At present HANDA own the technical consultants such as Mr Wentao Zhao ( Senior Engineer for Pyro equipment), Mr Frank Peng ( CILS ), Ms Alice Wang ( professor for machine design ), etc. They are founder of HANDA or the shareholders and partner. For more than decades of years, HANDA get the constant innovation and development under their support. For example, Mr Wentao Zhao reserched and developed Multi-layer scales seal for rotary kiln and rotary dryer, which solves the problem of the disadvantage of no resistant of high temprature, leakage of wind and dust of the present totary kiln scale. It enhance more than 2 times of the rotary kiln seal. Ms Alice Wang improve rotary kiln firing schedule under the labrotary data, adopting kiln tail and head seal, perfect preheater and cooler selection, all of which makes the rotary kiln system in high efficiency and energy saving up to 30%.
