The Koster Keunen Granulator is the first fully functional wax granulator of its type ever developed. Prior to the Koster Keunen Granulator, wax granulation was performed with the use of large prill towers. Such prill towers were typically 80 feet in height. The Koster Keunen Granulator is typically 16 to 20 feet in height and processes approximately 2000 lbs per hour. The Koster Keunen Granulator is composed of prefabricated parts and is easily assembled by the customer on site and can be operated by the customer with a minimum of training. 

Liquid wax is sprayed into a spray chamber and is air cooled. The resulting wax granules are similar to sugar.
