Coarse Coal Washing Plant is a heavy media system used in washing process of +10 mm -250mm coal. Feeding grain thickness might be changed whenever required, without any performance loss during the wash dimension change, on condition that it is within the mentioned dimension interval. Coarse Coal Washing Plant is produced as semi-mobile especially in low capacities.
The most important solid fuel, coal is not a homogenous substance. The most important ones are boneblack, clay, gypsum, marcasite and pyrite. Therefore, coalfields differ alot in various firms, there is even difference between coal samples from the same coalfields. There is oxygen, hydrogen, azote and sulphure in coal other than carbon. The dispersion percentage of these elements vary in different coal types. Brown coal has a water absorbing characteristics. Hence, it involves more humidity. Humidity absorption skill decreases from brown coal to anthracite. The less the absorption skill is, the more the flotation skill increases. Coal is naturally a floatable substance. Some neutral oils are used in flotation to reduce the flotation time and increase the performance. These are gas oil, creosote and fuel oil. Newly acquired coal usually floats more easily than the coal which was extracted from the mine a couple days earlier and left for spooling. The oxygen of the air gets the coalÆs surface oxidized and reduces its floatability even in normal atmosphere temperature. When the coal is not wished to float, it is oxidized with tassium permanganate. %1 NaOH is required to break the oxide layer. Oxidation occurs more in low quality coal when compared to the high quality one. Floatation skills decrease upon that. Control reactives that suppress the foreign minerals should be used to acquire clean coal concentrations. Sodium carbonate and sodium silicate are used to suppress clay and discharge.

CWP Machinary manufactures crushing, screening and clasification plants in the capacities between 25 Tons/Hour and 350 Tons/Hour by utilizing crushers, bunkers and rubber band conveyors according to the kind of the material to be used. The plant is wholly designed onsite and it is delivered fully operational after the production and onsite installation.
CWP Machinery manufactures spiral conveyors in various diameter, various length, and various types according to the purpose from carbon steel or stainless steel materials. Chain Conveyors It is used for the high capacity transport of the granule materials in narrow space, in short or long distance. It usually operates in the galleries of the underground mining firms. It is durable through its driving gear, pads, and conveyor chutes of high quality steel against corrosion.
Lignite Coal, also known as brown coal, is a low-grade coal with high moisture content. It is primarily used for electricity generation due to its relatively low energy output compared to higher-grade coals, offering an affordable fuel option for power plants and industrial applications.

.Fix carbon 95% Calcined anthracite coal for sale Anthracite Filter Media is thoroughly selected from anthracite which yields the highest percentage of carbon. It is then hydraulically classified to reduce mineral matter and ash to a minimum, and finally screened and washed to ensure suitability for filtration purposes. Anthracite filter coal or Anthrafilt is commonly used as sub-fill and as a component of multi-media filters. Anthracite filter media is a durable media with long life and a wide temperature range. It contains no silica to interfere in the production of ultra pure water. Anthracite promotes higher service flow rates and longer filter runs with less head loss than single media filter beds. Backwash rates are reduced as well. Low uniformity coefficient anthracite filter media extends the life of your filter before the media must be changed out. Higher service flows and longer filter runs than equivalent sand filters. â?¢ Unique density allows Anthracite to be combined with other filtration media in multi-media filters. â?¢ Lower uniformity coefficient has less oversized and undersized particles resulting in a highly uniformed bed. â?¢ Due to its medium density, Anthracite can be used in multi-media bed filters providing a unique pre-filtration layer. Anthracite coal filter media Application Anthracite Filter Media is widely used in the process of water quality treatment before and after the production of chemical, metallurgical, thermoelectric, pharmaceutical, papermaking, printing and dyeing, food and so on.
