Milling & Packout (B)


The final stage of many API manufacturing processes is a powder sizing or milling process. This process can utilize a wide variety of sizing equipment. The milling process is sometimes integrated into the packout process during the final drying stage, but often this is an stand-alone process. Common challenges with this process are associated with the handling of the dry powders. The transfer and milling process can be very dusty and may require inerting depending on the properties of the powder.

The EHS Drum Inverter with the integrated milling system can reduce an additional handling step and dramatically reduce the airborne dust levels of the operation. By integrating the mill and utlizing our EmptyAssist feature, the milling process can be made much more efficient and ensures that all the product gets removed from the drum.

If you are milling back into a drum or bin, our Mobile Ventilation Sleeve provides a very cost effective dust control solution.

Features of the EHS Solutions mobile slewing drum inverter

Mobile Slewing Drum Inverter

The EHS Drum Inverter features a very robust and portable design that allows operators to lift and position drums above tall applications. Custom options on the Drum Inverter allow it to accommodate a wide variety of applications. A variety of compression cone designs are available to allow the Drum Inverter to be used with a range of drum diameters. The optional empty assist feature addresses the issues associated with powders trapped in the folds of the drum liner during inversion.

The column on this Mobile Slewing Drum Inverter rotates via a slewing bearing, allowing the operator to load a drum in one position and then rotate the machine into position over the discharge point. This allows the Drum Inverter to remain in the same position throughout the charging of multiple drums.

This design features an integrated Flexsift screener at the discharge of the compression cone.



Mobile Ventilation Sleeve

The EHS Ventilation Sleeve provides localized dust extraction to capture airborne dust and vapor. The full perimeter slot design provides 360 degrees of extraction to ensure that the required capture velocity is achieved across the entire opening of the Ventilation Sleeve. Each Ventilation Sleeve is engineered to interface with the equipment it serves.

The EHS Mobile Ventilation Sleeve allows the EHS Ventilation Sleeve to be portable and utilizes a simple linkage design that makes the height adjustable.

The integrated transport cart allows the Ventilation Sleeve to be easily moved from one location to another. A lift-assist mechanism attaches the Ventilation Sleeve to the transport cart, allowing the height of the Ventilation Sleeve to be adjusted.



EHS Solutions - Containment Equipment - Air Filtration Unit

Air Filtration Unit (Supporting Product)

EHS offers a complete line of portable and stationary Air Filtration Units that provide a local HEPA filtration device to serve Local Exhaust Ventilation (LEV) systems. The EHS Air Filtration Unit is designed to meet the utility requirements of multiple EHS Ventilation Sleeves; it is also a good fit for any application with similar extraction utility requirements.

Each system is configured to comply with international electrical standards. The GMP compliant design features a small footprint and noise rating of 76 dBa. Safe Change filters and activated carbon filters for VOC’s are also available.

EHS Air Filtration Units are a cost effective alternative to upgrading house exhaust systems that have become over utilized or where there is a need to prevent the contamination of the house exhaust system ducting.
