Consistent material preparation is essential for refractory and gunning applications where controlled moisture and material flow are important. The Blastcrete Predampener combines a mixing auger, material feed screw, hydrostatic predampening system, and controlled water delivery to provide an integrated solution for preparing gunning materials.
Designed to add up to 5% moisture to gunning materials, the Predampener helps support proper hydration at the nozzle while minimizing rebound. Its hydrostatic design provides precise control over material predampening and output.
What Is a Mixing Auger Predampener?
A mixing auger predampener is designed to combine material movement, mixing, and controlled moisture addition during the preparation of gunning materials.
The Blastcrete Predampener features a mixing auger with a removable rubber enclosure. Working together with the 9-inch hydrostatic predampening auger, the mixing system helps process material as controlled moisture is introduced.
This integrated approach can help operators maintain more consistent material preparation before the gunning material reaches the application system.
Material Feed Screw for Controlled Feeding
The Predampener includes a material feed screw located beneath its hopper. The hopper can accommodate up to 3,000 pounds of material, providing substantial capacity for industrial material preparation.
The material feed screw moves material from the hopper into the processing system, where it passes through the predampening and mixing stages.
Controlled material feeding is particularly useful when consistent output and moisture addition are important to the application process.
How the Blastcrete Predampener Works
The Predampener combines several material-processing functions into one system:
Loading: Gunning material is placed into the large-capacity hopper.
Feeding: The material feed screw moves material from the hopper into the processing area.
Water Addition: Two solenoid-activated water bars introduce controlled moisture.
Predampening: The hydrostatic auger processes the material while moisture is added.
Mixing: The mixing auger helps distribute the added moisture throughout the material.
Output: The hydrostatic system provides controlled predampening and material output.
Controlled Moisture Addition
The Blastcrete Predampener can add up to 5% moisture to gunning materials. Two solenoid water bars provide adjustable water delivery, allowing operators to control the amount of water introduced into the material.
The purpose of this controlled predampening is to support proper hydration at the nozzle and help minimize rebound during application.

Benefits of a Material Feed Screw
A material feed screw plays an important role in maintaining a controlled flow of gunning material from the hopper into the processing system.
With the Blastcrete Predampener, the material feed screw works with the hydrostatic predampening auger and mixing auger to create a continuous material preparation process.
This integrated arrangement can help operators manage:
Material feeding
Moisture addition
Material mixing
Predampening
Output control
