Raw Material Crushing Equipment for Mushroom Substrate Preparation
Prepare wood, corn cobs, stalks, straw, and other raw materials for consistent mushroom substrate mixing with crushing and cutting equipment designed for different production requirements.
Crushing • Cutting • Screening
What Production Stage Does Raw Material Crushing Equipment Support?
Raw material crushing is an important first-stage process in mushroom substrate preparation. Before materials are mixed with water and other substrate ingredients, they often need to be reduced to a suitable particle size.

What Types of Mushroom Raw Material Crushers Are Available?
Different raw materials require different crushing structures, capacity ranges, and particle-size control. The equipment range includes three main configurations.
What Production Stage Does Raw Material Crushing Equipment Support?
Raw material crushing is an important first-stage process in mushroom substrate preparation. Before materials are mixed with water and other substrate ingredients, they often need to be reduced to a suitable particle size.
Sawdust Crusher
Designed for wood and mixed wood. The knife-disc and hammer structure supports one-pass crushing with replaceable screens.
- Power: 15–28 kW
- Capacity: 700–1,800 kg/h
- Screen: 8–20 mm
- Structure: Knife-disc + hammer
Corn Cob Crusher
Designed for corn cobs, corn stalks, and soybean straw. The hammer structure uses interchangeable screens.
- Power: 7.5–22 kW
- Capacity: 600–1,500 kg/h
- Screen: 6–20 mm
- Structure: Hammer
Straw Crusher
Designed for wheat straw, rice straw, and corn stalks. Its knife-wheel structure focuses on cutting and fiber loosening.
- Power: 1.5–4 kW
- Capacity: 400–1,500 kg/h
- Function: Cutting and fiber loosening
- Length: Adjustable
Which Mushroom Cultivation Applications Can These Machines Support?
The processed raw material can become a component of growing substrate for different edible fungi, depending on the cultivation recipe and substrate formulation.
For oyster mushroom cultivation, sawdust, corn cobs, corn stalks, and straw can be processed before mixing. For shiitake production, wood-based substrate preparation is particularly important.
King oyster mushrooms and other cultivated edible fungi can also use prepared substrate materials according to their individual cultivation formulas.

Suitable Production Scales
- Small mushroom farms
- Laboratory-scale substrate preparation
- Commercial mushroom factories
- Automated substrate production lines
Smaller crushers can be integrated into a simple feeding-and-mixing workflow, while higher-capacity models can be connected with conveyors, substrate mixers, bagging machines, and subsequent sterilization equipment.
Beyond mushroom cultivation, some models can also process agricultural residues for applications such as organic fertilizer production, agricultural waste recycling, biomass processing, and livestock-related material preparation, depending on the material and machine configuration.
How Should You Choose the Right Crushing Equipment?
The main factors are raw material, required particle size, processing capacity, available power supply, and production scale.
For Wood Logs or Branches
Choose a Sawdust Crusher when direct crushing and screening are required. Replaceable screens are available from 8–20 mm.
Oyster Mushroom
Choose a Corn Cob Crusher for corn cobs, corn stalks, and soybean straw. Screen options range from 6–20 mm.
For Fibrous Straw
Choose a Straw Crusher for wheat straw, rice straw, and similar fibrous agricultural residues. Cutting length is adjustable.
When selecting a model, also consider feeding method, conveyor configuration, electrical supply, required output, and downstream mixer capacity. Matching these factors helps avoid production bottlenecks.
Connect Crushing Equipment with Your Substrate Production Line
Raw material crushing can operate as an independent preparation step or as part of a complete mushroom substrate production line.
For larger production systems, crushing equipment can be planned together with feeding systems, conveyors, substrate mixing, bag filling, sterilization, and other downstream processes.
Typical Process Flow
Equipment capacity, feeding method, conveyor configuration, electrical supply, and downstream mixer capacity should be matched to the intended production flow.The main factors are raw material, required particle size, processing capacity, available power supply, and production scale.
Can Raw Material Crushing Equipment Be Customized?
Yes. Equipment configuration can be selected according to the customer’s raw material, required output, particle-size requirements, and production process.
- Raw material type
- Target processing capacity
- Required particle size
- Applicable screen opening
- Motor configuration
- Power conditions
