3. Technological aspects

In principle, the construction of a centrifuge machine is relatively simple. A cradle fitted with rollers supports a tubular mold in the horizontal plane. A safety device prevents the mold from leaving the cradle and maintains its axial position. The mold can be driven in rotation by a belt, a set of motorized rollers or other suitable means. However, it is essential to be able to vary the speed of rotation of the mold in order to adapt it to the different phases of processing.

Some machines are designed to work with a single size or type of mold, so their construction is all the simpler; others, working with several mold diameters, need to be designed accordingly. They will have variable-geometry rollers to keep the working height constant, and sufficient motorization to drive molds of different masses and correct acceleration values according to diameter. The...
