Answer 1

The correct answer is (b) Used to lift coal vertically

Easy explanation: Centrifugal and continuous types of bucket elevators are used for lifting coal to moderate height (about 30m). It consists of buckets fixed to a chain moving over two sprockets. The buckets carry coal from bottom and discharge at the top at a speed ranging between 15 m/min to 36 m/min.
