For over 40 years our engineering department has collected data on behavior and performance of the components of dozens of cement mills in the 1000 to 3600 kW range. Vibration readings have been taken on main moving parts and their relevant supporting structures; in addition, the status of analyzed elements and any problem arising have been recorded.

Such readings have been repeatedly taken at preset intervals so as to create a comprehensive data base. Recently, we set up powerful design workstations and installed dedicated software packages for the finite-element method calculation. By using these packages, we can analyze the critical components of machines of our own design as well as other machines.

ABS offers a variety of MGS Girth Gear designs, each engineered to meet the specific demands of different industrial applications. The choice of design depends on factors such as load capacity, operational environment, and maintenance needs. Below are the primary Girth Gear designs available from ABS:

• T Section Design: Known for its robust construction, the T-section design is commonly used in applications where high torque and load-bearing capacity are required. Its simple and strong structure ensures durability and long service life, making it ideal for heavy-duty applications such as kilns and mills.
• Y Section Design: The Y-section design provides enhanced stability and load distribution. This design is typically used in systems that require precise alignment and smooth torque transmission, reducing wear and improving operational efficiency. It’s suitable for high-stress environments like rotary furnaces and material handling systems.
• Multiple Segments Design: This design features multiple segments, allowing for easier installation, maintenance, and transportation. The multiple segments design is perfect for large, complex systems where modularity and ease of maintenance are key, such as in mining and cement plants.
• Kiln and Rotary Furnace Applications: ABS Girth Gears are specifically designed for kilns and rotary furnaces, where continuous operation, high-temperature environments, and heavy loads are typical. These gears ensure efficient power transmission and minimize wear, even under extreme conditions, ensuring reliable performance and extended equipment life.
