Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.

Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.

Portland cement clinker dust may cause irritation of the respiratory system. When Portland cement clinker accidentally comes into contact with water or when clinker or clinker dust becomes damp, a strong alkaline solution is produced. Due to the high alkalinity, wet Portland cement clinker may provoke skin and eye irritation.

For example, in the plains of eastern Montana, western North Dakota and northeastern Wyoming, traditional sources of aggregate are extremely limited and clinker is often used as a substitute. In fact, clinker makes up more than one-third of the crushed stone produced in Wyoming. The presence of clinker has been noted for some time.

Clinker is the primary material of cement, and it is called as semi-finished product. Clinker is a granulated material made of raw meal powder obtained by grinding limestone and clay together by sintering the raw meal in a rotary furnace at 1400°C-1500°C degrees. Produced clinker's mineralogical structure effects clinker's grinding energy.

Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation.
