At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.

Wiped film or thin film distillation involves separating the compounds of heat-sensitive and highly viscous liquids using a vertical evaporator. As the fluid is poured into the machine, the rotor blade or wiper distributes the liquid to the evaporator's inner surface to create a thin film. The film is usually 0.1 to 0.5 mm thin.
