Dipping
Tubes
Thimbles help increase the pre-heating efficiency by improving the separation of gas and material. We recommend them for high temperature cyclones where heat exchange is important.
Industry : Cement / Power Stations / Mines
Equipment : Cyclone preheaters / Fluidizing beds / Calciners
Principle :
Rings made of independant sectors and hooked to each other to form a tube of required length
Tech Specs :
* Cast segment tubes
* Large variety of designs and alloys
* Modular system
Key Benefits :
* Easy instalation : light parts, segments without bolts or welding
* Operating reliability : design adapted to application requirements, unhindered expansion thanks to segmentation, reliable hooking of segments
* Optimized lifetime : material adapted to harmful environments and operating temperatures |

Kiln
Nose
-
Ring
Nose-rings are subject to various constraints : high temperature and abrasion, mechanical load, chemical attacks... Reliability is critical since failure results in kiln downtime.
Industry : Cement / Lime
Equipment : Kilns
Principle :
Boxes filled with refractory castable and installed on independant supporting system
Tech Specs :
* Heavy duty design
* Protective boxes replaceable independantly of the supports
Key Benefits :
* Optimized lifetime : material suited for extreme working conditions |

Brick Retaining System
Brick movements affect all kilns. Classical retaining rings are often insufficient to prevent these which means pressure on the nose-ring segments leading to deformation or breakage.
Industry : Cement
Equipment : Kilns
Principle :
Four to six conical rings to stop the brick thrust
Tech Specs :
* Rings made of slanted segments to transfer the brick axial thrust to radial forces
* Light cast parts with honeycomb structure
* System developed together by RHI and Magotteaux
Key Benefits :
* Definite and reliable brick retaining system
* Protection of the kiln discharge |

Satellites
Parts are selected and installed in the cooler according to the specific operating conditions of each kiln in order to optimize the cooling of material.
Industry : Cement / Mining
Equipment : Satellite coolers
Principle :
Specific layout with various types of lifters in order to optimize heat exchange
Tech Specs :
* Large variety of alloys and designs adapted to the position in the tube
* Unique and reliable fastening systems
Key Benefits :
* Optimized cooling efficiency
* Better heat exchange with less clinker dust
* Increased lifetime |

Bar
Grates
Between inlet and outlet, cooler grates are subject to high temperatures, impacts and abrasion. Specific designs have been developed for each particular zone of the various cooler types.
Industry : Cement
Equipment : Grate coolers
Principle :
Pocket grate with efficient selfcooling
Tech Specs :
* Large variety of alloys
* Tangential blowing through slots
* Pockets for clinker retention
Key Benefits :
* Increased lifetime
* Constant open area independant of wear
* Solid and reliable grate for all operating conditions |
