2) contain the component beneficial to plant growth and improvement soil in pelletizing additives raw material;
3) utilize the rounded grain mineral fertilizer of pelletizing additives production that can realize 100% water disintegration, and intensity can expire Sufficient market needs.
Specific implementation mode
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and it is described in detail It is as follows:
The pelletizing additives of the production rounded grain mineral fertilizer of low cost, each component mass percent are attapulgite 50- 73%, disintegrant 22-42%, amino acid 2-5%, magnesium sulfate 2-3%.Wherein, attapulgite can be some or all of by handing over Join amylose or bentonite substitutes.Disintegrant is the biological species waste of containing cellulose, hemicellulose, lignin;Main packet It includes:Sugar residue, residue of monosodium glutamate, furfural dregs etc..Amino acid includes mainly lysine, threonine, tryptophan etc..
The primary raw material of production rounded grain mineral fertilizer is epipastic mineral fertilizer, and epipastic mineral fertilizer is to use high temperature sintering Or calcium magnesium phosphate, siliceous fertilizer, calcium silicate fertilizer, silicon-calcium-potafertilizer fertilizer, silico-calcium potassic-magnesian fertilizer, potash-lime fertilizer, potassium silicon fertilizer and its derivative prepared by fusion method Product.
Embodiment 1 is to embodiment 6
The pelletizing additives of the production rounded grain mineral fertilizer of low cost, the pelletizing additives of embodiment 1 to embodiment 6 are each The additive amount of component proportion and pelletizing additives, granule strength and disintegration time, are shown in Table 1.
The additive amount of 1 pelletizing additives each group distribution ratio of table and pelletizing additives
Wherein, the disintegrant of embodiment 1,2,3 and 4 is corn sugar residue, and amino acid is lysine.
The attapulgite of embodiment 5 is replaced by amylose, and disintegrant is residue of monosodium glutamate, and amino acid is threonine.
The attapulgite of embodiment 6 is replaced by bentonite, and disintegrant is furfural dregs, and amino acid is tryptophan.
The pelletizing additives of the low cost of the present invention are used for rounded grain mineral fertilizer production method:By epipastic mineral fertilizer and After pelletizing additives are sufficiently mixed, pass through disc granulation, wet granular screening, particle drying, particle cooling, finished product screener successively Sequence obtains rounded grain mineral fertilizer.The mass ratio of epipastic mineral fertilizer and pelletizing additives is (85-92):(8-15).Wherein make It is (12-20) that the quality of water and mixed material mass ratio are sprayed into grain link:100.Drying is to particle moisture content≤3%, cooling 1mm-4.75mm rounded grain mineral fertilizer products, granule strength >=8N, disintegration time is made after machine is cooling, screening machine sieves< 20s。
The specific implementation process of the embodiment of the present invention:
(1) epipastic mineral fertilizer is prepared:Calcium magnesium phosphate, siliceous fertilizer, calcium silicate fertilizer, the silicon prepared using high temperature sintering or fusion method The mineral fertilizers such as calcium potash fertilizer, silico-calcium potassic-magnesian fertilizer, potash-lime fertilizer, potassium silicon fertilizer and its derived product, after high-temperature calcination, sintered product with Vitreum, melt, it is granular in addition it is big it is blocky exist, it is water cooled or air-cooled after grinding to certain fineness obtain epipastic mineral fertilizer.
(2) pelletizing additives of low cost are prepared:Attapulgite, disintegrant, amino acid, magnesium sulfate are pressed to the quality of table 1 Ratio weighs respectively, is uniformly mixed and obtains.
(3) raw material mixes:The pelletizing additives prepared and epipastic mineral fertilizer are claimed by the mass ratio of table 1 Amount is added in batch mixer and is uniformly mixed.
(4) raw material is granulated:Uniformly mixed material is added in granulating disc, during disk rotational, passes through spray The mass ratio of water of the head into material after penetrating atomization, water and material is (12-20):100, it can be timely according to the condition of production Adjustment.
(5) screening, drying, cooling of grain products and packaging:Grain products by grain size more than 1mm are at 180-240 DEG C Lower drying is less than 3%, after cooling in 25-35 minutes to moisture content, and screening obtains the rounded grain mineral fertilizer of 1mm-4.75mm, packs.
Main problem present in traditional round particulate mineral fertilizer preparation process has:(1) of high cost:Particulate mineral fertilizer per ton Material only pelletizing additives one are increased by cost about 150-200 members, or even more than 200 yuan;(2) intragranular disintegration is poor:It applies After soil, the long period is still in granular form, and cannot disperse, and influences absorption of the crop to nutritional ingredient;(3) granule strength compared with It is low, than more prominent the phenomenon that broken ball, picking in transport process.
From the results shown in Table 1, pelletizing additives using the present invention both can greatly reduce rounded grain mineral The production cost of fertilizer, and ensure the higher ratio of active ingredient holding in rounded grain mineral fertilizer, while granule strength >= 8N, disintegration time<20s, has well solved the above problem, and product accords with the demands of the market.
Present disclosure is not limited in the above embodiments, and the technical staff in same domain can be the present invention's Other embodiments can be proposed within technological guidance's thought easily, such as:It reduces raw material and mixes link, pelletizing additives are each Batch mixer is added according to corresponding proportion with epipastic mineral fertilizer and is uniformly mixed simultaneously for kind raw material;Or during pelletizing additives are formed One or more water-soluble dissolution of raw material to water in spray into pelletizing disks, and other raw materials are still mixed according to corresponding ratio It closes uniform, can obtain and above-described embodiment is similarly as a result, such embodiment is same domain technical staff in above-mentioned implementation It is readily apparent that on the basis of example, therefore such embodiment belongs to the scope of the present invention.
