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



Ring die pellet mill has large volume as well as high ability. It is suitable for manufacturing facility usage as well as large manufacturing. Apartment die pellet mill is tiny as well as mobile. It has reduced capability, ideal for home usage as well as small production. The cost of flat die pellet mill is much lower than ring die pellet mill



Framework of flat die pellet mill.

From top to bottom, a flat die pellet mill is made up of a feed receptacle, a top closet, a discharge outlet, a spindle box, transmission, a transmission shaft, an electric control cabinet, an electrical motor, a engine base, as well as 4 wheels, etc.



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



The core parts: roller and also flat die

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



There are numerous holes on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are one of the most typical types. They understand the very best compression proportion with a great deal of experiments, appropriate for more than 30 kinds 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 adjusting nuts on the side of the pellet mill, you can adjust the clearance to adjust to various materials.



Exactly how does a flat die pellet machine work?

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



When you start the pellet machine, the electrical motor runs and bring along the primary shaft via the gearbox. Journalism roller is mounted on the primary shaft, so it revolves around the major shaft. On the other hand, the rollers revolve around the roller shaft.



The revolving press kinds solid stress and press the raw materials into the holes on the flat die. The raw products obtain built in these holes. When they are squeezed out, they end up being solid cylinders. On the other hand, the strong friction 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 sticky force of products.



The diameter of the pellets is determined by the hole size of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the form of cyndrical tubes, the slicer under the flat die reduced them into particular size. You can readjust the setting 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 electrical outlet.



Two types of flat die pellet equipment

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



Roller-turned kind adopts a lot more reliable framework. It has larger ability as well as even more sturdy gearbox. But Die-turned kind is extra tiny and also mobile, with reduced price. Certainly, both of them have the ability to make top quality pellets.



Advantages and weak point of flat die pellet machine

Flat die pellet mill has basic structure. It is tiny, light as well as portable. The cost is much less than ring die pellet machine It is easy to operate as well as maintain. You can observe the pelletizing process and also solve any type of mistake in time. So it is prominent with farmers, residence users, and also small fuel production plant.



The flat dies are wearing parts, you require to change it regularly. However it can be used with both sides. You can transform it over when one side has actually broken. By doing check can extend their functioning life and decrease price.



On the other hand, the relocating range are different in the inner and also outer side of roller, which create the slide of rollers and also abrasion on the flat die. Currently, numerous flat die pellet machine take on tapered roller to address this issue. TICO flat die pellet equipment embraces tapered roller and premium alloy steel in the flat die. explanation listed below to get a fast quote!



Besides, the contact area of roller and flat die is smaller than ring die pellet machine, so the manufacturing ability as well as forming rate is reduced.




How does a ring die pellet machine work?

Framework of ring die pellet machine

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



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



When you feed resources into the ring die pellet machine with the receptacle, they are transferred to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw products intends to improve the glue pressure and creating price.



After that, the refined raw materials will certainly be sent to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the internal side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature and high pressure reason physical as well as chemical changes to the raw products.



When they are squeezed out from the ring die, they end up being strong cylindrical sticks. The sticks expand much longer, till they are reduced by the slicer outside the ring die. Then the pellets fall down and also come out through the electrical outlet.



2 sorts of ring die pellet equipment

According to different placements of the ring die, there are vertical ring die pellet machine and also straight ring die pellet machine.



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



In the vertical ring die pellet equipment, both the roller and ring die turn. They create centrifugal force and also distribute resources consistently. In the straight ring die pellet machine, 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 equipment.

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



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