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



Ring die pellet mill has huge quantity and high ability. It is suitable for manufacturing facility usage as well as large-scale manufacturing. Flat die pellet mill is tiny as well as mobile. It has lower capability, suitable for house usage and small-scale manufacturing. The cost of flat die pellet mill is a lot less 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 electrical outlet, a pin box, gear box, a transmission shaft, an electric control cupboard, an electrical motor, a engine base, and 4 wheels, etc.



The electric motor can be replaced by a diesel engine, gasoline 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 also a flat die. They are installed in the top cupboard. There are Check Out Your URL -4 rollers mounted on the 2 ends of the roller shaft. animal feed pellet maker have grooves on the surface area. The roller as well as flat die is made of superior alloy steel, whose solidity is 55-60 HRC.



There are lots of holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are one of the most common types. They recognize the best compression ratio with a multitude of experiments, ideal for more than 30 sort of materials.



The clearance in between the roller as well as flat die is 0.1-0.3 mm. This is where the raw product layer types. There are 2 changing nuts on the side of the pellet mill, you can readjust the clearance to adapt to various products.



Just how does a flat die pellet machine job?

When you feed raw materials right into the pellet machine via the hopper, they fall on the flat die and also spread over it under the function of roller.



When you start the pellet machine, the electric motor runs and bring along the main shaft with the transmission. The press roller is installed on the primary shaft, so it turns around the primary shaft. Meanwhile, the rollers revolve around the roller shaft.



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



The size of the pellets is established by the opening size of the flat die, while the length 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 reduced them right into certain length. You can change the position of slicer to change the size.



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.



2 types of flat die pellet equipment

Apartment die pellet mill can be classified into roller-turned type as well as die-turned type. The previous one has its flat die installed on the main shaft. When the machine works, the flat die turns and also the roller maintain still. The later one has the press roller mounted on the main shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned type takes on much more effective structure. It has bigger capability and even more resilient gearbox. Yet Die-turned kind is a lot more small and also portable, with reduced expense. Obviously, both of them are able to make high-quality pellets.



Advantages as well as weakness of flat die pellet machine

Flat die pellet mill has straightforward structure. It is tiny, light as well as mobile. The cost is a lot lower than ring die pellet machine It is simple to operate and keep. You can observe the pelletizing procedure and address any type of mistake in time. So it is preferred with farmers, residence individuals, and little gas manufacturing plant.



The flat dies are wearing parts, you require to change it on a regular basis. Yet it can be made use of with both sides. You can transform it over when one side has actually worn. By doing this you can prolong their functioning life and also reduce cost.



On the other hand, the moving distance are various in the internal and external side of roller, which trigger the slide of rollers as well as abrasion on the flat die. Presently, several flat die pellet equipment embrace tapered roller to fix this issue. TICO flat die pellet equipment embraces tapered roller as well as premium alloy steel in the flat die.

Besides, the contact location of roller as well as flat die is smaller sized than ring die pellet machine, so the manufacturing ability as well as developing rate is lower.



How does a ring die pellet machine job?

Structure of ring die pellet equipment

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



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor connect with the gearbox through a shaft coupling. The gearbox bring along the main shaft, and also the primary 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 equipment with the receptacle, they are transmitted to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials aims to boost the sticky force and also creating price.



After that, the processed raw materials will be transferred to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature and also high pressure reason physical and chemical modifications to the raw materials.



When they are squeezed out from the ring die, they end up being solid round sticks. The sticks grow much longer, till they are cut by the slicer outside the ring die. After that the pellets drop and also appear with the outlet.



Two types of ring die pellet machine

According to various placements of the ring die, there are vertical ring die pellet equipment and horizontal ring die pellet machine.



In the horizontal kind, the ring die is put 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 kind, the ring die is positioned horizontally. The feed receptacle is right over the ring die, and the raw materials comes under the ring die directly.



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



Benefits and also weakness of ring die pellet machine.

Ring die pellet mill includes high ability. The manufacturing 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 need is under 800kg, you 'd better pick flat die pellet machine, or ring die pellet machine is more suitable.



Because of the high production, the power usage per unit is low. The abrasion between roller and die is smaller sized. The operation as well as maintenance is easy. The pellets are consistent in size.
