Application: Metering of either large or small aggregate bulk filler material for continuous casting of polymer concrete products.
The Polymer Concrete Ground Hopper is generally used in conjunction with Gruber Systems’ Autocaster Ultra/PC (Polymer Concrete) continuous casting system or other systems. Ground Hoppers provide a longer term supply of fillers to the metering hoppers mounted on top of the Autocaster system - so that the continuous casting capability of the Autocaster is not interrupted by the need to resupply the metering hoppers.
Shown at right are two Gruber Systems' Polymer Concrete Ground Hoppers, supplying a Gruber Systems' Autocaster Ultra/PC (Polymer Concrete) continuous casting system with Aggregate Bulk Fillers. Each filler supply in turn keeps the metering hoppers on the top of the Autocaster continuously supplied with aggregate to enable continous operation of the casting system.
Ground Hopper 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 transport of any required filler material.
Gruber offers different Ground Hoppers that are specifically designed for transferring Polymer Concrete fillers:
Auger based - three different options for fine particles, small aggregates, or larger aggregates
Belt-Drive based - for the largest aggregates such as stones
Polymer Concrete Ground Hoppers Include:
Designed to handle the demanding requirements of metering large rock or highly abrasive aggregates for polymer concrete and other specialized cast polymer manufacturing applications.
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.
The Small Aggregate Ground Hopper is an auger-screw driven conveyor, typically used to convey very small aggregates such as sand, and other granules no larger than sand, 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.
