Application: Metering of either large or small aggregate for continuous casting of polymer concrete products.
The Polymer Concrete Ground Hopper automates the metering and batching of either small or large aggregates for polymer concrete matrix. Use of the Ground Hopper reduces labor costs, improves production efficiencies, reduces wastage (material cost), and likely reduces overhead costs.
Benefits:
- Precise, automated metering eliminates waste
- Eliminate labor costs of manual bulk material handling and tank filling
- No overhead mountings
- Compliments a continuous casting system (like the Gruber Autocaster Ultra Polymer Concrete version) by automating the metering of aggregate fillers
Two models are offered – a small aggregate version, and a large aggregate version for processing of larger aggregates of up to 3/8” (7 mm) – such as:
- Quartz
- Sand
- Pea Gravel
- Small Rock
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 Roller Conveyor easily transports super sacks to the ground hopper. Bulk Bag Suspender Frame allows suspension of extra bulk filler material (bulk bags) above the ground hopper for additional processing capabilities. The Bulk Bag Gantry aids lifting of bulk bags into position (over the bulk bag suspender).
The Polymer Concrete Ground Hopper is generally used in conjunction with Gruber Systems’ Autocaster Ultra Polymer Concrete (P/C) continuous casting system (also shown at right).
Gruber produces a variety of other Ground Hoppers for metering of other composite materials, and can custom configure a Ground Hopper to your specific needs for other materials or applications. Please call to discuss your needs.
The Polymer Concrete Ground Hopper differs from Gruber's standard Ground Hopper by incorporating heavier-duty, “industrial-strength” components that withstand the processing of abrasive aggregates like those found in Polymer Concrete. These key features include:
-
Reinforced auger tube for extended durability and lifespan.
-
Strengthened progressive auger for longer wear life and to reduce weight in the lifting tube.
-
Feed shutoff slide to allow the auger to empty before stopping preventing binding at startup and reduced weight in tube when at rest.
Other features include:
- 500 cu/in per minute throughput capacity (based on calcium carbonate blends)
- Solid core auger constructed from carbon steel, progressive pitch. 45 degree incline
- 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 3 HP 120/230/460 volt motor
- Sealed dust tight drive and idler bearings with transmission ratio of 10:1 (standard)
- 2-way forklift entries for convenient positioning
- Screen for reducing introduction of bag scraps and other debris from reaching auger
- Chain clamps for securing bulk bag hopper support
