Working principle of wood crusher

The working principle of the wood comprehensive crusher is a complex and efficient process, mainly involving key steps such as feeding, cutting and crushing, screening and classification, and discharging. The following is a detailed explanation of the working principle:

Feed System

• Working principle: The raw wood is transported to the feed inlet of the crusher through a conveyor belt or other means. The design of the feeding system is directly related to the stable supply of wood, ensuring the normal progress of subsequent processes.
• Characteristics: Modern wood crushers often use self-priming feeding method, which sucks materials into the crushing chamber through the wind force of the induced draft fan. This method can more effectively control the input speed and quantity of materials.

Cutting and crushing system

• Core components: wood crushers are usually equipped with rotating cutting tools or hammers, which rotate at high speed under the drive of an electric motor.
• Crushing process: After entering the crushing chamber, the wood is subjected to cutting, impact, and high-speed airflow from the cutting tools. During this process, the wood is broken down into small pieces or particles. The crushing chamber may be divided into different stages such as coarse crushing, medium crushing, and fine crushing to improve the breadth of material crushing and the uniformity of finished particle size.
• Crushing principle: During the cutting and crushing process of the blade, the rotor generates high-speed airflow that rotates in the direction of the blade. The material accelerates in the airflow and repeatedly impacts and cuts through friction, while being subjected to various crushing effects, thus being effectively crushed.

Screening and classification system

• Working principle: The mixture of crushed wood chips and particles is separated through a screening system. This is usually accomplished through equipment such as analyzers and cyclone separators.
• Purpose: To collect fine particles that meet the specifications with the airflow into the powder collector, while coarse particles are returned to the crushing chamber for further crushing until satisfactory fineness is achieved.

Discharge system

• Working principle: After screening and classification, the sawdust and particles are promptly and effectively discharged from the crusher. The discharge system usually includes components such as conveying pipelines and discharge ports to ensure the smooth discharge of materials.
• Features: A well-designed discharge system can avoid the accumulation and blockage of wood particles, and improve the operational efficiency of the equipment.

control system

• Function: Modern wood crushers are typically equipped with advanced control systems for monitoring and regulating the operational status of the equipment.
• Function: including adjustment of motor power, control of tool system, and monitoring of overall operation. The intelligent control system makes operation more convenient and improves the stability and reliability of the equipment.

The discharge effect of wood crusher

In summary, the wood comprehensive crusher quickly and effectively processes raw wood into sawdust and pellets suitable for various purposes through key steps such as feeding, cutting and crushing, screening and classification, and discharging. The rationality and efficiency of its working principle make wood crushers play an important role in the wood processing and waste disposal industries.
