The Grieve Corporation‘s No. 864 is a 175°C, natural gas-heated belt conveyor oven currently used for drying gold ore samples at the customer’s facility. Workspace dimensions of this oven measure 1,980-mm wide by 10.7-metres long. The modulating natural gas burner delivers 1,650,000 BTU to heat the oven chamber, while a recirculating blower provides vertical downward airflow to the workload.

This Grieve oven features a 1,525-cm-long open belt loading zone, 10.7-metres long insulated heat zone with recirculated airflow and 305-mm long open belt unloading zone, plus 100-mm insulated walls, aluminized steel interior and exterior.  A 1,830-mm wide, 25 x 25-mm galvanized steel, flat wire conveyor belt with variable speed transports the workload. Side access doors are provided along the length of the workspace to inspect the load and service the heating chamber.

All safety equipment required by IRI, FM and NFPA Standard 86 for gas-heated equipment are provided on this belt conveyor oven, including an exhaust blower.

Controls on No. 864 include a conveyor belt start/stop, digital indicating current proportioning temperature controller, manual reset excess temperature controller, variable SCR drive to control conveyor belt speed, pilot lights to indicate when blower and heat are energized, pushbutton electronic ignition, on-off heat switch and main oven control pushbuttons.  The NEMA 12 control panel is equipped with a lockable fused disconnect switch.
