Ring die pellet mill has huge volume as well as high capability. It is suitable for factory use and large manufacturing. Apartment die pellet mill is small and mobile. It has lower capacity, ideal for residence use as well as small manufacturing. 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 composed of a feed hopper, a top cupboard, a discharge outlet, a pin box, gear box, a transmission shaft, an electrical control cabinet, an electric motor, a engine base, and also 4 wheels, etc.
The electric motor can be replaced by a diesel motor, gasoline engine, or a PTO adapter.
The core parts: roller and flat die
The pelletizing part of the flat die pellet equipment is a press roller as well as a flat die. They are set up in the top cupboard. 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 constructed from premium alloy steel, whose solidity is 55-60 HRC.
There are many openings on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm and 10mm are one of the most usual kinds. They understand the best compression ratio with a lot of experiments, ideal for greater than 30 type of products.
The clearance between the roller and 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 adapt to various materials.
Just how does a flat die pellet equipment job?
When you feed raw materials into the pellet machine via the hopper, they fall on the flat die and also spread over it under the feature of roller.
When you start the pellet machine, the electrical motor runs and bring along the primary shaft with the transmission. Journalism roller is installed on the main shaft, so it turns around the major shaft. On the other hand, the rollers turn around the roller shaft.
The turning press types strong stress and press the raw products right into the holes on the flat die. The raw materials obtain built in these holes. When they are squeezed out, they end up being solid cylinders. On the other hand, the strong rubbing between roller and die warm up the raw materials to over 80 ° C, where the lignin as well as fibers obtain soft. They raise the glue pressure of materials.
The size of the pellets is established by the hole dimension of the flat die, while the size is figured out by the slicer under the flat die. When the biomass pellets appear in the form of cyndrical tubes, the slicer under the flat die cut them right into certain size. You can change 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 feature of centrifugal force, the pellets are sent though the discharge outlet.
2 sorts of flat die pellet equipment
Flat die pellet mill can be classified right into roller-turned kind and also die-turned kind. The previous one has its flat die set up on the primary shaft. When the machine functions, the flat die turns and also the roller keep still. The later one has the press roller set up on the primary shaft. The roller revolves with the main shaft, while the flat die keep still.
Roller-turned type adopts much more effective structure. It has bigger capacity and even more long lasting gearbox. Yet Die-turned kind is more small and mobile, with reduced price. Of course, both of them have the ability to make high-quality pellets.
Advantages and weak point of flat die pellet machine
Apartment die pellet mill has easy framework. It is small, light and also mobile. pelletizer die is a lot lower than ring die pellet machine It is very easy to operate and also maintain. You can observe the pelletizing procedure as well as solve any fault in time. So cpm pellet press is preferred with farmers, home users, and little gas manufacturing plant.
The flat dies are using components, you need to change it on a regular basis. However it can be made use of with both sides. You can transform it over when one side has broken. In this way you can expand their functioning life and also lower expense.
On the other hand, the moving distance are different in the inner and external side of roller, which create the slide of rollers and also abrasion on the flat die. Presently, lots of flat die pellet equipment embrace tapered roller to solve this problem. TICO flat die pellet machine takes on conical roller and also exceptional alloy steel in the flat die.

Besides, the get in touch with area of roller and flat die is smaller than ring die pellet machine, so the production capability and also forming rate is reduced.
How does a ring die pellet equipment job?
Framework of ring die pellet equipment
A ring die pellet machine is made up of a screw feeder, conditioner, roller and also ring die, discharge port, electrical motor, transmission, pedestal.
The ring die pellet machine is driven by a direct-connected motor. The motor connect with the gearbox with a shaft coupling. The gearbox bring along the major shaft, as well as the primary shaft bring along the rollers. So the roller started to rotate inside the ring die.
When you feed basic materials into the ring die pellet machine through the receptacle, they are transferred to the conditioner, where the raw products are blended with vapor or butter. The conditioning of the raw materials aims to improve the glue force and also creating rate.
Then, the processed basic materials will be transmitted to the pelletizing cabinet. Under the centrifugal force, they are dispersed on the inner side of the ring die. used pellet machine for sale press the raw products into the holes on the ring die. The heat and also high pressure reason physical and also chemical modifications to the raw materials.
When they are ejected from the ring die, they come to be strong cylindrical sticks. The sticks grow much longer, up until they are cut by the slicer outside the ring die. Then the pellets fall down and appear via the outlet.
2 kinds of ring die pellet machine
According to various placements of the ring die, there are vertical ring die pellet machine as well as straight ring die pellet equipment.
In the horizontal kind, the ring die is placed vertically. When raw materials drop from the conditioner, they are fed right into the ring die flat by a forced feeder. In the vertical kind, the ring die is placed horizontally. The feed hopper is right over the ring die, and the raw materials falls into the ring die directly.
In the vertical ring die pellet machine, both the roller as well as ring die revolve. They develop centrifugal force and disperse raw materials uniformly. In the straight ring die pellet machine, only the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.
Benefits and also weakness of ring die pellet machine.
Ring die pellet mill features 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 manufacturing need is under 800kg, you would certainly better choose flat die pellet machine, or ring die pellet equipment is better.
Due to the high manufacturing, the power intake per unit is low. The abrasion between roller and die is smaller sized. The procedure and upkeep is simple. The pellets are uniform in size.
