Concretion

A concretion is a hard compact mass of matter formed by the precipitation of mineral cement within the spaces between particles and is found in sedimentary rock or soil Concretions are often ovoid or spherical in shape although irregular shapes also occur The word 'concretion' is derived from the Latin con meaning 'together' and crescere meaning 'to grow'

Milling is the most common form of machining a material removal process which can create a variety of features on a part by cutting away the unwanted material The milling process requires a milling machine workpiece fixture and cutter The workpiece is a piece of pre-shaped material that is secured to the fixture which itself is attached

There are different type of mills Bowl Mill Tube mill Ball and race mills etc are available in India There are pressurised Mill and suction type Mill I will limit my discussion on BHEL make pressurised Mills BHEL supplied other mills also on demand but not on regular basis MILL Purpose of the Mill is defined below :-

The mixed material is milled by a horizontal planetary ball mill for 5 h and the rotation speed of the ball mill is 5 rpm/s The mixed powder containing liquid medium is subjected to ultrasonic dispersion for 2 h and dried at 40 C for 2 h to produce graphene-modified WC-17Co spray powder with a particle size of 35–50 μm

End milling - An end mill makes either peripheral or slot cuts determined by the step-over distance across the workpiece in order to machine a specified feature such as a profile slot pocket or even a complex surface contour The depth of the feature may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes Chamfer milling

Types of Supports for Loads

Roller supports are free to rotate and translate along the surface upon which the roller rests The surface may be horizontal vertical or slopped at any angle Roller supports are commonly located at one end of long bridges in the form of bearing pads This support allows bridge structure to expand and contract with temperature changes and without this expansion the forces

Gold recognizable by its yellowish cast is one of the oldest metals used by humans As far back as the Neolithic period humans have collected gold from stream beds and the actual mining of gold can be traced as far back as 3500 B C when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry religious artifacts and utensils such

To ensure that a steel bridge design can be safely economically and reliably executed (fabricated assembled and erected) designers should be aware of the processes of fabrication and erection the capabilities and limitations of the steelwork contractor and how the design choices affect those processes This article provides guidance on design for construction: it
