It seems you are asking about a 30kW Shredder Blower. This is a high-powered industrial component typically used in waste management, recycling, or material handling systems.
Here is a breakdown of what a 30kW Shredder Blower is, its specifications, common applications, and selection criteria.
What it is
A 30kW Shredder Blower is not a single machine, but usually one of two things:
- A combined Shredder & Blower unit: A machine that first shreds material (e.g., wood, paper, light plastics) and then uses an integrated centrifugal fan to blow the shredded material through ductwork to a collection point or storage silo.
- A standalone Heavy-Duty Blower: The fan/motor unit that is attached after a shredder to pneumatically convey the output material.
Key Specifications for a 30kW Unit
- Power: 30 kW (roughly 40 HP).
- Airflow: Typically between 5,000 to 12,000 m³/h depending on the impeller design and pressure.
- Pressure: Often a High Pressure (HP) or Medium Pressure fan.
Static Pressure range: 1,500 to 4,000 Pa (6 to 16 inches w.g.).
- Impeller: Usually radial or paddle-blade design to handle debris and dust without clogging.
- Material: Heavy-duty steel (often abrasion-resistant or lined) to withstand impact.
Common Applications
- Woodworking: Moving wood chips, shavings, and sawdust from a chipper or hammer mill.
- Paper & Cardboard Recycling: Shredding cardboard and blowing it into a containment area.
- Plastic Recycling: Chopping plastic bottles/containers and transporting the flake.
- Biomass Processing: Handling chipped branches, leaves, and green waste.
- Document Destruction (Industrial): Conveying shredded paper bails or loose material.
Safety & Selection Considerations
Because this is a 30kW system (high power), safety is critical.
- Explosion Protection: The most important factor. 30kW fans can generate a spark if metal hits the impeller.
- Look for: A Vent (explosion relief panel) and ductwork rated for your material (e.g., combustible dust standards like ATEX, NFPA 68).
- Material Handling Fan vs. Air Moving Fan:
- A standard HVAC fan will fail in minutes if hit by shredded wood.
- You need a Radial Paddle or Industrial Exhauster fan with a thick, reinforced wheel.
- Motor Type:
- Usually a TEFC (Totally Enclosed Fan Cooled) or TEAO (Totally Enclosed Air Over) motor.
- VFD (Variable Frequency Drive) compatible is common to control the material velocity.
Example of a System Component
If you are buying only the blower (not the shredder), you are likely looking for a 30kW Centrifugal Material Handling Fan.
Typical Model Numbers (examples, not exhaustive):
- American Fan: "CX" or "MSI" series
- Cincinnati Fan: "HP" or "PR" series
- European: "MZHR" or "RNL" series (often used for wood/pneumatic conveying)
Do you need the Shredder + Blower combo?
If you need the complete system, manufacturers often call this a "Grinder Blower" or "Shredder Conveyor". You would specify the material type and feed rate in kg/h.
To give you a more specific answer, please clarify:
- What material are you moving? (e.g., soft wood, hard plastic, cardboard, green waste?)
- Is the 30kW for the shredder motor, the blower motor, or the total combined power?
- What is the required transport distance? (e.g., 10m, 50m, 100m?)
