Ground Hoppers metering bulk fillers to continuous casting systems

Ground Hoppers

Gruber Ground Hoppers meter and convey bulk fillers to the point of use (usually a Gruber Autocaster continuous casting machine. Ground Hoppers are offered for a variety of applications - including Cultured Marble, Solid Surface, Polymer Concrete and other Bulk Powder metering or conveying requirements - for all types of bulk fillers such as powders, granules, aggregates and even larger stone.

Bulk Bag Suspenders mount to the top of Ground Hoppers to stage an extra super sack full of filler above the Ground Hopper

Bulk Bag Suspender Frame

The optional Bulk Bag Suspender Frame allows the option of mounting larger, more economical bulk bags (“Super Sacks”) above Gruber’s Ground Hopper™ bulk solids conveyors. Mounting large bulk bags reduce interruptions during the manufacturing process, and reduces labor costs normally associated with manual loading of a metering or feed hopper – particularly when compared to manual loading of smaller bulk material bags. Automation of the bulk material handling system also results in a cleaner, safer working environment and more efficient manufacturing workflow.
