and high in rotate rate; a power source and equipment do not need to be added; the energy is saved and consumption is reduced; and the granulating output and the granulating quality are improved.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer and mixed fertilizer production, in particular to a self-crushing device for lumps in a drum granulator. Background technique [0002] In the production process of compound and mixed fertilizer granulation process, in addition to producing granules that meet the specifications, some clumps with high moisture content are also prone to be produced. In the subsequent drying process, the internal moisture is not easy to evaporate and remove, often causing Subsequent screening equipment is prone to paste screening and blockage of crushing equipment, which will cause system shutdown and affect work efficiency and product quality. If the drying temperature is increased, the energy consumption will be increased, and the roundness and surface smoothness of the qualified particles will be destroyed, which will not only reduce the appearance quality of the product, but also cause agglomeration of...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the impact of the lumps produced during the granulation of compound and mixed fertilizers on product quality, resulting in increased energy consumption, equipment blockage and damage, low efficiency, low yield, and poor product quality, the invention provides a simple structure, The self-crushing device in the drum granulator is easy to use, can effectively reduce the energy consumption of granulation, improve work efficiency, product yield, product quality, equipment service life and production safety performance
