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



Ring die pellet mill has big volume and high ability. It is suitable for manufacturing facility usage and large production. Flat die pellet mill is little and also portable. It has lower capacity, suitable for house usage and small-scale manufacturing. The rate of flat die pellet mill is a lot less than ring die pellet mill



Framework of flat die pellet mill.

From top to bottom, a flat die pellet mill is made up of a feed receptacle, a top cupboard, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electric control cupboard, an electric motor, a engine base, and also 4 wheels, and so on.



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



The core parts: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are installed in the top cabinet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and also flat die is made of premium alloy steel, whose firmness is 55-60 HRC.



There are numerous openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm and also 10mm are one of the most usual types. They understand the most effective compression ratio with a multitude of experiments, ideal for greater than 30 kinds of products.



The clearance in 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 changing nuts on the side of the pellet mill, you can adjust the clearance to adapt to different materials.



How does a flat die pellet machine work?

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



When you start the pellet equipment, the electric motor runs and bring along the main shaft via the transmission. Journalism roller is set up on the major shaft, so it turns around the primary shaft. On the other hand, the rollers turn around the roller shaft.



The rotating press forms solid stress and also press the raw materials into the holes on the flat die. The raw products get formed in these openings. When they are squeezed out, they become strong cyndrical tubes. At the same time, the solid 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 raise the adhesive pressure of products.



The diameter 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 form of cylinders, the slicer under the flat die cut them right into particular size. You can adjust the setting of slicer to transform 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 though the discharge electrical outlet.



Two sorts of flat die pellet machine


Apartment die pellet mill can be classified right into roller-turned type and die-turned type. The former one has its flat die installed on the primary shaft. When the equipment works, the flat die rotates and the roller maintain still. The later one has journalism roller installed on the main shaft. The roller revolves with the primary shaft, while the flat die maintain still.



Roller-turned type adopts extra efficient structure. It has larger capacity and even more long lasting gearbox. But Die-turned type is much more small and also mobile, with reduced price. Of course, both of them have the ability to make premium pellets.



Advantages and also weakness of flat die pellet machine

Apartment die pellet mill has simple framework. It is tiny, light as well as mobile. The expense is much less than ring die pellet equipment It is easy to operate as well as keep. You can observe the pelletizing process and also fix any type of mistake in time. So it is popular with farmers, house users, as well as little fuel manufacturing plant.



The flat dies are wearing components, you require to change it on a regular basis. However it can be made use of with both sides. You can transform it over when one side has worn. By doing this you can prolong their working life and lower expense.




On the other hand, the relocating range are different in the inner as well as outer side of roller, which cause the slide of rollers as well as abrasion on the flat die. Presently, lots of flat die pellet machine embrace conical roller to resolve this issue. TICO flat die pellet machine embraces tapered roller as well as exceptional alloy steel in the flat die.

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



Exactly how does a ring die pellet machine work?

Structure 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, electrical motor, transmission, stand.



The ring die pellet equipment is driven by a direct-connected motor. The motor get in touch with the transmission with a shaft combining. The transmission bring along the primary shaft, and the primary shaft bring along the rollers. So plastic pelletizer started to turn inside the ring die.



When you feed basic materials right into the ring die pellet equipment via the receptacle, they are transferred to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials aims to boost the glue force and also creating price.



Then, the processed raw materials will certainly be transferred to the pelletizing cupboard. Under the centrifugal force, they are distributed on the inner side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature and also high pressure reason physical and chemical modifications to the raw products.



When they are ejected from the ring die, they come to be solid round sticks. The sticks grow longer, till they are cut by the slicer outside the ring die. Then the pellets drop and appear through the outlet.



Two sorts of ring die pellet equipment

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



In the horizontal type, the ring die is put vertically. When basic 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 placed horizontally. The feed receptacle is right over the ring die, and also the raw materials comes under the ring die straight.



In the vertical ring die pellet equipment, both the roller and also ring die revolve. They create centrifugal pressure and distribute basic materials uniformly. 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.



Advantages and also weak point of ring die pellet machine.

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



Because of the high manufacturing, the power intake per unit is reduced. The abrasion in between roller and die is smaller sized. wood pellet machine as well as maintenance is simple. The pellets are consistent in size.
