The working principle of a wood crushing machine

---

• Dual crushing technology
• By combining blade cutting with high-speed airflow impact, the material is accelerated and repeatedly impacted within the airflow, achieving efficient crushing and fine material sorting, thereby significantly improving the crushing rate.
• Multi-stage crushing process
• The crushing chamber adopts a fine crushing principle device, which employs three-stage processing: coarse crushing, fine crushing, and centrifugal re-crushing, to ensure uniform particle size of the finished product and strong fine crushing capability.
• Compact structural design
• Host composition: It consists of three parts: rotor, upper body, and lower body, integrating chip cutting device, crushing device, and fan.
• Auxiliary system: equipped with analyzers, powder collectors, and dust collectors to form a continuous operation system, eliminating traditional screening processes and simplifying processes.
• Drive mode: single motor drive, flexible power configuration, supports motor or diesel engine, suitable for fixed and mobile operation scenarios.

Product characteristics and advantages of sawdust crusher

• Efficient and energy-saving
• The crushing efficiency is increased by more than 50% compared to traditional equipment, with low unit energy consumption and high output (models covering 400-4000kg/h).
• Compact structure, small footprint, suitable for small and medium-sized enterprises as well as individual businesses.
• Stable and durable
• The blade adopts a combination of Type 7 blade, Type 1 blade and centrifugal blade, with strong wear resistance and long service life.
• The fan impeller has undergone dynamic balance testing and runs smoothly with low noise and reduced vibration.
• Easy to operate
• Self suction feeding design ensures safe production and avoids damage to equipment caused by foreign objects such as metal blocks.
• Integrated dust removal system effectively reduces dust and improves the working environment.
• Cost-effective
• Low investment cost, controllable processing cost, suitable for large-scale production and individualized processing needs.
• The finished product has high quality and can be directly used for high-end board manufacturing or biomass energy production.

The core functions and uses of wood chippers

---

The slicer can process branches and twigs with a diameter of 1-30 cm, as well as fibrous materials such as bamboo, thatch, corn stalks, sorghum stalks, etc., achieving multifunctional use.

• Agriculture and Environmental Protection
• Soil improvement: Wood chips can enhance soil water permeability and retention, promoting plant growth.
• Organic fertilizer: Organic fertilizer is generated through composting and applied in agriculture and horticulture.
• Feed ingredients: Some wood chips can be used as animal feed additives after treatment.
• Industrial production application
• Edible mushroom culture medium: Crushed sawdust is an ideal substrate for mushroom cultivation.
• Board manufacturing: used as raw materials for particleboard, sawdust board, high-density board, and medium fiber board.
• Paper and pulp: Provide fiber raw materials to support pulp production.
• Biomass energy: converting sawdust into wood pellets, charcoal, or biomass fuel for power generation, heating, and industrial energy.

Your next step should be to define your project’s specifications. Once you have a clear idea, the best course of action is to speak with an experienced equipment manufacturer. We can provide technical advice to ensure your choice is the right one.

Key Factors to Consider When Selecting a Wood Crusher

---

To select the right wood crusher, you need to match the machine’s capabilities—specifically its inlet size, power, and screen—to your raw material and your desired final product. We design our machines to be versatile, but making the right choice upfront is key to efficiency.

1. Raw Material Size and Type

What are you crushing? The maximum diameter of the logs or the width of the boards you plan to process will determine the required size of the machine’s feed inlet. Our popular 420 Model Wood Crusher, for example, is excellent for branches and logs up to 15 cm in diameter. For larger logs or bulky waste like pallets, you might need a larger machine like a Comprehensive Crusher.

2. Required Output Capacity (Tons/Hour)

How much sawdust do you need to produce per day or week? Our models are rated in tons per hour. It is vital to choose a machine that can comfortably meet your production targets without running at 100% capacity all day. For example, the 420 model has a capacity of 0.8-1 ton/hour, making it perfect for small to medium-sized operations.

3. Desired Final Sawdust Size

What is the end use for your material? The required fineness of the sawdust will determine the screen mesh size you need.

Fine Wood Flour: May require a very fine screen (2-4 mm) or a two-step grinding process.
We provide a range of screens and can advise on the best one for your application.

Animal Bedding: Usually requires a coarser particle (5-8 mm screen).

Biomass Pellets: Requires a finer particle (3-5 mm screen).

Summary and Recommendations

A wood crusher is a highly versatile and profitable machine that solves the core problem of low-value wood waste. By transforming logs, branches, and offcuts into uniform sawdust, it provides the essential raw material for profitable industries like mushroom farming, biomass energy, and animal husbandry.

The key to a successful investment is choosing the right model based on your raw materials, capacity needs, and operational setup (stationary vs. mobile). By carefully considering these factors, you can select a machine that will serve your business reliably for years to come.

Your Next Step:
Assess your current wood waste stream. Determine your required daily output of sawdust. Then, contact our team of experts. We will help you configure the perfect wood crusher solution for your business.
