  • The last one is limestone drum granulating equipment.

Limestone fertilizer is mainly used for balancing the ph of soil. As we all know, if the balance of soil ph is broken, the plant will not grow well, then leading to a bad yield. Recently years, people need limestone fertilizer more and more, only by improving the quality of fertilizer, can you get more profits than others. The limestone pellets made by our drum granulator have compact structure with high nutrient content and not easy to break. More importantly, our limestone drum granulator can meet your production capacity requirements while ensuring high quality.

2. How many models are there for different scales of fertilizer production?

In order to meet customers’ different demands, we designed 3 scales about drum granulator:

  • Small scale:

    For small scale compound fertilizer production line, there are two models of drum granulator could be your choices. The first is 1-3t/h. The power it costs is 5.5kw/h. The second one is 3-5t/h. And it costs 11kw/h. It’s obvious that this two model has matched capacity of small fertilizer making line and consume low energy.

  • Medium scale:

    As for medium scale, you can choose SXZGZ-1870 or SXZGZ-2080. Their capacity is between 5 and 15t/h. Their power is under 18.5kw/h. Compared with other companies, we always perfect our equipment to reduce the consumption and improve the capacity. Our medium scale drum granulator is more suitable for your choice than others.

  • Large scale:

    We have a large rotating drum granulator to meet your need about large-tonnage. Its length is 10m, and the diameter of the drum is 3.2m. The huge appearance strengthens its ability of granulating, its largest capacity can reach 30t/h. The high production capacity can save you a lot of time to manage other processes on the production line.

Model Power(kw) Diameter(mm) Length(mm) Installation Angle(°) Rotary Speed(r/min) Capacity(t/h)
SXZGZ-1240 5.5 1200 4000 2-5 17 1-3
SXZGZ-1560 11 1500 6000 2-5 17.5 3-5
SXZGZ-1870 15 1800 7000 2-5 11.5 5-8
SXZGZ-2080 18.5 2000 8000 2-5 11 8-15
SXZGZ-3210 37 3200 10000 2-5 9.5 15-30

How do we design a high quality rotary drum granulator?

The granular drum is made of threaded pipe in one time without too many small accessories. It can reduce lots of maintenance costs. The simple and practical structure with excellent corrosion and abrasion resistance and is not easy to be deformed and broken, so that the granulator can serve you for a long time.

high thickness and hardness steel used for our rotary drum granulator

Inside the drum, we use a special rubber lining or acid-proof stainless steel lining. Compared to the traditional scraper device used in other machinery company, our drum granulator can realize automatically remove scar on the inner wall of the drum. Efficiently reduce the paste and corrosion of drum inner wall by fertilizer. It also saves the labor needed to clean it up.
The other is our machine bracket. Because of the huge appearance of drum granulator, the bracket must be in very high hardness and durable. So we weld medium carbon steel plates and channels to ensure their high quality. And it has passed strict quality control and special process requirements. At last, all parts are combined together and formed the excellent granulator.

What are the advantages of ShunXin rotary granulating machine?

Because of the special simple structure, you don’t have to care much about small parts during use. The firm bracket helps the granulating drum run smoothly and steadily. The high quality of inner lining materials we adopt significantly prolong the service life of the drum granulating machine.

As mentioned above, we adopt advanced technology and reasonable design, the low power consumption and high economic benefit reduce the cost of production. Meanwhile, there is no Tri-wastes in the granulation process. That not only in line with today’s advocacy of green production, but also can take the pressure away of you to deal with waste.

How does this granulating machine make granules?

Our rotating drum granulator mainly consists of a motor, a belt pulley, reduction gears, big gear ring and a drum. When the granulator begins granulating, the main motor drives the belt pulley, which are driven to the driving shaft by the reduction gears, and works in opposite direction with the big gear ring. Then the raw fertilizer will be added into the drum from feed port. Through a certain amount of water or steam, the base fertilizer is fully reacted in chemical way after being wet in the drum body; then through the special structure inside the drum granulator, the raw material is made into pellets, and finally flows out through the outlet. The rate of granulating is about 70%.
To dispose the return materials, we have screening machine to screen them and return them into the rotary drum granulator again. The raw material are used efficiently.

How to maintain the rotating drum granulator when it’s not in use?

To make sure the granulator has stable efficiency and longer working life, the cleaning and maintenance is very important when it’s not in use. So how to maintain the machine correctly and economically? As an experienced equipment supplier, we will give you some helpful suggestions.

1. Cleaning the inner wall after granulating

If your fertilizer materials have high stickiness or corrosiveness, they are very easy to stick to or damage the inner wall. To help you clean the sticking fertilizer materials easily, we designed cleaning holes on the drum surface. You can use a hammer to knock the exposed lining wall through the holes. The fertilizer will fall off with the lining wall vibration. We can also equip the equipment with automatic hammers, that will save you lots of time and energy.

2. Daily maintenance of machine parts

The basis of maintaining fertilizer granulator is to make sure the working environment is clean and dry, without strong acid and corrosive substance. That will greatly reduce the damage from water, dust and corrosion. If the machine will not be used for a long time, you need to oil the important working parts (bearings, motor, gearing, etc) regularly to prevent rust.

3. Check the machine condition before use

Before using the granulator, it’s very necessary to check important parts of the machine. Only make sure that all parts are normal can the machine start to work. If there is something wrong before or during working, the operator needs to stop the granulator to find out the cause and maintain the machine timely.

Why the price of our rotary drum pelletizer is reasonable?

We have our own factory for producing fertilizer making machine, and we sell the equipment directly from factory. Without extra price, our drum granulator price is always more affordable. Otherwise, we have a professional team devotes to the improvement of machine’s quality, performance and working life. And we invest heavily in technological innovation, in case to reduce the cost of producing fertilizer for customers. Using our rotary drum granulator can save you a lot of costs and bring you better economical profits. So that, our drum granulating machine is reasonable and with high quality.
