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



Ring die pellet mill has large volume and high capacity. It appropriates for manufacturing facility usage and large-scale manufacturing. Apartment die pellet mill is tiny as well as mobile. It has reduced capacity, suitable for residence usage and also small-scale manufacturing. The rate of flat die pellet mill is a lot lower than ring die pellet mill




Structure of flat die pellet mill.

Inside out, a flat die pellet mill is composed of a feed receptacle, an upper cabinet, a discharge electrical outlet, a spindle box, gear box, a transmission shaft, an electrical control closet, an electric motor, a engine base, and 4 wheels, etc.



The electric motor can be changed by a diesel engine, fuel engine, or a PTO connector.



The core components: roller as well as flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are mounted in the upper closet. 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 flat die is constructed from premium alloy steel, whose firmness is 55-60 HRC.



There are many holes on the flat die, whose size is from 2.5 mm to 10mm, and also 6mm, 8mm and also 10mm are the most typical kinds. They understand the very best compression ratio with a lot of experiments, appropriate for more than 30 type of materials.



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



Exactly how does a flat die pellet machine job?

When you feed resources right into the pellet machine through 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 primary shaft, so it revolves around the primary shaft. At the same time, the rollers revolve around the roller shaft.



The rotating press forms solid pressure as well as press the raw materials into the holes on the flat die. The raw materials get formed in these holes. When they are squeezed out, they end up being strong cylinders. On the other hand, the solid rubbing in between roller and also die heat up the raw products to over 80 ° C, where the lignin and also fibers obtain soft. They boost the sticky force of materials.



The diameter of the pellets is figured out by the opening size of the flat die, while the length is established by the slicer under the flat die. When the biomass pellets come out in the form of cylinders, the slicer under the flat die reduced them into certain size. You can adjust the setting of slicer to transform the length.



After being reduced by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal force, the pellets are sent out though the discharge electrical outlet.



Two sorts of flat die pellet equipment

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



Roller-turned type adopts a lot more effective structure. It has larger ability and even more resilient transmission. But Die-turned kind is much more tiny as well as mobile, with lower cost. Obviously, hop pellet mill for sale of them are able to make top quality pellets.



Benefits and also weak point of flat die pellet equipment

Apartment die pellet mill has simple framework. It is small, light and also mobile. The cost is a lot less than ring die pellet machine It is very easy to run as well as keep. You can observe the pelletizing process and solve any kind of fault in time. So it is popular with farmers, residence individuals, and also small gas manufacturing plant.



The flat dies are putting on parts, you require to replace it regularly. Yet it can be made use of with both sides. You can transform it over when one side has broken. This way you can expand their working life and decrease price.



On the other hand, the moving distance are various in the inner as well as external side of roller, which trigger the slide of rollers as well as abrasion on the flat die. Currently, animal feed pellet machine of flat die pellet equipment take on tapered roller to address this problem. TICO flat die pellet equipment embraces conical roller and remarkable alloy steel in the flat die. Click the switch listed below to obtain a quick quote!



Besides, the call location of roller and also flat die is smaller sized than ring die pellet machine, so the production capacity and also forming price is lower.




Exactly how does a ring die pellet equipment job?

Framework of ring die pellet equipment

A ring die pellet equipment is composed of a screw feeder, conditioner, roller and also ring die, discharge port, electric motor, gearbox, stand.



The ring die pellet machine is driven by a direct-connected motor. The motor connect with the transmission via a shaft coupling. The transmission bring along the main shaft, and also the primary shaft bring along the rollers. So the roller began to rotate inside the ring die.



When you feed resources into the ring die pellet equipment via the receptacle, they are sent to the conditioner, where the raw materials are combined with vapor or butter. The conditioning of the raw materials aims to enhance the sticky pressure and also forming price.



Then, the refined raw materials will be transferred to the pelletizing closet. Under the centrifugal pressure, they are dispersed on the internal side of the ring die. The roller press the raw materials into the holes on the ring die. The high temperature and also high pressure cause physical and chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they end up being solid cylindrical sticks. The sticks grow longer, till they are reduced by the slicer outside the ring die. After that the pellets fall down as well as appear with the outlet.



Two kinds of ring die pellet equipment

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



In the straight type, the ring die is put up and down. When basic materials 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 put horizontally. The feed receptacle is right over the ring die, as well as the raw products falls into the ring die straight.



In the upright ring die pellet equipment, both the roller and ring die turn. They form centrifugal pressure and distribute basic materials consistently. In the straight ring die pellet equipment, only the ring die rotates. The raw products are dispersed in the ring die by the screw feeder.



Advantages and weak point of ring die pellet equipment.

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



As a result of the high manufacturing, the power consumption per unit is low. The abrasion in between roller and die is smaller sized. The operation as well as upkeep is simple. The pellets are consistent in dimension.
