Among the KOSBEST® pharmaceutical granulation equipments, YK series rotary granulator is the most commonly used one granulator machine for pharmaceuticals. It is a wet granulation machine. After the wet-mixed powders be put into the machine, it can be automatically forced out into the uniformly sized granules through the screen mesh when under the pressing by the rotating roller. If our buyers want to make the thicker and harder particles. We suggest to adjust the screen mesh of machine to more looser and increasing more powders to work in the same batch. In turn, the granuls will be made to finer and looser.
