The standard carbon steel or direct-fired rotary dryer collapses under the chemical stresses of industrial salt processing. Chloride pitting corrosion and exhaust flue gas contamination destroy the purity of crystallized minerals. Tongding customized industrial salt rotary drum drying lines are engineered from the ground up to solve these dynamic load and corrosion constraints completely.
1. Complete AISI 304L Anti-Corrosion Defense
Damp salt acts as a harsh electrolyte. To secure a 15+ year operational duty cycle under a 16-hour daily continuous schedule, all interior drum hulls, multi-bending lifting flights, and dust collection components are fabricated from premium non-magnetic 304L stainless steel (wall thickness ≥2.5mm). The contact surfaces undergo intensive 0.4um internal mirror polishing to eliminate material surface tension, preventing wet salt crystals from binding or scaling onto the drum inner shell.
2. 100% Smoke-Free Indirect Heating Technology
Industrial or food-grade salt cannot tolerate sulfur dioxide or unburned soot contamination from burner flames. Our system incorporates a heavy-duty, refractory-lined independent Indirect Hot Air Generator. The fuel oil or gas combusts entirely within an isolated alloy chamber, transferring heat purely to clean ambient air through high-efficiency heat exchanger elements. Only clean, heated air contacts the mineral grid, preserving baseline salt color and chemical purity.

4. Zero-Horizontal-Thrust Mechanical Engineering
Processing 50 tons of salt per hour exerts extreme perpendicular pressure on trunnion wheels. Our patented Zero-Horizontal-Thrust Drive System aligns the central girth gear and driving pinion precisely under the drum's vertical center line (deviation ≤5mm). The lateral dynamic load is completely balanced out, reducing driving motor power consumption by more than 30% while extending the trunnion roller and bearing service life by 2 to 3 times under a continuous operation schedule.
5. Anti-Condensation Pulse Dust Filtration
To completely stop hot salt dust from condensing and blinding baghouse components, Tongding plant utilizes an Offline Pulse Jet Baghouse featuring full rock-wool exterior insulation (50mm rock wool layer protected by 0.5mm color steel armor tiles). Beneath the filter hoppers, a patented centerless stainless-steel screw conveyor sweeps fine dust away without powder bridging or shaft packing failure, maintaining an ideal 99.7% air filtration efficiency.

Sludge dryer
This equipment is specifically designed for materials characterized by high moisture content, high viscosity, and fine particle size. It is widely used across industries such as construction materials, metallurgy, environmental protection, mining, petrochemicals, casting, and chemicals. It complements the triple-pass dryer: while the triple-pass dryer is suited for materials with low moisture and good flowability (such as aggregates), the long-cylinder dryer handles materials with high moisture and viscosity (such as coal slime, lithium slag, gypsum, and bentonite).
Sea Sand Dryer
Materials is sent into stock bin by belt conveyor or bucket elevator, then conveyed from material silo to belt conveyor by disk feeder, belt conveyor carry materials into feed pipe.
Sand Dryer Production Line
Drying: Through disk feeder and wet sand belt conveyor, feed wet sand from moist-material bin to rotary dryer for drying, heated by gas combustion chamber.
Rotary Sand Dryer
Tongding Machinery's three-pass rotary sand dryer is a high-efficiency drying solution specifically engineered for dry mortar production, designed to process wet sand and other granular materials with consistent performance. The triple-cylinder nested structure ensures thermal efficiency >90%, final moisture below 1%, and fuel savings of 15-20% compared with single-drum dryers. Ideal for river sand, silica sand, manufactured sand, and construction aggregates.
