Ring die pellet mill has big volume and high capability. It appropriates for manufacturing facility use and also large manufacturing.richi machineryis tiny and mobile. It has reduced ability, suitable for home usage and also small-scale manufacturing. The rate of flat die pellet mill is a lot less than ring die pellet mill
Structure of flat die pellet mill.
From top to bottom, a flat die pellet mill is composed of a feed receptacle, an upper closet, a discharge electrical outlet, a spindle box, transmission, a transmission shaft, an electric control closet, an electrical motor, a engine base, as well as 4 wheels, etc.
The electrical motor can be replaced by a diesel motor, fuel engine, or a PTO connector.
The core components: roller and flat die
The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are installed in the upper closet. There are 2-4 rollers set up on the 2 ends of the roller shaft. The rollers have grooves on the surface area. The roller and also flat die is made from premium alloy steel, whose solidity is 55-60 HRC.
There are lots of holes on the flat die, whose size is from 2.5 mm to 10mm, and 6mm, 8mm and 10mm are the most typical types. They realize the best 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 kinds. There are 2 readjusting nuts on the side of the pellet mill, you can adjust the clearance to adjust to different materials.
How does a flat die pellet machine job?
When you feed resources 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 electrical motor runs and also bring along the major shaft with the transmission. Journalism roller is installed on the primary shaft, so it turns around the major shaft. At the same time, the rollers revolve around the roller shaft.
The revolving press types strong pressure 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 end up being strong cylinders. Meanwhile, the strong rubbing between roller and also die heat up the raw materials to over 80 C, where the lignin and fibers get soft. They raise the glue pressure of products.
The diameter of the pellets is determined by the opening size of the flat die, while the length is identified 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 right into specific length. You can change the placement of slicer to change 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 out though the discharge outlet.
2 types of flat die pellet equipment
Apartment die pellet mill can be classified into roller-turned type as well as die-turned kind. The former one has its flat die set up on the main shaft. When the machine functions, the flat die rotates and also the roller keep still. The later one has journalism roller mounted on the major shaft. The roller revolves with the major shaft, while the flat die maintain still.
Roller-turned type takes on a lot more reliable framework. It has larger ability and also even more sturdy transmission. Howevermanual feed pellet machine -turned kind is more little and mobile, with lower expense. Certainly, both of them have the ability to make top notch pellets.
Advantages and weakness of flat die pellet equipment
Flat die pellet mill has simple structure. It is tiny, light and mobile. The cost is much less than ring die pellet equipment It is very easy to operate and also preserve. You can observe the pelletizing process and solve any kind of mistake in time. So it is popular with farmers, home users, and little fuel manufacturing plant.
The flat dies are putting on parts, you require to change it routinely. However it can be made use of with both sides. You can transform it over when one side has worn. This way you can extend their functioning life and reduce cost.
On the other hand, the moving distance are different in the inner as well as outer side of roller, which trigger the slide of rollers and abrasion on the flat die. Presently, lots of flat die pellet machine embrace conical roller to resolve this trouble. TICO flat die pellet machine adopts conical roller and also 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 machine, so the manufacturing ability and also creating rate is lower.
Just how does a ring die pellet machine job?
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, electrical motor, gearbox, stand.
The ring die pellet machine is driven by a direct-connected motor. The electric motor connect with the gearbox through a shaft coupling. The transmission bring along the primary shaft, as well as the main shaft bring along the rollers. So the roller began to rotate inside the ring die.
When you feed raw materials into the ring die pellet equipment via the receptacle, they are transmitted to the conditioner, where the raw materials are mixed with vapor or butter. The conditioning of the raw products intends to enhance the glue pressure and creating rate.
Then, the refined raw materials will certainly be transferred to the pelletizing closet. Under the centrifugal force, they are distributed on the internal side of the ring die. The roller press the raw products right into the holes on the ring die. The high temperature as well as high pressure reason physical and also chemical changes to the raw materials.
When they are squeezed out from the ring die, they become solid cylindrical sticks. The sticks expand much longer, till they are reduced by the slicer outside the ring die. Then the pellets drop and also come out with the electrical outlet.
2 sorts of ring die pellet equipment
According to different placements of the ring die, there are vertical ring die pellet machine as well as straight ring die pellet equipment.
In the straight kind, the ring die is positioned vertically. When raw 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 placed flat. The feed receptacle is right above the ring die, and also the raw products falls under the ring die directly.
In the upright ring die pellet machine, both the roller as well as ring die rotate. They form centrifugal force and distribute 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.
Benefits and weakness of ring die pellet machine.
Ring die pellet mill includes high ability. The manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet machine, the ability is from 100kg/h to 1t/t. So if you production requirement is under 800kg, you 'd better pick flat die pellet equipment, 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. The procedure and upkeep is easy. The pellets are uniform in size.
