Materials Handling

Arthur Pinto Chaves

Materials handling is the fifth vollume of Theory and practice of ore treatment collection, discussing the storage in mining and metallurgy plants due to climate or geographical related questions and transport difficulties or material homogenization needs.

The book approaches themes such as storage and homogenization, pile storage, storage in silos, feeders, belt transporters, sampling and its theoretical fundaments, rejects disposition, pile dimensioning models, dam construction and incremental sampling methods and devices.

Materials handling, extremely didactic, is an essential book for those who deal with the handle of solids rejects, including the education and training, such as in the other collection volumes.
