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



Ring die pellet mill has large quantity and also high ability. It is suitable for factory usage as well as large manufacturing. Flat die pellet mill is little and also portable. It has lower capability, suitable for residence use and also small manufacturing. The price 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 hopper, a top closet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electrical control cabinet, an electric motor, a engine base, as well as 4 wheels, and so on.



The electric motor can be replaced by a diesel engine, fuel engine, or a PTO adapter.



The core components: roller as well as flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are set up in the top cupboard. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and also flat die is made of superior alloy steel, whose hardness is 55-60 HRC.



There are several openings on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are one of the most usual types. They recognize the most effective compression ratio with a great deal of experiments, appropriate for more than 30 kinds of materials.



The clearance in 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 readjust the clearance to adjust to different materials.



How does a flat die pellet machine work?

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



When you begin the pellet equipment, the electric motor runs and also bring along the primary shaft via the gearbox. The press roller is installed on the main shaft, so it turns around the major shaft. Meanwhile, the rollers rotate around the roller shaft.



The turning press types strong pressure as well as press the raw products into the holes on the flat die. The raw materials get formed in these holes. When they are squeezed out, they become strong cyndrical tubes. On the other hand, the strong friction between roller as well as die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They raise the adhesive pressure of products.



The diameter of the pellets is figured out by the opening dimension of the flat die, while the length is figured out by the slicer under the flat die. When find here come out in the form of cyndrical tubes, the slicer under the flat die reduced them into specific length. You can change the placement of slicer to alter the length.



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




2 kinds of flat die pellet equipment

Flat die pellet mill can be classified into roller-turned type as well as die-turned kind. The previous one has its flat die set up on the major shaft. When the equipment works, the flat die rotates as well as the roller keep still. The later one has the press roller mounted on the major shaft. The roller turns with the main shaft, while the flat die keep still.



Roller-turned type adopts a lot more effective framework. It has larger capacity and more resilient gearbox. However Die-turned type is much more tiny and also portable, with lower expense. Of course, both of them are able to make top quality pellets.



Benefits and weakness of flat die pellet machine

Flat die pellet mill has basic framework. It is tiny, light as well as mobile. The cost is a lot lower than ring die pellet machine It is easy to operate and keep. You can observe the pelletizing process and solve any fault in time. So it is prominent with farmers, home users, and also small gas manufacturing plant.



The flat dies are wearing parts, you need to change it frequently. Yet it can be used with both sides. You can transform it over when one side has actually broken. This way you can expand their functioning life and also reduce price.



On the other hand, the relocating range are various in the inner and also outer side of roller, which cause the slide of rollers and also abrasion on the flat die. Currently, several flat die pellet machine embrace tapered roller to fix this trouble. TICO flat die pellet equipment embraces tapered roller and also superior alloy steel in the flat die.

Besides, the call area of roller and also flat die is smaller sized than ring die pellet machine, so the production capability and creating price is lower.



Just how does a ring die pellet equipment job?

Structure of ring die pellet machine

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



The ring die pellet equipment is driven by a direct-connected motor. feed making machine price get in touch with the gearbox via a shaft combining. The transmission bring along the primary shaft, and the main shaft bring along the rollers. So the roller began to turn inside the ring die.



When you feed raw materials right into the ring die pellet machine through the receptacle, they are transmitted to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw products intends to boost the adhesive force and also forming rate.



Then, the processed resources will be sent to the pelletizing cupboard. 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 high temperature and high pressure reason physical as well as chemical modifications to the raw materials.



When they are ejected from the ring die, they end up being strong round sticks. The sticks expand longer, until they are cut by the slicer outside the ring die. Then the pellets fall down as well as appear through the electrical 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 equipment.



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



In the vertical ring die pellet equipment, both the roller and also ring die turn. They create centrifugal force and also distribute raw materials consistently. In the horizontal ring die pellet machine, only the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages as well as weakness of ring die pellet machine.

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



Because of the high production, the power consumption per unit is low. The abrasion between roller as well as die is smaller sized. The procedure as well as upkeep is simple. The pellets are consistent in size.
