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



Ring die pellet mill has big volume and also high capability. It is suitable for manufacturing facility use and also large-scale production. Apartment die pellet mill is little as well as mobile. It has reduced ability, suitable for home use and small manufacturing. The cost 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 hopper, an upper closet, a discharge outlet, a spindle box, gear box, a transmission shaft, an electrical control cabinet, an electric motor, a engine base, as well as 4 wheels, and so on.



The electrical motor can be changed by a diesel engine, fuel engine, or a PTO adapter.



The core parts: roller and 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 from premium alloy steel, whose hardness is 55-60 HRC.



There are many openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm as well as 10mm are one of the most common types. They understand the best compression ratio with a lot of experiments, ideal for greater than 30 type of products.



The clearance in 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 adjust the clearance to adapt to different products.



Just how does a flat die pellet machine work?

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



When you begin the pellet equipment, the electric motor runs as well as bring along the primary shaft with the transmission. Journalism roller is installed on the primary shaft, so it turns around the main shaft. At the same time, the rollers turn around the roller shaft.



The rotating press kinds strong pressure and press the raw materials into the holes on the flat die. The raw products obtain built in these holes. When they are squeezed out, they end up being strong cylinders. On richi pellet mill , the strong friction between roller as well as die warm up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They increase the glue pressure of products.



The size of the pellets is determined by the opening dimension of the flat die, while the length is determined by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die reduced them right into specific length. You can readjust the position of slicer to alter the length.



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 electrical outlet.



Two kinds of flat die pellet machine

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



Roller-turned kind adopts more effective structure. It has larger capacity and also more long lasting gearbox. Yet Die-turned type is much more tiny and also mobile, with reduced expense. Naturally, both of them are able to make premium pellets.



Benefits and weak point of flat die pellet equipment

Flat die pellet mill has basic structure. It is little, light as well as mobile. The cost is much lower than ring die pellet equipment It is very easy to operate as well as preserve. You can observe the pelletizing process and solve any type of fault in time. So it is preferred with farmers, residence customers, and small fuel production plant.



The flat dies are using parts, you need to change it frequently. Yet it can be utilized with both sides. You can transform it over when one side has worn. In this way you can expand their functioning life and also minimize expense.



On the other hand, the relocating distance are different in the internal and also outer side of roller, which trigger the slide of rollers and also abrasion on the flat die. Presently, many flat die pellet equipment embrace conical roller to resolve this problem. TICO flat die pellet machine embraces tapered roller and remarkable alloy steel in the flat die.

Besides, the call location of roller and also flat die is smaller sized than ring die pellet equipment, so the production ability as well as creating price is reduced.



How does a ring die pellet machine job?

Framework of ring die pellet machine

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



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



When you feed basic materials right into the ring die pellet equipment with the hopper, they are sent to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw materials aims to enhance the adhesive pressure and forming price.



Then, the processed basic materials will be sent to the pelletizing closet. Under the centrifugal pressure, 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 heat and high pressure cause physical and chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they become strong cylindrical sticks. The sticks grow much longer, till they are reduced by the slicer outside the ring die. After that the pellets fall down as well as appear with the outlet.



Two kinds of ring die pellet equipment

According to various positionings of the ring die, there are vertical ring die pellet machine and also straight ring die pellet machine.



In the horizontal type, the ring die is put vertically. When resources drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the vertical type, the ring die is positioned horizontally. The feed hopper is right above the ring die, and also the raw products comes under the ring die straight.



In the vertical ring die pellet machine, both the roller and ring die revolve. richi pellet develop centrifugal force and disperse basic materials uniformly. 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.



Advantages and weak point of ring die pellet machine.


Ring die pellet mill includes high capacity. The production 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 manufacturing requirement is under 800kg, you would certainly better pick flat die pellet machine, or ring die pellet equipment is better.



As a result of the high production, the power intake per unit is reduced. The abrasion in between roller and die is smaller. The procedure and also maintenance is easy. The pellets are consistent in dimension.
