Consistent moisture control is an important part of preparing dry gunning materials for refractory applications. The Blastcrete Predampener is designed as refractory material dampening equipment that can add up to 5% moisture to gunning materials to support proper hydration at the nozzle and help minimize rebound.
The system uses a completely hydrostatic predampening process, allowing precise control of material predampening and output. With a high-capacity hopper, material feed screw, mixing auger, and adjustable water system, the Predampener provides an integrated solution for industrial material preparation.
What Is Refractory Material Dampening Equipment?
Refractory material dampening equipment is designed to introduce a controlled amount of moisture into dry gunning materials before application. Consistent dampening can help prepare the material for proper hydration at the nozzle.
The Blastcrete Predampener features a 9-inch hydrostatic predampening auger and two solenoid-activated water bars. Operators can adjust water volume to control the moisture introduced into the material during processing.
Refractory Material Moisture Control
Effective refractory material moisture control requires consistent water addition and material mixing. The Blastcrete Predampener combines these functions in a single system.
The two solenoid water bars provide adjustable water volume, while the hydrostatic auger is designed for precise predampening and output control. The mixing auger then helps process the material as it moves through the system.
This controlled approach is designed to add up to 5% moisture to gunning materials.
Key Features of the Blastcrete Predampener
The Predampener includes features designed for industrial refractory material processing:
9-inch hydrostatic predampening auger
Mixing auger with removable rubber enclosure
Hopper capacity of up to 3,000 pounds
Material feed screw
Two solenoid-activated water bars
Adjustable water volume
20 HP electric motor
Electrical disconnect and enclosure
Skid-mounted design with forklift pickup tubing
Optional trailer-mounted configuration
Precise Moisture Addition for Gunning Materials
One of the primary advantages of dedicated refractory material dampening equipment is the ability to control moisture addition before the material reaches the nozzle.
The Blastcrete Predampener can add up to 5% moisture to gunning materials. The adjustable water bars allow operators to modify water volume according to the material and application requirements.
The hydrostatic system is designed to provide precise predampening and output control, helping create a more consistent material-conditioning process.
High-Output Refractory Dampening System
The Blastcrete Predampener provides an output capacity of 0–12 tons per hour. This high-capacity design makes it suitable for industrial operations requiring continuous gunning-material preparation.
The unit features a hopper capable of holding up to 3,000 pounds of material. Its skid-mounted construction includes forklift pickup capability for equipment handling and positioning.

Industrial Applications
Reliable refractory material moisture control can be valuable in industrial gunning applications where consistent material preparation is required. The Blastcrete Predampener combines moisture addition, material feeding, and mixing in one machine.
Its hydrostatic operating system is designed to provide controlled material conditioning, while the high-capacity hopper and 0–12 tons-per-hour output support larger-scale operations.
Why Use a Dedicated Predampener?
Using dedicated refractory material dampening equipment allows contractors to control moisture addition before the material reaches the application nozzle. This can make the material-conditioning process more consistent and easier to manage.
The Blastcrete Predampener combines a hydrostatic auger, mixing auger, material feed screw, and adjustable water bars with a 20 HP electric drive. The equipment is also stated to be recommended by major refractory material manufacturers, according to the supplied product information.
