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



Ring die pellet mill has huge volume as well as high capability. It is suitable for factory use and large manufacturing. Flat die pellet mill is tiny as well as mobile. It has reduced capability, ideal for home use and also small-scale manufacturing. The price of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

From top to bottom, a flat die pellet mill is composed of a feed hopper, a top cupboard, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electric control cupboard, an electric motor, a engine base, and 4 wheels, etc.



The electrical motor can be changed by a diesel engine, gasoline engine, or a PTO connector.



The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller and also a flat die. They are mounted in the upper cabinet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and flat die is made from remarkable alloy steel, whose hardness is 55-60 HRC.



There are lots of openings on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and also 10mm are the most usual kinds. They recognize the very best compression ratio with a large number of experiments, ideal for more than 30 kinds of products.



The clearance between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer types. There are 2 adjusting nuts on the side of the pellet mill, you can readjust the clearance to adapt to different materials.



How does a flat die pellet equipment work?

When you feed resources into the pellet equipment with the hopper, they fall on the flat die as well as spread over it under the feature of roller.



When you begin the pellet equipment, the electric motor runs and bring along the major shaft via the transmission. Journalism roller is set up on the major shaft, so it turns around the primary shaft. At the same time, the rollers turn around the roller shaft.



The turning press types strong pressure as well as press the raw products right into the holes on the flat die. The raw products obtain formed in these holes. When they are ejected, they become solid cylinders. Meanwhile, the strong rubbing in between roller and die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They increase the sticky force of materials.



The diameter of the pellets is established by the hole size of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets come out in the form of cylinders, the slicer under the flat die reduced them into specific size. https://www.scoop.it/u/richi-machinery can change the setting of slicer to change the size.



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



Two kinds of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned type and also die-turned kind. The former one has its flat die mounted on the major shaft. When the machine functions, the flat die revolves as well as the roller maintain still. The later one has journalism roller set up on the main shaft. The roller turns with the major shaft, while the flat die keep still.



Roller-turned kind embraces a lot more reliable framework. It has larger capacity and even more long lasting gearbox. However Die-turned type is a lot more tiny and portable, with reduced cost. Of course, both of them are able to make high-grade pellets.



Advantages and weakness of flat die pellet equipment

Apartment die pellet mill has basic framework. It is tiny, light and portable. The expense is much less than ring die pellet machine It is simple to run and maintain. You can observe the pelletizing process and solve any type of fault in time. So it is preferred with farmers, home individuals, and also little gas production plant.



The flat dies are using parts, you require to replace it on a regular basis. Yet it can be used with both sides. You can turn it over when one side has actually worn out. In this way you can prolong their working life as well as decrease expense.



On the other hand, the relocating range are various in the internal and outer side of roller, which trigger the slide of rollers and also abrasion on the flat die. Presently, numerous flat die pellet equipment take on tapered roller to fix this issue. TICO flat die pellet machine adopts conical roller and premium alloy steel in the flat die.

Besides, the get in touch with location of roller as well as flat die is smaller sized than ring die pellet machine, so the production capability and creating rate is reduced.



Exactly how does a ring die pellet equipment job?

Structure of ring die pellet machine


A ring die pellet equipment is made up of a screw feeder, conditioner, roller as well as ring die, discharge port, electrical motor, transmission, stand.



The ring die pellet equipment is driven by a direct-connected electric motor. The electric motor connect with the transmission with a shaft combining. The gearbox bring along the main shaft, as well as the primary shaft bring along the rollers. So https://www.linkedin.com/in/carmen-huang-105ba9264/ started to revolve inside the ring die.



When you feed resources right into the ring die pellet equipment with the receptacle, they are sent to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw products aims to boost the sticky force as well as forming rate.



After that, the processed basic materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal pressure, they are distributed on the inner side of the ring die. The roller press the raw products into the holes on the ring die. The heat and high pressure reason physical and chemical adjustments to the raw materials.



When they are ejected from the ring die, they come to be strong round sticks. The sticks expand much longer, up until they are reduced by the slicer outside the ring die. After that the pellets fall down as well as appear with the electrical outlet.



Two sorts of ring die pellet machine

According to various positionings of the ring die, there are vertical ring die pellet machine as well as horizontal ring die pellet equipment.



In the straight type, the ring die is put vertically. When raw materials fall down from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the upright kind, the ring die is positioned horizontally. The feed receptacle is right over the ring die, and also the raw materials falls into the ring die straight.



In the upright ring die pellet machine, both the roller as well as ring die rotate. They develop centrifugal force and distribute raw materials evenly. In the horizontal ring die pellet machine, only the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Advantages as well as weakness of ring die pellet machine.

Ring die pellet mill includes high capacity. The production per hr is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you production demand is under 800kg, you would certainly better choose flat die pellet equipment, or ring die pellet equipment is preferable.



Because of the high production, the power intake per unit is low. https://pelletrichi.hatenablog.com/entry/2023/03/10/144302 in between roller and die is smaller sized. The procedure and also maintenance is easy. The pellets are consistent in size.
