Embodiment 1

[0050] This production test was carried out in Shandong Linyi Zhongnong Sainty Ecological Fertilizer Co., Ltd. The production equipment is the production process of drum agglomeration method. The traditional granulation method uses urea-formaldehyde (liquid), monoammonium phosphate slurry and steam for granulation. The equipment and process index parameters are as follows:

[0051] Granulator length: 7.4m Granulator diameter: 2.2m

[0052] Drying kiln length: 28m Drying kiln diameter: 2.4m

[0053] Cooling cylinder length: 28m Cooling cylinder diameter: 2.2m

[0054] One mixer, one ton each time, intermittent feeding

[0055] Drying kiln head temperature: 180°C Drying kiln tail temperature: 55°C

[0056] Packing temperature after cooling: 40°C

[0057] Material temperature at the exit of the granulator: 55-60°C

[0058] The production formula is: 28-6-6 (potassium sulfate type)

[0059] Addition amount of granulation steam: 40kg / T, addition amount of urea-formaldehyde: 5...

Abstract

The invention relates to a granular composite fertilizer pelleting adhesive and a preparation method thereof. The pelleting adhesive consists of the following raw materials in percentage by mass: 0.1-5% of a thickening agent, 0.01-10% of a tackifier, 1-5% of a stabilizer and the balance of water. The pelleting adhesive preparation method comprises the following steps: putting a certain amount of water into a stirring tank, adding a certain percentage of the thickening agent and the stabilizer firstly, conducting stirring for about 30 minutes till complete dissolution, adding a certain percentage of the tackifier secondly, continuously conducting stirring for 30-45 minutes till the tackifier is completely dissolved, and putting the adhesive into a tank. When being used, the pelleting adhesive provided by the invention is capable of replacing vapor, spraying slurry, clay and the like used in the conventional pelleting process, is uniformly spayed to a material surface at the front end ofa pelleting roller, and is convenient to use, high in pelleting rate and capable of effectively reducing energy consumption and environment stress in the composite fertilizer production process.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer granulation, and in particular relates to a granulated compound fertilizer granulation binder and a preparation method thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] At present, the traditional compound fertilizer drum granulation uses clay, spray and steam to assist granulation. The addition of clay reduces the effective content of compound fertilizer, limits the diversification of compound fertilizer formula, and increases the production cost; the slurry needs to be heated, and it is inconvenient to use, and it is easy to block the pipeline; while the steam needs to be g...
