Types of Mills

In general, wet grinding mills are suitable for rubber linings. The wide operational scope of the company ranges from autogenous mills fed by coarse materials to ball mills employed for very fine grinding processes.

Rubber lining can be used for dry grinding as well. However, in this case, it is even more important to determine the appropriate formulation for the process and to monitor the mill’s grinding conditions and temperature constantly

Rubber lining applications have shown reliable results in the following mills:

  • Autogenous Mills
  • Semi-Autogenous Mills
  • Rod Mills
  • Ball Mills
  • Pebble Mills
  • Cylpeb Mills
  • Cone Mills
  • Batch Mills
  • Washing trommels with customized designs

Comparison Between Rubber and Steel Linings

Rubber linings are superior to steel linings in many respects. The core advantages are listed below.

ACTIVE LIFESPAN
The active lifespan of rubber lining and lifter bars is 1-5 times longer compared to steel. Since the wear of rubber linings is lower, the mill reaches a higher grinding capacity and performance per unit time. Tests have shown that while steel lifterbars located at the most worn-out parts of the autogenous mill ran for 600 hours and process 75,000 tons of ore before their active lifespan ends, rubber lifterbars installed at the same location ran for a minimum of 2700 hours and process 390,000 tons of ore.
WEIGHT
Rubber mill linings are nearly 75% lighter than steel linings, thus failures in mill bearings and the lubrication system are being minimized.
SEALING
The holes of steel lining and lifterbars are susceptible to frequent deformation. Resulting leaks can infiltrate down to mill bearings and cause damage. Rubber linings- on the contrary- provide perfect sealing without deformation.
NOISE DAMPING
Thanks to the rubber’s capability of isolating and absorbing noise, they provide a healthier working environment.
COST-EFFECTIVENESS
Unit costs (ground ore per per ton) for rubber linings are always lower than steel linings. The following list shows operating hours determined by FKK for various types of linings and various types of mills.

Advantages of
Rubber Mill Linings

  • Adaptation to chilling conditions
  • Wear resistance and structure
  • High usability factor
  • Improved working environments due to reduced noise levels
  • Safe operation
  • Corrosion-resistant
  • Resistance to temperatures up to 80°C
  • Lightweight
  • Fast, easy and safe assembly
  • Reduced unit cost for grinding (compared to steel)

Rubber & Polyurethane Screens

We offer customized solutions for specific customer needs.

Advantages

• Resistance against wear and impact.
• High sieving capacity.
• Easy assembly, easy replacement.
• Better working conditions, silent operation.
• No damage to screened materials.
• Low sieving cost.
• Much longer active lifespan compared to wire and sheet screens.
• Polyurethane screens are flexible, they avoid the retention and sticking of work materials, and screen holes are tapered downwards preventing obstruction and allowing the self-cleaning of the screen.
• Thanks to the smooth sieving surface, screened materials are equally distributed on the surface.

Dry and wet applications

• Ore
• Sand and pebble
• Crushed stone
• Sinter
• Pellet
• Coke
