Consistent material preparation is essential for efficient refractory and gunning applications. 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 hydrostatic operating system provides controlled predampening and output for demanding material-processing applications.
High Capacity Predampener for Industrial Applications
The Blastcrete Predampener is built to handle substantial volumes of gunning material. With an output capacity of 0–12 tons per hour and a hopper capable of holding up to 3,000 pounds, this high capacity predampener is designed for continuous industrial material preparation.
A material feed screw moves material from the hopper into the predampening system, while the 9-inch hydrostatic predampening auger helps provide controlled material movement and conditioning.
Variable Output Predampener for Controlled Processing
The hydrostatic design allows the machine to provide precise material predampening and output control. This makes the Predampener a practical variable output predampener for applications where material flow and moisture addition need to be managed consistently.
The system is designed to add up to 5% moisture to gunning materials. Two solenoid-activated water bars provide water to the material, with simple water-volume adjustment for controlling the amount of moisture introduced during processing.
Hydrostatic Predampening Auger
A key component is the 9-inch hydrostatic predampening auger. The auger works with the material feed screw and mixing system to condition material as it moves through the machine.
Hydrostatic operation provides controlled material handling and allows operators to adjust the output according to production requirements. This can be useful for contractors and industrial facilities handling different quantities of gunning material.
3,000-Pound Hopper and Mixing System
The Predampener incorporates a hopper with a capacity of up to 3,000 pounds. A material feed screw provides controlled feeding into the predampening system.
The machine also features a mixing auger with a removable rubber enclosure. Together, these components support continuous material feeding, mixing, and moisture addition.
Built for Industrial Material Preparation
The Predampener is skid mounted and equipped with forklift tubing for equipment handling. The manufacturer states that the machine is recommended by major refractory material manufacturers.
Its combination of high material capacity, adjustable water delivery, hydrostatic predampening, and variable output makes it suitable for demanding refractory and gunning material preparation environments.
