Description
The vertical cyclone preheater system mainly consists of six parts
1, the upper feeding system: mainly includes the upper silo, the feeding pipe, the feeding method and structure can ensure that when feeding to the preheater body to achieve safe sealing, so that the cold air from the outside can not enter the preheater, and the feeding can be achieved with the help of the bar valve continuous or intermittent feeding.
2, preheater body: it is an important part of ensuring that the material is preheated to about 900 degrees Celsius, it is composed of preheating chamber, suspension device and firebrick lining (which does not belong to the equipment design and manufacturing scope) and other parts. Most of the structure of this part is metal components, some materials according to the need to choose heat-resistant steel, heat-resistant steel can work at a high temperature of 1000~1100 degrees Celsius. In addition, the lining structure of refractory brick has novel design and good sealing, which can ensure that the material is evenly preheated in the preheater and reaches the preheating temperature.
3, the push device: mainly includes the push head, frame and connecting rod and other parts, the push head is made of heat-resistant steel casting or welding, can withstand high temperature, with the help of electronic control and hydraulic system, each hydraulic push rod can be realized according to the automatic control program.
4, hydraulic system: mainly including fuel tank, oil pump, motor, solenoid valve, hydraulic tubing, etc., his main role is to control the push device to complete the push action.
5, the lower feeding chamber: mainly includes the chute, the main body of the feeding chamber, the feeding nozzle, etc. Its main function is to import the preheated material into the rotary kiln for calcination.
6, frame: it mainly includes columns, ring beams, etc., the main role is to carry the upper structure of the preheater.
Performance Advantages
- High productivity:Because the cyclone preheater adopts multi-stage circulation suspension preheating mode, the production efficiency is improved.
- Low heat consumption and small footprint:It can make full use of the heat in the kiln, reduce the burning heat consumption of clinker, and reduce the land area of the burning equipment.
- Low investment, high profit: Cyclone preheater due to the reasonable structure, reduce the use of equipment failure, economic and durable, can be said to be less investment and high profit.
- High thermal efficiency: The preheating and partial decomposition of raw material are completed by suspension preheating to shorten the length of rotary kiln, and mix raw material with hot air in kiln to improve heat exchange efficiency.
Working Principle
By using the high temperature airflow accumulated and rolled in the kiln, the multi-stage circulation suspension preheating method is adopted to make the raw material powder and the hot air fully heat exchange, complete the suspension preheating and partial raw material decomposition, and prepare the raw material for calcining in the kiln.

Question&Answer
Q:What is a five-stage cyclone preheater used in cement production?
A:It is a process equipment that allows the material to be suspended for heat exchange and has the function of collecting materials.
Q:What is the separation efficiency of five-stage preheater cyclone?
A:According to the official website of the fire resources network, the TC type five-stage preheater system, the total pressure drop is 4500-5100Pa, the separation efficiency is 92-96%, and the separation efficiency of the top cyclone of the preheater should not be less than 92%.
Separation efficiency: also known as drum efficiency. Refers to the percentage of the total amount of concentrated latex dry glue that flows out of the centrifuge and the total amount of dry glue that enters the centrifuge.
