Abstract
A process for making slurries is provided. The process comprises providing a liquid component and a solids component; introducing the liquid component into a mixing vessel having pitched blade turbines; adding at least 25% of the solids component into the mixing vessel; initiating an in-line rotor stator positioned to receive the mixture from the mixing vessel; and re-circulating the mixture from the mixing vessel through the in-line rotor stator and back to the mixing vessel.
Claims10
A process for making a mixture comprising:
- providing a liquid component and a solids component, the solids component having a specific gravity of 2.0-3.5 having particles with a diameter of 5-50 microns, the liquid component having particles comprising from 5-65% by weight based on the weight of the liquid component and a viscosity of 10-10,000 cps;
- introducing the liquid component into a mixing vessel having a set of pitched blade turbines, the pitched blade turbines positioned inside the mixing vessel according to the ratios:
- D/T
- 0.45-0.55,
- C/T
- 0.07-0.35,
- S/T
- 0.18-0.47, and
- H/T
- 0.09-0.65;
- adding at least 25% of the solids component into the mixing vessel;
- initiating an in-line rotor stator positioned to receive the mixture from the mixing vessel;
- and
- re-circulating the mixture from the mixing vessel through the in-line rotor stator and back to the mixing vessel.
