Abstract:

A technique facilitates well servicing operations by utilizing a hopper system to introduce a dry additive into a mixing tank. The hopper system comprises a feeder and a hopper that delivers the dry additive into the feeder. The feeder, in turn, enables introduction of the dry additive into the cement mixing tank in a controlled manner. When the hopper system is used on a transportable cementing unit, the hopper system may be mounted on a cement mixing tank and also may incorporate a hopper that is both expandable to accommodate a greater amount of dry additive and contractible to facilitate transport.
