Efficient refractory gunning requires consistent material preparation and controlled moisture addition. A 20 HP electric refractory predampener provides an integrated solution for processing gunning materials before they reach the nozzle.
The Blastcrete Predampener is designed to add up to 5% moisture to gunning materials to support proper hydration at the nozzle while helping minimize rebound. Its completely hydrostatic system allows precise material predampening and output control, while two solenoid-activated water bars provide simple water-volume adjustment.
20 HP Electric Refractory Predampener
The Blastcrete Predampener is powered by a 20 HP electric motor and includes a disconnect and electrical enclosure.
The available power options are:
240V, 3-phase
480V, 3-phase
The electric drive powers the predampening and material-processing system, providing an integrated solution for industrial refractory gunning applications.
Operators should verify the appropriate voltage and electrical configuration for the intended installation.
Controlled Moisture Addition for Gunning Materials
The Predampener can add up to 5% moisture to gunning materials.
Two solenoid-activated water bars provide controlled water delivery, with simple water-volume adjustment. This allows operators to manage moisture addition according to application requirements.
The equipment is designed to support proper hydration at the nozzle while helping minimize rebound.
Hydrostatic Predampening System
A 9-inch hydrostatic predampening auger provides controlled material processing.
The Predampener's completely hydrostatic design allows precise control over material predampening and output. As gunning material moves through the system, controlled water is introduced through the solenoid water bars.
This integrated process helps prepare material before it reaches the nozzle.
High-Capacity Material Processing
The Predampener provides an output range 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 movement.
The combination of high hopper capacity and up to 12 tons-per-hour output makes the system suitable for demanding industrial refractory applications.
Mixing Auger With Removable Rubber Enclosure
The Predampener includes a mixing auger with a removable rubber enclosure.
The mixing auger helps distribute added moisture through the material during processing. The removable enclosure provides access for inspection and maintenance.
The mixing system works together with the hydrostatic predampening auger to prepare gunning material before nozzle application.
Two Solenoid Water Bars
The Predampener is equipped with two solenoid water bars for controlled moisture addition.
Simple water-volume adjustment allows operators to regulate the amount of water introduced into the gunning material.
The system is designed to add up to 5% moisture, supporting proper hydration at the nozzle while helping minimize rebound.

Supporting Proper Hydration at the Nozzle
The Blastcrete Predampener is designed to add controlled moisture before gunning materials reach the nozzle.
The combination of hydrostatic material processing and adjustable water delivery supports proper hydration at the nozzle and helps minimize rebound.
Operators can adjust water volume while managing material predampening and output through the hydrostatic system.
Selecting a 20 HP Electric Refractory Predampener
When evaluating a 20 HP electric refractory predampener, consider production requirements, hopper capacity, moisture-control needs, electrical supply, equipment dimensions, and mobility.
The Blastcrete Predampener provides a 0-12 tons-per-hour output range, a 3,000-pound hopper, a 9-inch hydrostatic predampening auger, two solenoid water bars, and a 20 HP electric motor.
This combination provides an integrated solution for refractory gunning material preparation.
