Double roller granulator is famous with dry type granulation in fertilizer production industry. It requires that your materials contain moisture under 5%. Moreover, the roller granulator is suitable for manufacturing high, medium, and low concern of special compound fertilizer, like dap fertilizer production, npk and urea fertilizer making.
Double roll extruding granulator is the key equipment in compound fertilizer production. You can change the shape of the fertilizer by assembling different rollers. Reasonable design, low energy consumption, can perfectly meet your requirements in the compound fertilizer granulation process.
In general, a roller extrusion granulator includes 4 main parts. They are rack section, driving part, extrusion granulating part, crushing and separating part. Now Huaqiang experts will give you a detailed information as follows.
*Rack section is an over all structure, which is made by high-quality carbon steel plate. All other detailed parts need assembling in the rack section. Besides, there are holes around the machine. That is easy for discharging and transporting.
*Driving part refers to that motor drives the belt pulley, triangle belt and speed reducer. This part mainly provides force during double roller granulator working.
*Extrusion granulating part is the key section in a roller granulation machine. There have two roller sheets in a complete double roller pelletizer, which will press your powder materials into big tablets.
*Crushing and separating part is to crush the extruded big tablets into uniform pellets. Then separating unqualified fertilizer granules, which need you put them into granulating part again.
If you have any confusion or questions, please contact us in time. Our experts will give you more detailed introduction.
Recently,Huaqiang Heavy designs a new model in extrusion granulator. Compared with the traditional roller extruding pelletizer, our
new type double roller pelletizing machine has the following 5 stunning characteristics:
*The feeding inlet is added mixing device to ensure evenly feeding with uniform speed.
*The main frame of the box in double roller extrusion pelletizer is equipped with self cleaning device.That efficiently prevents materials from sticking to the roller sheets.
*Adjusting roller sheet adopts adjusting spline inside the gear, which ensure that the pair is neat and not misplaced.
*The adjustment of roller gap employs step-by-step variable gear adjustment. That makes sure that the clearance is well
proportioned.
*The operation is more convenient and maintenance is easier.
After starting the machine, the motor will drive the pulley, V-belt, and reducer, and then the fertilizer pelleting machine will start working. The mixed powdered feedstock is then fed into the extrusion pelleting section through the feed hopper, and the two rollers will squeeze the air out of the powdered material, cutting the feedstock into sheet-like pieces under strong pressure.
The extruded material below will go into the crushing section inside the two-roll granulator, the large tablets will be crushed into the desired fertilizer particles, and the roller granulator will discharge your qualified granular fertilizer, allowing the powder to return to granulation again.
*Wide application to all kinds of raw materials. You can not only use double roller process machine in fertilizer pellets producing. But it is perfectly used to make pellets in medicine, chemical, metallurgy, coal and fodder.
*Less investment. Extrusion granulator machine making fertilizer pellets in room temperature. Thus, you do not buy fertilizer dryer and cooler machine.
*No waste pollution discharging. Our roller pelletizer adopts electricity as the main power. Therefore, there will be less pollution to the environment.
*High granulating rate. Double roller extrusion granulator has over 90% balling rate. Moreover, it is efficiently for difficulty in granulating materials.
*Easy operation and maintenance. Huaqiang applies advance technology in making double roller fertilizer pelletizer.Besides, with the feature of high automated, it is easy to operate.
Although the fertilizer granulator is a key equipment in the production process of fertilizer pellets, some auxiliary fertilizer facilities are also essential. To be honest, if you choose a two-roll granulator as your fertilizer granulation equipment, you also need a fertilizer crusher, a fertilizer mixer and a fertilizer baler.
Fertilizer crusher is to crush solid materials into fine powder, which is the primary preparation of granulated fertilizer.
A suitable fertilizer mixer should then be selected for secondary preparation to carry out powdered fertilizer granulation, mixing the fine powder evenly with all other matching materials.
The fertilizer packaging machine is designed to quickly pack qualified granular fertilizer into bags. As long as these fertilizer production facilities are effectively coordinated, fertilizer production efficiency can be greatly improved.
What should you pay attention to in order to longer service life of Huaqiang's roller extrusion granulator?
Huaqiang experts based on more than 30 years of experience, summed up some experience in the use of double roll granulator, there are several tips below, can help you to use our double roll granulator for a long time.
*When you are going to start the machine, please firstly confirm there is no feeding materials inside of roller pelletizing machine.
*Before feeding your materials into double roller extrusion granulator, there should no materials with iron. Because the iron will destroy your roller sheets.
*Every 7 days, you should wipe dry butter in the chain and sprocket wheels inside of fertilizer press granulator.
*Before using speed reducer, it is required to add butter into belt pulley. Moreover, every 4 months, you need to add once more.
