Wood Sawdust Crusher for Mushroom Substrate Production

Wood Sawdust Crusher is a professional raw material processing machine designed for edible mushroom substrate preparation. It crushes wood logs, branches and other woody materials into uniform sawdust particles through a high-speed blade and hammer crushing system, helping mushroom farms efficiently produce suitable substrate materials while reducing manual labor and improving cultivation consistency.

The machine solves the important first-stage problem in mushroom cultivation: converting large wood materials into suitable sawdust for substrate mixing and mushroom bag production. With three models available, it can meet different production requirements from small mushroom farms to commercial substrate processing workshops.

Wood Sawdust Crusher Working Principle

The machine converts woody materials into sawdust through feeding, cutting, crushing, screening and discharge.
01

Raw Material Feeding

Wood logs, branches or wood pieces enter the crushing chamber.

02

Cutting & Crushing

Rotating hammers and blades rapidly impact and cut the material.

03

Screening

Replaceable screens control sawdust particle size from 8–20 mm.

04

Sawdust Discharge

Processed sawdust exits for substrate mixing and further processing.

Wood Feeding → Crushing → Screening → Sawdust Collection

Suitable Raw Materials and Mushroom Applications

Applicable Raw Materials

The Wood Sawdust Crusher is mainly used for woody biomass processing, including:
Hardwood logs
Softwood materials
Tree branches
Wood chips
Forestry waste
Agricultural wood waste

The processed sawdust has uniform particle size and good moisture absorption characteristics, making it suitable for mushroom substrate production.

Suitable Mushroom Cultivation

Shiitake Mushroom Cultivation
Shiitake mushroom commonly uses wood-based substrates. Freshly processed sawdust provides suitable structure and nutrition for mycelium growth.
Oyster Mushroom Cultivation
Oyster mushroom farms often use sawdust mixed with corn cob, straw and other agricultural materials. Uniform sawdust improves substrate mixing quality.
Wood Ear Mushroom Cultivation
Wood ear mushroom bag cultivation requires stable substrate structure. Proper sawdust particle size helps maintain moisture and air permeability.
Other Cultivated Mushrooms
Suitable for:
King oyster mushroom
Reishi mushroom
Other wood-loving fungi

Capacity / Production Scale

Different models are designed for different production scales.
production Scales Model Capacity Power Suitable for
Small and Medium Mushroom Farms CRXH700A 700 kg/h 15 kW Small mushroom farms, Family cultivation workshops, Small substrate preparation rooms
Commercial Mushroom Production CRXH1000A 1,000 kg/h 18 kW Suitable for medium-scale farms requiring continuous sawdust production
Industrial Mushroom Substrate Factories CRXH1800A 1,800 kg/h 28 kW Large mushroom factories, Commercial substrate suppliers

Integration With Mushroom Production Line

The Wood Sawdust Crusher is usually the first processing machine in a mushroom substrate production system.

Upstream Equipment

Wood collection system
Log cutting machine
Wood storage system

Downstream Equipment

After crushing, sawdust can be transferred to:
Mushroom Substrate Mixer
Mix sawdust with corn cob, straw, water and nutritional additives.
Mushroom Bagging Machine
Automatically fill mixed substrate into mushroom bags.
Mushroom Sterilization Equipment
Sterilize filled bags before inoculation.
Complete Production Flow:

Wood Material → Wood Sawdust Crusher → Mushroom Substrate Mixer → Mushroom Bagging Machine → Sterilizer → Mushroom Growing Room

Automation Options

The standard machine uses manual feeding operation. For higher production efficiency, it can be integrated with:

Feeding conveyors
Storage systems
Dust collection systems
Automatic substrate production lines

Automation level can be customized according to customer production capacity.
