The working principle and advantages of organic fertilizer rotary drying furnace:

fertilizer granulator Jun 7, 2024

Working principle: The organic fertilizer rotary drying furnace adopts patented technology and uses the principle of low-temperature hot air for drying. The equipment is equipped with a high-quality heating system and fan system inside, which sends hot air into the equipment through the heating system. Organic fertilizer is dried inside the equipment by rotating, and the fan system helps to circulate hot air, evenly heating the organic fertilizer, accelerating water evaporation, and ultimately achieving the drying effect.

Advantages: The organic fertilizer rotary drying furnace has the advantages of high efficiency, energy conservation, and uniform drying. Compared to traditional high-temperature drying methods, low-temperature hot air drying can retain the nutrients in organic fertilizers to a greater extent and improve product quality. At the same time, the equipment adopts a closed loop operation to reduce the loss of hot air and save energy. In addition, the rotary drying method allows organic fertilizers to be uniformly heated, avoiding the problem of incomplete drying of some organic fertilizers caused by uneven heating in traditional drying equipment.

It should be noted that organic waste such as cow and sheep manure may contain harmful substances such as heavy metals. Therefore, when producing organic fertilizers, it is necessary to pay attention to the safety and quality of raw materials, and conduct necessary testing and control. In addition, in order to improve the quality and efficiency of organic fertilizers, an appropriate amount of additives can be added, such as nutrients such as nitrogen, phosphorus, potassium, and bioactive substances.

The importance of residence time of fertilizer raw materials in granulation production equipment

fertilizer granulator Jun 7, 2024

The npk manufacturing process can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final product packaging. The complete set of equipment has less investment, quick effect and good economic benefits. The complete set of equipment has a compact process layout, is scientific and reasonable, saves energy and reduces consumption, and has stable and reliable operation.

In the fertilizer production process, a factor that is not well controlled will affect its organic fertilizer effect. In the field of continuous bulk solids processing equipment, residence time may be one of the most influential variables in process settings, especially in rotary dryers, rotary kilns , rotary drum granulator, or other types of drums when processing materials.

Residence time is the amount of time a material is processed in a given facility. In most process settings, a specific retention time must be able to be achieved to achieve its intended goal. For example, the need to achieve a specific moisture content, initiate or complete a chemical reaction or phase transition, form particles within a desired particle size distribution, etc.

For example, in terms of quality, a spin dryer without a proper understanding of the retention time can cause the material to reach the target moisture level prematurely in the drum, meaning the material will continue to dry for the remainder of the time. This can cause the material to overdry and break down into fine powder. Likewise, if the drum is not long enough to accommodate the necessary retention time, the material may exit the drum before reaching the desired moisture content, still not reaching the desired target particle size. In other cases, the quality may not be compromised, but the drum size may be too large, resulting in reduced efficiency. Therefore, in the production process of the npk fertilizer production line, it is necessary to control the time rhythm and pay more attention to the temperature, humidity, size and shape of the material.

How to measure the residence time of materials in a drum granulator?

fertilizer granulator Jun 4, 2024

The process flow of the complete set of npk fertilizer production line equipment can usually be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, and final product packaging.

Then how long does the material stay in the equipment (rotary drum granulator) to achieve the desired quality, the residence time is the amount of time the material is processed in a given equipment. In most npk manufacturing process setups, producers must be able to achieve specific retention times to achieve their desired goals.

While retention time looks simple in theory, it gets complicated when a continuous process is used. In a continuous production run, there are no batches, and there is no real boundary between “start” and “end”; material is constantly entering and exiting the drum at the same time, making it difficult to determine the true length of time to process a given portion of material.

1. Introduction to Tracers

Tracers such as dyes or chemicals are not always permitted due to product composition or contamination concerns. However, where permitted, the tracer can be a very useful tool for determining retention times; by measuring where the tracer begins to flow out of the drum and where the tracer is no longer seen, the average retention can be determined time.

2. Measure drum volume

The retention time can also be defined by measuring the volume of material in the drum or the weight of the material in the drum when the process is at steady state. In steady state, the material is fed and discharged at the same rate. The average retention time can be determined by dividing the material bed volume or material bed weight by the volumetric flow or mass flow. It is important to understand that retention times are always averaged across consecutive settings.

Process flow of fermentation and granulation production line for organic fertilizer

fertilizer granulator Jun 4, 2024

Organic fertilizer is a fertilizer made from organic waste such as animal manure, which is safe and environmentally friendly. It can not only increase crop yield but also improve soil quality. The supporting equipment for the production of organic fertilizer from livestock and poultry manure is as follows: fermentation tank, organic fertilizer flipping machine, crusher, screening machine, granulator, round throwing machine, packaging scale, and other organic fertilizer production lines.

Horizontal fermentation tank

Animal manure and auxiliary materials enter the fermentation tank and are quickly deodorized within 2-3 hours under the action of aerobic bacteria. By evenly supplying oxygen to the fermentation tank through the air supply and aeration system, the oxygen demand during the fermentation process is met, allowing the material to fully ferment and decompose. The high-temperature stage is maintained for 4-5 hours. The increase in temperature and ventilation and oxygenation accelerate the evaporation of moisture in materials. The waste gas and water vapor are treated and discharged through the deodorization system, thereby reducing the volume of materials and achieving the goal of reducing, stabilizing, and harmless treatment of materials.

Organic fertilizer hydraulic lifting and flipping machine

Mix livestock and poultry manure, straw, bacterial residue, fermentation strains, etc. to a moisture content of 60-65% and send them to the fermentation tank through an automatic distribution system. Then, the freely walking track type flipping machine on the fermentation tank will perform flipping, stirring, and material transfer work. Adopting a continuous production process, which requires regular flipping, feeding, and discharging every day to ensure continuous production and low production costs for fertilizers.

Organic fertilizer packaging and granulation equipment

The organic fertilizer processing workshop is equipped with a production, processing, and packaging line for powdered and granular (biological) organic fertilizers, including a forklift feeding hopper, crushing, screening, batching, mixing, granulation, drying, cooling, screening, coating, packaging, etc. It can flexibly add or reduce a certain process according to actual production needs.

Track flipping machine

The high-temperature aerobic fermentation treatment process is to mix organic waste and auxiliary materials (crushed sawdust, rice husks, corn stover, corn cob, peanut shells, etc.) in a certain proportion, and make fermentation strips with fermentation conditions. Under the action of aerobic fermentation bacteria, the organic matter continuously decomposes, producing a large amount of high temperature, promoting the evaporation of water in the materials, and killing pathogens, parasites, and weed seeds under high temperature conditions, achieving the goal of harmless treatment; The fermented materials can be used as raw materials for organic fertilizers and landscaping, achieving resource utilization.
