Dust Extraction
The integrated Rheo Ventilation Sleeve captures any dust that may be generated by the transfer of dry powders. Additional dust extraction ports can be fitted to capture displaced air in the receiving container. Air flow rates are controlled by manual damper valves.
Vibratory Screener
Using a simple pneumatic turbine vibrator, the screener allows for quick screening of material during various product transfer processes. Several vibrator variations and speed settings allow the system to adapt to various applications, from V-Shell Blender discharge to Drum to Drum Weighing operations.
Options
A variety of options are available for the Rheo Product Screener to ensure the final product meets the application needs.
The following are a selection of some of the options available:
• Bag Disposal Port
• Product Chute
• Bag Landing Table
• Backsplash
• Wall Mount Attachment
• Integrated Bin-Lid
Cleanability
This system is fully wash-down capable and can be quickly disassembled for easy cleaning. The removable cover on the integrated Ventilation Sleeve provides wipe-down access to all surfaces of the sleeve.
Customizable
The Rheo engineering process allows the shape and size of the Product Screener to be customized to fit most applications. The screener can be built to work with any application height. Integrated Ventilation Sleeve diameters of 12 inches to 20 inches can be used with the Product Screener.
Easy Screen Change-Out
Multiple screen mesh sizes are available and can easily be switched out. Should the screener not be needed for a particular operation, the screen can be removed and the device can be used as a simple dust containment control.
Utility
The Product Screener can be connected to any in-house dust extraction system or mobile dust collector/filter system. Utility requirements vary according to the diameter of the integrated Ventilation Sleeve (airflow recommendations shown below).
