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



Ring die pellet mill has big quantity and also high capability. It is suitable for factory usage as well as large-scale manufacturing. Apartment die pellet mill is tiny and also portable. It has reduced capability, suitable for home usage and also small-scale production. The price of flat die pellet mill is much lower than ring die pellet mill



Framework of flat die pellet mill.

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



The electrical motor can be changed by a diesel engine, gas engine, or a PTO adapter.



The core components: roller and flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are mounted in the top cabinet. There are 2-4 rollers installed 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 superior alloy steel, whose hardness is 55-60 HRC.



There are several holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most usual kinds. They realize the very best compression proportion with a multitude of experiments, ideal for greater than 30 kinds of products.



The clearance between the roller and flat die is 0.1-0.3 mm. This is where the raw material layer kinds. There are 2 changing nuts on the side of the pellet mill, you can adjust the clearance to adjust to various products.



Just how does a flat die pellet equipment job?

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




When you begin the pellet equipment, the electrical motor runs as well as bring along the primary shaft through the gearbox. Journalism roller is mounted on the main shaft, so it turns around the primary shaft. On the other hand, the rollers revolve around the roller shaft.



The revolving press types strong pressure as well as press the raw products into the holes on the flat die. The raw materials obtain molded in these holes. When they are squeezed out, they come to be strong cylinders. Meanwhile, the solid friction in between roller as well as die warm up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They raise the adhesive pressure of products.



The diameter of the pellets is established by the opening size of the flat die, while the size is figured out 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 specific size. You can readjust 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 though the discharge electrical outlet.




Two kinds of flat die pellet equipment

Apartment die pellet mill can be classified right into roller-turned type as well as die-turned type. The previous one has its flat die set up on the primary shaft. When the equipment works, the flat die rotates as well as the roller maintain still. The later one has the press roller mounted on the major shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned type takes on extra effective framework. It has larger capacity as well as more sturdy gearbox. Yet Die-turned type is more small and also mobile, with lower price. Certainly, both of them have the ability to make top quality pellets.



Advantages and also weakness of flat die pellet machine

Apartment die pellet mill has straightforward framework. It is small, light and also mobile. The cost is much lower than ring die pellet equipment It is simple to run as well as maintain. You can observe the pelletizing process and address any type of fault in time. So richi pellet mill is prominent with farmers, home customers, and little gas production plant.



The flat dies are putting on components, you require to replace it on a regular basis. Yet it can be utilized with both sides. You can turn it over when one side has actually worn. This way you can expand their working life and reduce cost.



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

Besides, the call location of roller as well as flat die is smaller than ring die pellet equipment, so the manufacturing capacity and also creating rate is reduced.



Exactly how does a ring die pellet equipment work?

Structure of ring die pellet machine

A ring die pellet equipment is composed of a screw feeder, conditioner, roller and also ring die, release port, electrical motor, gearbox, stand.



The ring die pellet machine is driven by a direct-connected electric motor. The motor connect with the gearbox via a shaft coupling. The gearbox bring along the primary shaft, and the main shaft bring along the rollers. So the roller began to revolve inside the ring die.



When you feed raw materials right into the ring die pellet equipment via the hopper, they are transmitted to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw materials aims to improve the sticky force and creating price.



After that, the refined raw materials will 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 right into the holes on the ring die. The heat and high pressure cause physical and also chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they become solid cylindrical sticks. The sticks expand longer, till they are cut by the slicer outside the ring die. Then the pellets drop and also appear through the outlet.



2 kinds of ring die pellet machine

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



In the horizontal type, the ring die is placed vertically. When look what i found drop from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright type, the ring die is put flat. The feed receptacle is right over the ring die, as well as the raw materials comes under the ring die straight.



In the upright ring die pellet equipment, both the roller as well as ring die revolve. They create centrifugal force as well as distribute resources evenly. 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.



Advantages as well as weakness of ring die pellet equipment.

Ring die pellet mill features high capability. The manufacturing 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 manufacturing demand is under 800kg, you 'd better choose flat die pellet machine, or ring die pellet equipment is preferable.



Due to the high manufacturing, the power intake each is reduced. The abrasion in between roller as well as die is smaller. The procedure and also maintenance is easy. The pellets are consistent in size.
