Low maintenance, high durability Gear Drive Rotary Kiln

Built for unrivaled durability and dependability across the full range of operating conditions, our Gear Drive Rotary Kiln helps ensure the rotation of the kiln — promoting optimal material flow in all circumstances.

The Gear Drive Rotary Kiln features advanced technology. Controlled by a variable frequency drive, the rotary kiln always operates at the optimal speed for the materials and situation. Additionally, limit switches on the maintenance brake make sure the brake is disengaged when the motor is operating.

The Gear Drive Rotary Kiln can be used by any operation that requires a pyro processing rotary kiln, and functions well with any process. It is required over a friction drive kiln for any kiln with 3 or more supports.

Expect more from your kiln solution, with a reliable, durable, low-maintenance Gear Drive Rotary Kiln from FLSmidth.
