Consider the following statements about belt conveyors:

1. Capacity depends on belt width, speed and load cross-section.

2. Power depends on the length of the run.

3. A plain belt can be inclined to 45 degrees with grain.

Which of the statements given above is or are correct?

  • A.1, 2 and 3
  • B.1 and 2 only
  • C.1 and 3 only
  • D.2 and 3 only

Answer: B

Correct answer: 1 and 2 only

Statements 1 and 2 are correct: capacity comes from the load cross-section and the speed, and power grows with length. Statement 3 is far out - grain begins to roll back on a plain belt at about twenty degrees, and 45 degrees would need cleats or an entirely different machine.
