Question $1$

A$.$ A $200$ m long inclined belt conveyor is being used to convey ore from a stockpile to the

processing plant at a speed of $1\mathrm{.}4\frac{m}{s}.$ The belt is $0\mathrm{.}75$ m $(30$ inch $)$ wide, has a capacity

of $500\frac{t}{h}r(551to\frac{n}{h}r)$ and discharges material at a height $10$ m above the loading point.

The material being conveyed has a density of $1\mathrm{.}4\frac{t}{m^3}(90l\frac{b}{f}{t}^3).$ The conveyor system is

being used for a permanent application and has the head pully lagged and an angle of

wrap of $220$ with automatic $($counterweight$)$ take up$.$ The carrying idler spacing is $1\mathrm{.}22$
