Designed to handle the highly abrasive bottom ashes generated by coal-fired boilers. Its high crushing force and unique roll tooth pattern are highly effective for the remaining larger slag falls.

For applications requiring even higher crushing force and more output particle size options than our PowerASH® single-roll grinder.

Efficiently regulates the discharge of material from the Hydrobin dewatering bin once the dewatering cycle is completed.

Provides reliable shut-off operation in pyrites removal systems, bottom ash transport systems, and many other slurry transport applications. Able to handle severe operating conditions.

Provides wear-resistant crushing to pulverize bottom ash material to a suitable transport size. Our grinder rolls are made of hard-as-cast Ni-hard for a longer wear life.

Effectively combines dry fly ash from a silo with water to form a moist mixture. This mixture is readily transferable and transportable with minimal dust emissions. The unit is fully assembled for ease of installation, uses durable materials to lengthen wear life, and is designed with accessible components for easy on-line inspection and maintenance.

Uses wastewater from a flue gas desulfurization (FGD) system for blending into the ash for processing. Provides a unique solution for ELGs. It not only minimizes the use of plant process water for ash processing, but also provides a beneficial use for FGD wastewater.

Used primarily for the transfer of fly ash or other dry, free-flowing, granular solids, the Style IV airlock design is available for both pressure and vacuum system applications. In a pressure conveying system, solids are transferred from an overhead collection point into a receiving chamber by utilizing a set of isolation gates above and below the chamber. In vacuum conveying systems, the filter collector is located above the ash storage silo. The A-S-H airlock adjusts the pressure zones between the filter collector and the silo without requiring a break in the vacuum level for continuous operation.

Suitable for regulating dry, free-flowing fly ash material into a transport system. Designed for changing or harsher operating conditions, including stickier and more abrasive ash, our Advantage Series valves encourage ash flow and minimize wear by utilizing hardened components for high-abrasion zones. They are available for lateral feed vacuum conveying systems and as a direct replacement for UCC® Tiger™ valves.

Used in pressure systems for airlock equalization and in vacuum systems for collector equalization applications, the Style Ill equalizer valve is compact, lightweight and affordable.

Replacement wear part upgrade provides improved wear life, easier maintenance and increased sealing force for greater material head support compared to Style I airlock components.

Multiple chamber design allows for continuous ash collection—even when ash is being loaded into the storage silo. The CycloASH 60 collector offers easy maintenance, extended wear life and superior sealing.

Designed specifically to feed ash into dilute-phase vacuum systems on a batch basis. The Type-H material handling valves are durable, efficient and can handle the most severe operating environments.

Refurbishment and maintenance kits for Allen-Sherman-Hoff® Style I and IV airlocks, as well as upgrade kits to convert Style I airlocks to Style IV design, these kits come complete with everything needed to refurbish your airlock to original operating condition.

Feature wear-resistant tiled ceramic liners that are custom fit to an outer steel shell for optimum performance and long wear life. With applications in both hydraulic and pneumatic conveying systems, they are recommended for high-abrasion areas such as elbows, tees, laterals, inlet regions and transfer points.

Designed for vacuum systems that convey highly erosive ashes. Made of a chrome-iron alloy, the fitting bodies are available in two grades depending on hardness requirements.

Standard on all pressure systems, both hydraulic and pneumatic. They are specially designed to withstand the abrasive characteristics of many ashes.
