a cement mixing method for mixing cement used in cementing oil wells casing and the mixer used in that method . the mixer employs a straight bulk cement inlet , five annular recirculation jet and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber . the five annular recirculation jets are located in alternating longitudinal alignment within the mixing chamber relative to the five annular water jets . this five jet , intersecting flow design allows for more thorough wetting of the cement powder with a smaller , lighter , less expensive and more durable mixer that is less inclined to foul and easier to clean .
