Effective moisture management is an important part of refractory gunning material preparation. The right refractory gunning material moisture control equipment can help operators add a controlled amount of water before material reaches the nozzle, supporting proper hydration and helping minimize rebound.
The Blastcrete Predampener is designed to add up to 5% moisture to gunning materials to support proper hydration at the nozzle. Its completely hydrostatic design provides precise material predampening and output control, while two solenoid-activated water bars allow simple water-volume adjustment.
What Is Refractory Gunning Material Moisture Control Equipment?
Refractory gunning materials require appropriate preparation before application. A Predampener provides a dedicated system for introducing controlled moisture into the material before it reaches the nozzle.
The Blastcrete Predampener combines:
Material feeding
Hydrostatic predampening
Controlled water addition
Material mixing
Output control
This integrated approach allows operators to manage the material preparation process while maintaining the desired production rate.
Controlled Moisture Addition With the Predampener
The Blastcrete Predampener can add up to 5% moisture to gunning materials. The system uses two solenoid-activated water bars to introduce water into the material.
Water volume can be adjusted simply according to the requirements of the application. This provides operators with greater control over moisture addition during refractory material processing.
The equipment is designed to support proper hydration at the nozzle while helping minimize rebound.
Hydrostatic System for Precise Material Control
A key feature of the Predampener is its completely hydrostatic design. This system allows precise control over material predampening and output.
The unit incorporates a 9-inch hydrostatic predampening auger that processes the material while controlled moisture is introduced.
Hydrostatic operation provides a dedicated method for managing material flow and moisture preparation for demanding refractory gunning applications.
High-Capacity Material Processing
The Predampener is designed for industrial material processing with an output range of 0-12 tons per hour.
Its hopper provides up to 3,000 pounds of capacity and includes a material feed screw. The high-capacity design supports continuous material handling for applications requiring substantial gunning-material throughput.
The combination of material capacity and controlled predampening makes the equipment suitable for demanding industrial operations.
Mixing Auger for Material Preparation
The Predampener includes a mixing auger with a removable rubber enclosure. The mixing system helps distribute added moisture throughout the material during processing.
The removable enclosure also provides access for inspection and maintenance.
When combined with the hydrostatic predampening auger and water bars, the mixing system provides an integrated approach to preparing gunning material before nozzle application.
Two Solenoid Water Bars
The Predampener uses two solenoid water bars for controlled water delivery.
These water bars allow simple water-volume adjustment, giving operators the ability to regulate moisture addition according to application requirements.
The system is designed to add up to 5% moisture to gunning materials, helping support consistent hydration before nozzle application.
