In this 1,000,000t/y cement grinding plant, clinker and slag are ground separately. PFG120-50 rolling machine and Φ3.2m×13m cement mill are used in clinker ginding. Φ3.2m×13m ginding machine and high-efficiency powder separator are used in slag grinding. This plant features are high quality, high productivity and low consumption.
Besides the fineness of powder clinker and fine slag in the grinding production line, accurate measuring and even mixing also need to be paid much attention to. That's why we choose to use the screw measurer as the measuring device and the air slide as mixing device as well as conveying device.
The cement grinding unit manufactured by our company merges drying, grinding, powder classifying, dust collecting and cement packing into a single. It can not only grind cement clinker but also process cement admixture, such as gypsum, fly ash, furnace slag, coal gangue, etc., realizing a stable, high-quality and automated cement production.
Putting Up A Cement Clinker Grinding Plant. Khansons Group has extended its industrial arena by putting-up a Clinker Grinding Cement Plant located at Rupatoli, Barisal all in a row along with its textile industries. This cement project commenced its initial production at 800 tpd and gradually increased the production to the level of.
conversion to cement clinker. The clinker must be cooled before further processing.
