fertilizer granulator Nov 15, 2023

As a general organic fertilizer production, the steps mainly include crushing, fermentation, granulation, drying, and other steps. However, if you want to meet the local needs, you need to add a certain amount of N, P, K, and other composite fertilizers, then mix and stir evenly, and use physical extrusion to make particles.

The inorganic fertilizer composite fertilizer extrusion granulator is produced using a non drying room temperature process, with a production capacity of 1-1.5 tons/hour, 1.5-3 tons/hour, and other specifications. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). This equipment has low investment and good economic benefits. The complete equipment layout is compact, scientific and reasonable, energy-saving and consumption reducing, stable operation, reliable operation, and convenient maintenance.

The working principle of the inorganic fertilizer composite fertilizer extrusion granulator is that the belt pulley is driven by an electric motor, and the transmission belt is transmitted to a pair of high-pressure roller bodies with sliding mold shells through a reducer for relative work.

The two rollers of the inorganic fertilizer compound fertilizer extrusion granulator are interacted with each other by a set of opposing gears. The two rollers of the extrusion granulator are directly driven by two output shafts on a dedicated reducer to achieve the purpose of extrusion molding. During production, the raw materials enter the feed hopper and are relatively extruded by the high-pressure roller body. After demolding, they flow to the lower part of the roller body for crushing and forming.

The granulation methods of different types of organic fertilizer granulators

Organic fertilizer granulator machine is used to granulate various organic wastes (straw, livestock manure, cake fertilizer, peat, etc.) after fermentation, and process them into spherical, rod-shaped or other amorphous particles. Compared with traditional farmyard manure, pelletized organic manure not only promotes the reuse of organic waste materials, but also has the characteristics of high permeability and high fertilizer efficiency, so it is more and more widely used.
The existing granulators of organic fertilizer not only need to adjust the formula of fertilizer, but also adjust the temperature and humidity, especially the temperature and humidity conditions are very critical to the formation of organic fertilizer. However, the existing organic fertilizer granulator machine generally ignore the influence of temperature and humidity on the formation of granulation, resulting in the phenomenon of organic fertilizer sticking, caking or moistening, mildew before leaving the factory, low product quality and high fertilizer efficiency It needs to be improved. 

The output power of the organic fertilizer granulator machine is transmitted by the reducer through the transmission shaft, which drives the equipment to rotate as a whole. The front section is the forced feeding system, the back section is the internal stirring teeth, and the cylinder wall is lined with stainless steel. After the material enters, the stirring teeth force the material to form a ball. The ball forming rate is 100%, and the material moisture requirement is 25% – 45% It is not suitable to add too much humic acid, because humic acid will produce high temperature due to kneading, so that the material moisture is not balanced, which is easy to cause problems such as material not forming, equipment blocking and so on.

The Role of Binders in the Production of Fertilizer by Fertilizer Granulators

fertilizer granulator Nov 15, 2023

Binder refers to a substance that promotes the agglomeration of raw material powder and particles during the granulation process, improves the granulation efficiency, increases the yield, and improves the physical properties of the granules (strength, surface morphology, disintegration resistance, etc.). In wet granulation such as rotary drum granulator, disc granulator, and stirring granulator, granulating liquid such as water is added to the raw material powder to make the surface of the powder wet and form solid-liquid crosslinks. Reunite into pellets. On the other hand, in dry granulation, such as briquetting granulation and melt granulation, since the granulation is completed by intermolecular forces, there is no need to add a granulation binder.

The principle of drum granulation is that materials rely on surface tension, an appropriate amount of liquid phase, extrusion force generated by rolling between materials, and small particles are taken as the core in the correct movement direction of materials in the granulator to absorb large particles and adhere to small particles and form balls during rolling. The higher the rolling frequency in a certain time, the higher the balling rate and the rounder the particles are after forming.
The organic fertilizer rotary drum granulator used in small and medium-sized fertilizer plants is a rotating circular granulator with a diameter of 1.2 – 2.4m and a length of 3 – 6m. A material retaining ring is arranged at the feeding end and the middle part of the simplified body, and the tail is smooth. The middle retaining ring of the organic fertilizer drum granulator divides the simplified body into two areas, the front area is the mixing granulation area, and the rear area is the particle polishing area.

The granulation binder used in the fertilizer granulation process should have the following functions:a. Certain adhesion
b. High surface tension
c. High solid crosslinking strength after drying
d. Low cost
e. When mixed with chemical fertilizers, it is harmless to crops
f. Biodegradability of synthetic organic materials

How to configure equipment for organic fertilizer production lines in small aquaculture plants

fertilizer granulator Nov 10, 2023

How do small aquaculture plants configure organic fertilizer production lines? A series of organic fertilizer production lines mainly focus on the technology of decomposition, sterilization, and deodorization. They are large, medium, and small organic fertilizer equipment production lines that integrate practical and effective manure fermentation, particle processing, raw material mixing, drying, packaging, and other fertilizer production equipment processes. These processing processes are used to process livestock and poultry manure into harmless commercial organic fertilizers.

Powdered organic fertilizer refers to the fertilizer produced by fermenting organic raw materials in a certain proportion without causing particles. There is a certain difference from traditional composting fermentation, with the national standard of 40% organic matter, over 5% total nutrients, and 30% moisture. The equipment is also relatively simple, mainly consisting of the three stages of fermentation, namely pre mixing, flipping, refining, and packaging. The main purpose of fermentation is to decompose the macromolecular materials of organic raw materials into small molecule materials that can be absorbed and utilized by crops through microbial decomposition. The quality of fermentation is also related to the quality and effectiveness of organic fertilizers.

The main process of organic fertilizer production line equipment is to mix organic solid waste with a moisture content of less than 60%, auxiliary materials (such as plant straw), microbial fermentation agents, etc. evenly, and make them fully mature, sterilize, deodorize, and dehydrate through continuous aerobic fermentation in a pool. The moisture content of the decomposed material is generally within the range of 30-35%. After screening and magnetic separation, it can be directly used for pelletizing to produce round organic fertilizer, or further drying to produce powdered organic fertilizer.

The organic fertilizer produced by processing chicken manure, pig manure, cow manure, sludge, and straw is an organic matter long-term fertilizer, which can improve soil even if the fertilizer is effective for a long time. Vegetables and grains grown with organic fertilizers are pollution-free foods, which are vigorously promoted by the country and are also the healthy food that people are looking forward to today.
