Abstract
The present invention relates to a kind ofly spray process for granulating with slip.This method is will contain N and K through heating
2The slip of O is sprayed onto in the granulating system by Liquid Level Pressure, with calcium magnesium phosphorus or with calcium magnesium phosphorus is that neutralizing agent is through pretreated general calcium, coarse whiting potash fertilizer and contain middle amount, the additive thing powder of trace element combines, contain N, P, K and Ca, the composite granulated fertilizer of multielements such as MgO, B, Zn through what moistening coalescent condensation granulation was just made.It is simple that this method has technology, and without binding agent, production process is continuous, productive rate height, characteristics such as epigranular.
Description
The invention relates to and a kind ofly will contain N, the slip of K is made the power binding agent and is adopted the spray granulating manufacturing to contain NPK and C
AO
2MGO, SIO
2, B, Z
NDeng applicable to various crops, the serial composite granulated fertilizer and the method thereof of various soil.
Method compound and granulated compound fertilizer has both at home and abroad at present: neutralisation (acid-base neutralisation granulation), mixing granulation method (adding wetting agent), extruder grain or the like, the shortcoming that these methods exist is need make neutralizing agent or binding agent with other flux, or need drying, pulverize pre-treatment etc., the production process more complicated, facility investment is big, and the construction period is long, or nutrient content instability, recently, disclosed two patent applications of Patent Office of the People's Republic of China, " Wrapped fertilizer and manufacturing process thereof " (CN85101008A); " anhydrous encapsulated fertilizer and manufacture method thereof " (CN87102116A).The former exists deficiency is will consume a certain amount of acid when system is joined nitrogen phosphorus mud, and the parcel drying is intermittently with long, complex process, adapt to for suitability for industrialized production is difficult, the deficiency that the latter exists is the energy expenditure height, the intensity of particle, uniformity coefficient are not really desirable, and the skin of parcel easily comes off.
Research the objective of the invention is to adopt a kind of novel method, makees binding agent without soda acid, can realize not having drying process again, continuous industry production, and energy consumption is low, and product granularity is even, the multi-functional compound particle of the multielement that intensity is high fertilizer.
The present invention has low-melting chemical property according to two kinds of anhydrous mixed salts, urea and vitriolate of tartar is added the water mixed preparing contain N, K
2The slip of O is heated 85～125O with steam
cFusion is often stirred and is kept constant temperature, with pressurization or mechanical means slip is delivered on the prilling granulator.
Calcium magnesium phosphorus is main basic raw material fertilizer of the present invention, and when using general calcium, when coarse whiting or potash fertilizer were done raw material, calcium magnesium phosphorus was again neutralizing agent and dry amendment.They constitute powder when entering granulating system, all water content should be controlled at 5～6%, below fineness 40 orders.At last slip is sprayed onto on the prilling granulator by spiral nozzle, combines with above-mentioned batch of material powder, through wetting, coalescent granulation, condensation just obtain epigranular, the granulated compound fertilizer that intensity is high.
With the produced compounded fertilizer of granulated of present method, contain NPK and moderate-element and trace element, so it can apply various soil, be suitable for the needs of various crops, and has a volume increase, improve the soil, long-actingly provide nutritive element of different nature, reach the nutrient requirement that applied once guarantees the crop whole growth phase to the crop different growing stages.
