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 and for standalone use

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. Can be used as standalone Ground Hopper, but base unit lacks controls. When not used with Autocaster, optional controls can be added including On/Off and Speed Controls.

 
 
Small Aggregate Ground Hopper

Small Aggregate and Large Aggregate Top Mount Ground Hoppers

Both are designed for use with Gruber's Autocaster™ 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.

Gruber Standard Powder/Granule Ground Hopper

Our standard auger-driven transport system Ground Hopper provides reliable conveying of powders such as calcium carbonate blends, ATH blends, as well as granules and other fine particle or lightweight fillers. Most commonly, these are used to fill the filler metering hoppers used with our Autocaster™ continuous casting machine and Batchmaster metering machines - however, these can be used with other equipment and other applications as well.

Weight Loss version Self-Metering Ground Hopper

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

Gruber Pneumatic Ground Hopper

Automated metering of lightweight powder bulk filler over extended distances utilizing a positive pneumatic pressure (air) transport system.

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.

newNow, you can supply lightweight powder fillers like CalCarb/Lightweight powder blends and ATH blends to TWO different metering hoppers from a single Pneumatic Ground Hopper with the Dual-Feed model!

Bulk filler handling systems can be integrated with your process or batching system to reduce labor, improve efficiencies, aid in material cost control, and potentially lower overhead costs.

Gruber Mobile Ground Hoppers

For situations where you need your Ground Hopper to be movable or portable.

In some cases, your bulk filler handling system is not required to be a fixed location, and you may benefit by moving your Gruber Ground Hopper to where you need it for a given use. Portability offers added convenience and added value to your Bulk Filler Handling investment.

 
Batchmaster-specific Ground Hopper and Bulk Bag Suspender Frame

Special version Gruber Ground Hopper and Bulk Bag Suspender Frame option for use with the Batchmaster III Metering System.

Gruber Polymer Concrete Aggregate Belt Drive Ground Hopper

Designed to handle the demanding requirements of metering large rock or highly abrasive aggregates for polymer concrete and other specialized cast polymer manufacturing applications.

Gruber Large Aggregate Ground Hopper

The "Top-Mount" Large Aggregate Ground Hopper is an auger-screw driven conveyor, typically used to convey larger-sized such quartz, pea gravel or small rock up to as large as 3/8" (7 mm) diameter used in Polymer Concrete Casting applications. This machine is normally used to convey fillers to the filler metering hoppers included with Gruber's Autocaster™ continuous casting machine. It can also easily handle smaller aggregates such as sand, granules and very small pea gravel.

Small Aggregate PC Ground Hopper

The "Top-Mount" Small Aggregate Ground Hopper is an auger-screw driven conveyor, typically used to convey smaller aggregates such as sand, granules and small pea gravel up to 1/8" diameter, as well as granular powders. This machine is normally used to convey fillers to the filler metering hoppers included with Gruber's Autocaster™ continuous casting machine.

Bulk Filler Management 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.
