Biomass pellet machine Introduction

A biomass pellet machine is a specialized mechanical device used for processing biomass materials such as wood chips, straw, corn stalks, etc., into pelletized products. Its working principle involves processing biomass materials through heating, compression, and other processes to form pellets of specific sizes and shapes. These pellets are commonly used as a form of biomass energy, such as biomass pellet fuel. Biomass pellet machines have wide applications in the field of renewable energy and can be used for home heating, industrial heating, animal feed, and more.

Classification of biomass pellet machines

The biomass pellet machine is a device that processes materials such as paulownia, cypress, poplar, fruitwood, agricultural crop straw, bamboo shavings, etc., by crushing them into sawdust-like bran and then processing them into biomass fuel.

Due to variations in raw materials used in different regions, the biomass pellet machine is known by different names such as wood pellet machine, straw pellet machine, sawdust pellet machine, wood chip pellet machine, bamboo pellet machine, fuel pellet machine, rice husk pellet machine, etc. It is also referred to as a pelletizer or pellet maker. Despite the differences in terminology, they all refer to the same type of machine.

Based on the type of die used, it can be further categorized into flat die pellet machine and ring die pellet machine. The ring die pellet machine can be further classified into vertical ring die pellet machine and horizontal ring die pellet machine.

According to the working principle of the feed pellet machine, it can be classified into die roller pellet machine and screw extrusion pellet machine. According to the purpose of the feed pellet machine, it can be classified into single-feed pellet machine and mixed-feed pellet machine.
