Any granulators imply that the powder will be moistened, mixed, and then the resulting granules need to be dried. The easiest way for you is to buy a household meat grinder. Moisturize your powder (what exactly you need to read in the literature on pelletizing) and then press your mass through the die of the grinder.

By the way – you can try it with and without a knife inside. The resulting sausages need to be dried. I have not met any equipment that makes dry pellets of the size you need from dry powder.

This model of granulator is a simple mechanical device that rubs the moistened powder through holes in a mesh or stainless steel sheet. The granulator: does not mix the powder; does not moisten the powder; does not mix the moistened powder; does not dry the granules; does not separate the granules into good and substandard; does not produce granules of the same shape size. The function of the granulator is to rub the moistened powder through the holes. It is simple and easy to check if the granulator is suitable for you. Prepare 1 kg of powder, moisten (having previously studied the theory and materials for moistening) to such an extent that the powder, when squeezed, leaves an imprint in the hand. Strong moistening will not form granules, neither will weak moistening. Strong moistening will require a longer drying time for the granules. Once the powder has been evenly mixed and moistened, you have a powder that is
ready for pelletizing. It is necessary to make a 400 x 400 mm frame out of wooden boards and nail a metal mesh on it. The thickness of the wire is not less than 0.5 mm, the mesh size is 2 mm by 2 mm. You put the moistened mass on the grid, with a plastic or steel spatula, wiping the powder through the grid with rubbing movements from side to side. In this way you will get samples of the granules. The quality of the granules depends on the combination of the substance that is moistened and the amount of this liquid in the mass of the powder. If you get quality granules with this experiment, you can safely buy a granulator.
