  Underground mining machinery market : Introduction Expansion of underground mining activities to extend the mine life is driving the market for underground mining equipment. Underground mining is the process of extraction of minerals and ores that are buried deep inside the earth’s crust. Major types of underground mining techniques that are used include hard and soft mining. Excavation of hard minerals such as lead, copper, nickel, iron, gold and silver is carried using the hard underground mining process. However, minerals such as potash, coal, oil shale, and other minerals are extracted with the help of soft underground mining techniques. Various types of mining equipment are available in the market based on the type of mineral that needs to be extracted. Equipment used for underground mining include overhead loaders, draglines, shovels, haul trucks, front end loaders, gathering-arm loaders, and conveyors.

  Continuous Variable Transmission for automotive: Introduction The continuous variable transmission (CVT), also known as step less transmission system, is an automotive transmission. The ratio of the rotational speed of shafts, the input and output shaft of a vehicle fitted with automotive continuous variable transmission can be varied continuously within the given range, providing an infinite number of possible ratios. It provides a smoother driving experience and better fuel economy. A continuous variable transmission continuously transfers power without interruption through a range of speed/torque ratio from engine input to output. This contrasts with manual transmissions that offer a fixed number of gear ratios. The continuous variable transmission is a fast shifting transmission in which the torque converter is utilized for transmitting torque. Different types of CVT are available for various applications such as frictional type, electric type, and hydraulic type. Key Drivers...
