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



Ring die pellet mill has huge quantity and high ability. wood pellet crusher is suitable for factory usage and large manufacturing. Flat die pellet mill is little and mobile. It has lower ability, ideal for home usage and small production. The rate of flat die pellet mill is a lot lower than ring die pellet mill



Framework of flat die pellet mill.

Inside out, a flat die pellet mill is made up of a feed hopper, an upper cupboard, a discharge outlet, a pin box, transmission, a transmission shaft, an electrical control cabinet, an electrical motor, a engine base, and also 4 wheels, and so on.



The electric motor can be replaced by a diesel engine, gasoline 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 mounted in the upper closet. There are 2-4 rollers installed on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller and flat die is made from exceptional alloy steel, whose solidity is 55-60 HRC.



There are numerous openings on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm as well as 10mm are the most usual kinds. They realize the very best compression proportion with a large number of experiments, suitable for greater than 30 type 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 types. There are 2 adjusting nuts on the side of the pellet mill, you can change the clearance to adjust to various products.



How does a flat die pellet equipment job?

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




When you start the pellet machine, the electric motor runs and bring along the main shaft through the gearbox. The press roller is mounted on the main shaft, so it revolves around the major shaft. At the same time, the rollers rotate around the roller shaft.



The revolving press types strong stress and also press the raw products into the holes on the flat die. The raw materials get built in these openings. When they are ejected, they come to be solid cylinders. Meanwhile, the solid friction between roller and die heat up the raw products to over 80 ° C, where the lignin as well as fibers get soft. They enhance the adhesive force of materials.



The diameter of the pellets is figured out by the opening dimension of the flat die, while the length is established by the slicer under the flat die. When the biomass pellets appear in the form of cylinders, the slicer under the flat die reduced them into particular size. You can readjust the placement 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.



2 types of flat die pellet machine

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



Roller-turned kind adopts much more reliable structure. It has larger ability and more resilient transmission. Yet Die-turned type is much more tiny and also mobile, with lower price. Obviously, both of them have the ability to make high-grade pellets.



Advantages and weak point of flat die pellet machine

Apartment die pellet mill has simple structure. flat die pellet mill for sale is small, light and also mobile. The cost is much less than ring die pellet machine It is very easy to operate as well as preserve. You can observe the pelletizing procedure as well as fix any type of fault in time. So it is prominent with farmers, home customers, as well as little gas production plant.



The flat dies are putting on parts, you require to change it frequently. Yet it can be made use of with both sides. You can transform it over when one side has worn. By doing this you can expand their working life and decrease price.



On the other hand, the relocating distance are various in the inner and external side of roller, which cause the slide of rollers and abrasion on the flat die. Presently, many flat die pellet equipment adopt tapered roller to fix this trouble. TICO flat die pellet machine adopts tapered roller as well as superior alloy steel in the flat die.

Besides, the get in touch with location of roller and also flat die is smaller sized than ring die pellet machine, so the production capability and also forming price is reduced.



Exactly how does a ring die pellet machine work?

Framework of ring die pellet equipment

A ring die pellet equipment is made up of a screw feeder, conditioner, roller and ring die, discharge port, electric motor, transmission, pedestal.



The ring die pellet equipment is driven by a direct-connected motor. The motor get in touch with the gearbox via a shaft coupling. The gearbox bring along the main shaft, and also the major shaft bring along the rollers. So the roller started to turn inside the ring die.



When you feed raw materials right into the ring die pellet equipment via the receptacle, they are transmitted to the conditioner, where the raw products are mixed with vapor or butter. The conditioning of the raw materials aims to enhance the glue force and forming rate.



Then, the refined basic materials will certainly be sent to the pelletizing closet. Under grass pellet mill for sale , 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 changes to the raw materials.



When they are ejected from the ring die, they end up being strong round sticks. The sticks expand longer, until they are reduced by the slicer outside the ring die. Then the pellets fall down and appear with the outlet.



2 types of ring die pellet equipment

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



In the straight type, the ring die is placed vertically. When basic materials fall down from the conditioner, they are fed right into the ring die flat by a forced feeder. In the upright type, the ring die is placed flat. The feed hopper is right above the ring die, and the raw materials falls into the ring die directly.



In the upright ring die pellet machine, both the roller and also ring die rotate. They create centrifugal pressure and disperse raw materials evenly. In the horizontal ring die pellet machine, just the ring die rotates. The raw products are distributed in the ring die by the screw feeder.



Advantages and also weak point of ring die pellet machine.

Ring die pellet mill includes high ability. The production per hr 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 need is under 800kg, you would certainly much better choose flat die pellet machine, or ring die pellet machine is more suitable.



As a result of the high production, the power consumption per unit is reduced. The abrasion in between roller as well as die is smaller sized. The procedure as well as maintenance is easy. The pellets are uniform in size.
