Cooling Machine A cooling machine is regularly used for cooling fine chemical materials in building material production, metallurgic and chemical industries, cement production lines, and compound fertilizer production lines, and more. It is applicable for cooling materials like slag, limestone, coal powder, and clay, etc. Working Principle: As a kind of heat exchange equipment, a cooling machine utilized cool gas or cool water as medium, to cool hot materials. Meanwhile, cooling equipment is able to make full use of the exhaust heat, thus improving the thermal efficiency of a kiln. Applications: Our cooling machine is regularly used in compound fertilizer production lines, to cool fertilizers with a certain temperature and granularity. If used in combination with a dryer, our cooling machine can largely increase cooling speed, reduce labor intensity, and improve finished-product quality. Meanwhile, it can further reduce materials' water content. Additionally, our cooling machines are also applicable for cooling many other powder materials and particles. If you are looking for a rotary drum cooling machine with compact structure, high cooling efficiency, reliable performance and high adaptability, contact with Esong. As a professional cooling machine manufacturer in China, we are confident that we can satisfy your demands.
