If the haulage arrangement includes a belt conveyor then user enters
data in Frm50 immediately below.
Note: If implementation of a belt conveyor system requires, for
example: a primary crusher station, then the capital cost of that

For example: If a mobile crusher system is less expensive than an
alternative stationary plants system.
