Abstract

The invention relates to a granular fertilizer slow-release coloring device. The device comprises a quantitative feeder, a solution preparation device, a fluid flowmeter, a rotating drum and a finished product stock bin. The quantitative feeder is connected with a feeding port of the rotating drum, the solution preparation device is connected into the rotating drum through the fluid flowmeter, and a discharging port of the rotating drum is connected with the finished product stock bin. A fertilizer coloring agent comprises the components in parts by weight: 3-5 parts of a dye, 12-20 parts of a film forming agent, 1-3 parts of a dispersant, 130-160 parts of water, and 0-2 parts of an emulsifier. A fertilizer processed by the granular fertilizer slow-release coloring device has bright surface luster and regular particles, enables the release speed of quick-acting nutrients to be slowed down, and enables the granular fertilizer to be high-effectively prevented from caking.

Description

[0001] This application is a divisional application of the 201210339554.5 patent application. technical field [0002] The invention relates to a coloring agent for fertilizer and a method and device for sustained-release coloring of granular fertilizer, belonging to the technical field of fertilizer production. Background technique [0003] Agriculture is the basic industry of our country. To achieve the sustainable and stable development of agriculture, chemical fertilizers are indispensable. Therefore, the chemical fertilizer industry is listed as the first category "has a significant impact on the development of the national economy, and provides national basic industries, pillar industries and national defense construction. Guaranteed industry" is an important factor affecting the growth of grain production. my country feeds 23% of the world's population with 9% of the world's arable land, and has made a major contribution to the global eradication of hunger and poverty...
