Proper preparation of refractory gunning materials is an important part of achieving consistent application performance. A Predampener for refractory gunning materials is designed to introduce controlled moisture into dry material before it reaches the nozzle, helping support proper hydration while minimizing rebound.
The Blastcrete Predampener can add up to 5% moisture to gunning materials. Its completely hydrostatic design provides precise control over material predampening and output, while two solenoid-activated water bars provide simple water-volume adjustment.
What Is a Predampener for Refractory Gunning Materials?
A Predampener is a material-preparation machine designed to add a controlled amount of moisture to refractory gunning materials before application.
Instead of relying solely on moisture addition at the nozzle, the Predampener prepares the material in advance. The system combines material feeding, hydrostatic predampening, mixing, and controlled water addition in one unit.
This helps operators manage material conditions and production rates during refractory gunning operations.
Controlled Moisture Addition
The Blastcrete Predampener is designed to add up to 5% moisture to gunning materials. Controlled moisture addition helps support proper hydration at the nozzle and can contribute to minimizing rebound.
The equipment uses two solenoid-activated water bars to introduce water into the material. Operators can make simple adjustments to the water volume according to the application requirements.
This provides greater control over the predampening process during continuous operation.
Hydrostatic Predampening for Precise Material Control
The Predampener features a 9-inch hydrostatic predampening auger. Its hydrostatic design allows precise control of both material predampening and output.
As material moves through the system, moisture is introduced through the water bars and distributed through the material with the help of the mixing system.
The result is a controlled material-preparation process designed for demanding refractory applications.
High-Capacity Refractory Material Processing
The Predampener provides an output range of 0-12 tons per hour, making it suitable for high-volume refractory gunning operations.
A hopper with a capacity of up to 3,000 pounds provides substantial material storage. The integrated material feed screw helps move material through the system for continuous processing.
This combination of capacity and output can support operations where consistent material preparation and production are important.

Mixing Auger for Consistent Material Preparation
The Predampener incorporates a mixing auger with a removable rubber enclosure. The mixing system helps distribute added moisture throughout the gunning material during processing.
The removable enclosure also provides convenient access for inspection and maintenance.
Together with the hydrostatic predampening auger, the mixing system helps provide controlled material preparation before the material proceeds to the nozzle.
3,000-Pound Material Hopper
High-volume refractory operations can benefit from equipment with sufficient material storage. The Predampener's hopper provides up to 3,000 pounds of capacity.
The material feed screw helps deliver material from the hopper into the predampening system, supporting continuous processing.
Combined with the machine's 0-12 tons-per-hour output, the hopper is designed for demanding industrial applications.
20 HP Electric Motor and Power Options
The Predampener is powered by a 20 HP electric motor and includes a disconnect and electrical enclosure.
Available power options include:
240V, 3-phase
480V, 3-phase
Selecting the appropriate electrical configuration allows the equipment to be matched to the power requirements of the operating facility or job site.
Skid-Mounted Design and Forklift Pickup
The standard Predampener is skid mounted and includes forklift tubing. This design allows the unit to be lifted and repositioned using a forklift.
For projects where increased mobility is required, an optional trailer-mounted configuration is available.
These mounting options provide flexibility for different industrial refractory applications.

Supporting Proper Hydration at the Nozzle
Proper hydration is an important consideration when applying refractory gunning materials. The Predampener is specifically designed to add controlled moisture before the material reaches the nozzle.
By combining adjustable water delivery with hydrostatic material processing, the system helps operators maintain control over the moisture and output of the material.
The equipment is designed to support proper hydration while helping minimize rebound during application.
Choosing the Right Predampener
When selecting a Predampener for refractory gunning materials, consider the required material output, hopper capacity, moisture requirements, electrical supply, and equipment mobility.
The Blastcrete Predampener provides a combination of high-capacity material handling, hydrostatic predampening, adjustable water delivery, and flexible mounting options.
For operations requiring controlled and consistent material preparation, these features can provide a practical solution for refractory gunning applications.
