Safety Labeling. • Attach labels and safety pre-cautions to serve as a guide to the workers. • Attach directions and labels for emergency exits. • Place the label to where they are easily seen lest they become useless. • All workers should have their own materials according safety operations and others.
The first stage of cement production is the extraction of raw materials from quarries and their transportation to cement plants. The raw materials, namely limestone, clay, laterite, and gypsum are quarried in their respective mining areas and transported to the cement plant through different means depending on the context (e.g. a conveyor …

The production process of cement is not very complex but has many steps to be able to go from raw limestock rocks to a quality cement. The steps are the following [Britannica] : Limestone rocks production in a quarry. Crushing the limestone rocks to get fine grounded limestone. Addition of clay and sands.
Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage. A flow diagram of typical quarrying operations is shown in Figure 1. Figure 1. Process flow diagram for limestone quarrying operations.
This liquid mix does not differ much in process and result from the dry mixture but it does have a positive impact environmentally. This comes in the form of a reduction of carbon footprint. Due to the liquid state, the mixture can be transported from the quarry to the cement manufacturing plant without the use of trucks or fuel powered vehicles.
The nominal capacity or rating of the crusher will be governed by the required raw material throughput and the possible working time of the crushing plant. The quarrying operations, of which the crushing plant usually forms part, are in most cases conducted on a single – shift basis with five or six working days per week.
The purpose of the preparatory processing of the raw materials is to convert theses chemically and mineralogical different materials, usually supplied to the plant in coarse …
These mines are generally located near the cement plant. These materials are then crushed and transported to the cement plant where they are stored, homogenized, blended with corrective materials, and processed further for cement manufacture. Figure 4.1 demonstrates the limestone quarry in Michigan, China, and India.
Figure 1: Simplified process flow of a typical cement manufacturing (Kema, Inc. 2005) Quarrying of limestone and is performed by using explosives and all of the raw materials (limestone, marn, clay…etc) are transported to the plant. These raw materials are crushed, finely ground, and blended to the correct chemical composition.

Manufacturing process flow 1. Quarrying and Crushing The quarry (where the mining activity is performed) is located 0.7 km away from the plant and has the main raw materials such as Limestone and shale that is estimated to last for 100 years, the other raw materials (Iron ore, silica sand, gypsum and Pozzolana (pumice) ) are brought from nearby
In this study, a flue gas emission from a cement manufacturing process is considered for development of CO2 capture plant. The cement industry emits approximately 5% of global man-made CO2 emissions.
Quarrying is used mainly in the production of construction and building materials, such as solid stone or crushed rock for aggregates, or for raw materials for processes such as cement manufacture. As a technique, quarrying is normally only used where raw materials of adequate quality and size cannot be obtained economically by other means.
Cauldon cement plant is located between the villages of Cauldon and Waterhouses in Staffordshire and was the UK's first dry process cement manufacturing plant.
