This Cyclone Pre-Heater is mainly used for heating and separation between the heat flow of rotary kiln and the material. Through the use of computer numerical simulation of the pre-simulation technique system, gas-solid flow field decomposition to low-cost, short period of time based on specific raw materials, fuel, external environmental characteristics and requirements of the production design the best type of pre-decomposition of the system. Has a superior performance, adaptable, easy to operate, reliable operation, investment savings and so on.
