A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular slab. Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead.
Petroleum coke (PC) blend with coal is an attractive feedstock for combustion process. The present work investigates the grinding characteristics of PC blend with coal in a laboratory ball mill to ...

Ball mills are always preferred to be operated at full capacity because the power consumption of this type of mill is very high at lower loads when compared with other types. Ball mills can be designed for a very high capacity like 75 tons per hour output for a specific coal. Vertical spindle mill. There are many different varieties of vertical ...
The ball mill is used for grinding materials such as coal, pigments, and felspar for pottery. Grinding can be carried out either wet or dry but the former is carried at low speeds. The advantages of wet grinding include lower power consumption (20 to 30% less than it dry grinding) increased capacity, reduction in the formation of fines ...

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be % ~ %, while that of raw coal is % ~ %. Therefore, the ball mill should have a drying function besides grinding.

From the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric feeders.

The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by another bucket elevator. The powder separator consists of a centrifugal rotor, 6 cyclones and a selfrecycling pneumatic system. Large size particles return to the mill, and fine powder is collected by cyclones and then

A new realtime 3D dynamic image analysis system was used to measure the particle shapes of different type of coal samples (lignite and hard coals) ground by different mills (ball and gyro mills).
In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.
