All Dongding dryers come with a 12-month warranty covering parts and workmanship from the date of commissioning. Lifetime technical support and spare parts supply are provided.
Introduction of 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 35% 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.
Advantages of Ore Concentrates Rotary Dryer
01
Efficient Heat Transfer
Specially designed lifting flights maximize heat transfer between the material and the hot gas stream.
02
High-Temperature Resistance
High-temperature-resistant design allows high-temperature hot air to dry materials quickly.
03
Automated Control
Computer automatic control enables remote operation, with drying temperature and time configured to suit the raw material.
04
Self-Aligning Support
A self-aligning tugboat structure keeps the tug and rolling ring well matched, greatly reducing wear and power consumption; a specially designed block wheel greatly reduces horizontal thrust.
05
Multiple Heat Sources
Coal, biomass pellets, natural gas, diesel, and other heat sources are available.
06
Low Investment & Fast ROI
Low equipment investment and operating cost with quick return on investment.
Working Principle of Ore Concentrates Rotary Dryer
The ore concentrates is fed into the dryer uniformly and continuously through the belt conveyor. The high-temperature hot air generated by the heating source enters the dryer through the connecting pipeline, and contacts with the ore concentrates downstream. The dis-aggregation mechanism, movable grate wing plate, cleaning device and crushing and dispersing device inside the dryer are used for mixing, advancing, and strengthening heat exchange with the ore concentrates, which can dry the wet ore concentrates to the final product with moisture about 5% and particle size of about 5-20mm.
