Overview of the Mill Cylinder

The mill cylinder has a diameter of about 9000mm and comprises two halves connected by bolts. Each cylinder weighs nearly 55 tons. Given the large size and weight of the metal component, ensuring machining precision and efficiency became the most significant challenge.

Technical Requirements and Challenges

The cylinder machining project came with high technical requirements:

  1. Flange Verticality: The verticality between the two end flanges needed to be controlled within 0.05mm. This is critical because even a tiny deviation could affect the final assembly and lead to operational instability in the mill.
  2. Runout Tolerance: The runout tolerance was also set at 0.05mm. Runout refers to the deviation of the center of rotation. If it's too high, the mill's performance could be compromised, causing early wear or even failure of the equipment.
  3. Surface Roughness: The surface roughness had to meet a specification of 3.2 microns. A smooth surface is essential for the component's operational efficiency and its interaction with other parts in the mill.
  4. Small Holes Machining: The cylinder features several small holes on both ends and along the body, which had to be machined in one go. Given the precision required for these holes and their close spacing, we needed to ensure accurate positioning and sizing without any inconsistencies.

These strict requirements are not only very demanding for high precision from our equipment but also from the operators. This was our first time machining such kind of mill cylinders, and much of the work involved adapting to new challenges.

Machining Process and Equipment Selection

To successfully complete the project, we carefully planned each step of the machining process and selected the appropriate equipment.

heavy duty machining for ball mill cylinder

1. Machining the Flange Faces — Using the Innse-Berardi 280 Floor Borer

The first step was to machine the flange faces on both halves of the cylinder, ensuring they would align correctly during assembly. For this task, we used the Innse 280 floor borer. This machine offers excellent stability and precision, making it ideal for large components like the mill cylinder.

2. Overall Turning and Drilling — Using the Vertical Lathe

After machining the flange faces, we moved on to the overall turning and drilling of the cylinder. Given the large size of the component, a conventional floor borer was not sufficient. Therefore, we opted for a 22-meter vertical lathe for this part of the process.

3. Precision Inspection and Fine-Tuning

Once the initial machining was complete, we thoroughly inspected the cylinder to ensure all specifications were met. We used a coordinate measuring machine (CMM) to check verticality, runout, and other key tolerances.

Challenges During the Machining Process

  1.  Machining Large Workpieces
    The size and weight of the mill cylinder were the biggest challenges. Especially during turning and drilling, the large workpiece was prone to instability, which could result in deformation. To overcome this, we used custom jigs and fixtures to secure the workpiece and maintain its stability throughout the machining process.
  2. Precision Control
    Maintaining precision was another significant challenge. Small deviations, particularly with the flange verticality, runout, and hole positioning, could affect the assembly and performance of the final product. We addressed this challenge by continuously measuring and adjusting during the machining process to ensure that every parameter was within tolerance.
  3. Adapting to a New Design
    This was our first time machining a two-piece mill cylinder, so we had to adjust to a new design and unfamiliar machining requirements. We prepared by carefully reviewing the blueprints and conducting equipment tests before starting the machining process. Operator training was also crucial to ensure everyone involved was familiar with the process and could handle any unexpected issues.
