ABSTRACT:
A method and apparatus for forming a cement or plaster slurry, for example, for use in mines, in which bags of cement or plaster are fed into a substantially closed chamber, are ruptured, and water is fed into the chamber at a controlled rate. The resulting mixture is fed into a macerator which serves to comminute the bag material and to mix the cement or plaster which is then fed into a pump, preferably a positive displacement pump, such as a helical gear pump and is thus pumped on to the point of use.
