Cement kiln Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium silicatesOver a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plantThe Cement Industry is moving in a constant area of tension between optimum quality, lower costs and shorter timetomarket Whether you are a plant operator, system integrator or plant and machine constructor: the solution to this problem is Totally Integrated Automation Advantages for plant operation): Automation solutions for the Cement Industry

The cement kiln Understanding Cement

The original rotary cement kilns were called 'wet process' kilns In their basic form they were relatively simple compared with modern developments The raw meal was supplied at ambient temperature in the form of a slurry A wet process kiln may be up to 200m long and 6m in diameter It has to be long because a lot of water has to be evaporatedDefects in concrete can often be related to the lack of durability of the concrete, resulting from the composition of the concrete, poor placement practices, poor Quality Control or the aggressive environment in which it is placed Cracking, Spalling, Scaling, Honeycombing, Settlement, Alkali Aggregate Reactions, Piping, Loss of binding pasteDefects in Concrete | Problems and Defects in Hard Concrete
