Problems solved by technology

The main problems of the above production forms are: drum granulation and high-tower granulation need to consume gas. With the restriction on the use of coal, many enterprises gradually transform their equipment and use biomass fuel or natural gas. These energy costs are quite high, resulting in The cost of the product increases; the mixed production of powder products has low technological content and cannot solve the interaction between products, which is prone to microbial activity being affected by salt damage; flaky extrusion granulation, with fewer particles, and The application method of granular fertilizer produced by drum and high tower granulation is the same, and it is difficult to improve labor productivity

Abstract

The invention relates to a fertilizer, in particular to a super-large-particle slow-release columnar fertilizer and a preparation method thereof. The preparation method of the fertilizer comprises the following step of carrying out extrusion molding on the raw materials; wherein the raw materials comprise 1.5 to 3.0 percent of magnesium stearate; and the pressure of the extrusion forming is 4000 to 6000 KN. By optimizing the raw material formula of the fertilizer (especially the raw materials comprise 1.5-3.0% of magnesium stearate) and assisting with a specific extrusion forming process, the super-large-particle slow-release columnar fertilizer can be prepared without adding any binder, and the fertilizer not only is easy to demould after extrusion forming, but also has relatively high biological activity and functionality, a full-element function is realized, and diversified requirements are met; moreover, the fertilizer is of an oversized granule type, nutrients of the fertilizer are concentrated and gathered and cannot be directly lost along with water, and the fertilizer has a slow release function, continuously meets the nutritional requirements of crops and meets the nutrient supply in the whole growth period.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a super-large granular slow-release columnar fertilizer and a preparation method thereof. Background technique [0002] At present, fertilizers are produced in various forms; among them, granular fertilizers generally adopt the form of drum granulation and tower granulation, and powder fertilizers are simply mixed and stirred raw materials. A few enterprises adopt extrusion granulation and have many equipments. For sheet extrusion equipment. The main problems of the above production forms are: drum granulation and high-tower granulation need to consume gas. With the restriction on the use of coal, many enterprises gradually transform their equipment and use biomass fuel or natural gas. These energy costs are quite high, resulting in The cost of the product increases; the mixed production of powder products has low technological content and cannot solve the interaction between products, which is p...
