screw extrusion pellet machine

screw extrusion pellet machine Introduction

A screw extrusion pellet machine is a machine device that compresses and extrudes raw materials into pellet shapes using a screw mechanism. It typically consists of components such as a feeding system, compression screw, die, and discharge outlet. During operation, the raw materials are conveyed into the pellet machine, then compressed and extruded by the screw inside the die to form pellets. This type of pellet machine is suitable for processing various forms of materials, including biomass materials such as sawdust, straw, corn stalks, rice straw, as well as coal powder. Screw extrusion pellet machines are characterized by easy operation, high production efficiency, and high pellet forming rate, and are widely used in the biomass energy field and pellet production processes.

The structure of screw extruder pellet machine

Feeding system

Responsible for conveying the raw materials into the machine. It typically includes a hopper or conveyor belt.

Screw mechanism

This is the core component of the machine responsible for compressing and extruding the raw materials into pellets. It consists of a rotating screw housed within a barrel.

Die and roller assembly

The die determines the shape and size of the pellets, while the roller applies pressure to the raw materials as they pass through the die.

Cutting mechanism

Used to cut the extruded pellets into the desired length. It may consist of rotating blades or knives.

Cooling system

Cools down the pellets after they are formed to improve hardness and durability.

Discharge chute

Where the finished pellets are discharged from the machine.

Control panel

Controls various parameters of the machine such as speed, temperature, and pressure.

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.
