Vertical Preheater For Lime Rotary Kiln Capacity: 200-600 T/d Cubic Meter (M3)

We manufacture, export and supply best quality Vertical Preheater For Lime Rotary Kiln in Zhengzhou, Henan, China. Details as given below:-
--------------------
Vertical preheater is one of the main equipments for active limestone production line and cement production line. New energy-saving vertical preheater rotary kiln calcinating process preheats raw material to about 800A C in the preheater by making use of the heat of flue gas in the kiln tail. This system is highly automatized and enables a single point of control, which improves production efficiency, makes the production process more humane and intelligent, and makes the production process more convenient.

Working Principle :
According to the position of vertical preheater in rotary kiln system, and the working principle of rotary kiln, vertical preheater works under negative pressure. Heat transmission mode is thermal convection. The material and air moves in the way of convection. When raw materials are fed into the preheater, effective measures must be taken to seal the inlet in order to prevent cold air entering the preheater under negative pressure. This is to ensure the effective use of heat and preheating effect in the vertical preheater.( Specific schematic diagram is as follows).
