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



Ring die pellet mill has huge quantity and high ability. It is suitable for factory usage and also large production. Flat die pellet mill is small as well as portable. manure pelletizer has lower ability, ideal for home use and small-scale production. The rate of flat die pellet mill is much less than ring die pellet mill



Structure 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, gear box, a transmission shaft, an electrical control closet, an electrical motor, a engine base, and 4 wheels, and so on.



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





The core parts: roller as well as flat die

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



There are lots of holes on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm as well as 10mm are one of the most common types. They understand the most effective compression proportion with a large number of experiments, suitable for more than 30 kinds of products.



The clearance between the roller and flat die is 0.1-0.3 mm. This is where the raw material layer kinds. There are 2 adjusting 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 job?

When you feed resources into the pellet equipment through the receptacle, they fall on the flat die as well as spread over it under the feature of roller.



When you begin the pellet machine, the electric motor runs as well as bring along the primary shaft via the transmission. Journalism roller is mounted on the main shaft, so it turns around the main shaft. On the other hand, the rollers revolve around the roller shaft.



The rotating press kinds strong stress as well as press the raw materials into the holes on the flat die. The raw materials obtain built in these openings. When they are squeezed out, they become solid cyndrical tubes. On the other hand, the strong rubbing between roller as well as die heat up the raw products to over 80 ° C, where the lignin and fibers get soft. They raise the adhesive force of products.



The size of the pellets is figured out by the hole dimension 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 cut them right into certain length. You can adjust the placement of slicer to transform 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 electrical outlet.



Two types of flat die pellet equipment

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



Roller-turned type adopts much more efficient framework. It has larger capacity and also even more resilient gearbox. However he has a good point -turned type is a lot more little and portable, with reduced cost. Naturally, both of them have the ability to make high-grade pellets.



Advantages and also weak point of flat die pellet machine

Flat die pellet mill has basic structure. It is small, light and portable. The expense is a lot less than ring die pellet machine It is easy to run as well as keep. You can observe the pelletizing process and fix any type of fault in time. So it is popular with farmers, home customers, and also small gas production plant.



The flat dies are putting on components, you require to replace it frequently. However it can be made use of with both sides. You can turn it over when one side has actually broken. This way you can prolong their working life and also minimize cost.



On the other hand, the relocating range are different in the inner and external side of roller, which trigger the slide of rollers and also abrasion on the flat die. Currently, several flat die pellet equipment embrace conical roller to resolve this trouble. TICO flat die pellet equipment adopts conical roller and also exceptional alloy steel in the flat die.

Besides, the call area of roller as well as flat die is smaller than ring die pellet equipment, so the manufacturing capacity and also creating price is lower.



Exactly how does a ring die pellet equipment job?

Framework of ring die pellet machine

A ring die pellet machine is made up of a screw feeder, conditioner, roller as well as ring die, discharge port, electrical motor, gearbox, pedestal.



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 transmission 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 equipment through the hopper, they are transferred to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw products aims to improve the adhesive force and also forming rate.



After that, the processed resources will certainly be sent to the pelletizing closet. Under the centrifugal pressure, they are distributed 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 as well as chemical adjustments to the raw materials.



When they are ejected from the ring die, they become strong cylindrical sticks. The sticks expand much longer, until they are reduced by the slicer outside the ring die. Then the pellets fall down and also come out via the electrical outlet.



Two kinds of ring die pellet machine

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



In the horizontal kind, the ring die is placed vertically. When resources fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright kind, the ring die is put horizontally. The feed receptacle is right above the ring die, as well as the raw materials falls into the ring die straight.



In the upright ring die pellet equipment, both the roller as well as ring die rotate. They develop centrifugal force and also disperse resources uniformly. In the horizontal ring die pellet machine, just the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet machine.

Ring die pellet mill features high capacity. The manufacturing per hr is from 800kg to 20t. When it comes to flat die pellet machine, the capability is from 100kg/h to 1t/t. So if you production demand is under 800kg, you would certainly much better pick flat die pellet equipment, or ring die pellet equipment is better.



Due to the high manufacturing, the power intake each is low. The abrasion in between roller as well as die is smaller. The operation as well as upkeep is easy. The pellets are uniform in dimension.
