Consistent moisture management is an important part of preparing gunning materials for refractory and shotcrete 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 precise material predampening and output control.
Moisture Control Equipment for Gunning Materials
The Blastcrete Predampener provides a dedicated solution for contractors and industrial operators who need reliable moisture control equipment for gunning materials. The machine combines a hydrostatic predampening auger, material feed screw, mixing auger, and water-delivery system to condition material before it reaches the application process.
By controlling water addition during material handling, operators can adjust the predampening process according to their production requirements.
Controlled Material Predampening
The completely hydrostatic design is intended to provide accurate material predampening and output control. The system uses a 9-inch hydrostatic predampening auger to move and condition gunning material.
The machine is designed to add up to 5% moisture. Two solenoid-activated water bars introduce water into the material, while simple water-volume adjustment allows operators to regulate the amount of water being added.
This approach to controlled material predampening can help provide consistent material conditioning for demanding gunning applications.
3,000-Pound Material Hopper
The Predampener features a hopper with a capacity of up to 3,000 pounds and a material feed screw. This provides substantial material storage while supporting a controlled flow into the predampening system.
A mixing auger with a removable rubber enclosure further supports the material-conditioning process. These components work together to provide continuous feeding, mixing, and moisture addition.
Hydrostatic System for Output Control
Hydrostatic operation allows the Predampener to provide precise control over material movement and output. The machine has a stated production capacity of 0–12 tons per hour, making it suitable for a variety of industrial material-preparation requirements.
The combination of adjustable water delivery and hydrostatic material handling gives operators greater control over the predampening process.
Industrial Construction and Handling
The Predampener is skid mounted with forklift tubing, allowing it to be handled and positioned using forklift equipment. Its dimensions are 156 inches × 60 inches × 72 inches, with a listed weight of 2,800 pounds.
The machine is powered by a 20 HP electric motor with disconnect and enclosure. Power options include 240V or 480V, three-phase configurations. A trailer-mounted option is also available.
