Press roller type organic fertilizer granulator

Abstract

The invention discloses a press roller type organic fertilizer granulator which comprises a feeding chamber, a pressing chamber, a forming chamber and a base which are sequentially arranged from top to bottom. A pressing roller assembly is arranged in the pressing chamber; a template is mounted at the lower part of the compression roller assembly in a matched manner; the template is provided witha material forming hole which is through up and down; a cut-off tool connected with the material forming hole is arranged in the forming chamber; a material poking disc is arranged at the lower part of the cut-off tool; and the template and the material poking disc are both sleeved outside the rotating shaft. The granulator can be used for granulation of organic fertilizer cylinders with differentspecifications, and is widely applied to granulation of base fertilizer after fermentation of animal waste and straw.

Description

technical field [0001] The invention relates to the field of organic fertilizer granulation, in particular to a roller-type organic fertilizer granulator. Background technique [0002] The organic fertilizer granulation equipment on the market mainly adopts a disc centrifugal granulator. The main principle is that various materials are added from the top of the equipment, pre-compressed by the spiral, and transported to the arc-shaped notch of the roller. The material bites into the groove and is forced to compress. After the material passes through the compression zone, the pressure it bears gradually decreases, and its surface tension and gravity make it come out naturally. The powdery under-sieve material is sent back to the raw material bin through the feeding device for secondary rolling. [0003] The main problems existing in the existing equipment: The organic fertilizer disc centrifugal granulator equipment is an open process and cannot be used for material pretreat...

AI Technical Summary

Problems solved by technology

[0003] The main problems existing in the existing equipment: The organic fertilizer disc centrifugal granulator equipment is an open process and cannot be used for material pretreatment, and the dust and smoke pollution is serious; the process conditions are high, the return is high, and the efficiency is low. For example: raw materials The size of the particle size affects the size of the molding, the amount of feeding affects the size of the molding, the feeding position is fixed, and the raw material moisture requirements are high; it cannot be molded at one time, and it needs to be crushed and granulated to meet the requirements; after molding, it needs to be dried to ensure the deformation rate. The forming rate is low, and the density of the particles is low, the production occupies a large space, the process is relatively cumbersome, requires more labor, and the processing cost is high
