They are ideal equipment for corrosion resistance, high temperature, high pressure reaction, pressurized leaching, slurry heating and extraction processes. Horizontal multi-stage continuous reactor is a chemical equipment for intermittent multi-chamber reaction. When the material enters the horizontal multi-stage continuous reactor for chemical reaction processing, the material will enter different reaction chambers in turn for heating and pressurization reaction, vacuum reaction, cooling reaction and other processes, and the stirring requirements of the material when entering different reaction chambers are also different.
