Consistent moisture addition is essential when preparing dry gunning materials for refractory and related applications. The Blastcrete Predampener is equipped with a hydrostatic predampening auger designed to provide controlled moisture addition and material output.
Featuring a 9 inch predampening auger, the Predampener combines material feeding, mixing, and water addition in one industrial system. It is designed to add up to 5% moisture to gunning materials to support proper hydration at the nozzle while helping minimize rebound.
What Is a Hydrostatic Predampening Auger?
A hydrostatic predampening auger is designed to move and process material while allowing controlled moisture to be introduced during the material preparation process. Unlike a basic material conveyor, a predampening system combines controlled material movement with water addition.
The Blastcrete Predampener's hydrostatic system allows precise control of material predampening and output. This can help operators maintain a more consistent material preparation process.
9 Inch Predampening Auger
The Blastcrete Predampener features a 9 inch predampening auger specifically designed for industrial gunning material preparation.
The auger works as part of the complete Predampener system, which includes a material feed screw, mixing auger, hopper, and two solenoid-activated water bars. Water volume can be adjusted to control the amount of moisture introduced into the material.
The 9-inch auger provides a substantial processing path for moving and predampening material while maintaining controlled output.
How the Predampening System Works
The Predampener is designed to combine several stages of material preparation:
Material Loading – Gunning material is placed into the hopper, which can hold up to 3,000 pounds.
Material Feeding – A material feed screw moves the material into the processing system.
Moisture Addition – Two solenoid-activated water bars introduce controlled water into the material.
Predampening – The 9-inch hydrostatic predampening auger processes the material as moisture is added.
Mixing – A mixing auger helps distribute moisture through the material.
Controlled Output – The hydrostatic system allows operators to control material predampening and output.
Up to 5% Moisture Addition
The Blastcrete Predampener can add up to 5% moisture to gunning materials. Controlled moisture addition is intended to support proper hydration at the nozzle and help minimize rebound during application.
The system's water volume adjustment provides operators with a practical way to regulate moisture according to the material and application requirements.

Benefits of Hydrostatic Predampening
A hydrostatic predampening system provides several practical advantages for material preparation:
Precise Moisture Control
The adjustable water system allows controlled water addition rather than relying on uncontrolled moisture introduction.
Controlled Material Output
The hydrostatic design provides precise predampening and output control.
Integrated Processing
Material feeding, moisture addition, and mixing are combined into one system.
Reduced Material Rebound
The Predampener is designed to help provide proper hydration at the nozzle with minimal rebound.
Industrial Capacity
With output of up to 12 tons per hour and a hopper capacity of up to 3,000 pounds, the equipment is designed for demanding material preparation operations.
Why Choose a 9 Inch Predampening Auger?
The auger is a central component of the Predampener's material-processing system. A 9 inch predampening auger provides the physical processing mechanism needed to move and predampen material while the water system introduces controlled moisture.
For operations requiring consistent gunning material preparation, the combination of a hydrostatic auger and adjustable water delivery provides a controlled approach to material conditioning.
