Wood Chip Grinder – Chipping & Grinding Machine

The Wood Chip Grinder is a hammer-type wood grinding machine designed for processing pine, poplar, bamboo, palm fruit, and various biomass materials into fine wood chips and sawdust. With a power range of 15–55 kW and capacity from 200 to 2000 kg/h, this versatile machine combines chipping and grinding functions in one compact unit. It is widely used in edible fungi cultivation (mushroom substrate preparation), particleboard and fiberboard production, sawdust board manufacturing, and biomass fuel preparation. The wood chip grinder offers an ideal solution for small to medium-sized enterprises and individual operators seeking efficient, cost-effective wood processing equipment.

Product Features

1. Dual-Function Chipping & Grinding – The wood chip grinder consists of a chip cutting device, grinding device, and fan. Wood chips are reduced to small size after cutting, then sent directly to the grinding device without drying. Finished products are discharged by the fan. The entire equipment is driven by a single electric motor with simple structure, compact layout, stable operation, low energy consumption, high output, and low processing cost.

2. Adjustable Hammer & Sieve Gap – The machine features adjustable gap between hammer and sieve plate, enabling both coarse grinding and fine grinding. This one-machine dual-function capability provides flexibility for different material size requirements.

3. Static Balance Calibrated Rotor – The rotor has passed static balance calibration, ensuring low noise, smooth operation, increased productivity, and extended service life.

4. U-Type Double Crushing Chamber – The innovative U-type double crushing chamber structure effectively changes the material's running track, increasing output and improving grinding efficiency.

5. Safety Control System – The equipment is installed with a comprehensive safety control system. The machine cannot be started if any component is not installed or properly closed, preventing unsafe operation and ensuring production safety.

6. Premium Components – Equipped with Siemens motor and SKF bearings for reliable performance and long service life.

7. Robust Construction – Made of Q235 material with plate thickness of 10mm and 8mm, lining thickness 15mm, base plate thickness 20mm, 12mm and 10mm, and rotor plate thickness 8mm for maximum durability.

FAQ

Q1: What is the finished product fineness? Can it be adjusted?

The fineness is adjustable. By changing the sieve screen aperture and adjusting the clearance between hammers and sieve plate, users can switch between coarse grinding and fine grinding to meet different application requirements.

Q2: Can the machine process wet materials? Is pre-drying required?

Yes, wet materials can be processed directly. No pre-drying is required, which saves energy and simplifies the production workflow.

Q3: What are the main wear parts? How often should they be replaced?

The main wear parts are hammers, sieve screens, and chipping blades. Replacement cycles depend on material type and processing volume. Regular inspection is recommended to ensure consistent performance.

Q4: What safety features does the machine have?

The machine is equipped with a safety control system that prevents startup if any component is not properly installed or closed, effectively avoiding unsafe operation.

Q5: How do I choose the right model?

Selection depends on raw material type, required daily capacity, desired particle size, and on-site power conditions. Please refer to the technical parameter table or consult the supplier for professional guidance.
