Embodiment Construction

[0025] The following structural drawings and embodiments further illustrate the present invention.

[0026] A kind of air-cooled crystallization granulation method of full melting compound fertilizer, it specifically comprises the following steps:

[0027] In the first step, the compound fertilizer slurry in the fully molten state is sprayed from the rotary granulation head located at the top of the prilling tower with a tower height of 15-50 meters and a tower diameter of 6-12 meters;

[0028] The second step is to install the first group of cooling fans blowing into the tower around the prilling tower body at a position of less than 4 meters (including 4 meters) from the prilling head, so that the air outlet direction of each fan is in line with the horizontal plane. The included angle is 0-75 degrees, the best is 15-60 degrees, and the direction between the diameter and the diameter is 0-75 degrees (the best is 5-45 degrees) to deliver cooling air to the tower, and the air ...

Abstract

The invention discloses an air-cooled crystal prilling method of all-weld composite fertilizer and device, which comprises the following steps: making the wind of fan blow into tower into vorticity through layout position and angle of fan rationally; making particles of slip initiate descending motion; extending decent and cooling time; augmenting contact face with cold-blast air; making high-heat particles falling into crystallization temperature swiftly; getting good granulated exterior.

Description

technical field [0001] The present invention relates to a compound fertilizer granulation forming method and its device, in particular to an air-cooled crystallization granulation method and equipment for a full-melt compound fertilizer, specifically an air-cooled crystallization granulation for a full-melt compound fertilizer Method and device thereof. Background technique [0002] In recent years, the production process of producing full-melt compound fertilizer (ie NPK compound fertilizer) in my country has been greatly improved. The process has a series of problems such as low efficiency, poor appearance of the finished product, and high energy consumption. For this reason, people have invented a new tower granulation process. The products produced by this process have a round appearance, accurate and uniform nutrients, and high fertilizer utilization. Popular. However, the main problem of this process is that in order to increase the cooling effect, the tower body is mo...
