Certificated wood pellet mill equipment for sale comes in a variety of shapes in sizes, but despite of appearances, the essence of the machinery is the die which comes in two types: flat dies and ring dies. While mills with ring dies are most commonly used for commercial production, flat die mills are cheaper, hence more prevalent in residential and farm use. The flat die pellet press was first invented in the early 20th century to produce animal feed. It was only after technological advances in the die and rollers that the functionality of these machines was extended to process biomass materials such as sawdust, straw, corn stalks and grass.

Certificated Wood Pellet Mill Equipment for Sale has the following features:

1. The lubrication system for wood pellet mill adopts a tracing and inspection system controlled by a microcomputer. When the temperature of the bearings exceed normal temperatures, the microcomputer will start the auto-lubrication system for lubrication—thereby conveniently ensuring smooth functioning of the rollers.

2. The ring die and roller of the certificated wood pellet mill equipment for sale has been finely machined using alloyed steel. 

3. The drive gear is a precision-made transmission mechanism. The bearings are sourced from SKF in Sweden. The ring die uses a hoop fastening method which increases the speed of discharge in comparison with the previous bolt-fastening method.
