Abstract

A apparatus and method of use for mixing a particulate composition and a liquid for oilfield cementing applications method is disclosed. The apparatus is capable of mixing a dry particulate with a liquid to form a cement slurry at high mixing rates. A jet spray nozzle and a mixing zone operably connect to a barrel that transmits slurry along its length. The slurry may recirculated by pumping to prepare a cement mixture for oilfield cementing operations.
