2. The Rotary Drum Dryer

This is an indispensable and important equipment for the whole fertilizer manufacturing line. Besides, the dryer drum is equipped with the lifting plates, which can break up the large piece of materials. Therefore, it increases the contact area between materials and hot air, reduces the drying time and improves the working efficiency.

Furthermore, the entire fertilizer production line may includes fermentation system, crushing system, batching system, mixing system, granulation system, drying system, deodorizing or dedusting system, and packing system. We have different combination schemes for each customer according to the degree of automation and the scale of production.

How to Dispose Manure by The Drum Dryer?

The drying process is one of the main procedures in the fertilizer production line. Besides, it can effectively dry granular bio-fertilizer, organic fertilizer, and compound fertilizer. Also, the drying process have four steps to dispose materials.

The fertilizer drying technique also has a variety of options. So, we can combine with the characteristics of raw materials as well as the actual production needs, to provide fertilizer plants the suitable drying process for free.


The belt conveyor sends materials with high moisture into the cylinder of the drum dryer.

Drying by Hot Air

The rotary drum dryer creates heat energy through the heating source device which also sends hot air to the cylinder. Then, the material moisture continues to evaporate under the action of the high temperature.


When the hot air has removed the moisture, excess water escapes through an overflow drain, the pipe, or other relative devices.


After the drying treatment by the dryer, you can get fertilizers with less than 10% water content from the discharge port to realize the whole fertilizer drying process.

What Information You Should Know about Manure Drying Production Line for Sale?

There are some details below of each component in the manure drying production line. And, it contains the receiving of raw materials, pre-treatment, the drying equipment, heat-supply system, drying control, product packaging and waste gas treatment.

1. The Receiving of Raw Materials The Conveying Machine

The first step in the fertilizer drying production line is the receiving of raw materials. Thereby, it contains the guarantee of qualified raw materials, and adopting appropriate conveying ways to put them into the pre-treatment process. During this process, you should make a strict inspection of raw materials to fulfill the drying requirements. Simultaneously, in order to increase production efficiency, you can purchase automatic conveying equipment to accept and deliver raw materials.

We sincerely recommend our mobile belt conveyor to you! Firstly, our machine frame is composed of aluminum profile, stainless steel, or carbon steel, and the belt is made of rubber, PVC, PU, or other materials. Hence, our machine is durable and dependable, with a service life that is twice that of same products. In addition, it has the benefits of long conveying distance, big capacity, continuous conveying, and dependable operation, as well as the automatic control.

2. Pre-treatment of Raw Materials The Dewatering Machine

Pre-treatment is one of the key aspects of the drying production line, mainly including the removal of impurities and moisture. To begin, you ought to screen the raw materials primarily and decontaminated to remove big contaminants and stones. Then, you must lower materials’ moisture content to a certain range, for facilitating the subsequent drying process. Typically, this process employs mechanical or natural method for moisture removal.

However, natural dewatering means drying in the open air with smaller processing scale. Besides, this way is easily affected by the season and weather, and the dehydration time is longer. As a result, we suggest mechanical dewatering. There are two kinds of dewatering machines. Depending on your output, we propose the screw press dewatering equipment with an output of 10-20m³/h for small fertilizer plant customers. For higher output, why not try the inclined dewatering machine with a maximum capacity of 40m³ per hour?

3. The Drying Equipment

The rotary drum dryer is the core of the drying production line, and its principle or design parameters will have a direct impact on the drying effect and production costs. When you select a drying equipment, you must take into account all aspects of the actual manufacturing requirement.

We provide a large selection of drum dryers with outputs ranging from 1 to 18 tons per hour. Moreover, our dryers have the strong drying capacity, the smooth operation, and low energy consumption. It can dry a wide range of materials and we can customize according to your needs. Also, it is extensively used in the chemical, agricultural, mining, and other industries to dry wine lees, feed, straw, slag, sludge, coal, limestone, animal manure and other materials.

4. Heat-supply System

Heat source supply is the energy guarantee of drying production line. And its supply method and temperature control will affect the drying effect and production cost. Common heat-supply methods include natural gas, electricity and coal.

Among them, natural gas and electricity, as green, safe, and clean energy with great thermal efficiency, are particularly ideal for heat source choices. Nevertheless, their operational expenses are generally higher. Coal as a traditional heat source has the cheapest cost, but it generates more pollution and needs to be used with caution.

We have natural gas burner with dual purpose of oil and gas burning. Besides, it is mainly used for drying fertilizer or other materials. Another equipment is the hot blast furnace. It is lined with manganese steel plate, and the inner lining is firebrick, which is convenient to hoist and install. All in all, we can customize different types according to customer’s requirements.

5. Automatic Or Manual Drying Control

Drying control is one of the key links of drying production line, which mainly includes drying techniques and temperature control.

On one hand, our drying equipment mostly apply the cocurrent drying technique. They have wide materials adaptability, less energy consumption and convenient layout. Besides, it needs the dust collector to reduce the air pollution.

On the other hand, you can choose an automatic temperature control system to accomplish exact operation. Also, we advice to buy a cooling machine to make the temperature of fertilizer quickly down to a certain range, which is easier for subsequent packing and delivery.

Simultaneously, in order to assure production safety, we develop equipment for safety protection, such as an electric control box with centralized control of machine’s start and stop, regulation, and monitoring.

Here, when the temperature of the discharging gas is relatively low, the natural pumping capacity of the chimney on the dryer is insufficient. At this time, you’d better to apply our induced draft fan as the power of the dryer’s ventilation.

6. The Packaging Process Automatic Packing Scale

Packaging is the last step of the whole drying production line, which mainly includes packing, identification and inspection of the dry fertilizers.

  • First of all, it is necessary to choose suitable packaging materials and methods to meet the moisture-proof, rust-proof and pollution-proof requirements.
  • Besides, fertilizer packaging materials are always woven bags, and you can sell them in bulk, bags, barrels, etc.
  • Secondly, you should make quality inspection of the finished dry fertilizers to meets marketing standard.

For this, we have two optional application model for packing: single bucket packing scale or double bucket packing scale. There are full automation or semi-automation models according to your actual needs to choose.

  • The former machine completes the whole procedure of feeding, measuring, bagging, data printing, finished product outputting automatically.
  • In addition, the latter one requires manual assistance to complete the packaging process.

7. Waste Gas Treatment

Exhaust gas treatment is a crucial safeguard for the drying production line’s environmental protection, so you need to appropriately treat and manage the exhaust gas during the drying process.

  • First and foremost, you must investigate the source and composition of the exhaust gas in order to select the most suitable methods and facilities.
  • Moreover, common treatment methods include activated carbon adsorption, photocatalytic oxidation, catalytic combustion, etc.
  • And the installation of infrastructure has waste gas collecting systems, treatment equipment, and discharge pipelines.

We recommend activated carbon adsorption box, which is the purification equipment with low cost and good effect in dealing with organic waste gas and odor. Besides, its body is 304 stainless steel, carbon steel or high grade PP material, with high adsorption efficiency, wide application, easy maintenance, etc. Meanwhile, it can deal with a variety of mixing exhaust gas like CO2, SO2, CH4, etc.

The design of a fertilizer drying line project must take into account all elements. Through scientific and reasonable selection as well as strict operation management, it is possible to enhance the drying line’s production efficiency and product quality while minimizing energy consumption and environmental pollution, resulting in a win-win economic and social benefits.
