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 to fill the metering hoppers of Autocaster and Batchmaster metering machines. Does not include self-metering.

  • No overhead mountings
  • Eliminate waste
  • Precise metering available
  • Eliminate laborious manual bulk powder handling and tank filling
  • Stationary or mobile versions available!

Bulk filler handling systems can be integrated with your continuous casting system, and metering or batching systems to reduce labor cost, improve production efficiencies, reduce wastage (material cost), and likely reduce overhead costs.

This Standard Powder Ground Hopper is most often used in conjunction with our Autocaster continuous casting systems, or the Batchmaster metering systems - delivering bulk filler powder or fine granules as needed to the metering hoppers of the Autocaster or Batchmaster. Both Autocaster and Batchmaster include a sensor that when the material level runs low, a signal is sent that turns on the Ground Hopper, which begins filling the metering hoppers atop the Autocaster or Batchmaster machines, Once the high sensor indicates the metering hopper is once again full, it suspends delivery flow from the Ground Hopper until the next signal is given. This system does not include self-metering features that may be required of some batching applications. For a self-metering Ground Hopper for batching applications. see the Self-Metering Ground Hopper.

Gruber Ground Hoppers can accommodate either bulk bags (super sacks) or individual bags of filler, as well as other granular substances for even greater efficiency. A complete bulk filler handling system often includes the ground hopper to storing and convey the materials to the point of insertion or use, and a gantry or other material transfer system to store and deliver super sacks or bulk bags to the ground hopper.

Features:

  • 50 lb (23 kg) per minute output capability (calcium carbonate or equivalent volumes*)

  • Mobile version available with wheels - or upgrade the stationary standard ground hopper with upgrade kit.

  • Transport auger constructed from carbon steel,  standard pitch (4") (i.e. pitch = distance between flights); choice of 45 degree (standard configuration) or optional 60 degree incline. Custom auger configurations available upon request.

  • Overall height 57.5” x 42.5” x 45” (LWH) excluding auger

  • Large, rugged 15 cubic feet capacity bin constructed of 12 gauge carbon steel

  • Powerful 1 HP 120/230/460 volt motor; upgrade up to 3 HP maximum

  • Sealed dust tight drive and idler bearings with transmission ratio of 20:1 (standard)

  • Pneumatic vibrator for anti-bridging control

  • 2-way forklift entries for convenient positioning

  • Includes screen for reducing introduction of bag scraps and other debris from reaching auger

  • Includes chain clamps for securing bulk bag hopper support

 

* Weight depends on specific gravity of material.

 

Other Ground Hoppers include Self-Metering (for specialized batching applications), Pneumatic Transport, Polymer Concrete (application-specific) and Mobile Ground Hopper models.

New ProductNow, convert your auger-transport style Standard (Powder) Ground Hopper with an air/pneumatic operation with these upgrades:

If you need more room around your Autocaster continuous casting system, or your Batchmaster metering system, or you are considering purchasing an Autocaster or Batchmaster, then you should carefully consider these space and cost-saving Ground Hopper conversion options to convert your existing Powder (Standard) Ground Hopper to pneumatic operation. Pneumatic operation offers extended distance transporting of powder, so you can relocate the Ground Hopper to a more distant location and free up space in your congested casting stantion area. Or, reduce by one-half the number of Ground Hoppers required by converting them to a pneumatic powder pump equipped with a dual-feed diverter valve and control system shown below. 

Auger-Transport Ground Hopper Conversion/Upgrade Options:

  • Pneumatic (Air Operation) Retrofit Kit for Single Powder Feed (supply 1 Metering Hopper) - convert a Ground Hopper to supply powder to a single metering hopper on either a Gruber Autocaster or Batchmaster metering system - #1000AGHPNCV

  • Pneumatic (Air Operation) Retrofit Kit for Dual-Feed (supply 2 Metering Hoppers) - kit includes Pneumatic Pump, Controller and Dual-Feed Diverter Valve to convert a single Ground Hopper to supply powder to two metering hoppers on either a Gruber Autocaster and/or a Batchmaster metering system - #1000AGHPNCV-2

Note: Please refer to Pneumatic-Transport Powder Ground Hoppers for more information about the potential cost-saving benefits of pneumatic-transport Ground Hoppers for your operation!
