Adjustment of blast wheel speed The rotational speed of the blast wheel is a key factor influencing the abrasive feed rate. Adjusting the blast wheel speed changes both the ejection velocity and the throughput of steel abrasive. Generally, raising the blast wheel speed increases abrasive throughput. However, excessively high speed accelerates abrasive wear and impairs blasting quality. Accordingly, the blast wheel speed must be balanced based on actual working conditions.
Adjustment of abrasive particle size and feed flow Abrasive particle size and feed flow rate are also critical variables that govern blasting throughput. In most cases, larger abrasive grains deliver higher blasting volume, and a higher abrasive feed flow also raises throughput. Regulating particle size and feed flow enables precise control over abrasive delivery. It should be noted that such adjustments must match the workpiece material and surface condition to prevent excessive wear or workpiece damage.
Optimization of workpiece loading method and layout Workpiece loading mode and arrangement have an impact on effective abrasive utilization and actual blasting volume. Rational loading schemes and layout improve abrasive utilization efficiency and raise effective blasting output. For instance, multi-layer loading and stepped layout ensure uniform abrasive impact across all workpiece surfaces.
