Notes

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



Ring die pellet mill has large quantity and high ability. It appropriates for factory use and also massive production. Apartment die pellet mill is little and mobile. It has lower capacity, ideal for home use and also small manufacturing. The price 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 receptacle, an upper cupboard, a discharge electrical outlet, a pin box, transmission, a transmission shaft, an electric control cupboard, an electrical motor, a engine base, and 4 wheels, etc.



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



The core components: roller and flat die

The pelletizing part of the flat die pellet machine is a press roller and a flat die. They are mounted 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. The roller as well as flat die is constructed from premium alloy steel, whose solidity is 55-60 HRC.



There are many openings on the flat die, whose diameter is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are one of the most usual kinds. They understand the most effective compression proportion with a lot of experiments, suitable for greater than 30 kinds of products.



The clearance 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 readjust the clearance to adapt to different products.



Exactly how does a flat die pellet machine work?

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



When you start the pellet equipment, the electrical motor runs and also bring along the major shaft through the gearbox. The press roller is set up on the primary shaft, so it turns around the major shaft. On the other hand, the rollers turn around the roller shaft.



The turning press types solid stress and also press the raw materials right into the holes on the flat die. The raw materials get built in these holes. When they are ejected, they become solid cyndrical tubes. On the other hand, the strong rubbing between roller as well as die warm up the raw products to over 80 ° C, where the lignin and fibers obtain soft. They boost the sticky force of materials.



The size of the pellets is determined by the opening dimension of the flat die, while the length is determined by the slicer under the flat die. When the biomass pellets appear in the shape of cylinders, the slicer under the flat die reduced them into particular length. You can readjust the setting of slicer to alter the size.



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 out though the discharge electrical outlet.



2 types of flat die pellet equipment

Flat die pellet mill can be classified right into roller-turned kind and die-turned kind. The former one has its flat die mounted on the major shaft. When pellet machine for sale , 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 major shaft, while the flat die keep still.



Roller-turned kind embraces more efficient structure. It has bigger ability and even more long lasting gearbox. But Die-turned kind is more tiny and also mobile, with lower expense. Naturally, both of them have the ability to make premium pellets.



Benefits and also weakness of flat die pellet machine

Apartment die pellet mill has basic framework. It is little, light and portable. The price is a lot less than ring die pellet equipment It is very easy to operate and also maintain. You can observe the pelletizing process and address any type of mistake in time. So it is popular with farmers, home users, as well as little fuel manufacturing plant.



The flat dies are wearing components, you need to change it consistently. But it can be utilized with both sides. You can turn it over when one side has worn out. By doing this you can extend their working life and lower cost.



On the other hand, the relocating distance are different in the internal and outer side of roller, which cause the slide of rollers and also abrasion on the flat die. Currently, lots of flat die pellet machine embrace conical roller to solve this problem. TICO flat die pellet machine embraces tapered roller and also premium alloy steel in the flat die.

Besides, the call location of roller and flat die is smaller sized than ring die pellet machine, so the production ability and creating rate is lower.




How does a ring die pellet machine job?

Framework of ring die pellet machine

A ring die pellet equipment is made up of a screw feeder, conditioner, roller as well as ring die, release 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 transmission bring along the main shaft, as well as the main shaft bring along the rollers. So the roller began to turn inside the ring die.



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



After that, the refined resources will be transferred to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw materials right into the holes on the ring die. The high temperature as well as high pressure reason physical and chemical adjustments to the raw products.



When they are ejected from the ring die, they become strong cylindrical sticks. The sticks grow 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 types of ring die pellet machine

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



In the straight kind, the ring die is placed up and down. 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 placed horizontally. The feed hopper is right over the ring die, and the raw products falls under the ring die directly.



In the vertical ring die pellet equipment, both the roller and ring die rotate. They develop centrifugal pressure and distribute basic materials consistently. In the straight ring die pellet machine, only 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 machine.

Ring die pellet mill includes high capacity. The manufacturing per hr is from 800kg to 20t. As for flat die pellet machine, the capacity is from 100kg/h to 1t/t. So if you production requirement is under 800kg, you 'd much better select flat die pellet equipment, or ring die pellet equipment is preferable.



As a result of the high manufacturing, the power usage per unit is low. pellet machine for sale between roller as well as die is smaller. The operation as well as upkeep is simple. The pellets are uniform in size.
