Mangosteen peel is a natural herbal used in wound treatments. The peel contains tannin which is good for the skin disease and xanthones, an antibiotic property for healing wound and inflammation. However, the peel must be dried and grind to powder form before it can be utilized. In this study a mangosteen peel powdering machine was designed and constructed having a pair of roller mill to reduce the size of the peel to a small chunk, and then the chunk was further reduced to powder form by using a hammer mill. The rollers were made of steel cylinder of 104 mm diameter and 400 mm length. Six steel blades each of 10 x 10 mm2 were mounted along each cylinder surface at equal space making 5° to the axial line. Hammer mill consisted of a casing 316 mm diameter, 120 mm width, having rough surface for grinding, and a hammer rotor with 28 blades each of 96 x 25 x 5.6 mm (L x W x T). The mills were powered by a 3 Hp electric motor. Testing the mills at various speeds found that the optimum speed for the roller mill was 13.4 rpm and that of the hammer mill was 1542 rpm having capacity of 11.5 kg/h with the loss of 16.07% by weight.
