Abstract
The invention discloses 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.Described granulating agent is powdered magnesia.The present invention by adding magnesium oxide in powdery Repone K, and powdered magnesia had both played the effect of bonded pelleting, served again the effect providing crop desired nutritional element M g.Obtained novel particle Repone K fertilizer diameter is 2-4mm, granule strength 40-60N.
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 utilizing powdered magnesia 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 during handling, long-term storage is not lumpd, good fluidity, and apply fertilizer easy spreading, and can mechanical fertilization, also can play appropriate slow releasing function simultaneously, improves the utilization ratio of fertilizer.In addition, the granulated fertilizer that size is close can realize direct blending, obtains the Bulk Blending Fertilizer of low cost.
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-, ordinary method is adopted to be difficult to granulation, it is very difficult that prior art produces 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 ensure that potash fertilizer has good outward appearance and granule strength, can provide again the magnesium elements needed for plant growth, for peasant reduces costs, increases the benefit.
Summary of the invention
The invention provides a kind of manufacture method 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 features 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 added in described granulation process is powdered magnesia.The fineness of powdered magnesia is 200-2000 order.
Raw material Repone K fineness <50 order.
Agglomeration granulation equipment in granulation process is rotary drum granulator or granulating disc.
Obtained finished particle Repone K particle size range 2-4mm.
The present invention improves the granulating performance of material by adding granulating agent, improve the granule strength of finished product, thus makes Repone K that united pelleting process can be adopted to carry out granulation, and considers the factor of cost and nutrient, and the present invention has following outstanding advantage:
1, technological operation is simple.Adopt traditional Chemical Mixed Fertilizer manufacturing process, without the need to additionally increasing equipment.
2, preparation cost is low.Powdered magnesia, both as the material of bonding balling-up, improves again the magnesium elements needed for plant-growth, reduces the comprehensive cost of fertilizer.
3, granule strength is high.The production of fertilizer, storage, transport and use and all require that fertilizer has certain granule strength, the granule potassium chloride fertilizer average grain intensity that the present invention obtains, 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.
