Thank you for answer. Yes, the shot moves from the botton storage by the wide dark hose with internal diameter 25mm. The air hose is white.
I tried to find some information, some sites said that probably the abrasive hose is too wide, or i should use regulator to control the consumption of abrasive. I will try to use much narrow hose. May be it will help to fix the flow.
