Consistent preparation of refractory gunning materials is important for demanding industrial applications. A predampening system for industrial refractory applications provides a controlled way to add moisture to gunning materials before they reach the nozzle, helping support proper hydration and material consistency.
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 allows precise material predampening and output control, while two solenoid-activated water bars provide simple water-volume adjustment.
What Is a Refractory Predampening System?
A refractory predampening system is equipment designed to introduce controlled moisture into dry gunning materials before nozzle application.
The Blastcrete Predampener combines several material-preparation functions in one machine, including:
Material feeding
Hydrostatic predampening
Controlled water addition
Material mixing
Output control
This integrated approach provides operators with greater control over the preparation of refractory gunning materials.
Predampening System for Industrial Refractory Applications
Industrial refractory applications often require equipment capable of handling substantial material volumes while maintaining controlled moisture addition.
The Blastcrete Predampener provides an output range of 0-12 tons per hour and has a hopper capacity of up to 3,000 pounds.
The system is designed to add up to 5% moisture to gunning materials. Controlled predampening supports proper hydration at the nozzle and is intended to help minimize rebound during application.
Hydrostatic Predampening Auger
A 9-inch hydrostatic predampening auger is one of the primary components of the system.
The completely hydrostatic design provides precise material predampening and output control. Material passes through the auger while water is introduced through two solenoid-activated water bars.
This provides an integrated process for preparing refractory gunning material before nozzle application.
Controlled Water Addition
The Predampener features two solenoid water bars for controlled water delivery.
Simple water-volume adjustment allows operators to regulate moisture addition according to the application requirements.
The system is designed to add up to 5% moisture to gunning materials, providing controlled predampening before the material reaches the nozzle.
Mixing Auger for Material Preparation
The equipment includes a mixing auger with a removable rubber enclosure.
The mixing auger helps distribute added moisture throughout the gunning material during processing. The removable enclosure provides access for inspection and maintenance.
Combined with the hydrostatic predampening auger, the mixing system supports consistent material preparation.
High-Capacity Hopper and Material Feed Screw
The Predampener features a hopper capable of holding up to 3,000 pounds of material.
An integrated material feed screw moves gunning material through the system for predampening and mixing.
With an output range of up to 12 tons per hour, the equipment is designed for high-volume industrial refractory material processing.

Supporting Proper Hydration at the Nozzle
The Blastcrete Predampener is designed to add controlled moisture before gunning materials reach the nozzle.
The combination of hydrostatic predampening, adjustable water delivery, and mixing provides operators with greater control over material preparation.
The equipment is designed to support proper hydration at the nozzle while helping minimize rebound.
Selecting a Predampening System
When choosing a predampening system for industrial refractory applications, consider production capacity, hopper size, moisture requirements, electrical power, available space, and equipment mobility.
The Blastcrete Predampener offers a 0-12 tons-per-hour output range, a 3,000-pound hopper, a 9-inch hydrostatic predampening auger, two solenoid water bars, and a 20 HP electric motor.
These features provide an integrated solution for industrial refractory gunning material preparation.
