The Blastcrete Predampener is designed to provide controlled moisture addition to gunning materials before they reach the application nozzle. By adding up to 5% moisture, the Predampener helps support proper hydration at the nozzle while minimizing material rebound.

For refractory and other compatible gunning applications, consistent material moisture can be an important part of achieving reliable application performance. The Blastcrete Predampener uses a hydrostatic design to provide precise predampening and output control.

What Is a Predampener?

A Predampener is material-processing equipment designed to introduce a controlled amount of moisture into dry gunning materials before application.

The Blastcrete Predampener is specifically designed to add up to 5% moisture to compatible gunning materials. Its hydrostatic predampening system allows operators to control material output and water addition.

This controlled process can help provide more consistent material conditions at the nozzle and reduce unnecessary rebound during suitable gunning operations.

Blastcrete Predampener for Gunning Materials

The Blastcrete Predampener combines a large material hopper, feed screw, hydrostatic predampening auger, mixing auger, and solenoid-activated water bars into one skid-mounted system.

The machine is designed for applications where controlled moisture addition and consistent material feeding are important.

Its output capacity is rated from 0 to 12 tons per hour, providing a wide operating range for different production requirements.

Hydrostatic Predampening System

One of the key characteristics of the Blastcrete Predampener is its hydrostatic predampening system.

The hydrostatic design allows precise control of material predampening and output. Water is introduced through two solenoid-activated water bars, with simple water-volume adjustment available to the operator.

This configuration helps provide controlled moisture addition rather than relying on uncontrolled water delivery.

9-Inch Hydrostatic Predampening Auger

The Blastcrete Predampener features a 9-inch hydrostatic predampening auger.

The auger works with the material-feeding and mixing components to move gunning material through the predampening process.

The large auger configuration is designed for continuous material handling while providing controlled moisture addition.

Mixing Auger With Removable Rubber Enclosure

A mixing auger is incorporated into the Predampener to assist with material movement and moisture distribution.

The system includes a removable rubber enclosure, providing a practical configuration for equipment access and maintenance.

Regular inspection and maintenance should be performed according to the applicable equipment recommendations.

3000-Pound Capacity Hopper

The Blastcrete Predampener is equipped with a hopper capable of holding up to 3,000 pounds of material.

A material feed screw moves the gunning material from the hopper toward the predampening and mixing system.

The large hopper capacity can support continuous material handling for suitable industrial applications.

Two Solenoid Water Bars

The Predampener incorporates two solenoid-activated water bars.

These water bars provide controlled water delivery during the predampening process. The water volume can be adjusted to achieve the required moisture addition for the material and application.

The system is designed to add up to 5% moisture to compatible gunning materials.

20 HP Electric Motor

The Blastcrete Predampener is powered by a 20 HP electric motor.

Available power configurations include:

240V, 3-phase
480V, 3-phase

The machine also includes a disconnect and electrical enclosure.

Before installation, users should verify that the selected electrical configuration is appropriate for the available power supply and installation requirements.

Predampener for Refractory Applications

Predampening equipment can be useful in refractory material applications where controlled moisture addition is required before nozzle application.

The Blastcrete Predampener is designed to add moisture to gunning materials to support proper hydration at the nozzle and help minimize rebound.

Because material characteristics vary, users should confirm compatibility and recommended moisture levels with the applicable material manufacturer.
