GLOSSARY OF EQUIPMENT 92-93 manganese content). The revolving cylindrical surface can have more than one sieving area with different mesh orifice sizes, allowing material to be classified according to grain size depending on the size, shape and class of material. TYPES This equipment can be classified according to various criteria. In view of the purpose of the machine in the process, they can be classified as: • Large material trommels. In these, the mesh opening is large enough (300 to 450 mm) such that only large materials are not sifted, obtaining a sifted fraction that feeds the rest of the process and a rejected waste current of large volume material in the trommel overflow. • Fine materials trommel. Relates to trommels with small sieve sizes (40-60 mm) meant to sift organic material and small objects. • Mixed trommels. Trommels with a considerable sieving length and several meshes. As relates to the number of meshes, the trommels can be sorted into: • With one mesh passing stream and one non-passing rejected waste stream (single mesh). • With two mesh passing streams and one non-passing rejected waste stream (two meshes). 2 1.
