Abstract
The invention provides a special corn nitro-sulfur-based compound fertilizer and a preparation method thereof, and relates to the technical field of fertilizer preparation. The corn nitro-sulfur-based compound fertilizer is prepared from the following raw materials in parts by weight: 10-12 parts of nitramine, 12-14 parts of ammonium dihydric phosphate, 11-13 parts of potash fertilizer, 2-4 parts of cupric sulfate and 3-5 parts of instant boron. The special corn nitro-sulfur-based compound fertilizer has the benefits that the technological process is concise, the raw material ratio is reasonable, the maintenance operation and the production management are facilitated, long-time and continuous stable operation can be realized, more strong and healthy growth of the corn can be ensured, the yield can be higher, and the quality is better.
Description
Technical field
The present invention relates to fertilizer production technology field, be specifically related to special nitrate-based compound fertilizer of a kind of corn and preparation method thereof.
Background technology
Compound manure be by chemical process or (with) blending means make containing any two or three chemical fertilizer in crop alimentary elemental nitrogen, phosphorus, potassium.Its effect is to meet the composite demand of the multiple nutrient of agricultural demand under different working conditions and balance.In a large number for modern agriculture.Due to agriculture needs, compound manure particularly high-concentration compound fertilizer material is the inexorable trend of fertilizer variety development.The early stage chemical fertilizer industry of majority state is taking productive unit fertilizer as main.The U.S. is early stage in 20th century, just taking calcium superphosphate as basis, is mixed together (granulation sometimes) uses with Peruvian guano, sodium nitrate, sylvite and some organic waste.This moment, the N of 40%～50% in the chemical fertilizer aggregate consumption such as the U.S., West Europe and Japan, 80%～85% P2O5 and 85%～90% K2O provide with the form of compound manure.Along with the development of soil fertilizer science and agricultural fertilizer technology, agricultural has been moved towards to apply fertilizers scientifically.Apply fertilizers scientifically and must determine fertilising kind and quantity according to factors such as different soil types and character, fertility level, crop species and weather condition, so just can avoid excessive using or shortage one or more nutritive elements and cause waste in soil, but because composite fertilizer's nutrient content of using is in the market difficult to control, environmental-protecting performance is poor, also must use the composite fertilizer of different proportionings to apply fertilizer according to the difference of crop, when very few, do not have effect, too much time, can cause farm crop death.The trouble operating extremely.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of reasonable ratio, the manufacture craft of the reliable novel nitrate-based compound fertilizer of production safety.
Technical problem to be solved by this invention realizes by the following technical solutions:
The special nitrate-based compound fertilizer of a kind of corn, comprises that the raw material of following proportioning forms:
The preferred umber of each raw material is:
Another object of the present invention is to provide a kind of method of preparing the special nitrate-based compound fertilizer of corn of the present invention,
By taking as follows each raw material:
(1), above raw material is carried out after proportioning, be uniformly mixed formation mixture.
(2), the mixture in step 1 is thrown in into pulverizer and pulverized.
(3), the mixture after pulverizing in step 2 is conveyed into tablets press, add steam, through propylhomoserin tubular reactor, reacting the granulation time is 3-5 minute.
(4), the mixture of granulating and forming is dropped into dryer, tentatively dry 20-30 minute.
(5), preliminary mixture of drying in step 4 is carried out to secondary drying 20-30 minute again.
(6), a mixed thing of secondary drying in step 6 is promoted to vibration sieve by bucket elevator, carry out particle screen selecting.
(7), by step 7 screening after granular mixture carry out heat sieve, temperature is at 80-90 DEG C.
(8), the finished particle by screen cloth in step 7 entered to cooling drum carry out tentatively coolingly, the time is controlled at 15-25 minute.
(9), that preliminary cooling granular mixture is carried out to secondary is cooling, the time is controlled at 15-25 minute.
(10), the granular mixture in step 9 is carried out to cold screening, temperature is controlled at 30-40 DEG C.
(11), the granular mixture after cold screening is carried out to film, then metering packing, inspection, obtains finished product.
The invention has the beneficial effects as follows: technical process of the present invention is succinct, reasonable raw material proportioning, maintenance operation and production management facility, can realize long-time continuous stable operation, ensured that corn crop growing way is more strong, and output is higher, and quality is better.
