Granulation molding process of secondary element water-soluble fertilizer

Abstract

The invention discloses a granulation forming process of a secondary element water-soluble fertilizer, which specifically comprises the following steps: S1, weighing raw materials: respectively weighing the raw materials in required parts by weight through batching equipment, and respectively storing the weighed components into a storage tank for later use, S2, carrying out homogenizing reaction,S3, carrying out mixing and preparing, S4, carrying out melting treatment, S5, carrying out crushing and grinding treatment, and S6, carrying out granulating and molding. The invention relates to thetechnical field of fertilizer processing. According to the granulation forming process of a secondary element water-soluble fertilizer, rapid granulation can be carried out by adopting a one-step heating, melting, granulating and forming method, the purpose of rapid and efficient granulation is well achieved, the granulation process is simple, a large amount of working time of production personneldoes not need to be spent in evaporating the water and fertilizer solution, the workload of the production personnel is greatly reduced, the production efficiency is improved, and thus the water andfertilizer production by people is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a granulation and molding process for water-soluble fertilizers with medium elements. Background technique [0002] Medium elements refer to the nutrient elements that are required in the growth process of crops, which are inferior to nitrogen, phosphorus, and potassium and higher than trace elements. Medium elements generally account for 0.1-1% of the dry weight of crops, and usually refer to calcium, magnesium, and sulfur. In the traditional classification of nutrient elements, calcium, magnesium, and sulfur are often classified as macronutrients, mainly because the absorption of these three elements by plants is also high, sometimes exceeding macronutrients, especially phosphorus. Absorption of calcium, magnesium, and sulfur in soil and accompanying ions of some fertilizers often contain a large amount of calcium, magnesium, and sulfur, so people often ignore the...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a granulation molding process for water-soluble fertilizer with medium amount of elements, which solves the problem that the existing granulation method is relatively cumbersome and needs to spend a lot of working time for the production personnel to evaporate the water and fertilizer solution Processing greatly increases the workload of production personnel, reduces production efficiency, and cannot achieve rapid granulation by adopting the method of one-time heating, melting, granulation and molding, and cannot achieve the purpose of rapid and efficient granulation.
