Cement kiln - Wikipedia
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

Boral Cement | Boral
How is the cement works kiln heated? Boral has only one kiln in operation, located at the Berrima Cement Works in New South Wales. This kiln currently relies upon coal for its heat energy. Between 1929 and 2013, the coal was supplied from a mine at nearby Medway, however the coal is now sourced from the Illawarra region.
Cement - Wikipedia
Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln (referred to as co-processing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications.
Cement Industry - an overview | ScienceDirect Topics
To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifications depending on the end use. The packaged product is then shipped to the consumers.

Manufacture of Portland Cement- Materials and Process
The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks. The kiln is supported on the columns of masonry or concrete and rested on roller bearing in slightly inclined position at the gradient of 1 in 25 to 1 in 30.
cement - Extraction and processing | Britannica
cement - cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
Cement Production - an overview | ScienceDirect Topics
Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes.
