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



Ring die pellet mill has big volume as well as high ability. It appropriates for manufacturing facility usage and large-scale manufacturing. biomass pellet mill for sale is small and portable. It has reduced ability, ideal for house usage and also small manufacturing. The price of flat die pellet mill is a lot less than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed receptacle, an upper closet, a discharge outlet, a spindle box, gear box, a transmission shaft, an electrical control cupboard, an electrical motor, a engine base, as well as 4 wheels, and so on.



The electric motor can be changed by a diesel engine, fuel engine, or a PTO port.



The core parts: roller and also flat die

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



There are several holes on the flat die, whose diameter is from 2.5 mm to 10mm, and also 6mm, 8mm as well as 10mm are the most typical kinds. They recognize the very best compression proportion with a lot of experiments, ideal for more than 30 sort of materials.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw product layer forms. There are 2 readjusting nuts on the side of the pellet mill, you can change the clearance to adjust to various products.



Exactly how does a flat die pellet machine work?

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



When you begin the pellet machine, the electric motor runs and also bring along the major shaft via the transmission. Journalism roller is installed on the primary shaft, so it turns around the major shaft. At the same time, the rollers rotate around the roller shaft.



The rotating press forms solid stress and press the raw products into the holes on the flat die. The raw materials get molded in these holes. When they are squeezed out, they end up being solid cyndrical tubes. Meanwhile, the solid friction in between roller as well as die warm up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They boost the adhesive pressure of materials.



The size of the pellets is established by the hole size of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cylinders, the slicer under the flat die reduced them right into certain size. You can readjust the setting of slicer to transform the size.




After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the function 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 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 turns and also the roller keep still. The later one has the press roller mounted on the main shaft. The roller revolves with the primary shaft, while the flat die keep still.



Roller-turned kind takes on a lot more reliable structure. It has larger ability and even more long lasting transmission. However Die-turned kind is extra little and also mobile, with reduced expense. Naturally, both of them have the ability to make top quality pellets.



Advantages and also weak point of flat die pellet machine

Apartment die pellet mill has simple framework. It is small, light and mobile. The expense is a lot less than ring die pellet equipment It is easy to run and also keep. site link can observe the pelletizing procedure and also fix any fault in time. So it is preferred with farmers, house users, and small fuel manufacturing plant.



The flat dies are putting on parts, you need to replace it routinely. However it can be made use of with both sides. You can transform it over when one side has actually worn. In this way you can expand their working life and also decrease expense.



On the other hand, the relocating distance are various in the internal and also outer side of roller, which create the slide of rollers and abrasion on the flat die. Currently, many flat die pellet equipment adopt conical roller to solve this trouble. TICO flat die pellet machine takes on conical roller as well as exceptional alloy steel in the flat die.

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



Exactly how does a ring die pellet equipment work?

Framework of ring die pellet equipment

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



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor connect with the transmission through a shaft coupling. The gearbox bring along the major shaft, and also the major shaft bring along the rollers. So the roller began to revolve inside the ring die.



When you feed resources right into the ring die pellet equipment through the receptacle, they are transferred to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw products intends to improve the adhesive pressure as well as developing rate.



After that, the processed resources will certainly be transmitted to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the internal side of the ring die. The roller press the raw materials right into the holes on the ring die. The heat and also high pressure cause physical and also chemical changes to the raw products.



When they are ejected from the ring die, they come to be strong round sticks. The sticks grow much longer, till they are cut by the slicer outside the ring die. After that the pellets fall down and also come out with the outlet.



Two types of ring die pellet machine

According to different positionings 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 up and down. When raw materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the vertical type, the ring die is put horizontally. The feed receptacle is right over the ring die, as well as the raw products falls under the ring die straight.



In the upright ring die pellet equipment, both the roller and ring die rotate. They create centrifugal pressure as well as disperse raw materials consistently. In the straight ring die pellet equipment, just the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet equipment.

Ring die pellet mill features high capability. 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 demand is under 800kg, you would certainly much better pick flat die pellet machine, or ring die pellet equipment is more suitable.



As a result of the high manufacturing, the power consumption each is reduced. The abrasion between roller and die is smaller. The operation as well as upkeep is very easy. The pellets are uniform in dimension.
