Centrifugal ring die pellet machine is one of the preferred products in the biomass energy industry, a pelletizing equipment for pressing various fuel pellets. Centrifugal ring die pellet machine is a pellet machine specially built by our company for the energy industry.

This product is suitable for pressing materials that are difficult to bond and form, such as: rice husks, sunflower seed husks, peanut husks and other melon and fruit husks, crop straws; branches, tree stalks, bark and other wood scraps; rubber, Cement, ash and other chemical raw materials. Used in feed factories, wood processing factories, fuel factories, fertilizer factories, chemical factories, etc., it is an ideal compression and densification molding equipment with low investment, good effect and good effect.

The situation of ring die granulator and centrifugal high-efficiency granulator is briefly explained, but what is the difference between these two series of machines when making fuel pellets?

1. In terms of feeding method:

The ring die granulator adopts mechanical forced feeding, high-speed rotation and centrifugal distribution into the granulating chamber, and the material is distributed by the scraper. The centrifugal high-efficiency granulator enters the pressing chamber vertically by the weight of the material itself, which can feed the material evenly, and can make full use of the centrifugal effect to distribute the material evenly around.

2. In terms of pellet machine pressure:

In the mold with the same diameter, the diameter of the ring die pressing wheel is limited by the diameter of the ring die, so the pressure is limited; in time, the machine was modified to increase the pressure in the case of pressing the wood pellet machine, but the effect was not very satisfactory. , the bearing is easily broken when the pressure is increased. The diameter of the pressure roller of the centrifugal high-efficiency granulator is not limited by the diameter of the mold, and the space for the built-in bearing can be enlarged. The large bearing is selected to enhance the bearing capacity of the pressure roller, which not only improves the pressing force of the pressure roller, but also prolongs the service life. .

3. In terms of discharging method:

The ring die has a high rotation speed, and the breakage rate is high when the material is discharged; because the long-term operation on one side will cause poor stability, because the machine itself is heavy on one side and light on the other, while the centrifugal high-efficiency granulator is a low-speed granulator, and the material is fed vertically , Optimize the design of the fuselage, and use a super-strong filter lubrication return system.
Fourth, the pressure wheel adjustment method:

The ring die granulator uses two screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure; the flat die granulator uses a threaded screw rod m100 center adjustment mechanism, with a jacking force of 100 tons, stable falling, soft touch, and pressure. evenly. There are two ways of rotating manual and hydraulic automatic adjustment. Adjustment of the gap between the wheel and the die plate of the centrifugal high-efficiency granulator: remove the feed cover, unscrew the hollow bolt of the lubricating oil pipe at the end of the pressure wheel shaft, and adjust the front and rear nuts, so that the pressure wheel shaft can be rotated, and the pressure wheel assembly and the die plate can be adjusted. After the adjustment is completed, tighten the hollow bolt to connect the lubricating oil circuit.

In order to better serve customers, the centrifugal high-efficiency pellet machine also adds a dust cover to improve the production and processing of pellets, and isolate the dust, which protects the machine and prolongs the service life of the machine.
Centrifugal ring die pellet mill has the following advantages:

1. High-precision involute cylindrical helical gears are used for direct transmission, and the transmission efficiency is as high as 98%. Normalizing heat treatment after water forging of the transmission gear blanks improves the hardness of the tooth surface; the tooth surface is treated with carburizing, and the carburizing layer is deep Up to 2.4mm enhances wear resistance and prolongs the service life of components; the hardened tooth surface is processed by silent fine grinding and trimming process, which makes the operation quieter and more stable.

2. The main shaft and the conjoined hollow shaft are made of alloy structural steel imported from Germany after water forging, rough turning, heat treatment, fine turning and fine grinding. The structure is reasonable and the hardness is uniform, which improves the fatigue resistance and wear resistance of the parts, and is safe for safety. Operation provides more reliable guarantee.

3. The main box is made of high-quality steel, with uniform thickness and tight structure; it is carefully processed by a CNC machining center imported from Switzerland, with zero error in machining accuracy. It provides stronger support for normal operation.

4. The bearings and oil seals used in the transmission part are made of high-precision bearings imported from Japan and wear-resistant and temperature-resistant fluororubber oil seals imported from the United States, and a lubricating oil return system is specially added, the oil circuit is circulated and cooled, and oil is lubricated automatically at regular intervals. Ensure that the bearings are fully lubricated, Safer and more reliable operation.

5. The bearings used in the particle forming system are all high-quality silent bearings, and the thin oil circulation cooling and lubrication system is added, so that the bearing service life is longer and the operation is safer.

6. The ring die is made of high-grade stainless steel and high-nickel steel. The unique compression ratio design is reasonable, so that the product quality is better, the service life of the ring die is longer, and the production cost is greatly reduced.

7. Centrifugal ring die pellet machine has undergone hundreds of tests and demonstrations, and finally determined a stable, reliable, efficient, safe and economical model, and the equipment can achieve continuous operation for 11-23 hours.
