Abstract
The invention relates to a fertilizer, particularly to a compound fertilizer and a preparation method thereof, which are mainly used for the soil nutrition of crops and belong to the technical field of fertilizer production. The compound fertilizer is prepared by using urea, monoammonium phosphate and potassium chloride as main raw materials and adopting the steps of adding a small quantity of one or the combination of trace elements: boron, zinc, manganese and molybdenum; pulverizing the raw materials; granulating; drying and the like. The compound fertilizer has high concentration, large fertilizer effect, uniform quality, uniform fertilizer effect, dispersity and non-agglomeration by granulation and convenient mechanical or manual fertilization, and contains abundant nutritious components without harming the crops.
Description
Technical field
The present invention relates to a kind of fertilizer, be specifically related to a kind of composite fertilizer and preparation method thereof, be mainly used in the soil nutrient of farm crop, belong to the chemical fertilizers production technical field.
Background technology
The production of farm crop process certain period is until maturation, can output than the fruit of thousand times of its original seed tuples, must absorb a large amount of nutrition from soil, wherein needing maximum is nitrogen, phosphorus, potassium, because the content of this three major types element in soil far can not satisfy the growth needs of plant, accomplish increasing both production and income, what need suit according to the situation of soil element replenishes, and in a kind of chemical fertilizer, the chemical fertilizer of simple substance that only contains a kind of nutritive ingredient, contain nitrogen simultaneously, phosphorus, the chemical fertilizer of two or more nutritive ingredients such as potassium is a composite fertilizer, and composite fertilizer's prescription commonly used is single, can not satisfy the nutritional needs of soil.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of composite fertilizer and preparation method thereof is provided, this composite fertilizer is a main raw material with urea, monoammonium phosphate, Repone K mainly, add a small amount of trace element, wherein a kind of or its combination of boron, zinc, manganese, iron, molybdenum makes through raw material pulverizing, granulation, drying and other steps.This composite fertilizer's concentration height, fertilizer efficiency are big, and composite fertilizer is even matter, contains rich nutrient contents, and fertilizer efficiency is even, can not injure farm crop, and through granulation, fertilizer is scattered, does not lump, and mechanical fertilization or manual fertilising be all very convenient.
The present invention realizes with following technical scheme: a kind of composite fertilizer, it is characterized in that: this composite fertilizer is a main raw material with urea, monoammonium phosphate, Repone K mainly, add a small amount of trace element, wherein a kind of or its combination of boron, zinc, manganese, iron, molybdenum makes through raw material pulverizing, granulation, drying and other steps.
The preparation method of the described composite fertilizer of a kind of claim 1, carry out as follows:
(1) raw material pulverizing: select chain hammer type or drum-type pulverizer for use, desired raw material is crushed to below the granularity 1mm, stand-by;
(2) weighing mixes: the raw material of step (1) is added to carry in mixing machine behind the trace element mix, through the vibratory screening apparatus screening, return greater than the material of 1mm again and to pulverize;
(3) granulation: with the material that mixing machine mixes, be conveyed in the tablets press, add an amount of tackiness agent and carry out granulation;
(4) drying: higher moisture is contained in the composite fertilizer after the granulation, input drying machine inner drying;
(5) screening, packing: dried granular complex fertilizer is transported to double deck screen and sieves, to obtain the suitable finished product of globule size, the packing warehouse-in.
Advantage of the present invention is: this composite fertilizer's concentration height, fertilizer efficiency are big, and composite fertilizer is even matter, contains rich nutrient contents, and fertilizer efficiency is even, can not injure farm crop, and through granulation, fertilizer is scattered, does not lump, and mechanical fertilization or manual fertilising be all very convenient.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
Embodiment,
A kind of composite fertilizer, this composite fertilizer are main raw material with urea, monoammonium phosphate, Repone K mainly, add a small amount of trace element, and wherein a kind of or its combination of boron, zinc, manganese, iron, molybdenum makes through raw material pulverizing, granulation, drying and other steps.
The preparation method of the described composite fertilizer of a kind of claim 1, carry out as follows:
(1) raw material pulverizing: select chain hammer type or drum-type pulverizer for use, desired raw material is crushed to below the granularity 1mm, stand-by;
(2) weighing mixes: the raw material of step (1) is added to carry in mixing machine behind the trace element mix, through the vibratory screening apparatus screening, return greater than the material of 1mm again and to pulverize;
(3) granulation: with the material that mixing machine mixes, be conveyed in the tablets press, add an amount of tackiness agent and carry out granulation;
(4) drying: higher moisture is contained in the composite fertilizer after the granulation, input drying machine inner drying;
