ABSTRACT:
A portable well treating fluid mixing system includes: a supply tank having an inlet receiving pneumatically conveyed dry treating material; a cyclone separator having an inlet coupled to the supply tank and receiving dust laden air from the supply tank, and having a first outlet venting clean air and having a second outlet venting solids; a collection container having a first inlet coupled to the cyclone separator second outlet and receiving solids from the cyclone separator and having an outlet; and, a pump having an inlet coupled to the collection container outlet and a pump outlet coupled to the supply tank. In operation, the system continuously conveys dust from the collection container back into the supply tank to maintain the separator in proper operating condition and minimizes venting of dust during the transfer of material to the supply tank.
