Before raw materials being transported to the cement plant, they are crushed into smaller size pieces by the crusher at the quarry. Compared to large pieces, raw materials in smaller pieces are easier to be loaded and transported, and more convenient for subsequent processing. Phase II: Raw Material Proportioning, Blending, and Grinding
Raw sugar reacts with cement and even small amounts seriously affect the setting and hardening performance of cement. As little as 0.001% of sugar, if mixed with cement, renders it worthless. Some cement companies do not allow cement to be carried on vessels which have carried previous sugar cargoes. Temperature:

Only by strictly limiting the content of Fe 2 O 3 in raw materials and fuels can we meet the production requirements of white cement. Therefore, white cement plants often use high-quality limestone as raw materials and mix with silica raw materials such as pyrophyllite, feldspar, silica, kaolinite, and quartz sand to produce white cement.
Checking logistics costs is an ongoing process for the cement companies. Many are trying to reduce the costs by around 5-7 per cent by optimizing the distance of transport. Statistics suggest that ...

What are the raw materials used in the manufacture of portland cement? A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast-furnace slag. A small amount of iron is also needed.
These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: CARBONATE COMPONENT (rich in calx) is contained in the raw mix in a quantity of 76-80%: Limestone. Mohs hardness is 1.8-3.0. The older the geological fraction, the firmer.
