Innovative development of grate cooler technology

This new cooler combines the best solutions for each of the two fundamental, mutually interacting functions a clinker cooler has to accomplish:

 

• Clinker conveying is based on the "walking floor" principle
• Aeration is controlled by self-regulating valves

 

 

High heat recuperation:

• Decoupling of wear effects from aeration
• Wear – if any – will not influence aeration and heat transfer
• Self-regulating aeration
• Sudden changes within the clinker layer are compensated automatically
• No more fountains – optimum aeration on the whole grate

 

Low wear:

• No more perpendicular pushing surfaces that would be subject to wear
• (Almost) no more relative movement between clinker granules and metal parts
• No cast wear parts

 

Easy maintenance:

• No maintenance during the production year
• No exchange of spare and wear parts for at least two years
• Robust modular system

 

Basic principles for best clinker transportation and specific aeration for maximum heat recovery

• Clinker transportation by walking floor
• walking floor bottom and aeration cassette
• Flow regulators
• Clinker crusher
