  • pulverizer

    a pulverizer or grinder is a mechanical device for the grinding of many different types of materials. for example, a pulverizer puritch is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants . 1 types of coal pulverizers. 1.1.1 ball and tube mills. 1.1.2 mill construction details. 1.1.3 operation.

  • leadscrew

    a leadscrew or lead screw , also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion.because of the large area of sliding contact between their male and members, screw threads have larger frictional energy losses compared to other linkages.they are not typically used to carry high power, but more for .

  • chuck engineering

    a backplate with threads may screw onto a threaded spindle nose for lathe work or onto an adapter plate with the same nose, to be mounted on the table of milling machines or surface grinding machines. this 'threaded spindle nose' type of mounting was the typical method in the 19th century through 1930s.

  • trommel screen

    a trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. it consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. physical size separation is achieved as the feed material spirals down the .

  • three roll mill

    a three roll mill or triple roll mill is a machine that uses shear force created by three horizontally positioned rolls rotating in opposite directions and different speeds relative to each other, in order to mix, refine, disperse, or homogenize viscous materials fed into it.

  • ball mill

    the ball mill can grind various ores and other materials either wet or dry. there are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

  • mass production

    mass production, also known as flow production or continuous production, is the production of large amounts of standardized products, including and especially on assembly lines.together with job production and batch production, it is one of the three main production methods.. the term mass production was popularized by a 1926 article in the encyclopædia britannica supplement that was written .

  • selective laser sintering

    an sls machine being used at the centro renato archer in brazil.. selective laser sintering sls is an additive manufacturing am technique that uses a laser as the power source to sinter powdered material typically nylon or polyamide , aiming the laser automatically at points in space defined by a 3d model, binding the material together to create a solid structure.

  • cutting mill

    advantages. the cutting mill has many advantages associated with it. it can remove material at a very high speed sometimes without using any coolant. the machine can cut anything from plastic to hard metals. the table of the machine is where most of the movement comes from. a cutting mill can reach an accuracy of a tenth of a thousandth of an inch.

  • stamp mill

    a stamp mill or stamp battery or stamping mill is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. breaking material down is a type of unit operation . a stamp mill consists of a set of heavy steel iron -shod wood in some cases stamps, loosely .

  • trapezoidal thread form

    the original trapezoidal thread form, and still probably the one most commonly encountered worldwide, with a 29 thread angle, is the acme thread form / ˈækmiː / ak-mee . the acme thread was developed in 1894 as a profile well suited to power screws that has various advantages over the square thread, which had been the form of choice .

  • jewel bearing

    a jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole.the hole is typically shaped like a torus and is slightly larger than the shaft diameter. the jewel material is usually synthetic sapphire or ruby .jewel bearings are used in precision instruments where low friction, long life, and dimensional accuracy are important.

  • end mill

    common tool bit types are: square end cutters, ball end cutters, t-slot cutters, and shell mills. square end cutters can mill square slots, pockets, and edges. ball end cutters mill radiused slots or fillets. t-slot cutters mill exactly that: t-shaped slots. shell end cutters are used for large flat surfaces and for angle cuts.

  • drilling

    drilling holes using plastic deformation of the subject under heat and pressure instead of cutting it. reaming reaming is designed to enlarge the size of a hole to leave smooth sides. ;spot facing:this is similar to milling, it is used to provide a flat machine surface on the workpiece in a localized area see also. laser drilling; drilling rig

  • reamer

    a morse taper reamer is used manually to finish morse taper sleeves. these sleeves are a tool used to hold machine cutting tools or holders in the spindles of machines such as a drill or milling machine. the reamer shown is a finishing reamer. a roughing reamer would have serrations along the flutes to break up the thicker chips produced by the .
