This is a very specific piece of industrial equipment. A "55kW Shredder Blower" typically refers to a high-power centrifugal fan or industrial blower integrated into a heavy-duty shredding or material handling system.

Here is a breakdown of what this equipment is, its typical applications, and key specifications.

What is a 55kW Shredder Blower?

A 55kW (approx. 73.7 HP) blower is a large, powerful unit. In the context of a shredder, it is not the shredding motor itself, but rather the pneumatic conveying system that moves material after it has been shredded.

• Function: It creates a high-velocity airstream (suction or pressure) to transport shredded material (e.g., paper, plastic, wood, textiles, light metals) through ducts to a collection point, baler, storage silo, or further processing equipment.
• Power: 55kW indicates a heavy-duty system capable of moving bulk material over long distances (e.g., 50-200+ meters or 150-600+ feet) or vertically.

Key Components & Features

1. Motor: 55kW (Usually a 3-phase induction motor, 380V-690V, IP55 or higher for dust protection).
2. Impeller/Fan Wheel:
   • High-Wear Design: Often made from abrasion-resistant materials (e.g., Hardox steel) or with replaceable wear plates.
   • Type: Typically an open paddle wheel or radial blade design to handle large, sharp, or sticky particles without clogging.
3. Housing: Heavy-duty welded steel with access hatches for maintenance.
4. Speed: Direct drive (e.g., 1500-3000 RPM depending on motor poles) or belt-driven.
5. Airflow & Pressure: (Approximate ranges for a 55kW unit)
   • Airflow (Capacity): 15,000 – 30,000 m³/h (8,800 – 17,600 CFM)
   • Static Pressure: Typically 2500 – 4500 Pa (10 – 18 inches w.g.)

Typical Applications

• Waste Management: Pneumatic conveying of shredded MSW (Municipal Solid Waste), RDF (Refuse Derived Fuel), or bulky waste.
• Wood Processing: Moving wood chips, sawdust, and shredder residue from pallet or demolition wood shredders.
• Paper & Document Shredding: High-security shredding operations where material is sucked away from the shredder to a remote baler.
• Plastics Recycling: Conveying shredded plastic flakes or regrind.
• Metal Recycling: Transporting shredded light scrap (e.g., shredder fluff from ELV/End-of-Life Vehicles) or non-ferrous metals.

Important Considerations for Selection

1. Material Density & Size: A blower for light plastic film is different from one for heavy wood chunks. You must match the impeller design and housing size to the material.
2. Separation System: Is there a cyclone, rotary airlock, or filter system downstream? A blower with direct material handling (material passes through the fan) requires a heavy-duty, wear-resistant wheel. Alternatively, a clean air blower (using a rotary airlock feeder) extends fan life.
3. Duct Layout: Total length, number of bends, and vertical lift drastically affect the required pressure and thus the selected motor power (in this case, 55kW is already chosen, so the pressure rating of this specific blower must be verified).
4. Noise & Vibration: A 55kW blower is very loud. It requires a robust foundation, vibration isolation (spring mounts), and often silencers or sound enclosures.
5. Electrical Requirements: Starting method (Star-Delta, VFD, Soft Starter), breaker size, and cable sizing for a 55kW motor.

Summary Answer for a Technical Inquiry:

"A 55kW Shredder Blower is a heavy-duty centrifugal fan used for pneumatic conveying of shredded material. It is designed for high-volume, high-pressure applications such as waste, wood, or paper recycling. The unit will feature a wear-resistant open impeller and a 55kW motor, capable of moving approximately 15,000-30,000 m³/h of air at pressures up to 4000+ Pa. Key considerations for implementation include line velocity (typically 20-25 m/s for solids), dust filtering, and noise control."

If you are looking to buy or specify one, you will need to provide the following data:

• Material type (e.g., wood chips, plastic film, confidential paper).
• Bulk density (kg/m³).
• Conveying distance (horizontal and vertical).
• Required throughput (e.g., tons/hour).
• Duct diameter and layout preferences.
