Description

Variable Diameter Rotary Kiln

Variable diameter rotary kiln and drift diameter rotary kiln concept are two relative concepts. Variable diameter rotary kiln refers to restore the segment length by adjustable based on drift diameter concept. Variable diameter rotary kiln has been developing rapidly over the past two decades and especially in the past *0 years,variable diameter rotary kiln has been widely used in many fields. In particular,a major success has been achieved in the field of calcined ceramic sand, active lime, acid calcium powder.

The larger diameter of variable diameter rotary kiln is in favour of burning fuel completely during calcination restore,while the smaller diameter maintains a more effective energy-saving of *0% than the traditional path of rotary kiln during the preheating section.Based on the same output, Variable diameter rotary kiln is more low-cost and refractory-saving is more efficient,compared with drift diameter rotary kiln.

Variable Diameter Rotary Kiln Technology Characteristics

1.Kiln is made of high-quality carbon steel and alloy steel sheet and and is a A special automatic welding equipment.

2.Tires, wheel and pen gears are cast from alloy cast steel.

3.Sliding bearings adopt bearing with large gap and no scrapingbushing.

4.Transmission mechanism is driven by hard tooth surfaced reducer,flexible membrane coupling and a direct current motor.

5.Application of thrusting the roller by using hydraulic system.

6.Kiln head and end are with self-tight sealing respectively by use of scales-folding and gas container.

7.slow driving system is provided.
