Abstract
The invention discloses a method for granulating fertilizer without drying. The method comprises the following steps: granulated fertilizer is obtained by inorganic, organic or compound powdery fertilizer through granulating and filtering; and 3 to 10 percent of magnesium oxide is added into the granulated fertilizer, so that the hardness of the granules can reach standard rate. The method selects the magnesium oxide (MgO) as a drying agent to be blended with wet granulated fertilizer, so that the magnesium oxide can sufficiently absorb mass moisture in the granulated fertilizer to ensure that the granulated fertilizer which is subjected to granulation reaches regulated hardness without drying equipment. The method for granulating the fertilizer without drying saves the drying equipment and drying process in granulating, filtering and drying processes for the fertilizer to save energy and shorten granulating time, thereby reducing production cost, and improving production efficiency. Meanwhile, magnesium ions are applied to soil along with the granulated fertilizer to play a role of trace fertilizer, thereby increasing nutrient content in soil, facilitating the nutrient balanced absorption of crops, and achieving the aims of improving crop quality and increasing yield.
Description
Technical field
The present invention relates to the technical field that a kind of granulation of fertilizer technical process exempts to dry.
Technical background
For utilization ratio and the merchandise sales that improve granulated fertilizer are worth, in traditional granulation of fertilizer is produced, finally become the granulated fertilizer finished product by technical process such as granulation, screening, oven dry.This production process, fixed capital drop into high, and the production time is long, and cost increases.The patent No.: 200410023736.7, a kind ofly exempt to dry the physics method and produce the compound fertilizer technology method, it is characterized in that following steps are arranged: on the basis of satisfying general composite fertilizer N, P, K content proportioning, allocate siccative 15% into.Production technique: sieve after utilizing tablets press granulation with secondary granulation function; During a granulation that the raw material and 10% siccative of general composite fertilizer N, P, K content is homogeneously mixing together; Add the siccative of residue 5% again in the secondary granulation district, this application siccative is selected for use: anhydrous magnesium sulfate, calcium sulphate hemihydrate and zeolite powder are formed.Too much sulfate ion can cause hardening of soil.And this application siccative need be distinguished twice adding, and operation is inconvenient.
Summary of the invention
The object of the present invention is to provide the oven dry-free method for granulation of fertilizer that a kind of technology is simple, cost is low, fertilizer efficiency is high.
Technical solution of the present invention is, provide a kind of oven dry-free method for granulation of fertilizer: inorganic, organic or compound class powdered fertilizer, through granulation, screen moistly particle fertilizer, in the particle fertilizer of humidity, add the magnesium oxide of the fertile weight 3-10% of particle, can remove stoving process from and become the particulate state finished product.
The present invention only selects a kind of raw material magnesium oxide (MgO) for use, less consumption, and that can finish inorganic fertilizer, fertilizer or compound fertilizer exempts to dry granulation, and method is simple, and raw materials cost is cheap.Magnesium oxide and moist granulated fertilizer blending as the abundant large quantity of moisture in the absorbing particles fertilizer of moisture adsorbent, make the particle fertilizer after the granulation can reach regulation hardness without drying plant, and particle fertilizer shape do not change.Oven dry-free method for granulation of fertilizer of the present invention in granulation of fertilizer, screening, stoving process flow process, is removed drying plant and baking operation from, save fixed capital input and a large amount of energy, disposable adding moisture adsorbent shortens the granulation time, thereby reduced production cost, enhanced productivity.And magnesium oxide not only plays the hygroscopic desiccation effect, and, can also increase the fertilizer efficiency in the soil because magnesium oxide be manured into soil with granulated fertilizer in after, magnesium ion is absorbed by crop as little fertilizer, can play and quicken the crop metabolism, help organic synthesizing, improve quality, increase output.
Embodiment
Inorganic, organic or compound class powdered fertilizer; by disc type or rotary drum granulator granulation; standard particle size is screened according to the rules then; the screening back adds the magnesium oxide (MgO) of the fertile weight percent 3-5% of particle; moisture content in the abundant absorbing particles fertilizer; promptly remove stoving process from, make fertile dry, the sclerosis of particle, reaching required standard hardness becomes finished product.
Preferably: with 1000 kilograms of granulation, the moist granulated fertilizers that filter out, be sprinkled into evenly that 50 kilograms in siccative (MgO) is puddled evenly, drying not, promptly get the fertile finished product of particle.
No matter the granulated fertilizer that oven dry-free method for granulation of the present invention is produced still under the storage requirement, all keeps former particle proterties and hardness in transportation.
Claims (1)
1, a kind of oven dry-free method for granulation of fertilizer is characterized in that: inorganic, organic or compound class powdered fertilizer, through granulation, screen moistly particle fertilizer, in the particle fertilizer of humidity, add the magnesium oxide that accounts for the fertile weight 3-10% of particle, and granulation gets final product.
