General Description and Function: RV-D6B
The RV-D6B is a automatically fed milling machine bounded on top by a infeed rotary valve.
The milling chamber which contains the rotor assembly and discharges milled product
through the bottom of the chamber by a discharge rotary valve. Typically, a user supplied
drum or other product receiver is located below the milling chamber to collect the milled
product. Often, a breathable dust bag is attached to the base of the mill chamber and top of
the receiving drum to contain product dust as milling is underway.
The operator controls can be located on the machine cabinet with electrical circuits, and
control devices located within the cabinet base. The machine can also be supplied with a
remote control enclosure. Normally, the machine is supplied with 15 feet (~ 4.5 meters) of
power cable which the customer will connect to their power supply.
Safety grid bars are typically located at the entry to the feed throat and discharge of the mill
chamber to prevent operator contact with rotating elements of the machine. If rotary valves
are provided, the safety grid bars will be provided in the inlet and outlet transitions. These
transitions will have safety sensors to detect their presence. The rotor will not turn unless
this safety circuit is positively contacted.
