The optimal KW rating for an air blower connecting a plastic crusher to a silo ranges from 2.2kW to 15kW, with the exact value determined by your specific crushing capacity, material type, and conveying pipe length.
Recommended Power Reference by Working Condition
· Small-scale operations (100–300 kg/h, pipe length <10m): 2.2kW–5.5kW blower, suitable for low-volume PP/PE flake or small rigid plastic crushing lines
· Mid-scale standard lines (300–700 kg/h, pipe length 10–20m): 7.5kW–11kW blower, the most widely used configuration for general plastic recycling workshops
· High-capacity industrial lines (700–1500 kg/h, pipe length >20m): 11kW–15kW blower, designed for heavy-duty continuous conveying of large-volume crushed plastic scraps
Key Selection Factors
· Material type: Light, low-density plastic flakes (PP/PE films) require higher air volume than dense rigid plastic chunks, so you need to increase power by 20–30% for soft, fluffy materials
· Pipe layout: Every 5 meters of additional horizontal pipe or 3 meters of vertical lift adds 1–2 kW to the required blower power
· System configuration: If your setup includes a dust collector or cyclone separator, you need to reserve extra power margin to maintain stable material conveying
