An improved planetary cooler design that offers an ideal cooling experience
FLSmidth’s Unax Cooler is a planetary cooler that offers an improved design and much simpler method of cooling materials. With its fewer parts, uncomplex functions, and durable features, it aims to optimise your material processing experience.
The Unax Cooler offers an improved planetary cooler design
Despite the improvements of modern grate cooler technology, it is crucial to have a cooling system that offers better affordability. That’s why FLSmidth has developed the Unax Cooler, a planetary cooler that keeps simplicity, durability, and reliability as top priorities.
With installations dating back to 1967, we have used our expertise and experience to create a new generation of internal fittings that improve on older versions of the Unax Cooler. The rising costs of energy and labour combined with the development of more suitable materials and casting techniques both necessitate and enable better designs of planetary cooler internals, which is exactly why the Unax Cooler aims to be more affordable than other coolers on the market.
A planetary cooler is attached rigidly to a rotary kiln and rotates with it. This is unlike a rotary cooler, which is attached at a level lower than the kiln, resulting in higher maintainability costs, as the kiln itself needs to be positioned higher than the cooler on expensive foundations. There are more moving parts in a rotary cooler which can increase maintenance costs compared to a Unax Cooler which is attached to the kiln meaing only one drive system.
With its improved design, our Unax Cooler is bound to produce satisfactory results.
FEATURES
Features that increase lifespan and boost equipment reliability
The improved design of our Unax Coolers is a result of the numerous features that have been added, which have enhanced the durability, reliability, and functionality of the equipment overall.
Breaker lifters
Breaker lifters in the transition zone between the ceramic cam lining and the steel lifter zone reduce lump size in the cooler, which softens clinker impact on lifters and wear plates in the subsequent zones, reducing the risk of corrosion damage.
Improved lifter profile design
The edges of the lifters have been reinforced and the termination angle chosen lowers the effect of clinker impact, resulting in less wear-and-tear.
Improved cast wear plates
The wear plates overlap, protecting the cooler shell against excessive temperatures and wear. The loose wear plate design eliminates the risk of mechanical stresses, leading to more reliable equipment.
Dam rings
The dam rings in the cooler improve the retention time in the cooler and dramatically reduce the abrasion and impact on lifters and wear plates. Dam rings are flexible and can be placed in various places in the cooler to improve cooler efficiency, resulting in a more effective and durable product.
