Abstract: A mobile cement batch mixing plant includes at least one slurry tank, a cement storage tank, at least one slurry pump and at least one clean pump supported on a transportable frame. The slurry tanks and cement storage tank are connected by a plumbing system. The flow of water and cement slurry between the tanks and within the plumbing system is controlled by a series of valves and pump controls. A cement slurry is formed by adding water and cement to the slurry tank through a fluid vortex within the slurry tank. The cement slurry can be pumped out of the slurry tank into a well.
