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



Ring die pellet mill has huge volume as well as high ability. It is suitable for factory use as well as large-scale production. Apartment die pellet mill is tiny as well as portable. It has reduced capacity, ideal for residence usage and also small-scale production. The cost of flat die pellet mill is a lot lower 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, an upper closet, a discharge outlet, a spindle box, transmission, 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 changed by a diesel engine, fuel engine, or a PTO port.



The core components: roller and also flat die

The pelletizing part of the flat die pellet equipment 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 flat die is made of remarkable alloy steel, whose hardness is 55-60 HRC.



There are lots of openings on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are the most common types. They realize the very best compression ratio with a lot of experiments, suitable for more than 30 type of materials.



The clearance in between the roller and also flat die is 0.1-0.3 mm. This is where the raw material layer types. There are 2 changing nuts on the side of the pellet mill, you can adjust the clearance to adjust to various materials.



Just how does a flat die pellet equipment work?

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



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



The rotating press types strong stress and also press the raw materials right into the holes on the flat die. The raw materials get molded in these openings. When they are squeezed out, they become strong cylinders. At the same time, the strong friction in between roller and die heat up the raw products to over 80 ° C, where the lignin and also fibers get soft. They enhance the glue pressure of materials.



The diameter of the pellets is determined by the opening dimension of the flat die, while the size is identified by the slicer under the flat die. When the biomass pellets come out in the shape of cyndrical tubes, 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 function of centrifugal force, the pellets are sent though the discharge outlet.



Two kinds of flat die pellet equipment

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



Roller-turned type embraces more efficient framework. It has bigger capacity and also even more durable transmission. Yet Die-turned kind is much more small and also portable, with lower expense. Of course, both of them have the ability to make top quality pellets.



Benefits and weak point of flat die pellet machine

Apartment die pellet mill has basic structure. It is small, light as well as mobile. The price is much lower than ring die pellet machine It is very easy to run and also preserve. You can observe the pelletizing process and also solve any type of mistake in time. So it is preferred with farmers, residence individuals, and tiny gas production plant.



The flat dies are putting on components, you require to replace it routinely. But it can be used with both sides. You can turn it over when one side has broken. In this way you can prolong their functioning life and also decrease cost.



On the other hand, the relocating range are various in the internal and also external side of roller, which trigger the slide of rollers as well as abrasion on the flat die. Presently, many flat die pellet equipment take on conical roller to resolve this trouble. TICO flat die pellet equipment adopts conical roller and premium alloy steel in the flat die.

Besides, the get in touch with location of roller as well as flat die is smaller sized than ring die pellet equipment, so the manufacturing capacity as well as developing rate is reduced.



Exactly how does a ring die pellet machine work?

Structure of ring die pellet machine

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 get in touch with the gearbox through a shaft coupling. The transmission bring along the primary shaft, and the primary shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed resources right into the ring die pellet machine through the hopper, they are transferred to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw products intends to boost the sticky pressure and also creating price.



Then, the refined 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 materials into the holes on the ring die. The high temperature as well as high pressure reason physical and also chemical modifications to the raw products.



When they are squeezed out from the ring die, they end up being solid cylindrical sticks. cattle feed pellet machine expand longer, till they are cut by the slicer outside the ring die. After that the pellets fall down and appear through the outlet.



Two types of ring die pellet equipment

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



In the straight type, the ring die is positioned vertically. When basic materials drop from the conditioner, they are fed into the ring die flat by a forced feeder. In the upright type, the ring die is put horizontally. The feed receptacle is right above the ring die, and the raw materials falls under the ring die directly.



In the vertical ring die pellet equipment, both the roller and also ring die turn. They form centrifugal force and also disperse resources uniformly. In the horizontal ring die pellet equipment, just the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages and weakness of ring die pellet equipment.

Ring die pellet mill features high ability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet machine, the capacity is from 100kg/h to 1t/t. So if you manufacturing demand is under 800kg, you 'd better select flat die pellet equipment, or ring die pellet machine is preferable.



Because of the high manufacturing, the power consumption each is reduced. The abrasion between roller and die is smaller sized. Richi machinery as well as maintenance is simple. The pellets are consistent in size.
