PREHEATER

Product catalog summary

Process Description
CHAENG manufactures preheaters classified as cement rotary kiln preheaters and lime rotary kiln preheaters. These preheaters, when used with rotary kilns, utilize the waste heat from high-temperature flue gas at the kiln end, promoting energy savings and environmental protection. The vertical kiln preheater's primary function is to transport cement raw material or limestone into the preheater body, preheating it evenly with furnace hot waste gas. Some materials decompose in the preheater before being pushed into the rotary kiln for calcining, which shortens calcining time and enhances the quality of cement and lime products.

Specifications
The preheaters come in various models with different specifications:

YRQ-04: 4 push rods, 4m height, 200 t/d capacity, 10-50 mm feed size
YRQ-06: 6 push rods, 4m height, 300 t/d capacity, 10-50 mm feed size
YRQ-08: 8 push rods, 4.4m height, 400 t/d capacity, 10-50 mm feed size
YRQ-12: 12 push rods, 4.4m height, 600 t/d capacity, 10-50 mm feed size

Features

Operates at high temperatures of 1000 ~ 1100 ℃ for extended periods.
Novel structure design with good sealing ensures even preheating.
Effectively recovers heat from kiln tail emissions, increasing fuel efficiency and aiding dust removal.
Reduces heat dissipation and saves space when used in calcining systems.
Increases capacity by 30% and thermal efficiency by 40%.

Project Stories
The vertical preheater by Great Wall machinery is utilized in a lime production line with a capacity of 400,000 t/a.

Catalog excerpts

Process Description Preheater made by CHAENG is classified as cement rotary kiln preheater and lime rotary kiln preheater. When the vertical preheater is used with the rotary kiln, it can make full use of the waste heat of the hightemperature flue gas at the kiln end, which is energysaving and environmental protection. The main function of vertical kiln preheater is to transport the cement raw material or limestone from the upper into the preheater body, at the same time preheat material evenly with the furnace hot waste gas discharged after calcining. In the preheating process, some materials are decomposed in the preheater, and then are pushed into the rotary kiln for calcining by the hydraulic push rod. This calcination process not only makes the calcining time greatly shortened, but also obtains a high degree of cement and lime products. Specifications Specification
