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



Ring die pellet mill has huge quantity and high ability. It is suitable for manufacturing facility usage and massive production. Apartment die pellet mill is tiny as well as portable. It has lower ability, appropriate for home usage and small production. The rate of flat die pellet mill is much 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, a top cupboard, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electrical control closet, an electric motor, a engine base, as well as 4 wheels, and so on.



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



The core parts: roller and also 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 closet. There are 2-4 rollers set up 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 solidity 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 and also 10mm are the most usual kinds. They recognize the best compression ratio with a multitude of experiments, ideal for more 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 product layer forms. There are 2 adjusting nuts on the side of the pellet mill, you can change the clearance to adjust to various materials.



Just how does a flat die pellet equipment work?

When you feed resources right into the pellet machine with the hopper, they fall on the flat die and spread over it under the function of roller.



When you start the pellet machine, the electric motor runs and bring along the primary shaft via the transmission. The press roller is set up on the main shaft, so it revolves around the major shaft. At the same time, the rollers turn around the roller shaft.



The rotating press kinds solid stress and press the raw products into the holes on the flat die. The raw materials obtain built in these holes. When they are ejected, they become strong cyndrical tubes. Meanwhile, the solid friction in between roller as well as die heat up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They enhance the adhesive pressure of materials.



The size of the pellets is established by the opening size of the flat die, while the length is figured out 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 position of slicer to change the length.



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 out though the discharge outlet.



2 kinds of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned type as well as die-turned kind. The previous one has its flat die set up on the main shaft. When the machine functions, the flat die revolves and also the roller maintain still. The later one has the press roller installed on the primary shaft. The roller revolves with the major shaft, while the flat die maintain still.



Roller-turned type embraces extra reliable framework. It has bigger capability and also more resilient gearbox. Yet Die-turned kind is more small and also portable, with reduced cost. Of course, both of them are able to make top notch pellets.



Benefits and also weak point of flat die pellet machine

Flat die pellet mill has easy framework. https://www.debwan.com/blogs/426819/Unpredictable-current-of-the-biomass-pellet-making-machine is little, light and mobile. The price is much lower than ring die pellet equipment It is easy to operate as well as maintain. You can observe the pelletizing process and also fix any mistake in time. So it is prominent with farmers, home customers, as well as little gas manufacturing plant.



The flat dies are wearing components, you need to replace it on a regular basis. But find out this here can be made use of with both sides. You can turn it over when one side has actually broken. In this way you can extend their working life and also lower 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 also abrasion on the flat die. Currently, lots of flat die pellet machine adopt conical roller to resolve this issue. TICO flat die pellet equipment embraces conical roller and superior alloy steel in the flat die.

Besides, the contact area of roller and flat die is smaller than ring die pellet machine, so the production capability and also developing rate is reduced.



How does a ring die pellet equipment job?

Structure of ring die pellet machine

A ring die pellet equipment is composed of a screw feeder, conditioner, roller and also ring die, discharge port, electrical motor, transmission, pedestal.



The ring die pellet machine is driven by a direct-connected motor. The electric motor get in touch with the gearbox with a shaft coupling. The gearbox bring along the main shaft, as well as the main shaft bring along the rollers. So the roller started to rotate inside the ring die.



When you feed basic materials into the ring die pellet machine with the receptacle, they are transferred to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw products intends to enhance the glue force and also developing price.



After that, the refined resources will be transmitted to the pelletizing closet. Under the centrifugal force, 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 reason physical and chemical adjustments to the raw materials.



When they are ejected from the ring die, they become solid round sticks. The sticks expand longer, up until they are cut by the slicer outside the ring die. After that the pellets drop and appear via the outlet.



2 types of ring die pellet machine

According to different placements of the ring die, there are vertical ring die pellet equipment as well as horizontal ring die pellet equipment.



In the horizontal kind, the ring die is put up and down. When basic materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the upright type, the ring die is positioned flat. The feed receptacle is right above the ring die, as well as the raw products falls into the ring die directly.



In the upright ring die pellet machine, both the roller as well as ring die turn. They form centrifugal pressure and disperse resources consistently. In the straight ring die pellet machine, just the ring die rotates. The raw materials are distributed in the ring die by the screw feeder.



Advantages 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 ability is from 100kg/h to 1t/t. So if you production need is under 800kg, you 'd better choose flat die pellet machine, or ring die pellet machine is preferable.



As a result of the high manufacturing, the power intake each is low. The abrasion in between roller and die is smaller sized. The procedure and maintenance is simple. The pellets are uniform in dimension.
