Oil wells may be fracture treated on-site in order to stimulate productio n. Such fracture treatment may be performed using a portable blender tub to mix fracturing fluid, proppant, and dry chemical additive into an injection slurry. A mechanical conveyance device may be adjustably attached to the por table blender tub, so that in its first position it is stowed for transport, while in its second position it is deployed for operation. When deployed, t he mechanical conveyance device may mechanically convey and meter dry chemic al additive into the blender tub, allowing a handler to feed and meter dry c hemical additive while standing on the ground. This allows for improved safe ty and efficiency in fracture treating a wellbore.
