Raw material preparation. From the quarry to raw meal feeding
raw material quarrying. Depending on its characteristics, the raw material needed for the cement production process is quarried by blasting, hydraulic excavators or ripping. A wide range of crushing plants – depending on the material’s properties and type of extraction – can be used for breaking the extracted raw material to the size

What raw materials are used for cement production
The main raw materials for the production of Portland cement clinker are calcareous raw materials and clay raw materials. Calcareous raw material. Raw materials containing calcium carbonate as the main component are all calcareous raw materials. It can be divided into natural calcareous raw materials and artificial calcareous raw materials.

How Cement Is Made
The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.

RAW MATERIALS IN CEMENT PRODUCTION
The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. 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

11.6 Portland Cement Manufacturing
The initial production step in portland cement manufacturing is raw materials acquisition. Calcium, the element of highest concentration in portland cement, is obtained from a variety of calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock".

CEMENT RAW MATERIALS
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
