Compound Fertilizer Production Process
Compound Fertilizer Production Process

The compound fertilizer production line uses monomer basic fertilizers such as: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate monoammonium phosphate, diammonium phosphate, heavy calcium, general calcium), potassium chloride (potassium sulfate), etc. as raw materials. After being crushed to a certain degree of fineness, the material is agglomerated and granulated in the rolling bed of the drum granulator (or disc granulator) through humidification and heating.

During the granulation process, it can also be rotated if possible. The drum granulator adds a small amount of phosphoric acid and ammonia to improve the granulation conditions. The granulated materials are dried, sieved, and cooled to obtain NPK compound fertilizer products. This is also one of the methods widely used in the world. The early United States, India, Japan, Thailand and other Southeast Asian countries used this method for production.

This method has a wide range of sources of raw materials, simple processing, low investment, low production cost, quick start-up, large production flexibility, simple and easy adjustment of product grade, and strong versatility. The raw materials used are solid, and the raw materials are Reliability is not strong. Because it is the secondary processing of basic fertilizers, there is almost no environmental pollution problem. Since most of the current basic fertilizers are powdery, many small and medium-sized compound fertilizer plants mostly adopt this method.

What machines do you need to process compound fertilizer?

Introduction of the compound fertilizer production line

The compound fertilizer production line adopts the non-drying room temperature process production, one-time molding, the output is 1-2t/h, the compound fertilizer production line equipment investment is small, the effect is fast, and the economic benefit is good. The complete set of compound fertilizer equipment (click here to get) has a compact layout, scientific and reasonable flow, advanced technology, energy saving and consumption reduction, no three wastes, stable operation, reliable operation, convenient maintenance and wide raw material adaptability.

It is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical feed, coal, metallurgy, etc., and can produce compound fertilizer of various concentrations and various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) .

Compound fertilizer equipment characteristics: Compound fertilizer equipment is suitable for the direct production of crude fiber organic wastes with a moisture content of about 30%, such as fermented livestock and poultry manure, sugar factory filter sludge, urban sludge, paper sludge, distiller’s grains, straw, and peat. It can produce pure organic fertilizer, organic and inorganic fertilizer, and biological organic fertilizer of spherical particles.

The compound fertilizer equipment has a high ball formation rate and biological bacteria survival rate. The new technology can make the ball formation rate reach more than 90-95%. The new technology of low temperature and large air volume drying in the compound fertilizer production line can make the microbial bacteria survival rate reach more than 90%.

The compound fertilizer equipment has a short process flow and low operating cost. The organic raw materials used in the process do not require pretreatment such as drying and crushing. The process flow is short and the operating cost is low. (If traditional granulation processes such as discs or drums are used, post-fermentation Organic raw materials with a moisture content of about 30% are dried to below 13%, crushed to above 80 mesh, and the amount of organic materials added cannot be greater than 30%).
