  • High-speed steel - Wikipedia

    High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material.. It is often used in power-saw blades and drill bits.It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness).

  • Pulverizer - Wikipedia

    Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low Speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.

  • Pulverizer - Wikipedia

    A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants
