The refractory lining of a burning zone in a modern cement kiln uses several refractory types that correspond to the different process conditions or requirements. modern cement kilns extensively use magnesite-spinel refractories as the lining materials in the burning zone areas.
Introduction. cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line.this equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
Nearly all cement plants have received permits from their local regulators to co-process these waste derived materials. the infrastructure built at the cement plants to handle these imports from germany, and the experience of operating the cement kilns with these alternative materials, were accelerating factors in polands recent developments.
The cement kiln refractories e-learning course is intended to fill a gap in the cement industry where no formal training in refractories is generally available. engineers will no longer be obliged to gain their refractories experience on the job, with the inevitable consequence of perpetuating mistakes.
