Removal Mechanism
Compressed air bursts remove identified contaminants from a fast moving stream of raw cotton or synthetic fiber. The pneumatic air ejection system acts as the final gatekeeper in foreign matter detection hardware. Individual nozzles activate with millisecond precision to target specific unwanted particles without wasting compliant fiber.
Mechanical Operation
Timing logic coordinates the delay between the sensor signal and the physical blast to ensure high removal accuracy. Pneumatic air ejection typically occurs after an optical array spots polypropylene or colored twine mixed in the white cotton bale. Multiple banks of valves work simultaneously to handle high volume throughput during the opening and cleaning process at the beginning of the spinning line.
The pressure must be set correctly to prevent fiber entanglement or excessive loss of good raw material.
Process Waste
Yield remains tied to the narrowness of the air pulse and the precision of the targeted zone. Poorly calibrated pneumatic air ejection results in heavy secondary waste containers that require more manual sorting before reprocessing.
Sorting Stability
Reliability depends on a dry, clean air supply to prevent valve stiction or nozzle clogging. Every shift requires a check of the pneumatic air ejection sequence to ensure contaminant targets are reliably hit.
