Product sizing and milling is a frequent process in the manufacturing process. This often requires drum be emptied into the infeed chute of the mill and then the powder is collected in a receiving drum. This process is labor intensive and can create high levels of airborne dust, often exceeding protection factor of operator PPE. Rheo has many options to improve both the safety and speed of this process. Our Variable Height Drum Tipper package offers a fast and easy to use transfer process that positions the drum above the mill opening. A Ventilation Sleeve can be place into the mill opening to provide local dust extraction to reduce airborne dust. This system offer access to the drum liner to assist in the flow of powders that have poor flowability. The Mobile Ventilation Sleeve can be used to capture airborne dust during the emptying process of the mill.
