Abstract
The process of producing potassium ammonium magnesium phosphate fertilizer for planting includes mixing magnesium oxide, ammonium dihydrogen phosphate and potassium dihydrogen phosphate in certain weight proportion in some mixer, crushing the mixture in some crusher, pelletizing in some pelletizer, sieving and drying. The process has the advantages of less steps, simplicity, short production period, low production cost, high output and controllable slow release of magnesium in the fertilizer.
Description
Technical field
The present invention relates to a kind of preparation method of ammonium magnesium phosphate potash fertilizer that uses in the production of planting.
Background technology
Multi-form agriculture is produced the instant type chemical fertilizer that use more, utilization rate of fertilizer is low, and do not have a function of improving melon and fruit, vegetables, flowers self quality, can not satisfy people is keeping on the former feature base melon and fruit, vegetables, flowers, have better color characteristics or have more ornamental demand, life-time service also can make soil compaction, worsens the quality of soil, polluted source.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of preparation method of ammonium magnesium phosphate potash fertilizer that uses in the production of planting is provided.
Technical scheme of the present invention is: a kind of preparation method of ammonium magnesium phosphate potash fertilizer that uses in the production of planting; it is characterized in that: composition is formed: magnesium oxide 15-22%; primary ammonium phosphate 50-60%; potassium primary phosphate 18-20%; after three kinds of raw material compositions are pressed proportion ingredient in the composition composition; put into mixing device, behind the thorough mixing, put into shredding unit; be crushed to the 60-200 order; raw material after pulverizing is placed on the granulating disc, after 5 ℃-30 ℃ water atomization, is sprayed on the raw material after the pulverizing; start granulating disc in the time of water spray; with the running of the raw material behind water spray granulation, after master batch occurring, row spraying again; after treating that the feed particles surface water is state of saturation; granulating disc is row running granulation again, after the attached powder in feed particles surface is abundant, and row spraying again; and so forth; to the needs particle diameter, after sieving, the particulate state fertilizer that will meet the particle diameter requirement is dried to moisture content under 65 ℃ of-120 ℃ of temperature be to get final product below 5% until granulation.
The present invention has the following advantages: operation is few, and method is easy, and the cycle is short, lowers production cost, improves output, can also pass through the slow degree of the content decision fertilizer of adjustment magnesium.
Embodiment
Embodiment: a kind of preparation method of ammonium magnesium phosphate potash fertilizer that uses in the production of planting; with magnesium oxide 15-22%; primary ammonium phosphate 50-60%; after three kinds of raw material compositions of potassium primary phosphate 18-20% are pressed proportion ingredient; after putting into the mixing device thorough mixing; put into shredding unit; be crushed to the 60-200 order; raw material after pulverizing is placed on the granulating disc, after 5 ℃-30 ℃ water atomization, is sprayed on the raw material after the pulverizing; start granulating disc in the time of water spray; with the running of the raw material behind water spray granulation, after master batch occurring, row spraying again; after treating that the feed particles surface water is state of saturation; granulating disc is row running granulation again, after the attached powder in feed particles surface is abundant, and row spraying again; and so forth; to the needs particle diameter, after sieving, the particulate state fertilizer that will meet the particle diameter requirement is dried to moisture content under 65 ℃ of-120 ℃ of temperature be to get final product below 5% until granulation.
