Description
Technical field
The present invention relates to agricultural fertilizer field, particularly open a kind of low concentration Multi-functional circular granular potash fertilizer and preparation side
Method.
Background technology
Potassium chloride/potassium sulfate be agricultural use most common be also most important two kind potash fertilizer, potash fertilizer in the market
Predominantly powdery and extruder grain gained is irregular, and rounded grain potash fertilizer becomes scarce commodity.Compared with conventional composite fertilizer pelletize,
The pelletize difficulty of potash fertilizer mainly has following reason: 1. potassium chloride/potassium sulfate belongs to sand mold material, itself does not has viscosity and plastic
Property, use conventional method to be difficult to pelletize；2. potassium chloride/potassium sulfate dissolubility in water is relatively big, uses liquid needed for pellet granulation
Phasor is too big, so that the granular potash fertilizer intensity formed when pelletize is extremely low, it is impossible to realize large-scale production；The most too low wet strength
Making granular potash fertilizer badly broken when dry, yield rate is extremely low.
Additionally powdery potash fertilizer and the potash fertilizer of extruder grain gained on market, nutrient content is generally more than 50%, such
Powder potassium is difficult to mechanization on agricultural application, manually uses inconvenience, and the irregularly shaped potash fertilizer of extruder grain gained is also
Fail fundamentally to solve potash fertilizer transporting broken differentiation, be difficult to mechanization and use and be easily caused layering etc. for Bulk Blending Fertilizer
Many drawbacks.Meanwhile, this high concentration potash fertilizer is when using, and the quantity of goods produced used is the most less, so may result in fertilising
Inequality, fertilizer local concentration is too high, thus affects fertilizer efficiency, reduces utilization rate of fertilizer, and then decreases crop yield.
Calcium magnesium phosphate is conventional chemical fertilizer, and its chemical composition includes trace unit in available phosphorus, potassium, calcium, magnesium, silicon, ferrum, manganese etc.
Element, effective total nutrient content reaches more than 80%.Market price at 800-1200 yuan/ton, based on cost of material cheap.Simultaneously
It, as a kind of comprehensive alkaline fertilizer of nutrient, can improve soil physical and chemical property, alleviates soil compaction, acidifying, improves soil fertile
Power, it is used extensively to purify soil environment.But its commodity nature is powder, thus when using, dust can fly away everywhere,
Causing environmental pollution, fertilizer scatters and disappears and causes again waste, and adds the labor intensity used.
Summary of the invention
The problem that the object of the invention exists to overcome prior art, it is provided that a kind of low concentration Multi-functional circular granular potash fertilizer
And preparation method, this method utilizes physics and chemical method to produce low concentration Multi-functional circular granular potash fertilizer.This method operation, technique
Simply, it is easy to accomplish industrialized production, products obtained therefrom appearance uniform rounding, granule strength is high, nutrient equilibrium is comprehensive, comprehensive fertility
By force, peasant is facilitated again to use.It is provided that trace element in the phosphorus needed for plant growth, potassium, calcium, magnesium, silicon, ferrum, manganese etc. simultaneously, is
A kind of nutrition is complete, and function is many, and comprehensive fertility is strong, and yield potential is big, can improve soil physical and chemical property, alleviates soil compaction, acidifying,
Increase soil fertility, purify soil environment, the quick-acting Multifunctional potash fertilizer new varieties combined with slow.Potash fertilizer profit can be effectively improved
With the effect of rate, improve the comprehensive benefit of fertilizer.There are good market prospect and economic results in society.
The technical scheme is that
A kind of low concentration Multi-functional circular granular potash fertilizer and preparation method, it is characterised in that: with in potassium chloride, potassium sulfate powder
One or both as the basic material of potassium nutrition, mass percent is 30～90%；With calcium magnesium phosphate as inserts, quality
Percentage ratio is 10～70%；Activator accounts for the 0.1～1.5% of inserts quality；Basic material, inserts, activator are milled to
Regulation mesh number, mixing mixing is placed in Granulation Equipments, and in granulation process, sprinkling mixing Adlerika is as binding agent, and pelletize is straight
To fertile particle size growth to 2～5mm, screened, be dried to obtain the Multi-functional circular containing multiple middle trace element that particle diameter is 2～5mm
Granular potash fertilizer.
Described potassium chloride or potassium sulfate powder fineness are 20～100 mesh.
Described calcium magnesium phosphate fineness is 20～100 mesh.
Described activator is small molecular organic acid citric acid, citric acid waste, oxalic acid, tartaric acid, malic acid, succinic acid, second
One in acid, salicylic acid, lactic acid or two kinds and thing mixed above, fineness is 20～100 mesh.
The mixing Adlerika preparation process of described binding agent is: is dissolved in by magnesium sulfate in water, is heated to 40～65 DEG C,
And concentration is when being 2～4.6mol/L, adding and account for the carboxymethyl cellulose that aqueous solvent weight ratio is 0.1～2.0%, stirring solvent is equal
Even.
Described Granulation Equipments is granulating disc.
The present invention has an advantage highlighted below:
1, technological operation is simple.Use traditional Chemical Mixed Fertilizer manufacturing process, it is not necessary to additionally increase equipment.
2, production cost is low.Small molecular organic acid etc. used by implant calcium magnesium phosphate, activator all can use industrial goods, valency
Lattice are cheap, and binding agent usage amount is the most less simultaneously.
3, granule strength is high.This method produced rounded grain potash fertilizer can meet it and produce, stores, transports and use fertilizer
The requirement of grain intensity.
4, comprehensive nutrition function is many.The present invention prepares inserts and activator used by rounded grain potash fertilizer makes fertilizer can carry simultaneously
For trace element in the phosphorus needed for plant growth, potassium, calcium, magnesium, silicon, ferrum, manganese etc., being that a kind of nutrition is complete, function is many, comprehensive fertility
By force, yield potential is big, can improve soil physical and chemical property, link soil compaction, acidifying, increase soil fertility, and purifies soil environment,
There is wide market prospect and huge economic benefit and environmental benefit.
