Small Flat Die Pellet Machine for Organic Fertilizer and Feed
The flat die pellet mill has become the first choice for many farmers to process their manure due to its compact body and quick granulation. In addition, in the feed pelleting industry, flat die fertilizer granulators have also become the choice of many feed manufacturers. So, what makes our flat die extrusion granulator stand out from the crowd? The answer is that our flat die pellet machine has some special designs and materials, which make our flat die granulator have some advantages that other similar equipment cannot achieve. Compared with other granulators, such as disc granulator, rotary drum granulator, double roller extrusion granulator, etc., flat die pellet mill belongs to dry granulation. In addition, the flat die granulator is more suitable for small granulators for household use.
How Do We Design The Structure of Flat Die Pellet Mill?
Feed Port
From the following picture we can see, the feed port of our granulator is on the left side of the control box. The whole is round, and the opening on the top is large, which is convenient for feeding. The material of the feeding port is stainless steel to prevent the material from corroding and sticking to the wall. The material enters the granulating device vertically for the next step of granulation.
Granulating Device
Flat die extrusion granulator belongs to dry extrusion granulation. It mainly consists of rollers and molds. The mold gap can be large or small. It can produce columnar particles with a diameter of 2-8 mm. The roller is an important part of the granulating part. Since some raw materials such as sawdust, straw, etc. require a lot of pressure for extrusion. So our rollers are made of special materials, which are pressure-resistant and wear-resistant. You can choose the different mold shapes according to your needs, generally cylindrical. You can also adjust the length of the columnar particles.
Discharge Port
The discharge port is below the granulation part and is square. There is a stainless steel tray connection outside, which is convenient for receiving materials.
Gear Box
The working principle of the flat die granulator is to drive the belt and pulley through the motor, transmit it to the driving shaft through the reducer, and open the gear and the driven shaft to work synchronously.
The Wheel
Our flat die pellet machine has four wheels for easy walking. Due to the great weight of the granulator, manual transport wastes time and energy. Given the convenience of use, we design the wheel for the flat die granulator.
Control Box
The flat die granulator uses a central pressure regulating structure. It can realize mass production by automatically controlling the control box. There is an observation window on the electric control box to facilitate the inspection and maintenance of the equipment.

How Does The Flat Die Pellet Mill Process The Fertilizer?
First of all, in the driving part, the main motor drives the belt and pulley, and drives the drive shaft to work through the reducer. The split gears installed on the driving shaft are engaged with the large gear ring fixed on the body to do opposite work. Second, you need to add the material from the feed port. The material enters the granulation part due to its own gravity. Then in the granulation process, the granules are formed by the extrusion of the pressing roller and the mold. Finally, it flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, it can be achieve mass production.
In design, our flat die granulator uses two-stage transmission of belt and worm gear, which is stable in rotation and low in noise. Feeding relies on the material’s own gravity to fall to avoid clogging. The rotational speed of the main shaft is about 60 rpm, and the linear speed of the pressing roller is about 2.5 m/s. It can effectively remove the gas in the material and increase the tightness of the product. Due to the lower line speed, the noise generated during operation and the wear of components are reduced at the same time. The roller bearings are permanently lubricated and specially sealed. On the one hand, this design can prevent the lubricant from contaminating the material during the granulation process. On the other hand, it can reduce the loss of lubricant.
Why So Many Fertilizer Producer Use The SX Flat Die Extrusion Granulator?
Smooth Particle
The granular material processed by the flat die fertilizer granulator has a smooth surface and moderate hardness. The temperature rise is low during the processing, so the nutrients inside the raw materials can be better maintained reliable performance.
Low Moisture
One of the advantages of the flat die pellet mill is that the produced granules have low moisture content. Do not require drying and are easy to store. It can keep the original state for a long time in water, which greatly improves the utilization rate of materials.
Compact Structure
The overall frame of the equipment is channel steel, and the structure is practical. A variety of aperture molds are available to produce columnar particles of different diameters. The key components are alloy steel and wear-resistant materials, and the service life is long. The pressing roller uses the inclined wheel, and the two ends are the same as the inner and outer circles of the die plate. There is no dislocation friction between the rollers and the mold, which reduces the resistance and extends the service life of the mold.

How To Adjust The Flat Die Granulator?
Adjustment of Roller Gap
During the production process, it is sometimes necessary to increase the output. At this time, you can increase the spacing between the two axes. you can also increase the spacing between the drive shaft roller and the driven shaft. The steps are as follows: stop the machine, remove the frame on the two bearing seats, and adjust the adjustment plate between the two bearing seats to the desired thickness. There should be no collision between the two rollers, at least between 0.3-1 mm.
Ball and Socket Alignment
The adjustment ball socket is composed of dimples on the surface of the main roller, and there are problems of axial alignment and circumferential alignment.
Axial Alignment
Adjusted during installation. Generally speaking, adjustment is unlikely. When need adjustment, tighten or loosen the glands on both sides of the passive bearing seat to facilitate the displacement of the eccentric sleeve to correspond to the drive shaft roller.
Axial Alignment Steps
Loosen the 6 connecting bolts of the driven gear and the adjusting sleeve, and gently disassemble the adjusting sleeve and the driven gear. Since the design takes into account the adjustment of the ball and socket, and is equipped with two adjustment bolts, the misalignment can be adjusted no matter how much. Since the ball socket is too small, put the carton board between the two rollers when adjusting, and you can see whether the adjustment has achieved the goal after rolling. When correct, you can tighten 8 connecting bolts.

Things You Should Know When You Using Our Flat Die Pellet Mill
- First, when installing, install the granulator smoothly. Adjust the tightness of the belt, check whether the steering is normal, and whether the screws in various parts are loose.
- When using, you should note that there should be no hard objects such as stones and iron blocks in the raw materials, otherwise it will damage the pressing roller and the template.
- After working for more than 10 shifts (8 hours per shift), the rollers should be disassembled. You should add the high temperature resistant oil to the bearings to prolong the service life of the bearings.
- During granulation, it is strictly forbidden for the roller to idling contact with the template.
- There is no granulation and no discharge during granulation, you should remove the template to clean the holes.
- Frequently check the oil level and oil leakage of the gearbox. Change gear oil every 720 hours.
- If there are more refined fibers, you should add about 5% of the water when you process the material. If there are more refined fibers in the mixed material, the amount of water added can be reduced as appropriate, and the water will be exerted during the extrusion process.
