Proper moisture control is an important part of preparing gunning and shotcrete materials for efficient application. The Blastcrete Predampener is designed as reliable shotcrete material dampening equipment for operations that need controlled moisture addition, consistent material feeding, and improved hydration before material reaches the nozzle.
With the ability to add up to 5% moisture to gunning materials, the Predampener helps provide proper hydration at the nozzle while minimizing rebound. Its hydrostatic system allows operators to control material predampening and output for demanding refractory and shotcrete applications.
What Is Shotcrete Material Dampening Equipment?
Shotcrete material dampening equipment introduces a controlled amount of moisture into dry material before the material is applied through a shotcrete or gunning system. Consistent moisture addition can help improve material preparation and support proper hydration during application.
The Blastcrete Predampener uses a 9-inch hydrostatic predampening auger and two solenoid-activated water bars. Water volume can be adjusted to help operators maintain the desired moisture level for the material being processed.
Blastcrete Predampener for Refractory Concrete Equipment Applications
For contractors and industrial facilities seeking dependable refractory concrete equipment, the Predampener provides an integrated solution for material feeding, mixing, and moisture addition.
The unit features a hopper with a material feed screw and a capacity of up to 3,000 pounds. The mixing auger is equipped with a removable rubber enclosure, while the hydrostatic predampening system provides controlled material processing.
This configuration makes the Predampener suitable for refractory material preparation and other applications where consistent moisture management is required.

Controlled Moisture Addition
One of the primary advantages of the Predampener is its ability to add up to 5% moisture to gunning materials. Controlled dampening helps prepare the material for proper hydration at the nozzle and can contribute to reduced rebound during application.
The hydrostatic design allows precise predampening and output control. This gives operators greater control over material preparation compared with uncontrolled moisture addition.
High-Output Material Processing
The Predampener has an output capacity of 0–12 tons per hour, making it suitable for industrial operations requiring continuous material preparation.
Its 3,000-pound hopper provides substantial material capacity, while the material feed screw helps move material through the system at a controlled rate.
For large refractory and shotcrete operations, this combination of capacity and controlled dampening can help streamline material preparation.
Durable Industrial Construction
The Predampener is built as skid-mounted refractory concrete equipment, with forklift tubing incorporated into its design for handling and positioning.
The machine measures:
Length: 156 inches
Width: 60 inches
Height: 72 inches
Weight: 2,800 pounds
The skid-mounted configuration allows the equipment to be positioned using suitable material-handling equipment, while a trailer-mounted option is also available.
Electrical Power Options
The Blastcrete Predampener uses a 20 HP electric motor and is available for:
240V, three-phase power
480V, three-phase power
The appropriate power configuration can be selected according to the requirements of the installation.
Why Choose a Predampener for Shotcrete and Refractory Work?
Consistent material moisture is important when preparing dry gunning materials for application. Excessive or insufficient moisture can make material preparation less consistent.
The Blastcrete Predampener is designed to address this requirement by combining controlled water addition with material feeding and mixing. Its hydrostatic predampening system provides operators with a practical method for controlling moisture and material output.
For contractors working with shotcrete, refractory materials, and related applications, using dedicated shotcrete material dampening equipment can make material preparation more controlled and repeatable.
