‌Determining the optimal shot blasting speed and shot blasting amount of the shot blasting machine requires consideration of multiple factors, including workpiece material, surface condition, shape and size, production efficiency requirements, etc. ‌

Shot blasting speed ‌Workpiece material‌: For metal workpieces, the shot blasting speed is generally between 60-80 m/s; for non-metallic workpieces, the shot blasting speed should be between 40-60 m/s‌. ‌Surface condition‌: Workpieces with severe surface rust or thick oxide scale require higher shot blasting speeds to ensure the cleaning effect‌. ‌Shape and size‌: Workpieces with complex shapes or more grooves and dead corners require higher shot blasting speeds to ensure that each part can be effectively processed‌. ‌Production efficiency requirements‌: In large-scale production, higher shot blasting speeds are required to meet production schedules; small-scale production can appropriately reduce the shot blasting speed‌. ‌ Shot blasting amount

‌Workpiece size‌: The shot blasting amount for small workpieces should be between 30-50 kg/min, for medium-sized workpieces between 50-80 kg/min, and for large workpieces between 80-120 kg/min‌.

‌Surface condition‌: Workpieces with many surface impurities require a larger shot blasting amount to ensure the cleaning effect‌.

‌Production efficiency requirements‌: Large-scale production requires a larger shot blasting amount to improve production efficiency; small-scale production can appropriately reduce the shot blasting amount‌.

Adjustment method

‌Monitoring and adjustment‌: When using the shot blasting machine, it is necessary to monitor the shot blasting amount and speed in real time to ensure that they are within the specified range. If the treatment effect is found to be poor, it should be adjusted in time‌.

‌Flexible adjustment according to specific circumstances‌: According to the specific situation of the workpiece and production needs, the shot blasting speed and shot blasting amount can be flexibly adjusted to achieve the best surface treatment effect‌.
