Crushing, Screening and Grinding
Arthur Pinto Chaves , Antônio Eduardo Clark Peres
New edition, revised and enhanced. The highlights are an unpublished text about automation and crushing installation control and an extra chapter, completely dedicated to fine grinding.
The book now counts with five chapters: one about crushing, its equipments and processes, crushing and undergroung mining, impact crushers, etc. Another approaching screening, its constructive characteristics, types of screen and humidity effects.
Then comes an introductory chapter about grinding, with equipments, wet and dry grinding, ball mills, Bond and Rowland dimensioning models and possibility trapezoid method.
The last two chapters are, respectively, about coal comminution and the extra material about fine grinding and regrinding in mills with rotors agitated load.
