Bartlett-Snow™ Rotary Kilns

Bartlett-Snow™ direct-fired rotary kilns are provided for applications requiring product temperatures to 3000°F / 1650°C and oxidizing or slightly reducing atmospheric conditions. In addition, the process material must tolerate contact with products of combustion and/or the burner flame envelope, as well as reflect a particle size range, specific gravity and shape that allows reasonable gas velocities through the cylinder.

Design features

Bartlett-Snow™ rotary kiln refractory-lined cylinders are supported in two riding rings, each resting on a pair of trunnion rolls. The cylinder is rotated using a girt gear and pinion drive arrangement. Both ends of the cylinder are enclosed by stationary breechings with rotary seals, as required for the application. The feed breeching is refractory-lined and can utilize a feed chute or a variety of feeding mechanisms. At the discharge end, the refractory-lined firing hood is carriage mounted so that it can be rolled back to permit access to the cylinder interior.

Bartlett-Snow™ rotary kilns are provided with automatic temperature, pressure and electrical controls, with burner systems capable of firing natural gas, propane and/or oil. Available in sizes ranging from 24-144 in / 610-3657 mm in diameter with lengths 12 ft to over 100 ft / 3.65 to over 30.48 m.
