the ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. these mills
ball tube mill the ball tube mill is a cylindrical low-speed grinding mill. It consists of a steel barrel, lined with cast abrasion-resistant liners and partially filled with hardened steel balls. coal and pre-heated primary air enter one or both ends of the mill from a crusherdryer or feeder. As the mill rotates, the balls cascade and
ball mill is mainly used for grinding in mining cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect.it follows more crushing and less grinding principle to save energy. the feed size to ball mill shall be smaller than the output size can be adjusted by revising steel balls ratio.
tdgd steam tube rotary dryer is a kind of indirect heating large scale drying equipment. As one of rotary dryer, it is equipped with steam heating tube inner the rotary drum. heating tubes will run through the whole dryer and are sets in one to four rounds in concentric circle form. heat needed for drying wet materials is provided by heating tubes.
steam tube dryer is an indirect heat dryer using steam tubes disposed inside the rotating shell as the heat source. steam is introduced into a header through a rotary joint and then distributed into the tubes. the header is also provided with condensate ejection pipes which discharge condensate as quickly as formed.

dryer coal flows more readily and causes less feeder hopper bridging and plugging problems. coal feeders provide coal to the coal pulverizers where the coal is pulverized and dried. dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness.
steam tube dryer is of a high coefficient energy transmission plant. the drying is done indirectly by the steam via heat transmission tubes, which enables large volume, continuous drying. steam tube dryer is an indirect heating chamber that contains numerous heat transfer tubes.
for nearly 100 yearsever since pulverized coal combustion was adapted for power generationge has been a leader in coal mill technology for the power industry. that leadership continues today with the worlds largest fleet of installed power milling equipment.
