LatinDancer, I absolutely love that clipart cartoon - my kind of humour.....
The link attached describes the proccess of mixing solid propellent pretty well.
BBC - Future - The rocket scientists mixing up a giant firework
The mixer used to combine the ingredients for the fuel is one of the largest in the world, and does indeed resemble the sort of machine you might find in an industrial bakery. Its multiple rotating blades – swirling at between 500 and 1,000 times a minute but never touching the sides to avoid the risk of a spark – mix together batches of 12 tonnes of propellant at a time.
