The price of the pellet machine is related to the structure and internal design of the pellet machine. First, let’s understand the price of the pellet machine equipment.
The working principle of sawdust pellet machine

When the wood pellet machine is working, the material rotates into the material cavity through the feeding port, and through the action of centrifugal force, the material is continuously attached to the inner wall of the die in circular motion, forming a uniform annular material layer, which is counteracted by the pressure roller. The stuck material is continuously rotated and extruded to force it into the ring die hole to be formed, and continuously extruded outward. .

Design of sawdust pellet machine

The ring die of the pellet mill is generally made of high-quality alloy steel, chrome steel and carburized stainless steel. The production is to first calcine or roll the steel as a whole into a blank, then drill after turning, and then carry out nitriding treatment. The surface hardness reaches 53-49HRC, and the inner wall of the die hole reaches a roughness of 1.6.

The shape of the die hole includes straight hole, stepped hole, outer cone hole, inner micro hole, etc. The size of the die hole is determined according to the diameter of the die hole.

Apertures can generally be divided into 2 categories, one is small inside and large outside, which is used for die holes with a diameter of less than 10 mm; the other is large inside and small outside, this is when the diameter of die holes is greater than 10 mm.

Different pellets are required, and the molds of Kunming sawdust pellet machine are different, and the compression ratio is different. Commonly used die thicknesses are in the range of 32-127 mm.
