Dongding - Mineral Ore Concentrates Rotary Dryer
Ore concentrates (powder) comes from mineral ore through crushing, grading and other processes. After ore concentrates is separated, the moisture content is very high. In order to facilitate transportation and increase the profit of the ore concentrates, the drying process is needed.
Dongding ore concentrates is mainly consists of feeder, rotary drum dryer, discharging machine, induced draft fan, cyclone dust collector and distribution cabinet, etc. The full drying plant can dry the ore concentrates from the moisture of about 30% to the moisture less than 5%, and final product with the particle size between 5~20mm. The ore concentrates dryer system is not only used for drying materials with high water content and powdery bonded mass, but also can dry the gypsum, kaolin, bentonite, clay, coal slime, etc. This drying system is widely used in building material, chemical, mineral processing, refractory and other industries.
Industrial Rotary Dryer
Dongding - Model DDMG Series - Sludge Rotary Dryer System
Dongding Sludge Rotary Drying System is suitable for drying various kinds of sludge with high viscosity. The sludge with moisture of about 85% can be dehydrated and dried into dry powder with moisture less than 10%. After dried, sludge weight will reduce by approximately 60%; and the volume of sludge will reduce by 4-5 times. Thus, the transportation cost of sludge will reduce significantly. Also, environmental problems associated with sludge will reduce substantially.
