Milling is used across a number of different industries and can be broadly divided into two types: wet milling and dry milling. When it comes to the manufacturing of pharmaceuticals, the particle size of ingredients is critical to a drug's performance and efficacy, so the stakes are much higher than when milling foods or other consumer goods.

Mixing of liquids can be divided into two subgroups, which are; Liquid-solid Mixing •a) Mixing of liquid and soluble solid •By simple stirring, e.g. syrup solution. •b) Mixing of liquid and insoluble solid •A liquid suspension will be produced which is an unstable product. •Suspending agent should be added to produce stable suspension.

air temperatures than in subsequent drying stages. Third phase falling rate period This is the phase during which migration of moisture from the inner side of each particle to the outer surface becomes the limiting factor that reduces the drying rate. The point C, where the drying rate begins to decrease, is called "critical moisture content".
