Disc Granulator Structural Design

Pan Granulation Rate

Disc granulator is a new type of inclined plate pelletizing equipment, the granulation rate is more than 95%. The granulator of disc granulator has three discharge ports, which is convenient for intermittent production and greatly improves the labor efficiency. The production capacity can reach 24t / h. The reducer and motor are driven by flexible belt to make the starting stable and reduce the impact force. The bottom of the pelletizing pan is reinforced with a number of radiating steel plates, which are durable and non deformable. The thickened base design eliminates the need for anchor bolts. The main gear of granulator is quenched by high frequency, and its service life is doubled.

Performance 

Disc granulator has the advantages of uniform granulation, stable operation, high sphericity, high roundness, intuitive operation and convenient maintenance.

How does it work?

The raw powder is evenly wetted by the atomized water in the material mixer to form a spherical core with very uniform particle size, and then sent to the spherical disc for spherical formation. The moisture content of the ball should be controlled at 12-14%. Most of the water should be added to the twin shaft mixer. Only a small amount of make-up water is added to the ball plate, and the amount of water added is controlled at about 0 to 3%.

Finished products by pan granulation

The dry powder is directly added to the spherical plate and sprayed with appropriate amount of water. The core of raw material enters into the ball disc and is affected by centrifugal force, friction force and gravity, and moves along the parabola. Due to the adhesiveness and plasticity of materials, the cores adhere to each other and grow gradually in the process of movement. When the tilt angle, the height of the disc edge, the rotation speed and the humidity of the disc remain unchanged, the balls with different particle sizes will roll down from the edge of the disc at different exit angles due to different gravity. In the continuous rolling process, the ball constantly discharges water from the ball surface. Due to the cohesiveness of the material and the natural volatility of the liquid film on the surface, the ball has a certain strength, and then the swash plate body rotates. Both sides of the disc are discharged out of the carton. Detailed info, go here.

Pan Granulation Technology

As a fertilizer granulator which has been used for a long time in chemical fertilizer plant, pan granulator has its unique advantages. In the production of fertilizer granulation, the following factors exist in the particle uniformity.

Structure of pan pan granulator

The disc granulator adopts the whole arc structure, which effectively improves the granulation rate. Combined with non power scraper equipment, it can reduce the accumulation of materials in the granulation process and maximize the use of raw materials. In order to facilitate the flexibility and flexibility of field use, the base is firmly thickened and weighted, without the need for additional anchor screws to fix, which also helps to prevent chassis deformation. The disc granulator is very suitable for field operation, reduces the tedious installation and layout procedures, saves time and improves the work efficiency.

In the granulation stage of NPK fertilizer production line, with the continuous addition of raw materials, under the action of centrifugal force, the manufactured particles fall into the lower belt conveyor through the edge of the plate.

Pan fertilizer granulator

Elements of Pan fertilizer granulator

When the plate granulator processes raw materials, many parameters affect each other. For example, the smaller the diameter of the pelletizing disk is, the lower the disk height is, the larger the inclination angle of the disk is, and the higher the rotation speed is; if the disk height is increased, the inclination angle and rotation speed are higher. The smaller the tilt, the lower the speed.

As a NPK compound fertilizer production equipment, another factor affecting the disc granulator is the tilt angle of the disc. The angle of inclination should not be less than 35 ° during granulation, otherwise the material will stick to the disc and rotate with the disc body. With the increase of inclination angle and rotation speed, the material can avoid accumulating in the lower part without falling and rolling up and down.  More info on pan granulation process, go here with the link.

However, the larger the inclination angle is, the faster the downward rolling speed is, and the smaller the overflow particles are. The most suitable slant point of the disk is related to the diameter of the disk, that is, the slope of the disk decreases with the increase of the disk diameter. 

This is because the end velocity of particles moving along the disk surface increases as the disk diameter increases. In order to avoid the impact and fracture of other particles when the particles are down, the tilt of the disk must be reduced.

Recycling Animal Manure

Where Is It Possible To Work With A Fertilizer Dryer For Recycling Animal Manure?

Let's assume you are handling animal manure and would like to ensure the procedure is as straightforward as is possible. This isn't likely to mean you add up a production line and hope to find the best.

Instead, you will have to take one step back and select a fertilizer dryer. It is a must you should do things the correct way or you will be stuck in the tough spot that isn't easy to get out of.

This is a detailed look at where and when you can begin by using a fertilizer dryer for recycling animal manure.

Preparation for Long-Term Storage

Most animal manure is going to be stored for very long periods because it isn't gonna be used right away. This means you ought to prepare properly and make sure things are considered in your end. Otherwise, you are going to have low-grade animal manure that isn't going to be suitable for storing.

Most businesses may wish to set up your pet manure after it is through the production line, which suggests they will store it for too long periods.

If that is the situation, the fertilizer dryer should be excited to remove water content within the animal manure. This really is a must.

Consistent Processing

One of the greatest hurdles that come with an activity similar to this may be the processing. You are able to browse through the right organic materials and even make use of the best machinery however it is this step that will matter a whole lot. You have to make sure the fertilizer dryer is used right after the animal manure has become prepped.

This will cause consistent manure that is certainly in accordance with what you really are trying to get from the process. As time passes, this consistency is going to yield value.

Increase in Quality

The aim is to experience a fertilizer dryer good to go as soon as the production line has been doing its work. Generally, you will get the chance to believe things are okay and therefore means the manure could be processed "as they are" without having done anything. However, it is a major mistake for the reason that quality will depreciate immediately. You will end up having an asset that may be okay for a few days however begins to fall apart as a result of increased water content.

After it is time to set up a fertilizer dryer, it is very important comprehend the benefits that come with the equipment and why it is handy during the process. You don't want a production line being create that doesn't make up this as that is a major hurdle continuing to move forward. Your goal must be to keep things as elementary as possible and this means receiving the fertilizer dryer operational as soon as possible.

Once you accomplish this, the animal manure will be recycled correctly and definately will cause better results.
