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



Ring die pellet mill has huge quantity as well as high capacity. It appropriates for factory usage and also massive manufacturing. Apartment die pellet mill is tiny and portable. It has reduced capacity, appropriate for home use and also small-scale manufacturing. The price of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

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



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



The core parts: roller as well as flat die

The pelletizing part of the flat die pellet machine is a press roller as well as a flat die. They are installed in the top 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 and also flat die is made from exceptional alloy steel, whose firmness is 55-60 HRC.



There are lots of holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are one of the most common kinds. They realize the very best compression ratio with a lot of experiments, ideal for more than 30 sort of materials.



The clearance in 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 change the clearance to adjust to various materials.



How does a flat die pellet machine work?


When you feed basic materials right into the pellet machine through 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 electrical motor runs and bring along the main shaft with the gearbox. Journalism roller is mounted on the major shaft, so it rotates around the main shaft. Meanwhile, hemp pelletizer revolve around the roller shaft.



The rotating press kinds solid stress and also press the raw materials right into the holes on the flat die. The raw materials get molded in these holes. When they are ejected, they come to be strong cyndrical tubes. On richi pellet machine , the strong rubbing in between roller and die warm up the raw materials to over 80 ° C, where the lignin as well as fibers get soft. They increase the sticky force of materials.



The size of the pellets is established by the hole size of the flat die, while the size is established 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 specific length. You can readjust 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 function of centrifugal force, the pellets are sent out though the discharge outlet.



Two kinds of flat die pellet machine

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



Roller-turned kind takes on extra reliable framework. It has bigger ability as well as more durable gearbox. However Die-turned kind is more little and also mobile, with reduced price. Of course, both of them are able to make top notch pellets.



Advantages and weak point of flat die pellet equipment

Apartment die pellet mill has simple framework. It is tiny, light and also mobile. The expense is a lot lower than ring die pellet machine It is very easy to run and also keep. You can observe the pelletizing procedure and also fix any fault in time. So it is preferred with farmers, home individuals, as well as little fuel production plant.




The flat dies are using components, you need to replace it consistently. However it can be utilized with both sides. You can transform it over when one side has worn. By doing this you can prolong their functioning life and reduce expense.



On the other hand, the moving range are various in the internal as well as outer side of roller, which create the slide of rollers as well as abrasion on the flat die. Currently, numerous flat die pellet equipment embrace tapered roller to fix this problem. TICO flat die pellet equipment takes on conical roller and exceptional alloy steel in the flat die.

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



Just how does a ring die pellet machine work?

Framework of ring die pellet equipment

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



The ring die pellet equipment is driven by a direct-connected motor. The motor connect with the gearbox through a shaft combining. The transmission bring along the major shaft, as well as the major 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 via the hopper, they are sent to the conditioner, where the raw products are combined with vapor or butter. The conditioning of the raw products aims to boost the adhesive pressure and creating rate.



After that, the processed raw materials will certainly be transmitted to the pelletizing cupboard. 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 high pressure reason physical as well as chemical modifications to the raw products.



When they are ejected from the ring die, they become strong round sticks. The sticks expand much longer, till they are reduced by the slicer outside the ring die. After that the pellets drop and come out via the outlet.



2 types of ring die pellet equipment

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



In the horizontal type, the ring die is positioned vertically. When resources drop from the conditioner, they are fed into the ring die horizontally by a forced feeder. In the upright kind, the ring die is placed flat. The feed receptacle is right over the ring die, and the raw materials falls under the ring die straight.



In the upright ring die pellet machine, both the roller as well as ring die rotate. They form centrifugal pressure as well as distribute basic materials evenly. In the horizontal ring die pellet machine, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Benefits and also weakness of ring die pellet equipment.

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



As a result of the high production, the power usage per unit is low. The abrasion between roller and also die is smaller sized. The procedure as well as maintenance is very easy. The pellets are consistent in size.
