Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
The OK Mill was originally designed for cement grinding. In 2017 we released the OK vertical roller mill for raw materials grinding. The OK Mills modular design comes with unique flexibility, showcasing parts commonality, where spare parts can be shared between vertical roller mills
A raw meal ball mill classification circuit was modelled and simulated. 23 capacity increase could be achieved in cement throughput when pre-drying compartment was used in grinding. Static separator operational parameters should be regulated to attain the required cement fineness.

Mar 01, 2018 The temperature of the gas coming into the raw meal department via the hot gas fan depends on the type of raw material being processed. Typically, the hot gas temperature at the inlet to the raw meal department is 180 C for the STD standard type and 260 C for the HS high strength type.The gas flow rate is around 300 kN m 3 h during normal operation.
Re Raw meal to clinker ratio. The true raw meal to clinker factor is given by 1 1 Loss on ignition of kiln feed. It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.

The raw materials are crushed and fed in the correct proportions into a grinding mill, where they are dried and reduced in size to a fine powder. The dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement.

Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material ExtractionQuarry. The raw cement ingredients needed for cement production are limestone calcium, sand and clay silicon, aluminum, iron, shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.
