P&Q University Lesson 8- Screening : Pit & Quarry
A screen that processes 300 tons per hour would limit profits and cap growth potential. A machine with a potential output of 900 tons per hour would come with extra expenses and no added value. Scalping and screening have several main differences. Standard screens are often considered finishing screens because they're capable of producing ...
