Abstract

The invention belongs to the field of fertilizer industry, and relates to a production method of granulated calcium ammonium nitrate. The method comprises the steps that: dilute nitric acid and calcium carbonate are subjected to a neutralization reaction; a calcium nitrate solution is subjected to pres-filtration; the calcium nitrate liquid is mixed with an ammonium nitrate liquid; press-filtration, concentration, granulation, packaging, and inspecting are carried out; and the obtained granulated calcium ammonium nitrate is stored. The method provided by the invention has the advantages of novel design, unique method, low production cost, easy operation, and high practicality. The method can be popularized.

Description

technical field [0001] The invention relates to a production method of granulated calcium ammonium nitrate, belonging to the fertilizer industry. Background technique [0002] At present, there is a disadvantage of insoluble ammonium nitrate and calcium in the fertilizer industrial production. However, the simultaneous application of two kinds of fertilizers has the problems of large consumption and high input. Contents of the invention [0003] The invention provides a method for producing granulated calcium ammonium nitrate, which can overcome the above drawbacks. [0004] The present invention is realized by adopting the following technical scheme: a production method of granulated calcium ammonium nitrate, which comprises dilute nitric acid, calcium carbonate neutralization reaction, calcium nitrate solution pressure filtration, calcium nitrate liquid, ammonium nitrate liquid mixing, pressure filtration , concentration, granulation, packaging, inspection and storage,...
