Cement Silo Dust Collector

The RH Cement Silo Dust Collector is installed directly on top of a powder storage silo. Its main purpose is to control airborne dust generated during pneumatic conveying, bulk filling and powder storage.

When powder is pneumatically transferred into a silo, the incoming material and conveying air create positive pressure inside the vessel. Instead of sending this dusty air through a long duct to a remote collector, the silo-top unit allows the air to pass directly through its filtration section. Dust is retained while air is released from the silo, helping reduce dust leakage around the silo cover, manhole and other openings.

The operating process mainly consists of filtration and cleaning cycles. Pulse-jet cleaning or mechanical vibration structures can be selected according to the equipment configuration.

Filter media selection is a key part of specifying a Cement Silo Dust Collector because storage materials can differ significantly in temperature, particle size, moisture and static behavior.

Available options in the supplied information include standard-temperature polyester, high-temperature glass fiber for conditions up to 260°C, antistatic media, water- and oil-repellent media, and PTFE membrane media. Antistatic configurations can be considered for powders such as coal powder and aluminum powder, while PTFE membrane media can be selected for very fine or adhesive dust.

Applications are not limited to cement. The equipment can also be used on fly ash, mineral powder, limestone powder, dry-mix mortar, calcium carbonate, talc, resin powder, pigment, fertilizer and plastic-pellet silos. Other listed materials include graphite powder, lithium iron phosphate, lithium carbonate, flour, starch, grain, feed powder, slag powder, metal mineral powder, foundry sand, glass, ceramic and lime powder.
