Floor shot blasting machine Operational principle This equipment use mechanical way to shot steel shot or grains on work piece surface with high speed and stated angle.Then shot material and impurities will be recovered separately for recycling use through cleaner air flow.It equips with dust collector to dust-free and pollution-free construction.It noy only improve the efficiency but also protect environment. Working condition: Irregularity degree <20mm,no seeper and comparatively dry, gradient<25° Ambient temperature:-20°C ~60°C,steel plate surface temperature is greater than dew point 3°C. Humidity:a,steel plate surface temperature comparative humidity ≤90% Concrete shot blast comparative humidity ≤95% Altitude:0-3000m.It must’t operate in rain and snow weather. Efficiency: Cement surface:200-400m2/hour Steel plate:cleaness grade is Sa2.5-Sa3.0 Sa 2.5:4m/min(speed), 75-100m2/hour(Area) Sa3:3m/min(speed) Techincal
