Abstract
The invention discloses a preparation method of a novel granular potassium chloride fertilizer. The preparation method is characterized by comprising the following steps: adding a granular-making additive which accounts for 1%-20% of the total material amount into a raw material potassium chloride, uniformly mixing and putting the mixture into an agglomeration granulator, drying, cooling, and screening to obtain the novel epigranular pellet-shaped potassium chloride. The granular-making additive is powdery magnesium oxide. According to the invention, magnesium oxide is added into powdery potassium chloride. The powdery magnesium oxide plays a role in bonding and granulation and also plays a role in providing the nutrient element Mg required by crops. Diameter of the prepared novel granular potassium chloride fertilizer is 2-4 mm, and its granular strength is 40-60 N.
Description
Technical field
The present invention relates to a kind of manufacture method of novel particle Repone K fertilizer, particularly disclose a kind of method of utilizing powdery magnesium oxide to make novel particle Repone K fertilizer.
Background technology
Granulated fertilizer is compared with powdered fertilizer, and granulated fertilizer good physical performance, does not play dirt when handling, long-term storage is not lumpd, good fluidity, and the easy spreading that applies fertilizer, and can mechanical fertilization, also can play appropriate slow releasing function simultaneously, improve the utilization ratio of fertilizer.In addition, the close granulated fertilizer of size can be realized direct blending, obtains Bulk Blending Fertilizer cheaply.
Repone K is a kind of very important potash fertilizer kind, and the Repone K fertilizer on market is mainly the irregular Repone K of powdery and extruder grain gained.In view of the development trend of Bulk Blending Fertilizer, the demand of rounded grain Repone K is more vigorous.Because Repone K belongs to sand mold material, itself there is no viscosity and plasticity-, adopt ordinary method to be difficult to granulation, it is very difficult that prior art is produced rounded grain potash fertilizer, and there is shortcoming (the China Patent No. CN1769248 such as cost is high, nutrient content is low, granule strength is low, CN1356298, CN102765994, CN1530349).Method provided by the invention can guarantee that potash fertilizer has good outward appearance and granule strength, can provide again plant growth required magnesium elements, for peasant reduces costs, increases the benefit.
Summary of the invention
The invention provides a kind of manufacture method of utilizing powder magnesium oxide to produce novel particle Repone K fertilizer.This technological process is simple to operate, the even rounding of product appearance, the feature such as granule strength is high, nutrient is balanced.
The technical scheme of production granule potassium chloride proposed by the invention is:
A kind of manufacture method of novel particle Repone K fertilizer, it is characterized in that comprising the following steps: the granulating agent of the 1%-20% of the total amount that adds materials in raw material Repone K, mix the laggard granulating equipment that enters to reunite, drying, cooling, screening back obtain even-grained Grcular particles shape Repone K.
The granulating agent adding in described granulation process is powdery magnesium oxide.The magnesian fineness of powdery is 200-2000 order.
Raw material Repone K fineness <50 order.
Agglomeration granulation equipment in granulation process is rotary drum granulator or granulating disc.
The finished particle Repone K particle size range 2-4mm making.
The present invention, by adding granulating agent to improve the granulating performance of material, has improved the granule strength of finished product, thereby makes Repone K can adopt united pelleting process to carry out granulation, and considers the factor of cost and nutrient, and the present invention has advantages of following outstanding:
1, technological operation is simple.Adopt traditional Chemical Mixed Fertilizer manufacturing process, without extra increase equipment.
2, preparation cost is low.Powdery magnesium oxide both, as the material of bonding balling-up, improved again the required magnesium elements of plant-growth, had reduced the comprehensive cost of fertilizer.
3, granule strength is high.Production, storage, transportation and the use of fertilizer all require fertilizer to have certain granule strength, and the granule potassium chloride fertilizer average grain intensity that the present invention makes, between 40-60N, can reach requirement completely.
4, balling ratio is high.The present invention prepares rounded grain Repone K fertilizer yield rate and reaches more than 90%, has wide market outlook.
