Ground Hoppers for standalone applications (not involving an Autocaster or Batchmaster) include:

Self-Metering Weight Loss Ground Hopper

new Weight Loss Self-Metering Ground Hopper

For applications not involving an Autocaster or Batchmaster system

This all new Weight-Loss Self-Metering Ground Hopper that utilizes load cells and a sophisticated PLC Control System for highly accurate weight-loss powder metering for a wide variety of metering, batching and conveying applications. Machine control is provided by a PLC-equipped Control Panel

Ground Hoppers for use with Gruber Autocaster Continuous Casting Systems include:

Ground Hopper for use with Autocaster
 

Standard (Powder/Granule) Ground Hopper

For use with Autocaster Continuous Casting Systems

Our standard auger-driven transport system Ground Hopper made for use with our Autocaster casting machine provides reliable conveying of powders such as calcium carbonate blends, ATH blends, as well as granules and other fine particle or lightweight fillers. The Autocaster controls its operation.

 
 
Small Aggregate Ground Hopper

Small Aggregate and Large Aggregate Top Mount Ground Hoppers

Both are designed for use with Gruber's Autocasterâ„¢ continuous casting systems for Polymer Concrete Manufacturing
These two very similar Ground Hoppers are designed for conveying aggregates for Polymer Concrete Casting - and are both the newest Top Mount design that includes the motor and transmission at the top of the Groud Hopper Auger to greatly reduce wear and tear on those key components. Both are "screw-drive" style transport mechanisms that utilize a durable auger system.

The Small Aggregate Ground Hopper conveys smaller aggregates such as sand, granules and small pea gravel up to 1/8" diameter, as well as granular powders.

The Large Aggregate Ground Hopper conveys larger-sized aggregates such quartz, pea gravel or small rock up to as large as 3/8" (7 mm) diameter, although it can also easily accomodate smaller aggregates such as sand, granules and very small pea gravel.

 
Belt-Drive Ground Hopper for Highly Abrasive Aggregate

 

Belt-Drive Ground Hopper for Highly Abrasive Aggregate

Gemerally for use with Autocaster Continuous Casting Systems for Polymer Concrete Manufacturing Applications

Transfer lightweight bulk fillers over extended distances to your Autocaster utilizing a positive pneumatic pressure (air) transport system. This eliminates the requirement for an auger, and allows the Ground Hopper to be placed in a more remote location - out of the way of the Autocaster casting system.

 

Recommended for transporting Lightweight Fillers to the Autocaster casting machine from Ground Hoppers located at greater distances:

Pneumatic Ground Hopper for Lightweight Powder Fillers

Pneumatic Ground Hopper for Lightweight Powder Fillers

Gemerally for use with Autocaster Continuous Casting Systems

Automatically meter and transfer lightweight filler material over extended distances with a Pneumatic-transport Ground Hopper. This eliminates the requirement for an auger, and allows the Ground Hopper to be placed in a more remote location - out of the way of the Autocaster casting system or the Batchmaster mixing station.


Ground Hoppers for use with Gruber Batchmaster batching machines include:

Ground Hopper for use with Batchmaster

 

Powder/Granule Ground Hopper for Batchmaster

For use with Batchmaster Batching Machine

Our standard auger-driven transport system Ground Hopper made for use with our Batchmaster batching machine provides reliable conveying of powders such as calcium carbonate blends, ATH blends, as well as granules and other fine particle or lightweight fillers. The Batchmaster machine controls its operation.

Ground Hopper Accessories

Gruber Ground Hoppers accommodate either bulk bags (super sacks) or individual bags of filler. The Ground Hopper is one element of a complete bulk filler handling system. Gruber offers a number of other bulk filler handling accessories further automate or customize its integration into your workflow:

Bulk Bag Suspender Frame Bulk Bag Gantry Bulk Bag Roller Conveyor Suspender Cross Frame
 BulkBagSus100  166200 325 BBConvey wPallet150   suspender cross frame130
Hangs a bulk bag above a Ground Hopper - doubling the capacity of the Ground Hopper. The Bulk Bag Gantry aids lifting of bulk bags into position (over the bulk bag suspender). Two sizes - 10’ or 15' Bulk Bag Roller Conveyor easily transports super sacks to the ground hopper. Accessory to a Bulk Bag Gantry to lift/suspend the Bulk Bag.
