Rotary Drum Fertilizer Granulator for Sale

Let you know more about the rotary drum fertilizer granulator in fertilizer manufacturing

According to the report from our sales department, the rotary drum fertilizer granulator is one of the granulators that won the title of “the best sellers this year”. Then, what is a rotary drum granulator? Why could it outshine other machines on the market?

What Is a Rotary Drum Granulator?

The rotary drum granulator plays a crucial role in the process of fertilizer granulation. Considering its working principle—wet granulation—and large hourly capacity, our rotary pelletizer is favored by the owners of large-scale fertilizer production factories. As fertilizer manufacturers expand their production in order to scramble for a large share of the fertilizer market, they are eager to find a highly efficient granulator with a huge output to increase the productivity of their plants. However, what are the appealing and fascinating features of our rotary drum granulator that gain a strong favor with most fertilizer makers? Now, we will show you the answers in terms of the design and working process of our rotary drum fertilizer granulator.

 The Innovative Design of Our Rotary Drum Granulator

Are you thinking that it is just a normal one that shares a similarity with other rotary granulators on the markets after a hasty glance at our rotary drum fertilizer granulator, aren’t you? Yes, there is something in common.

Generally, our rotary drum fertilizer granulator consists of 2 riding gears and their bases, a supporting gear, a rotary drum, a rotor, a reducer, and belts. Sounds nothing special, right? However, we actually made some slight but vital changes and refinements to the design of our granular drum machine.

The manufacturing of rotary drum granulating machine

As a rotary granulator machine manufacturer in China, we have never stinted on the investment in innovation. We enrolled a batch of intellectuals to optimize the design of our rotary granulator. Because of the mutual efforts of these experts, there is a drastic improvement in the efficiency of our rotary drum granulator. Then, what is special about our machines?

Riding Gears and Their Bases

The riding gears of rotary drum granulator

Riding Gears

Our drum granulator has 2 riding gears that make the granulation drum rotate. Considering the huge friction, these gears are made of durable materials. So, they make it possible for rotary granulator to work for a long time in your plant.

The base of rotary drum granulator

The Base

The granulator has a large size and, thus, requires firm bases to support its gears and body. That is why the bases are made of carbon steel plate and U-steel, 2 kinds of durable and rigid steel with features of resisting high temperature.

The Rotary Drum Body

The lining of rotary drum granulating machine

Although the rotary drum body looks ordinary, a huge cylinder, there is something special and innovative inside it.

Our rotary drum has a special rubber lining, or a stainless steel lining if you want, that has the ability to resist the corrosion of acids. Accordingly, the inside wall of our rotary drum body is not likely to be corroded quickly during the production of fertilizer, particularly organic fertilizer.

The lining obviates the need for the scraper device, an indispensable part of most rotary granulators from other companies. Most importantly, it realizes the automation of cleaning mushy and sticky raw materials on the inner wall of our rotary drum granulator, improving the efficiency of machine maintenance.

The Cleaning Holes

Given our rotary granulator machine’s working principle—wet granulation, it is inevitable that wet raw materials can easily stick to the inner wall of our rotary granulation drum, adversely influencing the granulation rate. Though the lining can avoid a huge amount of fertilizer powder sticking to the machine, we designed several cleaning holes on the granulation drum to maximize the efficiency of cleaning.

During the production of fertilizer granules, there are hammers that knock these holes by gravity as the rotary drum rotates, shaking off the raw materials on the wall by vibration. As a result, you will not be barraged by problems, like a decline in granulation rate, a large waste of raw materials, and a nearly unaffordable cost and labor of machine maintenance.

How Does Our Rotary Drum Granulator Work?

Our rotary drum pelletizer works on the principle of wet granulation that is widely favored by large-scale fertilizer plant makers. Most importantly, our rotating granulator allows the mass production of cold and hot granulation, a powerful function that disc granulators lack. And that is another reason why fertilizer manufacturers choose our rotary pelletizer. Then, what exactly is our rotary granulator drum granulation process in fertilizer production?

Fine fertilizer powder crushed with a fertilizer grinder will be sent into the granulating machine by our auto conveying machine.

Our rotary drum pelletizer uses hot steam, or other chemical materials, such as phosphoric acid, to dampen your raw materials first and then cause chemical reactions and heat granulation. Alternatively, you can use water to wet your fertilizer powder if you like cool granulation.

As the rotary drum pelletizer rotates, your raw materials will stick together and form into small fertilizer granules. It is well known that rotary speed has an essential effect on granulation. Then, how fast does a granulation drum spin in the process of granulation?
Actually, the speed is contingent on the model of the rotary drum pelletizer. For example, the SXZGZ-1240, a drum pelletizer with an hour capacity of 3 tons, has a rotary speed of 17 r/min. Besides, the size of pellets made by drum pelletizer is about 3-4 mm.

Discharged fertilizer granules will flow to the rotary drum drying machine. Of course, the efficiency of drying is high if you use hot granulation because fertilizer powder with high temperature contains less water after being granulated.

3 Hot Types of Our Rotary Drum Granulator Last Year

The statistics for annual sales indicate, there are 3 top types of commercial rotary drum granulators, namely rotary drum sulphur granulators, drum granulation of NPK fertilizer, and large compost rotary drum granulator.

· Compound Fertilizer Rotary Drum Granulator ·

Influenced by the boom in compound fertilizer markets, fertilizer makers are eager to find an efficient granulator with large output to expand their production. But the reality is that most granulators can not satisfy their expectations in terms of daily capacity.

Now, we offer a compound fertilizer rotary drum granulator whose maximum hourly output reaches 20 tons per hour. Such a large rotary drum granulation machine enables the mass production of high-quality compound fertilizer products, making it possible for you to form a strong supply chain.

Find the Flat Ground

You should place our rotary drum fertilizer granulator on the flat concrete ground and fix it tightly with anchor bolts. Hence, our drum pelletizer is able to work stably for a longer time.

Adjust the Angle

Adjust the angle of our rotary granulator. The angle determines the time of granulation. The higher the angle of the rotary drum granulator is, the shorter the time of the granulating process is.

 Usually, the ideal range of the angle is between 2° and 5°. You can adjust the installation angle to meet your needs for fertilizer granules production.
