Mill house is the cane crushing unit which consists of cane carrier, cane cutter having cutting knives, milling tandem, bagasse carrier and conveyor. Cane feeding to the cane carrier is done by unloaders and feeder table. As the cane carrier moves, the cane kicker evens out cane load in the cane carrier and then two sets of cane knives cut the cane into small pieces. This process of cane cutting is called 'cane preparation. These cane pieces then, pass through different mills and the juice is extracted. The mills are driven by D.C.motors. The residue which comes out of the mill after extraction of juice is called bagasse.

The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, shale or clay. These raw materials are won from the quarry either by extraction or through blasting. These naturally occuring minerals are then crushed through a milling process. At this stage, additional minerals are added to ensure the correct chemical composition to make cement is in place. These minerals can be obtained from waste or by-products of other industries, such as paper ash. After milling, the raw meal (as it is known) is transported to the plant where it is stored.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. Large Open Cast mines can cover an area of many square kilometers and use very large pieces of equipment. This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors. In this mining method, explosives are first used in order to break through the surface, or overburden, of the mining area. The overburden is then removed by draglines or by shovel and truck. Once the coal seam is exposed, it is drilled, fractured and thoroughly mined in strips. The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or directly to where it will be used.
Transformer processes can be divided into two types:- ferrous foundries and non-ferrous foundries. Transformer processes involve making the mould and the core, melting and pouring the metal into the mould, and finally removing the mould and core and finishing the product. Although different processes differ in the number of steps required to make the final product. Metal casting process starts with creation of mold. Metal that can be molted will be poured into this mould and cooled. The form of metal being used and shape of final product required would decide the material, which will be used to make the cast. A commonly used molding material is sand. Investment materials, metals, etc. can also be used. .
The building techniques were simple but effective as they reduced the travel time considerably and connected one place to another by land. The Appian Way in Rome still exists although it was constructed 2300 years ago. If Roman roads are considered the beginning of road construction, Telford Pavements are known as the second step of this process, followed by the Macadam Pavements that ultimately lead to the Bitumen Roads. Today, the concrete roads have added another dimension to stability and strength of the roadways.
