Notes

Exactly how does a wood pellet equipment work?<br>
Typically, wood pellet machine can be classified right into flat die pellet machine and ring die pellet machine.



Ring die pellet mill has huge volume and high capacity. It appropriates for manufacturing facility usage as well as large production. Flat die pellet mill is tiny and mobile. It has reduced ability, appropriate for house use and also small-scale manufacturing. The rate of flat die pellet mill is a lot less than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed hopper, a top cabinet, a discharge outlet, a pin box, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, and so on.



The electric motor can be replaced by a diesel motor, gas engine, or a PTO port.



The core components: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are mounted in the top closet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller as well as flat die is made of remarkable alloy steel, whose solidity is 55-60 HRC.



There are many openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are one of the most typical kinds. They realize the best compression ratio with a multitude of experiments, suitable for greater than 30 type of materials.




The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer kinds. There are small wood pellet making machine changing nuts on the side of the pellet mill, you can adjust the clearance to adapt to different materials.



Exactly how does a flat die pellet equipment job?

When you feed resources right into the pellet machine via the receptacle, they fall on the flat die as well as spread over it under the feature of roller.



When you begin the pellet equipment, the electrical motor runs and also bring along the primary shaft via the transmission. Journalism roller is mounted on the main shaft, so it revolves around the primary shaft. Meanwhile, the rollers rotate around the roller shaft.



The rotating press types strong pressure and press the raw products right into the holes on the flat die. The raw materials get built in these openings. When they are ejected, they end up being strong cyndrical tubes. Meanwhile, the strong friction in between roller and also die warm up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They enhance the sticky force of products.



The diameter of the pellets is determined by the hole size of the flat die, while the size is determined by the slicer under the flat die. When the biomass pellets appear in the form of cylinders, the slicer under the flat die reduced them into specific size. You can adjust the setting of slicer to change the length.



After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal pressure, the pellets are sent out though the discharge electrical outlet.



Two sorts of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned type as well as die-turned type. The former one has its flat die installed on the primary shaft. When the equipment works, the flat die revolves as well as the roller keep still. The later one has the press roller mounted on the main shaft. The roller turns with the primary shaft, while the flat die maintain still.



Roller-turned kind embraces extra effective framework. It has bigger ability and even more resilient gearbox. But Die-turned kind is a lot more tiny and portable, with lower cost. Obviously, both of them have the ability to make premium pellets.



Advantages as well as weak point of flat die pellet equipment

Apartment die pellet mill has basic framework. It is little, light and mobile. The expense is much lower than ring die pellet machine It is very easy to run and also preserve. You can observe the pelletizing process and fix any type of mistake in time. So it is popular with farmers, home users, as well as tiny fuel manufacturing plant.



The flat dies are putting on components, you require to change it consistently. But it can be used with both sides. You can transform it over when one side has actually broken. In this way you can prolong their functioning life and also lower cost.



On the other hand, the relocating range are different in the internal and also outer side of roller, which create the slide of rollers and abrasion on the flat die. Presently, many flat die pellet machine take on tapered roller to address this trouble. TICO flat die pellet equipment takes on tapered roller and also premium alloy steel in the flat die.

Besides, the call area of roller as well as flat die is smaller sized than ring die pellet equipment, so the manufacturing ability as well as creating rate is reduced.



Just how does a ring die pellet machine work?

Framework of ring die pellet equipment

A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, discharge port, electric motor, transmission, pedestal.



The ring die pellet machine is driven by a direct-connected motor. The motor get in touch with the transmission via a shaft coupling. The gearbox bring along the primary shaft, as well as the main shaft bring along the rollers. So the roller started to turn inside the ring die.



When you feed resources into the ring die pellet equipment via the receptacle, they are transferred to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw materials intends to enhance the glue force and developing rate.



After that, the processed raw materials will certainly be transmitted to the pelletizing cabinet. Under the centrifugal pressure, they are distributed on the internal side of the ring die. The roller press the raw materials into the holes on the ring die. The heat and also high pressure cause physical and also chemical adjustments to the raw products.



When they are ejected from the ring die, they end up being solid round sticks. The sticks grow much longer, till they are reduced by the slicer outside the ring die. Then the pellets fall down and also come out with the outlet.



2 kinds of ring die pellet equipment

According to different placements of the ring die, there are vertical ring die pellet equipment as well as straight ring die pellet equipment.



In the straight type, the ring die is placed vertically. When raw materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical type, the ring die is placed flat. The feed receptacle is right over the ring die, and also the raw products falls into the ring die straight.



In the upright ring die pellet equipment, both the roller and ring die turn. They create centrifugal force as well as disperse basic materials uniformly. In the horizontal ring die pellet equipment, only the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Benefits and weakness of ring die pellet machine.

Ring die pellet mill features high ability. The production per hour is from 800kg to 20t. As for flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you production demand is under 800kg, you 'd much better choose flat die pellet machine, or ring die pellet equipment is more suitable.



Due to the high production, the power usage each is low. The abrasion between roller as well as die is smaller. lily pellet extruder and also upkeep is simple. The pellets are uniform in dimension.
