The Rotary Drum Cooler, invented in China, is used for cooling bulk materials like calcined coke and graphite anode materials. It consists of a rotating drum and other parts. It has features like excellent capacity control, high - efficiency cooling, and patented designs. Its working principle involves heat exchange within the rotating drum.
The Rotary Drum Cooler, a remarkable invention from China, has made significant strides in various industries. SONGLING, with its multiple patented technologies, has been at the forefront of this development.
This cooler is designed for cooling bulk materials such as Calcined coke, Semicoke, Needle coke, and Graphite anode materials. It is also applicable in processes like Magnesium reduction, Steel slags, and Manganese reduction.
The structure of the Rotary Drum Cooler is comprehensive. Comprising a rotating drum, material inlet and outlet sections, a cooling water system, and a drive mechanism, it functions effectively. The drum's unique design, with an outside cylinder of membrane pipes and an inside cylinder of tubes along with guide fins, ensures efficient heat transfer from hot materials to cooling water.
The features of this cooler are impressive. It offers excellent capacity control and is insensitive to material size and characteristics. Its highly reliable and efficient cooling is a result of patented designs, including the seal design, roller support design, and water inlet station. It also allows for easy on - line check and maintenance with very low auxiliary power consumption.
The working principle is based on solids entering the rotating barrel and being cooled by fins. The spiral fins lift and convey the solids without mechanical pushing force, minimizing erosion. The solid flow is related to the barrel's rotating speed, which is DCS - controlled by a variable - frequency motor according to bed pressure, enabling automatic adjustment of ash cooling capacity.
