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. By integrating an inline mill into our Drum Inverter system, a handling step can be removed from the process. A mobile ventilation Sleeve can be used to provide local dust extraction at the screener discharge. This package dramatically improves the operator experience and reduces airborne dust during this process. This system also reduces cleaning time and cross contamination as it prevents dust from migrating throughout the process suite.
