Rotary Drum Granulator For Compound Fertilizer Making

Compound fertilizers have always been popular in the fertilizer market due to their large content and fast fertilizer effects. The fertilizer drum granulator is an important equipment for the production of compound fertilizer granules. Then how does rotary drum pellet making machine prepare compound fertilizer? You can find the answer from this post.

The working principle of drum granulator

Drum granulator in the pelleting process of compound fertilizer particles: the core is the small particles with a diameter of Ф1-2mm in the raw materials and returned materials, under the temperature and steam conditions of 60-65°C, with the help of the raw materials’ own viscosity and mechanical The interaction of forces will continue to roll and form soft particles of Ф2-5mm. When drying, with the evaporation of water, the particles will gradually solidify and form hard particles. This is the whole working process of rotary drum granulation.

How to improve pellet quality in rotary drum granulation

There are some tips for better rotary drum fertilizer granulation.

When granulating, the material should make an elliptical movement in the granulator or dryer. The material should occupy 1/6 of the cross-sectional area of the cylinder. Through the movement, the materials will rub against each other to produce stickiness, large absorption and small adhesion, and adhesion. into balls. The material should be smooth in motion, and should not be subjected to excessive impact or forced into a ball, otherwise the particle size will be uneven.

The way to improve the roundness of fertilizer pellets is to let the material roll and rub more before the particles are solidified. During the rolling, the surface of the particles is ground to remove the edges and corners, to fill in the gaps, and the more the roll is, the more round it is. Soft particles should not rise and fall vertically in the cylinder of drum pelletizer, otherwise it is easy to cause deformation of the particles and cause the particles to be out of round.

In the process of processing compound fertilizers, drum granulators should use low temperature and large air volume to minimize the temperature difference between the drying head and tail. Tail temperature is the focus of control, generally controlled at 45-65°C, urea dosage is 3-9%, tail temperature is controlled at about 65°C; urea dosage is 10-20%, tail temperature is controlled at about 60°C; urea dosage is 21 -38%, the tail temperature is controlled at about 55°C, to prevent the urea from being too high in temperature to melt and produce too much liquid phase, resulting in large particles or sludge. If ammonium chloride is used as the nitrogen source, the tail temperature can be controlled at about 65-80°C, and the drying tail temperature should be formulated and adjusted according to the output size and the actual situation of the equipment. The drying temperature is not fixed. It should be determined mainly by referring to the air volume of the system, the production formula and the drying conditions of the dried materials. The organic coordination of the moisture, temperature and drying temperature of the materials in the granulator is the key.

What Equipment Is Needed to Process Organic Fertilizer?

What equipment is needed to process organic fertilizer? Next, FPC will introduce the organic fertilizer equipment that needs to be used in conjunction with the production process of organic fertilizer.

  1. Fermentation of raw materials

The first step in the production of organic fertilizer is the fermentation of raw materials. There are three types of equipment used for raw material fermentation: manure fermentation tanks, self-propelled compost turners, and trough type compost turners. The purpose of using equipment is to save labor, speed up the fermentation of raw materials, make the fermentation of raw materials more uniform and thorough, and have reached the organic fertilizer content standard. The success or failure of organic fertilizer fermentation determines the quality of organic fertilizer, so the selection of fermentation equipment is very critical.

  1. Raw material crushing

In order to make the fermented organic fertilizer look even and fine, it is necessary to use a semi-wet material crusher to crush the raw materials. After crushing, high-quality powdered organic fertilizer can be obtained. The raw materials that are not thoroughly crushed need to be screened out by an organic fertilizer drum screening machine. Carry out secondary pulverization. If granular organic fertilizer is produced, the sieving step should be continued after the cooling process.

  1. Granulation

In order to be more convenient for transportation and storage, the powdered organic fertilizer needs to be granulated. The granulated organic fertilizer has high strength and density, which is more convenient for transportation and more convenient for later use. Generally, a new type of organic fertilizer stirring tooth granulator is used for granulation.

  1. Drying and cooling

The raw material during granulation still contains about 30% moisture, so the moisture in the granules should be removed in time after granulation to further improve the strength and prevent moldy or crushed during bagging and transportation. The granules need to enter immediately after being dried. The cooling system is convenient for further evaporation of water, and on the other hand, it is cooled and shaped. At this time, a rotary dryer and a cooler are needed.

  1. Particle screening

In the process of processing, there will be a small amount of oversized and oversized particles, which are screened out by the organic fertilizer drum screener. The oversized particles are returned to the granulator, and the oversized particles are returned to the pulverizer. Realize fully automated production.

How to Extend the Service Life of Organic Fertilizer Granulator?

The most commonly used and most important equipment in a complete organic fertilizer production line is the organic fertilizer granulator. As we all know, the equipment has its own service life, but some people can use the same equipment for many years, but some People can’t use it for a long time, mainly because everyone has different operating methods. More importantly, they don’t pay attention to the maintenance of equipment. So how should the organic fertilizer granulator be maintained?

  • The operator should pay attention to regularly check the components that are easily worn out in the structure, and observe whether the degree of wear is not serious or very serious. If it belongs to the latter, it should be replaced immediately to prevent accidents caused by persistent use.
  • As for the plane of the bottom frame where the movable device is placed, pay attention to maintaining sanitation and remove dust and other materials in time to prevent the movable bearing from moving smoothly on the bottom frame when the pelletizer equipment encounters unbreakable materials, which may cause serious accidents.

  • During the operation of the organic fertilizer granulation equipment, it is found that, like some newly installed wheel tyres, it is very easy to loosen, so it needs to be checked frequently. In addition, once the bearing oil temperature is found to rise too fast, or there is an abnormal impact sound from the rotating gear, the power should be cut off immediately, and the reason should be checked and then solved in detail.

  • Good lubricating oil is very helpful to bearing life. Therefore, the operator must ensure that the injected lubricating oil is clean and has good sealing performance.

As long as you can always adhere to the above four points, you can greatly increase the service life of your pelletizing equipment, and the performance of the equipment can always be stable and efficient.

What Is the Difference Between Dry Granulation and Wet Granulation?

We often receive calls from many customers to inquire about matters related to the organic fertilizer granulator, and it is difficult for many customers to distinguish what kind of granulation method they need. The difference of the granulation method is to choose the corresponding suitable granulation method according to the use requirements of the material. It is mainly divided into two categories: dry method and wet method:

Dry granulation

Mainly refers to products with relatively low moisture content. Generally, moisture content below 10% is a zero boundary value. (There are also very few materials that can reach 16%, such as some materials that only contain crystal water.) Dry granulation produces mostly irregular particles (such as common granular potash fertilizer) or, more generally speaking, like small gravel The sub-shapes are similar. With the current domestic industrial upgrading and environmental protection requirements becoming more and more stringent, many chemical and building materials powders need to be made into particles.

Wet granulation

There are also many equipment and methods in wet granulation for materials whose main indicator moisture is above 20%. Such as: plate granulation, roller granulation, screw granulation. The granulation methods used many years ago have been continued. After increasing the use environment and processing requirements of different materials, the continuous improvement has also made considerable progress. For example, the relatively popular organic fertilizer granulation in recent years, the particle size of these particles is between 1mm-6mm, and the above methods are used.

In the organic fertilizer granulator, dry granulation has lower energy consumption than wet granulation and is more environmentally friendly. It does not need to be dried, and does not add water and binder, so the material properties will not be changed. This is also the difference between dry granulation and wet granulation. Dry granulator machine is more suitable for industrialized mass production.

There is also a case that some materials require relatively small particle size, and products between tens of mesh and 100 mesh can also be reduced by airflow, spray, and flash drying.

Rubber Plate, an Ideal Lining Material for Drum Granulator

The main problem of traditional manual wet granulation is the serious loss of nitrogen caused by adding water, especially when the local nitrogen fertilizer varieties are mainly carbon and ammonia. In addition, it is also required to solve the problem of high efficiency mechanical granulation to promote the deep application of ball fertilizer in large area.

For a long time, many compound fertilizer manufacturers have been troubled by the high viscosity and corrosivity of materials, the adhesion and corrosion of cylinder in the production of fecal based compound fertilizer, ammonia acid compound fertilizer and monoammonium phosphate granulation. Therefore, in order to effectively prevent the material from sticking to the wall and caking, and to prevent the material from corroding the cylinder wall, we have been working hard to research new products.

After a lot of efforts and continuous testing, we have finally successfully trial produced the drum granulator. Furthermore, the efficiency and performance of the granulator in the production of different fertilizer granules were successfully tested, and the problem of nitrogen loss was basically solved. Compared with manual granulation, the efficiency of mechanical granulation is increased by 60 or 70 times, so as to promote the deep application of ball fertilizer in large capacity.

In order to prevent the compound fertilizer material from sticking and corroding the inner wall of the granulator, the rubber lining material must meet three requirements. Firstly, the rubber plate must be acid and alkali resistant to solve the corrosion problem; secondly, since the material generates chemical heat during the reaction process of the tubular reactor, when the material reaches the cylinder wall, the material temperature is still 100-150 ℃, so the rubber plate must have good heat resistance. The maximum heat resistance temperature of chloroprene rubber is 160 ℃, which meets the requirements; thirdly, the elasticity of rubber plate must be used to prevent the material from sticking, The structural design should be reasonable.
