Abstract
The invention provides a fondant slip tower type granulation composite fertilizer and method for preparation which comprises, using high temperature molten urea as carrying agent, mixing the raw material evenly, granulation through tower top drench cooling, high temperature melting one material and loading into mixer with a pump, squashing another part of the raw material, mixing homogeneously and loading into mixer, conveying the two path raw material to tower top through transfer pump, spraying, natural air cooling into balls. The composite fertilizer according to the invention comprises urea 45-50 parts, potassium chloride 20-25 parts and phosphoric ammonium 25-30 parts.
Description
Technical field
The present invention relates to a kind of melt slime granulating composite fertilizer and manufacture method thereof.
Background technology
At present, be used for all kinds of composite fertilizers (mixing fertile) of farm crop, the several of main problems of existence is that fertilizer is deposited easy caking, and a material is not slick and sly, and is inhomogeneous, and nutrient proportioning instability, is unfavorable for the balanced fertilising in farmland.
Simultaneously since the composite fertilizer that traditional prilling process is produced (mixing fertile) since its granulation process belong to simple physics sticking and, structure is more open, the fertilizer dissolving discharges very fast, fertilizer efficiency is decomposed and is run off soon, utilization rate of fertilizer is lower.Dry screening process after traditional granulation, energy consumption consumption is big.
Summary of the invention
The objective of the invention is to improve the shortcoming of prior art and a kind of melt slime granulating composite fertilizer and manufacture method thereof are provided, for achieving the above object, the present invention takes following design:
Manufacturing processed adopts high-temperature fusion urea to do carrier, raw material is merged evenly, again through cat head spray cooling granulating.
Step 1: through high-temperature fusion (130 ℃-145 ℃), through broken uniform mixing post-heating, broken granularity is less than or equal to 20 orders with another part raw material with a kind of raw material;
Step 2: above-mentioned a kind of raw material is measured through electronic measuring scale,, above-mentioned another part raw material is sent into mixing tank with screw machine, mix with being pumped into mixing tank;
The preparation process of step 1 and step 2 is not introduced the bonding granulation of moisture in system;
Step 3: the two-way raw material is delivered to cat head through transferpump, and spray falls then, and material is made in natural ventilation cooling balling-up.
The composition of melt slime granulating composite fertilizer of the present invention: (weight proportion)
Urea 45-50 part
Repone K 20-25 part
Phosphorus ammonium 25-30 part
Tower height is at 60～100 meters, and tower diameter is at 8～18 meters.Preparation process is not introduced the bonding granulation of moisture in system, can prevent to lump because of Moisture high UCL.
Advantage of the present invention is: the compound manure of the present invention's preparation is on the microcosmic molecular level, with raw materials such as urea, Repone K, phosphorus ammonium, potassiumphosphates, be fused into an organic nutrient integral body,, form isostatic and stablize the nutrient unit by various interactions of going up between the nutrient, like this, can continuously discharge nutrient according to absorbing state in each vegetative period of farm crop, be made for thing and absorb Different Nutrients, thereby reduce the decomposition loss of fertilizer in the farmland, improve chemical fertilizer utilization ratio.
The melting method composite fertilizer of the present invention's preparation, the characteristics of a maximum adopt high-temperature melting method exactly in preparation process, raw material is merged together, its process has been avoided introducing moisture and has been dissolved in system, thereby prevented, thereby the trouble of having avoided storage and having used because of Moisture high UCL makes fertilizer agglomeration.Dry screening process after having saved traditional granulation simultaneously, thereby save energy consumption.
The solution method composite fertilizer of the present invention's preparation, what adopt in preparation process is high tower spray naturally cooling, a granulating forming technique, there is not returning charge in this technology, and throughput is greatly improved, and has avoided because of the low big defect of returning charge amount of traditional method granulating rate, save the energy, improve plant factor.Because of almost there not being the returning charge dust pollution, Working environment is more cleaned simultaneously, avoided three waste discharge.
