July 24, 2019 – Grieve has introduced the electrically heated 500º F (~260ºC) No. 1018 three-zone belt conveyor oven, currently used for drying ceramic parts.

Workspace dimensions are 18” wide x 40’ deep x 18” high. There are 180 KW (60 KW per zone) installed in Incoloy-sheathed tubular heating elements, while three 3-HP recirculating blowers (total 12,600 CFM) provide vertical downward airflow to the workload. The oven was split into three sections for shipment.

The unit contains a 12” wide, 1/2” stainless steel flat wire conveyor belt with 1/3-HP motor drive, variable from two to 30 inches per minute with a 30” long open belt loading zone and a 60” long open unloading zone.

This Grieve conveyor oven features four-inch insulated walls, aluminized steel exterior and Type 304, 2B finish stainless steel interior, three independent doors for access to the workspace and three 325 CFM powered forced exhausters. The unit was built to NEMA 12 electrical standards. It has disposable fresh air filters in each zone, including photohelic pressure gauges with alarms.

Controls onboard No. 1018 include SCR power controllers and independent recirculated airflow and temperature controls for each of three 162” insulated heat zones.
