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



Ring die pellet mill has huge quantity and high capacity. It is suitable for factory usage as well as massive manufacturing. Flat die pellet mill is small and mobile. It has reduced capability, ideal for house usage and small-scale production. The rate of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, an upper closet, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electric control cupboard, an electric motor, a engine base, as well as 4 wheels, etc.



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



The core components: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are installed in the upper closet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. floating feed making machine have grooves on the surface area. The roller and also flat die is constructed from exceptional alloy steel, whose firmness is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most usual kinds. They understand the very best compression proportion with a large number of experiments, ideal for more than 30 type of materials.



The clearance between the roller and flat die is 0.1-0.3 mm. This is where the raw product layer kinds. There are 2 readjusting nuts on the side of the pellet mill, you can change the clearance to adapt to various materials.



Exactly how does a flat die pellet equipment work?

When you feed basic materials into the pellet equipment via the receptacle, they fall on the flat die and also spread over it under the feature of roller.



When you start the pellet equipment, the electrical motor runs as well as bring along the primary shaft via the transmission. Journalism roller is mounted on the major shaft, so it revolves around the primary shaft. On the other hand, the rollers rotate around the roller shaft.



The turning press kinds solid stress as well as press the raw products right into the holes on the flat die. The raw materials obtain formed in these openings. When they are squeezed out, they come to be solid cyndrical tubes. Meanwhile, the solid friction in between roller and also die warm up the raw products to over 80 ° C, where the lignin as well as fibers obtain soft. They boost the glue pressure of materials.



The size of the pellets is identified by the hole size of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets appear in the form of cylinders, the slicer under the flat die cut them into particular length. You can change the placement of slicer to alter the length.



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



2 kinds of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned type and also die-turned type. The former one has its flat die mounted on the major shaft. When the equipment functions, the flat die rotates as well as the roller keep still. richi pellet mill has the press roller set up on the major shaft. The roller rotates with the main shaft, while the flat die maintain still.



Roller-turned kind takes on much more efficient structure. It has bigger ability and even more resilient transmission. Yet Die-turned kind is extra little and mobile, with lower cost. Obviously, both of them have the ability to make premium pellets.



Benefits as well as weak point of flat die pellet equipment

Flat die pellet mill has straightforward framework. It is little, light and portable. The cost is much lower than ring die pellet equipment It is simple to run and also preserve. You can observe the pelletizing process as well as resolve any fault in time. So it is preferred with farmers, home users, as well as tiny fuel production plant.



The flat dies are using components, you require to replace it routinely. Yet it can be utilized with both sides. You can transform it over when one side has actually broken. By doing this you can extend their functioning life and also reduce price.



On the other hand, the moving range are different in the internal and also outer side of roller, which create the slide of rollers as well as abrasion on the flat die. Presently, many flat die pellet machine adopt conical roller to address this issue. TICO flat die pellet equipment takes on tapered roller as well as exceptional alloy steel in the flat die.

Besides, the contact area of roller as well as flat die is smaller than ring die pellet machine, so the production ability and creating price is lower.



How does a ring die pellet equipment job?

Framework of ring die pellet equipment

A ring die pellet machine is made up of a screw feeder, conditioner, roller and also ring die, discharge port, electric motor, transmission, stand.



The ring die pellet equipment is driven by a direct-connected motor. The motor connect with the transmission through a shaft coupling. The transmission bring along the major shaft, and also the major shaft bring along the rollers. So the roller began to turn inside the ring die.



When you feed raw materials into the ring die pellet machine with the hopper, they are sent to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials aims to enhance the sticky pressure and also creating price.



Then, the processed raw materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal pressure, they are dispersed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The heat and high pressure cause physical and chemical modifications to the raw materials.



When they are ejected from the ring die, they become strong cylindrical sticks. The sticks expand longer, up until they are reduced by the slicer outside the ring die. Then the pellets drop and come out through the outlet.



Two sorts of ring die pellet machine

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



In the horizontal kind, the ring die is positioned up and down. When basic materials drop from the conditioner, they are fed right into the ring die flat by a forced feeder. In the vertical type, the ring die is placed flat. The feed receptacle is right above the ring die, as well as the raw products comes under the ring die directly.



In the vertical ring die pellet equipment, both the roller and also ring die turn. They form centrifugal force and disperse raw materials uniformly. In the straight ring die pellet machine, only the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Advantages and also weakness of ring die pellet machine.

Ring die pellet mill includes high capacity. The production per hr is from 800kg to 20t. When it comes to flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you production requirement is under 800kg, you would certainly better pick flat die pellet equipment, or ring die pellet equipment is better.




Due to the high manufacturing, the power intake each is low. The abrasion in between roller and die is smaller sized. The operation and also upkeep is easy. The pellets are consistent in size.
