Powder hydration systems with mixing apparatus and methods of use

A powder mixing system comprising:

• a conduit having a first end and an opposing second end, the conduit bounding a passage,
• a fluid pump fluid coupled to the conduit, the fluid pump being configured to pump a liquid through the passage of the conduit;
• a
• tubular transfer member in fluid communication with the conduit, the transfer member configured to couple to a powder bag housing a powder;
• and
• further comprising:
• an eductor coupled to the transfer member and disposed in-line with the conduit so that the liquid pumped through the conduit also passes through the eductor;
• and
• an auger assembly comprising an auger blade, at least a portion of the auger assembly being rotatably disposed within the transfer member;
• and
• wherein the eductor comprises a venturi;
• and
• wherein the conduit further comprises a sidewall encircling the passage, a side opening extending through the sidewall and communicating with the passage;
• and
• the auger assembly comprising:
• a rotatable drive shaft passing through the side opening of the conduit so that a lower portion of the drive shaft is disposed within the passage of the conduit and an upper portion of the drive shaft is at least partially disposed within passage of the transfer member;
• and
• the tubular transfer member bounds a passage and the transfer member further comprises a first end fluid coupled to the side opening of the conduit and an opposing second end configured to couple with the powder bag;
• and
• the auger blade disposed on the upper portion of the drive shaft so as to be at least partially disposed within the passage of the transfer member.
