Problems solved by technology
Simply powdering or coating the anti-caking agent on the surface of compound fertilizer granules can no longer meet the needs of compound fertilizer anti-caking, and it is necessary to add granulation aids from the granulation process of compound fertilizer to improve the physical properties of compound fertilizer granules

Embodiment 1
[0019] Each component is calculated by weight, put 60 parts of 500 mesh attapulgite, 25 parts of 200 mesh powder, and 15 parts of naphthalenesulfonate formaldehyde condensate into a double-helix conical mixer to fully stir and mix evenly. It can be made into a high-tower compound fertilizer granulation improver.
Embodiment 2
[0021] Each component is calculated by weight, 40 parts of 600-mesh attapulgite, 15 parts of 300-mesh drawing powder, and 10 parts of naphthalenesulfonate formaldehyde condensate are put into a double-helix conical mixer to fully stir and mix evenly. It can be made into a high-tower compound fertilizer granulation improver.
Embodiment 3
[0023] Each component is calculated by weight, put 50 parts of 550 mesh attapulgite, 20 parts of 250 mesh powder, and 5 parts of naphthalenesulfonate formaldehyde condensate into a double-helix conical mixer to fully stir and mix evenly. It can be made into a high-tower compound fertilizer granulation improver.

Abstract
The invention relates to a granulation modifier for a high-tower compound fertilizer and application thereof. The granulation modifier consists of the following components in part by mass: 40 to 60 parts of attapulgite, 15 to 25 parts of nekal and 5 to 15 parts of naphthalene sulfonic acid formaldehyde condensation product. A product is powder or particles. When added in the granulation process of the high-tower compound fertilizer according to a certain ratio, the granulation modifier can effectively improve the granulation of the compound fertilizer, the intensity of compound fertilizer particles and the surface smoothness of the compound fertilizer particles, and reduce the water content of the compound fertilizer particles and compound fertilizer dust, and the like.
Description
technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a high-tower compound fertilizer granulation improver and application thereof. Background technique [0002] There are a few conditioners that are added to the material before compound fertilizer granulation as hardeners or crystal modifiers, which can improve the granulation of compound fertilizers. The "internal" conditioner of ammonium nitrate is used to inhibit the crystal phase phase caused by temperature changes. Particle breakage caused by the change. Before urea granulation, 0.2%-0.5% formaldehyde or urea-formaldehyde part is added to the melt as hardener and anti-caking agent. Compound fertilizers made with wet-process phosphoric acid contain iron-aluminophosphate impurities that are effective "internal" anti-caking agents. Iron aluminum phosphate is a colloidal substance that can harden compound fertilizers and hinder liquid phase flow. The dosage of diatomite, ka...
