{"text":"Just wondering whats your method of unloading. Top air, no top air.\n\nI do bulk cement in the oilfield and i see a lot of guys like using a mix of top air and aerators not all the way open. Why? I never use top air except under a few circumstances. Aerators all the way open. Once i get up to 13-15 psi open pressure control about half way and slowly crack a bottle all the way open. Once cement is flowing slowly cut back pressure control so just enough air keeps the cement from plugging up. A good running trailer and short 10ft hose and 40k gone in 35 min or so","pics":"[]","canComment":true}
