Just how does a wood pellet equipment job?<br>
Generally, wood pellet machine can be classified into flat die pellet equipment as well as ring die pellet equipment.



Ring die pellet mill has large quantity as well as 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, appropriate for residence usage and also small manufacturing. The price of flat die pellet mill is much less than ring die pellet mill



Framework of flat die pellet mill.


From top to bottom, a flat die pellet mill is composed of a feed hopper, an upper closet, a discharge electrical outlet, a pin box, gear box, a transmission shaft, an electric control closet, an electric motor, a engine base, and also 4 wheels, and so on.



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



The core parts: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller as well as a flat die. They are set up in the upper cupboard. There are 2-4 rollers mounted on the 2 ends of the roller shaft. cpm 3000 pellet mill have grooves on the surface area. The roller and flat die is constructed from superior alloy steel, whose solidity is 55-60 HRC.



There are many holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are the most usual kinds. They recognize the most effective compression ratio with a lot of experiments, appropriate for greater than 30 type of products.



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



Just how does a flat die pellet machine work?

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



When you start the pellet machine, the electric motor runs and also bring along the primary shaft through the transmission. The press roller is set up on the major shaft, so it turns around the main shaft. On the other hand, the rollers turn around the roller shaft.



The turning press forms solid stress as well as press the raw materials right into the holes on the flat die. The raw products obtain built in these holes. When they are squeezed out, they come to be solid cyndrical tubes. On the other hand, the solid friction between roller and also die heat up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They increase the glue force of materials.



The diameter of the pellets is identified by the hole dimension 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 cylinders, the slicer under the flat die reduced them right into certain length. You can change the placement of slicer to change the size.



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 though the discharge outlet.



Two sorts of flat die pellet equipment

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



Roller-turned kind embraces much more reliable framework. It has larger capacity and even more durable transmission. However Die-turned type is a lot more tiny and also mobile, with lower price. Certainly, both of them have the ability to make top quality pellets.



Benefits as well as weak point of flat die pellet equipment

Apartment die pellet mill has easy framework. It is small, light and portable. The cost is a lot less than ring die pellet equipment It is very easy to operate and also keep. You can observe the pelletizing process and fix any fault in time. So it is popular with farmers, house customers, as well as small gas production plant.



The flat dies are wearing parts, you need to replace it routinely. But it can be used with both sides. You can turn it over when one side has actually broken. This way you can extend their functioning life and lower expense.



On the other hand, the relocating distance are different in the internal and outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, lots of flat die pellet machine adopt conical roller to solve this issue. TICO flat die pellet machine embraces tapered roller and premium alloy steel in the flat die.

Besides, the get in touch with area of roller and also flat die is smaller than ring die pellet equipment, so the manufacturing ability as well as forming price is lower.



How does a ring die pellet machine work?

Framework of ring die pellet machine

A ring die pellet machine is composed of a screw feeder, conditioner, roller as well as ring die, release port, electric motor, gearbox, stand.



The ring die pellet machine is driven by a direct-connected motor. The motor connect with the transmission via a shaft combining. The gearbox bring along the main shaft, as well as the main shaft bring along the rollers. So special info started to revolve inside the ring die.



When you feed resources right 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 aims to improve the glue force and developing price.



Then, the refined basic materials will certainly be transmitted to the pelletizing closet. 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 heat and high pressure cause physical as well as chemical adjustments to the raw products.



When they are ejected from the ring die, they come to be strong round sticks. The sticks expand much longer, up until they are reduced by the slicer outside the ring die. Then the pellets drop and also appear via the electrical outlet.



2 sorts of ring die pellet equipment

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



In the straight kind, the ring die is placed up and down. When resources 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 horizontally. The feed hopper is right over the ring die, and the raw materials comes under the ring die straight.



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



Advantages and also weakness of ring die pellet machine.

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



Due to the high manufacturing, the power usage each is low. The abrasion between roller as well as die is smaller. The procedure and also maintenance is very easy. The pellets are consistent in dimension.
