Proper moisture management is an important part of refractory gunning. When gunning materials receive the appropriate amount of moisture before reaching the nozzle, operators can better control material preparation and support consistent application. A Predampener for proper refractory hydration is designed to provide controlled moisture addition while helping minimize rebound.
The Blastcrete Predampener can add up to 5% moisture to gunning materials to support proper hydration at the nozzle. Its completely hydrostatic design allows precise control of material predampening and output, while two solenoid-activated water bars provide simple water-volume adjustment.
What Is a Predampener?
A Predampener is a specialized piece of equipment used to introduce controlled moisture into dry gunning materials before nozzle application.
The Blastcrete Predampener combines material feeding, moisture addition, hydrostatic predampening, and mixing in one system. This allows operators to prepare gunning material with a controlled amount of moisture before it reaches the application point.
For refractory contractors, this can provide greater control over the material preparation process.
Predampener for Proper Refractory Hydration
The main purpose of a Predampener for proper refractory hydration is to introduce moisture in a controlled manner before the material reaches the nozzle.
The Blastcrete Predampener is designed to add up to 5% moisture to gunning materials. Two solenoid-activated water bars provide adjustable water delivery, allowing operators to make simple changes to water volume.
The hydrostatic system also provides precise control over material predampening and output.
Why Moisture Control Matters in Refractory Gunning
Moisture consistency can be an important factor in refractory gunning applications. Too little or inconsistent moisture can affect material preparation, while uncontrolled water addition can make it difficult to maintain consistent operating conditions.
The Predampener provides a dedicated system for controlled moisture addition. Its adjustable water bars and hydrostatic predampening auger allow operators to manage the process according to application requirements.
The equipment is designed to support proper hydration at the nozzle while helping minimize rebound.
9-Inch Hydrostatic Predampening Auger
The Predampener features a 9-inch hydrostatic predampening auger that provides controlled material movement and predampening.
Its hydrostatic design allows operators to regulate material output and predampening, providing a consistent approach to preparing gunning materials.
As material passes through the system, controlled water is introduced through the two solenoid water bars.
Two Solenoid Water Bars for Adjustable Moisture
The Predampener is equipped with two solenoid-activated water bars. These provide controlled water delivery and simple water-volume adjustment.
Operators can adjust the water volume according to material and application requirements. The equipment is designed to add up to 5% moisture to the gunning material.
This controlled approach helps support consistent material preparation before the nozzle.
High-Capacity Material Processing
The Predampener is designed for high-volume refractory applications with an output of 0-12 tons per hour.
Its hopper can hold up to 3,000 pounds of material and includes a material feed screw for controlled material delivery.
The combination of high hopper capacity and material output makes the unit suitable for demanding industrial operations.
Mixing Auger for Material Preparation
A mixing auger with a removable rubber enclosure helps distribute moisture through the material during processing.
The removable enclosure provides convenient access for inspection and maintenance, while the mixing process helps prepare the material before it proceeds toward the nozzle.

Skid-Mounted Design With Forklift Pickup
The standard Predampener is skid mounted with forklift tubing. This allows the equipment to be lifted and repositioned using a forklift.
For applications that require greater mobility, a trailer-mounted option is available.
The choice between skid and trailer mounting can depend on the operating environment and frequency of equipment relocation.
Benefits of a Predampener for Refractory Hydration
A dedicated Predampener can provide several advantages for refractory material preparation:
Controlled moisture addition
Up to 5% moisture capability
Precise hydrostatic predampening
Adjustable water volume
Controlled material output
Up to 12 tons-per-hour processing
Large 3,000-pound hopper
Integrated material feeding
Mixing capability

Supporting Consistent Nozzle Application
The Predampener is designed to prepare gunning materials before they reach the nozzle. By introducing controlled moisture during the predampening process, the equipment supports proper hydration at the application point.
The hydrostatic system and adjustable water bars provide operators with greater control over material conditions, while the high-capacity design supports continuous production.
Selecting a Predampener
When selecting a Predampener for proper refractory hydration, consider the material output required, hopper capacity, moisture-control needs, available electrical supply, and equipment mobility.
The Blastcrete Predampener combines controlled moisture addition with hydrostatic material processing and high-capacity handling.
Its 0-12 tons-per-hour output, 3,000-pound hopper, adjustable water system, and flexible mounting options make it suitable for demanding refractory gunning applications.
