Manufacturing. Portland cement clinker is made by heating in a cement kiln a mixture of raw materials to a calcining temperature of above 600 °C (1 112 °F) and then a fusion temperature which is about 1 450 °C (2 640 °F) for modern cements to sinter the materials into clinker. The materials in cement clinker are alite belite tri-calcium aluminate and tetra-calcium alumino ferrite.

A typical process of manufacture consists of three stages grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill) heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln grinding the resulting clinker to make cement (see Cement mill). In the second stage the rawmix is fed into the kiln and gradually heated by contact with the hot

Re Low temperature cement grinding. Hi Gio Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength. Raj. Reply
