Controlled moisture addition is an important part of preparing refractory gunning materials. A refractory predampener with solenoid water bars provides a practical way to introduce a controlled amount of water into gunning materials before they reach the nozzle.
The Blastcrete Predampener is designed to add up to 5% moisture to gunning materials to support proper hydration at the nozzle while helping minimize rebound. Its completely hydrostatic design provides precise material predampening and output control, while two solenoid-activated water bars allow simple water-volume adjustment.
What Is a Refractory Predampener?
A refractory Predampener is designed to introduce controlled moisture into dry gunning materials before nozzle application. The equipment combines material feeding, moisture addition, predampening, and mixing into one system.
The Blastcrete Predampener uses a hydrostatic predampening system and two solenoid water bars to help operators manage the material preparation process.
This approach provides controlled moisture addition while maintaining material output.
Refractory Predampener With Solenoid Water Bars
The key feature of this refractory predampener with solenoid water bars is its two solenoid-activated water bars.
The water bars provide controlled water delivery, while simple water-volume adjustment allows operators to regulate the amount of moisture added to the gunning material.
The system is designed to add up to 5% moisture, supporting proper hydration at the nozzle and helping minimize rebound.
Hydrostatic Predampening System
The Blastcrete Predampener features a 9-inch hydrostatic predampening auger.
Its completely hydrostatic operation allows precise material predampening and output control. As material moves through the system, water is introduced through the solenoid water bars.
This integrated process gives operators greater control over material preparation before the gunning material reaches the nozzle.
Two Solenoid Water Bars for Water Control
The two solenoid water bars are designed to provide controlled moisture addition.
Simple water-volume adjustment allows operators to modify water delivery according to the requirements of the refractory application. Controlled water addition can help maintain consistent material preparation.
The Predampener is designed to add up to 5% moisture to gunning materials.
Mixing Auger With Removable Rubber Enclosure
The Predampener incorporates a mixing auger with a removable rubber enclosure.
The mixing auger helps distribute added moisture throughout the gunning material as it moves through the equipment. The removable enclosure provides access for inspection and maintenance.
The combination of the mixing auger, hydrostatic predampening auger, and water bars provides an integrated material-preparation system.
High-Capacity Material Handling
The Predampener is designed for industrial refractory applications with an output range of 0-12 tons per hour.
Its hopper can accommodate up to 3,000 pounds of material and includes a material feed screw.
This capacity allows the equipment to handle substantial quantities of gunning material while maintaining controlled predampening and material output.

Supporting Proper Hydration at the Nozzle
The Blastcrete Predampener is designed to add moisture to gunning materials before nozzle application.
The controlled water system and hydrostatic predampening process support proper hydration at the nozzle while helping minimize rebound.
Operators can adjust water volume through the solenoid water bars while managing material predampening and output through the hydrostatic system.
Choosing a Refractory Predampener
When selecting a refractory predampener with solenoid water bars, consider production capacity, hopper requirements, moisture-control needs, available electrical power, equipment dimensions, and mobility.
