The suspension preheater, installed in the rear of the rotary kiln in a dry process cement production line, can make raw materials suspended in the flue gas and absorb heat from the hot gas. The raw materials will be preheated and decomposed in the preheater before being fed into the kiln for calcination.

This type of raw material pre-heating machine is a new product developed by Haijian introducing and absorbing foreign advanced technology. It is characterized by low heat energy consumption per unit, high output per unit volume, strong adaptability to raw materials, high decomposition rate, block resistance, etc.Preheater
