Rotary Dryers – Standardised drying for a wide range of materials

In today’s fast-paced industry, you need solutions that are flexible and and standardised. That’s what you get with FT Series Rotary Dryers from FLSmidth. 

When you’ve got goals to meet, the last thing you want is to get stuck waiting on your equipment. But given that every mining operation is unique, sometimes finding the right equipment to fit for your business can be extremely difficult. And when to comes to drying and processing your valuable raw materials, not having the right equipment solutions can grind your entire process down to a halt — decreasing throughput and putting a chokehold on your revenue.

FLSmidth Standardised Rotary Dryer technology to match your materials 

Drive components

  •  Gear and pinion are reversible so that both flanks of the teeth can be utilised for longer life.
  • Forged pinion mounted on an extended reducer shaft for sizes from 3.0 to 3.8 m diameter. Forged pinion with integral shaft for sizes larger than 3.8 m diameter.
  • Automatic gear and pinion spray lubrication system.
  • Fully enclosed gear guard for maximum protection.
  • Grease lubricated spherical roller support bearings designed for 80,000 hour of L10 life.



Dryer shell and internals

  • Shell is fabricated from ASTM A-36 carbon steel. Riding ring sections are made of heavier plate than the balance of the shell
  • Internal lifters shower the material for maximum drying and heat transfer. The internals (starting from the feed end) consist of; feed advancing spirals to minimise back spilling, straight lifters bolted to angle brackets which are welded to the shell, and a section of bare shell at the discharge end to minimise dust entrainment.
  • Overlapping spring plate seals on both ends of the dryer minimise air infiltration.
  • Support rollers are made of high-grade forged steel and are integral with the shafts.
  • Grease lubricated spherical roller support bearings are designed for 80,000 hours of L10 life.
  • Full thrust is included. The downhill thrust roller is designed to take the full downhill thrust.
