Abstract

The invention belongs to the technical field of compound fertilizer granulating agents, and provides a compound fertilizer granulating agent. The compound fertilizer granulating agent is prepared from, by weight, 25-38 parts of molasses, 5-15 parts of lignosulfonate, 8-20 parts of polyoxyethylene ether, 16-23 parts of starch, 8-17 parts of modified attapulgite and 25-38 parts of water. The compound fertilizer granulating agent is high in adhesiveness and low in use level, and made fertilizer is high in granule strength.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer granulation, and in particular relates to a compound fertilizer granulation agent. Background technique [0002] The vast majority of solid compound fertilizers produced in countries around the world and China are granular fertilizers. Granular fertilizers have the following advantages in terms of physical properties: ① Small specific surface area, reducing the possibility of agglomeration. ②It has good fluidity, which is convenient for mechanized loading and unloading and fertilization. ③ The bulk density is small, which relatively reduces the cost of packaging, storage or transportation. ④ The dissolution rate of granular fertilizer in the soil is slow, which can reduce or eliminate the damage to the roots of crops, and also reduce the leaching loss of nitrogen nutrients. [0003] For compound fertilizers, binders must be added if they want to form round grains. The most commonly ...
