Consistent moisture control is important when 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. With hydrostatic material handling, controlled water addition, and a durable construction, this equipment provides an efficient solution for industrial material predampening.

Powerful 20 HP Predampener for Industrial Applications

The Blastcrete Predampener is equipped with a 20 HP electric motor, disconnect, and enclosure. The motor is available in 240V or 480V, three-phase configurations, providing a practical power solution for industrial facilities and material-processing operations.

The 20 HP predampener is designed to work with a hydrostatic predampening system that allows precise control of material movement and output. This can help operators maintain a consistent predampening process while handling substantial quantities of gunning material.

Skid Mounted Predampener for Easy Handling

The equipment features a skid mounted predampener design with integrated forklift tubing. This configuration makes the machine suitable for industrial environments where equipment may need to be positioned or relocated using a forklift.

The skid-mounted construction also provides a stable platform for the predampening and material-feeding components. For applications requiring greater mobility, a trailer-mounted option is available.

Hydrostatic Predampening System

At the center of the system is a 9-inch hydrostatic predampening auger. The hydrostatic design allows operators to control material predampening and output accurately.

The machine can add up to 5% moisture to gunning materials. Two solenoid-activated water bars provide water delivery, while simple water-volume adjustment allows operators to control the amount of water introduced into the material.

Mixing Auger and Material Feed System

The Blastcrete Predampener includes a mixing auger with a removable rubber enclosure and a material feed screw. The hopper can hold up to 3,000 pounds of material.

This combination supports continuous feeding and mixing as material passes through the predampening system. The design is intended for contractors and industrial users who require controlled material preparation before gunning operations.

Production Capacity

The Predampener has an output capacity of 0–12 tons per hour, making it suitable for a range of production requirements. Its combination of a high-capacity hopper, material feed screw, hydrostatic auger, and 20 HP motor provides a complete system for controlled material predampening.

The manufacturer also states that the equipment is recommended by major refractory material manufacturers.
