Cement and Aggregate Applications
Cement and Aggregate facilities are dusty, dirty, humid environments. Sand, gravel, crushed stone and water are in use in many forms throughout the facility. Keeping solid particles and water vapor out of oils and machinery is important.
Mobile equipment such as cranes and shovels are used to move materials around the facility or place them on conveyor systems. They are also used to dig or dredge the sand and gravel from lakes, rivers and streams. Hydraulic systems and gearboxes on the mobile equipment are subjected to dust and humidity continuously. Protecting the oils from water vapor and solid particulates keeps the systems running smoothly.
Bulk material handling terminals load, unload and store the fine and coarse aggregates. The conveyor systems are used to move various materials. Each system is equipped with large drives, gearboxes and bearings that have oil and lubrication reservoirs. Air Sentry® breathers provide protection from airborne dust and moisture.
For extreme conditions, like what can be found on equipment in a cement and aggregate facility, many breathers can be used. The M-Series breathers provide rugged steel housings for the most extreme conditions. The XR-Series combines the strength of the steel base plate with the controlled airflow of check valves in an economical disposable cartridge. For applications where vibration or rough ground isn’t an issue, the X-Series breathers contain two check valves in the top cap to protect the breather and equipment from air ingression unless it’s necessary.
