Efficient refractory installation depends on proper material preparation, controlled moisture, and consistent application. The right low rebound refractory equipment can help contractors improve material handling and achieve better hydration at the nozzle. A Predampener is designed specifically for this purpose by adding a controlled amount of moisture to gunning materials before application.
The Blastcrete Predampener can 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 control over material predampening and output, making it a practical solution for demanding refractory applications.
What Is a Predampener?
A Predampener is refractory equipment designed to introduce a controlled amount of water into dry gunning materials before they reach the nozzle. This process helps prepare the material for application and can improve hydration consistency during refractory installation.
The hydrostatic design allows operators to control the predampening process and adjust material output according to project requirements. Two solenoid-activated water bars provide simple water-volume adjustment for controlled moisture addition.
For applications where material efficiency and consistent hydration are important, a Predampener can be an important part of the refractory material handling system.
Low Rebound Refractory Equipment
Material rebound can increase waste and reduce application efficiency during gunning operations. Using low rebound refractory equipment with controlled predampening can help address this challenge.
The Predampener is designed to add up to 5% moisture to gunning materials, helping support proper hydration at the nozzle. Consistent moisture preparation can contribute to improved application performance and help reduce unnecessary material rebound.
The goal is to provide operators with better control over the material before it reaches the application point.
Proper Hydration Refractory Equipment
Proper hydration refractory equipment plays an important role in preparing gunning materials for efficient application. The Predampener provides controlled moisture addition through its hydrostatic predampening system.
The unit uses two solenoid water bars, allowing operators to adjust water volume based on the material and operating conditions. This controlled approach helps maintain consistent predampening while supporting proper hydration at the nozzle.
Because moisture requirements can vary between materials and applications, adjustable water delivery provides useful flexibility for refractory contractors.
Key Features of the Predampener
The Predampener is built for industrial refractory applications and includes components designed for reliable material processing and moisture control.
9-Inch Hydrostatic Predampening Auger
The 9-inch hydrostatic predampening auger helps provide controlled material movement and moisture distribution during the predampening process.
Mixing Auger
A mixing auger with a removable rubber enclosure helps mix the material during processing while providing convenient access for maintenance.
Large Material Hopper
The equipment includes a hopper with a capacity of up to 3,000 pounds, along with a material feed screw for controlled material delivery.
Two Solenoid Water Bars
Two solenoid-activated water bars provide adjustable water delivery. Operators can make simple water-volume adjustments to achieve the desired predampening level.
20 HP Electric Motor
The Predampener is powered by a 20 HP electric motor with a disconnect and electrical enclosure. Power configurations are available for 240V or 480V, 3-phase systems.
