30,000 Ton/Year Compound Fertilizer Production Line

Introduction

The whole set of production line, which is equipped with advanced and high-efficiency machines, can achieve 30,000 tons compound fertilizer production annually. According to the capacity, our compound fertilizer equipment is divide into 20,000 tons, 30,000 tons and 50,000 tons. Customers can choose whichever production line at will. The compound fertilizer production line is with lower investment and better economic returns. The complete equipment are distributed compactly, reasonably, and scientific. All machines, such as fertilizer mixer, fertilizer granulator, fertilizer coating machine etc. Run smoothly, with features of more energy-saving, lower maintenance cost, and easier operation.

Working Process of Medium Scale Compound Fertilizer Production Line

The technical process of compound fertilizer production line generally goes like this: materials proportioning, evenly mixing, granulating, drying, cooling, compound fertilizer coating, packaging.

1.Materials batching system: According to the market demand and local soil determination, according to a certain proportion of the allocation of urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, general calcium), potassium chloride (potassium sulphate) and other raw materials. Through the belt scale according to a certain proportion of additives, trace elements, etc. According to the formula ratio, all the raw materials are uniformly transported by the belt to the mixer. This process is called premix. It ensures accurate batching according to the formula and enables continuous high efficiency of batching.

2.Raw materials mixing: the selection of horizontal mixer which is an essential component in production, helps thoroughly mix raw materials again, high granules yield. We manufacture both single-shaft horizontal mixer and double-shaft mixer so that our clients can choose a more suitable one according to their productivity and preference.

3.Fertilizer granulating: the core part of compound fertilizer production line. Customers can choose disc granulator, rotary drum granulator, roller extrusion granulator or compound fertilizer granulator according to the actual demand. Here we choose rotary drum granulator. After mixing evenly, materials are transformed by the belt conveyor to the granulator to get into the uniformly sized particles.

4.Fertilizer drying and cooling process: Our high-output rotary drum drying machine is a drying equipment to reduce the moisture content of the end products. After drying, the moisture content of the compound fertilizer will be reduced from 20%-30% to 2%-5%. After drying, all materials need be sent into the cooler. The rotary drum cooling machine is connect with the rotary dryer with belt conveyor, to remove the dust and clean the exhaust together, which can improve the cooling efficiency and the rate of thermal energy utilization, reduce labor intensity, and further remove the moisture of the fertilizer.

5.Fertilizer screening: after cooling, there is still powdery materials in the end products. All fines and large size particles can be screened out using our rotary drum screening machine. Then fines being transported by belt conveyor are back to horizontal mixer for remixing and re-granulating with raw materials. While large particles need to be crushed in chain crusher before re-granulating. Quasi-finished products are conveyed into compound fertilizer coating machine. In this way, a complete production cycle is formed.

6.Compound Fertilizer Coating: the rotary drum coating machine manufactured by us is driven by main motor, belt, pulley and drive shaft. It is mainly used to coat a uniform layer of protective film in the surface of compound fertilizer, which effectively restrains the salt bridge and absorption of organic fertilizer, and make the particles more smooth. After coating, there is coming the final process of the whole production-packaging.

7.Fertilizer Packaging System: automatic quantitative packaging machine is adopted in this process. It consists of automatic weighing and packing machine, transport system, sealing machine. Feed bin also can be equipped according to customer’s demands. It can realize the quantitative package of the supplies in bulk, such as organic fertilizer and compound fertilizer, and has already widely used in the food processing factory, industrial production line, etc.
