CLINKER GRINDING IN CEMENT PRODUCTION

Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.

Adjuvants for Enhancing Herbicide Performance

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
