Similar to the impex pulverizers, Miracle mill/ Hammer mill is also useful for high production, though the fineness of materials are not as perfect as that of pulverizers. These mils are provided with perforated liners, which are fitted in the bottom half of the grinding chamber. The hole diameter and pitch is decided as per the required size of mesh. Unlike the pulverizers, these do not require whizzers as the materials are already classified by the perforated liners.
