Flat die pellet machine

Raw materials of flat die pellet machine

Different from ring die pellet machine, flat die pellet machine is suitable for small scale industry or just home use. With flat die pellet machines, the waste of household can be processed into biomass pellets, which can be used as biofuels instead of coal, natural gas etc.
Flat die pellet machine can process a wide range of raw materials. Such as rice husk, rice bran, wheat bran, maize straw, pineapple peel, peanut husk, canola straw, fresh grass, hay, bamboo, alfalfa, sawdust, wood shaving, wood powder, wood crapes, garbage waste paper and plastic, etc. If you have more than two kinds of raw materials you can also mix them together to obtain better pelletizing effect. If the size of raw materials is too big, a hammer mill is necessary.

Flat die pellet machine main components

The most important components of flat die pellet machine are dies and rollers, apart from these, a flat die pellet machine is composed of a hopper, transmission shaft, gear box, drive engine, slicer and outlet hopper.

Working principle of flat die pellet machine

First, feed the prepared raw materials into the hopper to distribute them on the flat die evenly. Then driven by different engines, like electric motor, diesel engine, gasoline and PTO, the main shaft will rotate the flat die and roller, with the extrusion between flat dies and rollers, the raw materials will be squeezed into the hole of flat dies and then be pressed. Now the heat of raw materials can up to over 80℃ due to the high friction between flat dies and rollers, which makes it easy to be molded, when they are out of the flat die holes, they will be the shape of cylinder because of the hole shape, and under the flat die, there is a rotating slicer, which can cut the cylinder pellets into the certain length, and at last fall out of the machine through outlet hopper.

Difference between R and D type flat die pellet machine

Generally speaking, there are two types of flat die pellet machine, D type and R type. For electric motor and diesel engine flat die pellet machine can be divided into these two types, but for gasoline and PTO flat die pellet machine, they usually adopt D type, rather than R type.
The difference between them lies in the transmission components and motion pattern. D type means a rotating die and a stationary roller, while R type refers to rotating roller and a stationary die. But their appearance is almost the same. Consider the production capacity, R type is a little higher than D type, homologous, the price of R type is a little higher than D type. Anyway, both types can produce excellent pellets. And D type is standard version, customers are also familiar with it, it’s popular with new comer. While R-type is suitable for customers who wants higher production capacity.
