The Research and Development of Rotary Kiln

Henan Hongxing Mining Machinery Co., Ltd. has long been engaged in the manufacture of mining equipment; recently, we do more research on the functional areas of rotary kiln.
1. Our company takes the lead in the comprehensive and systematic study of domestic industrial hazardous waste; we keep depth understanding and research on the physical and chemical characteristics of typical hazardous waste and the commenced thermogravimetric characteristics.
2. As material feeding rate of low fill rate lime rotary kiln has influences on the average residence time, Hongxing experts introduce the feeding rate to the empirical correlation of average residence time.
3. We adopt innovative reactor model, making gas concentration and reaction rate constant as visits parameters, to reflect the mass transfer process in the rotary kiln; as for the theoretical analysis of mass transfer, we establish the non-active layer, active layer and consolidated model; on this basis, we also introduce the concept of effective coefficient powder into rotary kiln material bed, convert the reaction rate of actual mass transfer process to the product of reaction rate and material bed effective coefficient in the ideal state of the whole material bed being in the largest gas concentration, which transforms the mass problem into the calculation of material bed effective coefficient, simplifying calculation way.
4. Hongxing machines experts discuss the feasibility of pyrolysis evaporation and incineration about hazardous waste in rotary kiln.
5. Our company firstly adopts the method of thermodynamic chemical equilibrium calculations to analyses and forecast typical high calorific value hazardous waste product, providing a theoretical data for material processing in the rotary kiln.
