Coal is a kind of carbonized fossil mineral. It is organized by carbon, hydrogen, oxygen, nitrogen and other elements, majority used as fuel by human. At present, the coal has 63 times of explored reserve volume than petroleum. Coal was called the black gold and the food of industry, is the major energy since the 18th century. During the Industrial Revolution, along with the invention and application of steam engine, coal is widely used as industrial fuel and brought unprecedented huge productive forces for the society.

Coal can be classified into 10 classes. Lean coal, coking coal, fat coal, gas coal, weak bond coal, non bond coal, jet coal are generally called soft coal; meager coal is called semi-anthracite coal; coal with volatile component over 40% is called brown coal.

2. Vertical coal mill (HLM Vertical Coal Mill): high capacity, large-scale production, easy maintenance, high automatic level, advanced technology. Disadvantages are high investment cost and large floor space.

Phrase two: drying and grinding 1.Coal material with low moisture will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding. The hot air in the mill will dry the coal. This will reduce drying cost. 2.For high moisture material, a dryer should be applied to dry the coal before grinding.

Phrase four: production collecting Qualified powder will flow with the air and be collected in the dust catcher, then the finished powder will be transported to the product storage bin through discharge port. Lastly, the powder will be loaded by tank car or packed by packing machine.

HC1700 Grinding Mill has open circuit system and explosion-proof device, and has 30%-40% higher capacity than traditional Raymond Mill. The whole system is under full automatic control, the easy operation saves up large operating cost. The high-tech equipment brought us large benefit, we are very satisfied with it.

Coal-Mac operates a surface operation producing approximately 3 MM clean tons annually near Logan, WV. The mine utilizes Komatsu 5500 series excavators and numerous Caterpillar front end loaders to move approximately 40 MM bank cubic yards of overburden per year overlying the Five Block, Stockton, and Coalburg coal horizons.

The complex currently consists of one captive surface mine, a preparation plant and two loadout facilities, which we refer to as Holden 22 and Ragland. The company washes all of the coal transported to the Holden 22 loadout facility at an adjacent 600-ton-per-hour preparation plant. The Holden 22 loadout facility can load a 10,000-ton train in about four hours.

Our ATOX Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleum coke and anthracite down to a fineness below 5% +90 micromillimeters (mm) when coupled with a variable speed mill motor.

As the feed material is added to the mill, the moisture evaporates almost immediately. A continuous gas stream from the nozzle carries the finer particles to the separator, where they will be assessed for the specified fineness. For safety reasons, the coal mill is designed with no external recirculation of materials. Material is prevented from spilling over the edge of the dam ring as both the dam ring height and grinding pressure are adjustable.

The ATOX Coal Mills efficient separator allows material that has reached the required fineness to leave the grinding mill and sends oversized material back for further grinding. The fineness is controlled by adjusting the rotor speed. The high efficiency of the separator is due to the rotor being equipped with an outer ring of louvre plates that are hardfaced for longevity.

The durable grinding mill can handle virtually any type of raw coal and has been designed to grind feed materials with varying moisture levels. The ATOX Coal Mill handles feed materials with less than one percent moisture and up to 25 percent moisture, where abrasiveness and stickiness is not an issue for grinding.

The materials used to produce the ATOX Coal Mills segmented wear surfaces are durable and therefore, last longer. The reversal of liner segment option maximises use of these hard surfaces, making sure every surface is exploited while helping to address uneven wear at the same time.

The separator, with the highest mill capacity, ensures high separation efficiency through having a low bypass to reject. An efficient separator leads to a number of benefits including low specific power consumption for the mill motor, low vibrations, energy savings due to minimal pressure loss, and optimised airflow.

Long-lasting durability is extended to the separator where the inside of the reject cone and outlet top section are faced with Densit. The wear plates for the louvres are also hardfaced to maximise wear life.

The ATOX Coal Mills equipment is located at or above floor level for easy maintenance and cleaning. There are easy-access doors for inspection and maintenance of all of its parts, where roller replacement can occur while still inside the mill. For comprehensive maintenance, the large door is removable for crane access.

Our coal mill offers the flexibility of non-inert and inert operation, depending on the exploding potential of your coal type. The tailored layout considers your coal grinding needs, ensuring simple and optimised operation. For example, the availability of heat sources to dry raw coal helps determine the final layout.

Liner segments can be reversed so that the wear, which normally occurs on the outer edge, can be spread evenly, making use of the entire segment surface. The coal mills liner segments can also be repeatedly hardfaced for maximal longevity.

The heated rotary feed sluice ensures uniform flow of feed into the ATOX Coal Mill for optimum mill operation including minimising power consumption. It is the right solution for a sticky feed material as hot gas from the mill inlet is guided through the rotor, preventing the sticky
