Embodiment Construction

[0027] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0028] Such as figure 1 As shown, the preparation process of a novel high-tower granulated compound fertilizer involved in the present invention includes the steps of high-tower granulated compound fertilizer and the step of using zeolite powder for outer coating. In this way, the present invention can form a layer of zeolite powder on the periphery of the conventional high-tower granulated compound fertilizer due to the addition of the step of zeolite powder coating on the periphery, which can improve the slow-release effect of the compound fertilizer to a certain extent.

[0029] In addition, in the process of high-tower granulation compound fertilizer, it forms a mixed and molten state of urea, ammonium phosphate and potassium chloride in the mixing tank, and then extrudes the granules with several spaced ar...

Abstract

The invention discloses a preparation process of a novel tower granulation compound fertilizer. The preparation process comprises the steps of tower granulation of the compound fertilizer and zeolite powder periphery coating. The step of tower granulation of the compound fertilizer comprises the following steps: forming a mixed molten state of urea, ammonium phosphate and potassium chloride in a mixing tank, and then extrusively molding particles with a plurality of spaced arc-shaped grooves in granulation equipment, wherein the radiuses of the plurality of arc-shaped grooves are gradually increased and the arc-shaped grooves have the same circle center. The zeolite powder periphery coating refers to a step of adding a zeolite powder layer at the periphery of extrusion molding particles of granulation equipment by adopting a coating machine. Compared with the prior art, the long-acting slow-release performance of the compound fertilizer is improved from multiple angles, the absorption rate of the compound fertilizer by crops is greatly increased, and meanwhile, the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of compound fertilizer production, in particular to a preparation process of a novel high-tower granulated compound fertilizer. Background technique [0002] After the traditional nitrogen, phosphorus and potassium compound fertilizer is applied to the soil, it will quickly dissolve into the water due to factors such as rain erosion. Only a small part of the compound fertilizer dissolved in the water can be absorbed and utilized by crops, and most of it will be absorbed by the crops with the rainwater. It is lost to the river, which not only causes the problem of low fertilizer utilization rate, but also brings great pollution to the environment. [0003] In view of this, the applicant conducted in-depth research on the above-mentioned problems, and this case came into being. Contents of the invention [0004] The main purpose of the present invention is to provide a novel high-tower granulation compound fertilizer...
