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



Ring die pellet mill has big quantity as well as high ability. It appropriates for factory use and also massive production. Flat die pellet mill is small as well as portable. It has reduced ability, ideal for residence usage and also small production. The rate of flat die pellet mill is a lot lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed receptacle, a top cupboard, a discharge outlet, a spindle box, transmission, a transmission shaft, an electrical control cabinet, an electrical motor, a engine base, as well as 4 wheels, etc.



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



The core parts: roller and 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 cabinet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller as well as flat die is made from remarkable alloy steel, whose firmness is 55-60 HRC.



There are many openings on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm and 10mm are one of the most usual types. They recognize the most effective compression proportion with a lot of experiments, suitable for greater than 30 sort of materials.



The clearance between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer forms. There are 2 adjusting nuts on the side of the pellet mill, you can readjust the clearance to adjust to different materials.



Exactly how does a flat die pellet equipment job?

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



When you start the pellet equipment, the electric motor runs and bring along the main shaft via the gearbox. Journalism roller is mounted on the major shaft, so it turns around the primary shaft. On the other hand, the rollers rotate around the roller shaft.



The revolving press forms solid pressure as well as press the raw materials into the holes on the flat die. sheep feed pellet machine obtain molded in these holes. When they are squeezed out, they become strong cyndrical tubes. Meanwhile, the solid friction between roller and die heat up the raw materials to over 80 ° C, where the lignin and fibers get soft. They increase the sticky force of materials.



The diameter of the pellets is established by the opening dimension of the flat die, while the size is determined by the slicer under the flat die. When the biomass pellets appear in the shape of cyndrical tubes, the slicer under the flat die reduced them into particular size. You can readjust the setting of slicer to change the size.



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




Two kinds of flat die pellet machine

Flat die pellet mill can be classified right into roller-turned type and also die-turned kind. The previous one has its flat die mounted on the major shaft. When the equipment works, the flat die rotates and the roller keep still. The later one has the press roller installed on the main shaft. The roller revolves with the major shaft, while the flat die keep still.



Roller-turned type adopts much more reliable framework. It has larger capability and more durable gearbox. However Die-turned type is extra small and also mobile, with reduced cost. Of course, both of them have the ability to make top notch pellets.



Benefits as well as weakness of flat die pellet machine

Apartment die pellet mill has straightforward structure. It is little, light and also portable. The cost is a lot less than ring die pellet equipment It is simple to run and also maintain. You can observe the pelletizing procedure and also address any type of mistake in time. So it is prominent with farmers, house users, and also little fuel manufacturing plant.



The flat dies are using parts, you need to replace it routinely. Yet it can be utilized with both sides. You can turn it over when one side has actually worn. In this way you can extend their working life and reduce price.



On the other hand, the moving distance are different in the inner and also external side of roller, which trigger the slide of rollers and abrasion on the flat die. Currently, many flat die pellet equipment adopt tapered roller to solve this problem. TICO flat die pellet equipment adopts tapered roller and premium alloy steel in the flat die.

Besides, the contact location of roller and flat die is smaller sized than ring die pellet equipment, so the manufacturing capability and also developing rate is lower.



Exactly how does a ring die pellet equipment job?

Structure of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller and also ring die, release port, electric motor, gearbox, stand.



The ring die pellet equipment is driven by a direct-connected electric motor. https://satellitesandsirens.com/poultry-pellet-machine/ connect with the gearbox through a shaft combining. The gearbox bring along the major shaft, as well as the major shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed raw materials into the ring die pellet machine with the receptacle, they are sent to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials intends to enhance the sticky pressure and also forming rate.



Then, the refined resources will certainly be transferred to the pelletizing closet. Under the centrifugal pressure, they are distributed 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 also high pressure cause physical and chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they end up being strong cylindrical sticks. The sticks grow longer, up until they are cut by the slicer outside the ring die. After that the pellets fall down as well as appear via the outlet.



2 types of ring die pellet machine

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



In the straight kind, the ring die is placed up and down. When basic materials fall down from the conditioner, they are fed right into the ring die horizontally by a forced feeder. In the vertical kind, the ring die is placed flat. The feed hopper is right above the ring die, and the raw materials falls into the ring die straight.



In the upright ring die pellet equipment, both the roller as well as ring die revolve. They form centrifugal pressure as well as disperse raw materials evenly. 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.



Advantages and weakness of ring die pellet equipment.

Ring die pellet mill includes high ability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet machine, the ability 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 more suitable.



Due to the high manufacturing, the power consumption per unit is reduced. The abrasion between roller and also die is smaller. The procedure as well as maintenance is very easy. The pellets are uniform in dimension.
