A gunning material predampener is designed to add controlled moisture to compatible dry gunning materials before they reach the application nozzle. The Blastcrete Predampener is engineered to add up to 5% moisture to gunning materials to support proper hydration at the nozzle while helping minimize rebound.
For refractory contractors and industrial users, consistent material preparation can be an important part of achieving reliable gunning performance. The Blastcrete Predampener uses a completely hydrostatic system to provide precise predampening and output control.
What Is a Gunning Material Predampener?
A gunning material predampener is a material-processing machine that introduces a controlled amount of water into dry gunning materials before application.
The Blastcrete Predampener combines a material hopper, feed screw, hydrostatic predampening auger, mixing auger, and water-delivery system.
The equipment is designed to add up to 5% moisture, helping prepare compatible gunning materials for proper hydration at the nozzle.
The required moisture level depends on the material and application, so operators should follow the recommendations provided by the material manufacturer.
Refractory Material Predampener
A refractory material predampener is particularly useful where controlled moisture addition is required during refractory material preparation.
The Blastcrete Predampener provides hydrostatic material predampening and adjustable water volume through two solenoid-activated water bars.
This configuration allows operators to manage moisture addition while controlling material output.
For refractory applications, controlled predampening can help create more consistent material conditions before the material reaches the nozzle.
Blastcrete Predampener for Gunning Materials
The Blastcrete Predampener is designed specifically around controlled gunning-material preparation.
Its major components include:
9-inch hydrostatic predampening auger
Mixing auger
Removable rubber enclosure
Material feed screw
Up to 3,000-pound hopper
Two solenoid water bars
20 HP electric motor
Electrical disconnect and enclosure
Skid mounting with forklift tubing
Together, these components provide a dedicated system for controlled material feeding, moisture addition, and predampening.
Hydrostatic Predampening System
The completely hydrostatic design is one of the defining features of the Blastcrete Predampener.
Hydrostatic operation allows precise control of the predampening process and material output.
For contractors handling refractory and other compatible gunning materials, this can help provide greater consistency in material preparation.
The water system also allows operators to adjust water volume according to the requirements of the material and application.
9-Inch Hydrostatic Predampening Auger
The Blastcrete Predampener includes a 9-inch hydrostatic predampening auger.
The auger is designed to move material through the predampening system while controlled moisture is introduced.
Its configuration supports continuous material processing for suitable industrial and refractory applications.
Two Solenoid Water Bars
The machine is equipped with two solenoid-activated water bars.
These water bars provide controlled water delivery into the gunning material. Simple water-volume adjustment allows operators to manage moisture addition according to the material requirements.
The Predampener can add up to 5% moisture to compatible gunning materials.
Mixing Auger and Rubber Enclosure
A mixing auger is incorporated into the system to assist with material movement and moisture distribution.
The mixing assembly includes a removable rubber enclosure, providing access for appropriate inspection and maintenance.
Regular maintenance should be performed according to the applicable equipment and material recommendations.
3,000-Pound Capacity Hopper
The refractory material predampener features a hopper with a capacity of up to 3,000 pounds.
A material feed screw moves material from the hopper into the predampening system.
The large hopper capacity can support continuous material handling for suitable high-volume applications.
20 HP Electric Motor
The Blastcrete Predampener is equipped with a 20 HP electric motor, disconnect, and electrical enclosure.
Power options include:
240V, 3-phase
480V, 3-phase
The appropriate electrical configuration should be selected according to the available power supply and installation requirements.

This configuration can be considered for operations where the equipment needs to be transported between suitable work locations.
Before selecting a trailer-mounted configuration, contractors should consider equipment weight, dimensions, towing requirements, jobsite access, and applicable transportation requirements.
Choosing a Gunning Material Predampener
When selecting a gunning material predampener, contractors should consider several factors.
Material Compatibility
Confirm that the equipment is suitable for the specific gunning or refractory material.
Moisture Requirements
Determine the recommended moisture level from the material manufacturer.
