Consistent moisture management is essential for efficient refractory gunning applications. Adding the right amount of moisture to gunning materials can help support proper hydration at the nozzle while minimizing rebound. The Blastcrete Predampener is designed as a high-capacity solution for controlled material predampening and output management.
As controlled water addition equipment, the Predampener can add up to 5% moisture to gunning materials. Its completely hydrostatic design provides precise control over predampening and material output, while two solenoid-activated water bars allow operators to make simple water-volume adjustments.
High Capacity Refractory Predampener
A high capacity refractory predampener is valuable for projects that require continuous material preparation and high production rates. The Predampener is designed with a hopper capacity of up to 3,000 pounds and an output range of 0-12 tons per hour.
This high-volume capability allows the equipment to support demanding refractory applications while maintaining controlled moisture addition.
The system combines a material feed screw, hydrostatic predampening auger, mixing auger, and water delivery system into one integrated unit.
Controlled Water Addition Equipment for Refractory Materials
The primary purpose of controlled water addition equipment is to introduce moisture into dry gunning materials in a consistent and adjustable manner.
The Predampener uses two solenoid-activated water bars to deliver water during the material predampening process. Operators can adjust the water volume according to application requirements, helping maintain the desired moisture level throughout operation.
The system is designed to add up to 5% moisture, supporting proper hydration at the nozzle while helping reduce rebound.
Hydrostatic Predampening for Better Material Control
The Predampener features a 9-inch hydrostatic predampening auger. This hydrostatic design provides control over both material predampening and output.
By combining material movement with controlled water addition, the system helps provide consistent preparation before the material reaches the nozzle.
Hydrostatic operation also gives operators greater control over the production process, which can be particularly useful during continuous refractory work.
Key Features of the Predampener
The Predampener incorporates several features designed for high-volume refractory material processing.
9-Inch Hydrostatic Predampening Auger
The 9-inch auger provides controlled material processing and moisture distribution. Its hydrostatic operation allows precise adjustment of predampening and output.
3,000-Pound Hopper
The Predampener includes a hopper with up to 3,000 pounds of capacity. A material feed screw helps move the gunning material into the predampening system.
Two Solenoid Water Bars
Two solenoid-activated water bars provide controlled water delivery. Simple water-volume adjustment gives operators the ability to fine-tune moisture addition.
Mixing Auger
The mixing auger helps distribute moisture throughout the material. Its removable rubber enclosure provides convenient access for maintenance and inspection.
20 HP Electric Motor
A 20 HP electric motor powers the unit. The system includes a disconnect and electrical enclosure and is available for 240V or 480V, 3-phase power.
Skid-Mounted Design
The skid-mounted Predampener features forklift tubing for convenient handling and positioning. This design allows the equipment to be moved using standard forklift equipment.

Supporting Proper Hydration at the Nozzle
Proper hydration is an important consideration in refractory gunning. The Predampener is designed to add controlled moisture before the material reaches the nozzle.
With the ability to add up to 5% moisture and adjust water volume through its solenoid water bars, the equipment provides operators with greater control over material preparation.
Controlled predampening can help maintain consistent material conditions and contribute to minimizing rebound during application.
Designed for Continuous Refractory Production
The 0-12 tons per hour output capacity makes the Predampener suitable for high-volume refractory operations. Its large hopper and integrated material feed system allow continuous material processing while the hydrostatic system manages predampening and output.
This combination makes the equipment a practical option for contractors and industrial operations that need dependable material preparation throughout extended applications.
Easy Handling and Optional Mobility
The standard Predampener is skid mounted with forklift tubing, allowing it to be picked up and repositioned using a forklift.
For projects requiring additional mobility, a trailer-mounted option is also available. This configuration can provide greater flexibility when equipment must be transported between locations.
