Tough conditions in building material production. Consequently, components such as the bearings and gears in your rotary kilns, mills, roller presses and crushers are incessantly subject to wear. Selecting the right lubricant is essential. A wrong choice may lead to premature failure of a component and in the worst case production stoppage entailing high maintenance costs and loss of turnover.
High temperatures, continuous operation, loads by the ton and cement dust make for tough operating conditions in cement production. Speciality lubricants made by Klüber Lubrication are used for many machines and systems in this industrial sector.

III. Description of the Cement Manufacturing Process Cement is a finely ground powder which, when mixed with water, forms a hardening paste of calcium silicate hydrates and calcium aluminate hydrates. Cement is used in mortar (to bind together bricks or stones) and concrete (bulk rocklike building material made from cement,
WHAT IS LC3?. LC3 is a new type of cement that is based on a blend of limestone and calcined clay. LC3 can reduce CO2 emissions by up to 30%, is made using limestone and lowgrade clays which are available in abundant quantities, is cost effective and does not require capital intensive modifications to existing cement plants.
roller is about 25 mm to 50 mm above the center roller of the other idlers. As training idlers subject the belt to a wide range of varying forces near the idler itself, it is recommended that belt scales are installed a minimum of 18 meters from a training idler. A conveyor should be selected where material can be diverted out of the
