Major - Fixed Axis Rotary Furnaces

Applications

• Copper Lead or Zinc Smelting
• Gold Smelting
• Aluminium Dross or Scrap Recycling

Benefits

• Traditional Process
• Economic furnace configuration

Equipment Description

The furnace comprises a refractory lined cylinder, swing aside charge door, rear mounted burner and flue, rotary cradle and roller bearings, stationary floor mounted support, fixed fume hood and control cabinet.

Furnace Construction

Charging occurs through an opening in the front of the furnace. The liquid metal discharge occurs through a pour spout mounted in the mid section of the main refractory lined cylinder. When the charge door is closed the front section is a close fit to the main rotating body thus leakage of the flue gases during normal operation is minimised.

Refractory Lining

The refractory lining is of a high quality, abrasion resistant brick and castable, backed up with high density insulation board. The charge door is lined with a dense hot face castable and an insulating backup.

Electrical Cabinet

The electrical control cabinet has an environmental rating of IP55 and is engineered to be mounted either adjacent to or remotely from the furnace. The electrical battery limit is the cabinet mounted electrical isolation device.

Combustion System

The fuel train components have an environmental rating of IP54. The combustion air blower is fitted with noise attenuation on the inlet to reduce noise levels to 83 dBa at 1 metre.

Safety

Floor mounted personnel protection guarding can be provided which are engineered to the Australian Standard and are adjacent to moving parts outside frame support and around hot areas. Guards are provided around the mechanism pinch points, and beside the furnace on each side, protecting personnel from the door opening.
