Double Roller Granulator
The double roller granulator is an essential equipment for compound fertilizer granulation. This type of machine adopts the principle of physical extrusion, and turns the powder materials into pellets that shape you want. Because it adopts dry granulation, fertilizer granulation can cut the drying procedure. You can package the formed low moisture fertilizer pellets directly. Therefore, it’s a replacement product for saving energy and lowering cost in the complex fertilizer granulation business.
Here is more information about our double roller extrusion granulation machine for your reference.
How does extrusion granulator adopt dry granulation method?
Fertilizer roller compactor is a special granulator. Different from other fertilizer pellet making machine, it uses dry granulation technology for making powder into granules. And the wet granulation equipment requires high moisture content materials. Then it is applicable for you to add binders or some liquid into materials during the granulation. While, this machine can accept the materials whose moisture content is between 5%-10%. Meanwhile, there are two rotating rollers, which will extrude your dry powder material into shaped granules.
This machine is often used for making complex fertilizer. It is applicable for you to use some powdery materials, which is not suitable for mixing with liquid for pelletizing. Especially, if you use this extrusion granulation equipment for granulating, you do not need to buy a dryer and cooler. Because the pellets made by this granulator have low moisture content. You can pack them directly for selling. While, if you want your fertilizer pellets have higher quality, it is helpful for you to equip with a screening machine and coating machine before packing.
What is the main part of double roller pelletizer?
In general, a roller extrusion granulator includes 4 main parts. They are rack section, driving part, extrusion granulating part, crushing and separating part. Now Shunxin experts will give you a detailed information as follows.
Designs for Double Roller Extrusion Granulation in Our Factory
The double roller extrusion granulator making machine structure mainly has granulation, molding and screening parts. And we are going to know more about how they design and work subsequently.
Our factory makes special designs for double rollers.
How to extrude pellets by the double roller compaction granulation?
With these designs and structures, the double roller extrusion pelletizer makes high quality pellets. The pellets’ hardness is up to 15-20N. And the final products’ yield is up to 95%. You can use this machine to start a small scale fertilizer process line.
Three Tips for You to Choose the Best Double Roller Granulation Machine
How do you know double roller granulator is the best one for you? How to make the double roller extrusion granulators produce fertilizer quickly? There are some points for you to master later.
Understand what raw materials you have.
What raw materials you have and what kind of fertilizer you want to granulate are on your choices. For instance, if you have zinc sulfate,potassium sulphate(SOP), potassium chloride, ammonia chloride, ammonia sulfate, magnesium sulfate, sodium chloride, etc, then a double roller extrusion granulator machinery will be your best choice. It can make the products’ quality comply with the technical index requirements of compound fertilizer.
How a double roller granulating equipment works?
The roller compactor adopts dry granulation. Dry granulation is different from wet granulation. You needn’t put adhesive into the materials, and there is no need to increase the moisture content. It granulates under the normal temperature. The raw materials’ moisture is 5-10%. In this way, there is also no need for drying the formed granules, which cuts a lot of cost in your production. Besides, as the friction coefficient between the materials and the rollers is small, the energy cost is also much lower. You can start your compound fertilizer double roller granulation plant environmental-friendly.
Choosing the right model for your business is easy.
What’s your expected capacity for a double roller extrusion pellet making machine? In our factory, there are mainly three models for you to choose from. They all can process 3-10 mm pellets.
Firstly, the SXDG-1T model makes pellets 1 ton per hour. The roller sheet size is 150*220 mm. If the pellet diameter is between 3 and 4.5 mm, the power is 11 kw; and if the diameter is larger than 4.5 mm, the power is 15 kw. It’s a small scale granulation machinery.
Secondly, the SXDG-1.5T model makes pellets 1.5 tons per hour. The roller sheet size is 150*300 mm. If the pellet diameter is between 3 and 4.5 mm, the power is 18.5 kw; and if the diameter is larger than 4.5 mm, the power is 22 kw.
Thirdly, the SXDG-2T model makes pellets 2 tons per hour. The roller sheet size is 185*300 mm. If the pellet diameter is between 3 and 4.5 mm, the power is 22 kw; and if the diameter is larger than 4.5 mm, the power is 30 kw. We can also develop larger capacity double roller granulator machine as you want.
Advantages of Double Roller Extrusion Pellet Machine Production Line
A full double roller extrusion pellet machine production line includes compost system, crush system, batching system, blending system, granulation, drying and cooling system, screen system and package system, deodorization and dust removal system. There is not too much difference between granulation machines production line. The most important reason that you and our customer before prefer a double roller extrusion pellet machine is the double rollers granulator’s unique designs and working principles.
Compared with other granulator machines, double roller granulator is much smaller and more exquisite. It takes up less space and uses less energy. When you want to make granules with it, you just need to pour the dry powder into the feed port directly. And then the rollers extrude powder into specific shapes. The powder material is compressed by mechanical pressure without any wetting agent, and the purity of the product is guaranteed. The particle hardness is high, which is more significant than other granulation methods.
Our machine’s operation is easy and automatic. There is not too much burden for you to operate it. But, how do you install the machine? How do you design the whole double roller extrusion granulator machine production line? The best answer for you is you can visit our factory directly.
In our factory, you can see how we make every part and do we turn them into a complete machine. The factory works every day to make machines for delivery. Besides, as we make a deal, you can get a detailed manual. It can teach you how to install every machine part in the later. How to maintain the machine? Or, how to solve common problems?
Looking forward to our commercial cooperation. You can have the beat machine testing experience with our double roller extrusion pellet machinery.
