Roller mills - Import export

Wear is a damage consisting in gradual removal or deformation of material on solid surfaces, caused by mechanical (e.g. erosion) or chemical (e.g. corrosion) influences. In machine elements, wear may give rise to material failure or loss of functionality. For the application in question, our client has to measure wear on the surface of rollers in cement mills. Up from a certain depth, reactions are required, generated by a warning system to be developed In this project, we used several robust QuellTech Q6 scanners to cover fully the roller width. Due to the high rotational speed of the rollers, we preferred our fastest scanners for this application. We furthermore developed a software solution and implemented a warning system, based on the critical depth of the wears on the surface. By means of this system, the customer can determine the correct time for exchange of the rollers.

Maintenance free, dry, dust deflecting High temperature resistant Wear protection for metal running faces and rails with minimized friction loss and impressive increased life time of application Highly efficient, reduction of noise and environmental impact Main application Cranes Conveyor systems Guiding rollers Pressure rollers at rotary kilns Dryers Mills Rope drives Chain drives Locomotive wheels Carousel shelf systems

require high precision, large rated moving load, and high maximum rotation speed. By adopting the new technology of material processing, KFB has successfully manufactured bearings of long service life that are highly fatigue resistant and impact resistant. The types of bearings made by KFB for the metallurgical roller mills are: split bearings; unit rollers; support roller bearings; single row, double row, three row, four row cylindrical roller bearings, fully-loaded cylindrical roller bearings, spherical roller bearings. The use of split bearings appreciably facilitates assembly and repair operations compared to the use of nonsplit (conventional) bearings. It does away with the need for the disassembly and subsequent reassembly of intermediate parts and mechanisms, which is required when replacing conventional bearings. It also reduces costs and production losses. If provided with efficient cooling, reliable lubrication and proper sealing, split-bearing components can be used...
