  • ball mill

    the ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. grinding can be carried out either wet or dry but the former is performed at low speed. blending of explosives is an example of an application for rubber balls.

  • coal preparation plant

    a modern coal breaker in mahanoy city, pennsylvania combines washing, crushing, grading, sorting, stockpiling, and shipping in one facility built into a stockpile of anthracite coal below a mountain top strip mine. a coal preparation plant cpp; also known as a coal handling and preparation plant chpp , coal handling plant, prep plant .

  • coal liquefaction

    coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.this process is often known as 'coal to x', where x can be many different hydrocarbon-based products. however, the most common process chain is 'coal to liquid fuels' ctl .

  • coal breaker

    a coal breaking plant, depicted on a postcard in 1907. a coal breaker is a coal processing plant which breaks coal into various useful sizes. coal breakers also remove impurities from the coal typically slate and deposit them into a culm dump. the coal breaker is a forerunner of the modern coal preparation plant.

  • south african class mg 2-6-6-2

    the crusher was driven by a small steam engine which was mounted behind the hand brake column. the crusher reduced the coal to a suitable size for the stoker. the crushed coal then fell by gravity into a chute which led to a receiving bin, fitted below the back buffer beam of the locomotive. from here it was picked up by a bucket elevator which worked in a large pipe.

  • refined coal

    refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite brown coals and raising their calorific values. coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned.

  • refined coal

    some coal-upgrading processes result in a densified coal product that is considered to be a black coal equivalent product suitable for burning in black coal boilers. victorian brown coal with a characteristic moisture content of 60% by weight is regarded as the 'wettest' brown coal in the world.

  • cornish engine

    a secondhand cornish engine was installed at east london waterworks in 1838, and compared to a watt engine with favourable results, because the price of coal in london was even higher than in cornwall. however, in the main textile manufacturing areas, such as manchester and leeds, the coal price was too low to make replacement economic. only in .

  • crusher

    large pieces of ore are broken once, and then fall to a lower position because they are now smaller where they are broken again. this process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher. a cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks.

  • anderton shearer loader

    the anderton shearer loader is a coal cutting machine which was used in the uk coal industry after 1953. the anderton power loader with its cutting drum up to five feet in diameter was patented in 1953. it was successfully used throughout the british coalfields and by 1966 cut half the coal produced and by 1977 it produced 80% of the coal mined in britain.

  • fossil fuel power station

    a fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.the prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

  • mechanical screening

    mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size. this practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.

  • coal assay

    coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite. each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content in terms of aliphatic or aromatic hydrocarbons and carbon content.

  • south yorkshire coalfield

    the coal found in the south yorkshire coalfield was a bituminous coal that was generally used for the production of coal gas and coke. the coke was then used for iron and steel manufacture. some seams produced coal suitable for raising steam, i.e. it had a low ash and sulphur content. finally other seams produced coal for use.
