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



Ring die pellet mill has huge volume and also high capability. It appropriates for factory usage and also massive production. Apartment die pellet mill is tiny and portable. It has lower capacity, ideal for residence 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.

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



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



The core components: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are installed in the upper closet. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller as well as flat die is made from remarkable alloy steel, whose hardness is 55-60 HRC.



There are lots of openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most usual types. They understand the very best compression ratio with a great deal of experiments, ideal for greater than 30 kinds of products.



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



Exactly how does a flat die pellet equipment work?

When you feed resources into the pellet machine via the receptacle, they fall on the flat die as well as spread over it under the function of roller.



When you start the pellet machine, the electric motor runs and also bring along the main shaft with the gearbox. Journalism roller is installed on the major shaft, so it revolves around the main shaft. Meanwhile, richi pellet mill rotate around the roller shaft.



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



The diameter of the pellets is identified by the opening dimension of the flat die, while the size is figured out by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die cut them into certain size. You can change the placement of slicer to alter the size.



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



Two types of flat die pellet machine

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



Roller-turned type takes on a lot more efficient structure. It has larger capability and more long lasting transmission. However Die-turned type is more tiny and mobile, with lower cost. Of course, both of them have the ability to make top notch pellets.




Benefits and also weak point of flat die pellet equipment

Apartment die pellet mill has simple framework. It is small, light as well as mobile. The price is much less than ring die pellet equipment It is simple to run and preserve. You can observe the pelletizing procedure as well as solve any fault in time. So it is preferred with farmers, house users, and also tiny gas production plant.



The flat dies are using parts, you require to change it consistently. However it can be made use of with both sides. You can turn it over when one side has broken. By doing this you can prolong their functioning life and decrease cost.



On the other hand, the relocating distance are various in the internal and external side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, several flat die pellet machine adopt conical roller to address this issue. TICO flat die pellet equipment adopts conical roller as well as exceptional alloy steel in the flat die.

Besides, the get in touch with location of roller and also flat die is smaller sized than ring die pellet machine, so the manufacturing capability as well as developing rate is reduced.



Exactly 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 and ring die, release port, electric motor, gearbox, stand.



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor get in touch with the gearbox via a shaft combining. The gearbox bring along the major shaft, and also the primary shaft bring along the rollers. So the roller began to turn inside the ring die.



When you feed basic materials right into the ring die pellet equipment via 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 adhesive force as well as creating price.



Then, the refined resources will be transferred to the pelletizing cabinet. Under the centrifugal pressure, they are dispersed on the inner side of the ring die. fish food extruder press the raw materials right into the holes on the ring die. The heat and high pressure cause physical as well as chemical changes to the raw materials.



When they are ejected from the ring die, they end up being solid cylindrical sticks. richi pellet expand longer, until they are cut by the slicer outside the ring die. Then the pellets fall down as well as come out via 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 type, the ring die is put vertically. When basic materials fall down from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright type, the ring die is placed horizontally. The feed hopper is right above the ring die, as well as the raw materials comes under the ring die straight.



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



Benefits and also weak point of ring die pellet machine.


Ring die pellet mill includes high capability. The manufacturing per hour is from 800kg to 20t. As for flat die pellet equipment, the ability is from 100kg/h to 1t/t. So if you manufacturing requirement is under 800kg, you 'd much better choose flat die pellet machine, or ring die pellet equipment is better.



As a result of the high manufacturing, the power consumption each is low. The abrasion between roller and also die is smaller. The procedure and also upkeep is very easy. The pellets are consistent in size.
