Cement Production: From Clinker Production to the End Product
Perfectly mixed, accurately fed without pulsation, and precisely weighed
3. Clinker production
Schenck Process’s MULTICOR® K mass-flow feeding system plays the main role in the second cement production stage.
It is used after the raw meal has been burnt in rotary kilns at temperatures of over 1,000 °C to produce clinker. MULTICOR® K has very special qualities for this. Pressure-shock resistant, economical, precise and pulsation-free, it feeds fuels such as pulverised coals or secondary fuels directly into the pneumatic transfer lines to the main burner and calcinatory.
The semi-mobile, compact system feeds secondary fuels such as shredded plastic, sawdust and carpet scraps. MULTICOR® S or MULTISTREAM ® is responsible for feeding the raw meal very precisely into the heat exchanger.
4. Cement production
The clinker is processed into different types of cement. Apart from gypsum and clinker, various additives such as slag sand, trass and fly ash are also ground up with them, depending on the type of cement required.
The MULTIDOS® weighfeeder feeds material into the mill, similar to the earlier feeding into the raw mill. Dusty bulk materials are fed using MULTICOR®, which is also used in the mixing plant.
We recommend our perfectly matched LAS solutions for the loading logistics.
Pneumatic Conveying technology can also be used for the efficient transportation of dusts from ESPs, filters or bag-houses and for the transport of additives into the refining process in a clean, closed pipe system.
