The rotary drum dryer belongs to the drying and heat treatment equipment, suitable for drying magnetic, heavy, and floating concentrates of metal and non-metal ores, clay in the cement industry, and coal slurry in the coal mining industry with certain humidity or particle size. It has the advantages of simple structure, convenient operation, and strong adaptability, and is a widely used drying machinery.
Yellow sand, quartz sand, iron filings, iron mud, copper filings, aluminum filings, coal, etc.
Mineral processing, building materials, metallurgy, cement, chemical industry, etc.
Strong adaptability to materials, suitable for energy-saving drying of various powder, granular, strip, and block materials. It can not only quickly remove moisture from materials, but also has simple and reliable equipment operation.
Adopting a new type of multi combination lifting device, it has multiple functions such as guidance, uniform flow, and lifting, which can effectively overcome the "wind tunnel" phenomenon of traditional dryers, allowing materials to fully contact the hot air flow, and the drying heat transfer process is strong and efficient.
The cylinder body is made of steel material, which has high hardness, toughness, and is more wear-resistant; The transmission of large and small gears adopts pin column replaceable gears, with low investment cost. There are multiple lubrication methods for the supporting wheels, effectively extending the service life.
Good sealing performance, complete dust removal device, effectively reducing dust leakage; Reasonable operating parameters, effective utilization of thermal energy, reduction of coal and electricity consumption, and improvement of production capacity.
The cylinder is equipped with lifting plates and guide plates with different angles and spacing, which can ensure that the dried material moves along the spiral direction under the action of gravity, maintaining sufficient residence time and sufficient dispersion inside the cylinder.
Using a self combustion device to generate heat, the wet material is fed into one end of the dryer and undergoes sufficient heat exchange with the hot air flow from the combustion chamber under the flipping of the inclined spiral plate. It then moves to the discharge valve at the other end of the dryer to discharge the finished product, thus completing the drying operation.
