Rotary Cooler Manufacturer

What is a Rotary Cooler ?

A Rotary Cooler is a rotating cylindrical drum where hot material is gently tumbled and cooled using ambient or conditioned air. This process enables a uniform and gradual reduction in product temperature, preventing thermal degradation, agglomeration, or packaging issues. Rotary coolers are typically used downstream of rotary dryers, kilns, or calciners for seamless integration in continuous production lines.
