Rotary Sand Dryer Introduction
Rotary sand dryer, also called sand dryer or sand dryer machine, is developed for drying river sand, silica sand and artificial sand. Suitable for dry-mix mortar, mining and building materials industries.
Tongding rotary sand dryer ensures stable moisture control and continuous high output. Built with wear-resistant liners, the sand dryer machine boasts low energy consumption and easy maintenance. Multiple specifications are optional, and customized designs are available to meet different capacity requirements. It is a reliable drying equipment for global sand processing projects.
Working Principle
The rotary sand dryer is a concurrent-flow drying system composed of a hot-blast stove, belt feeder, rotary drum, belt discharge conveyor, induced draft fan, cyclone dust collector, baghouse dust collector (or wet scrubber), and an operation control system. Its working principle is as follows:
1. In the feed zone, the coal undergoes rapid heat exchange with high-temperature hot air, causing moisture to begin evaporating; the material is then guided by high-angle feed plates into the main processing zone.
2. In the lifting zone, the coal forms a "curtain" of material that makes full contact with the hot air; moisture rapidly evaporates into steam and is extracted by the induced draft fan, thereby drying the coal. In this zone, the coal remains in a loose state, and its moisture content drops to 15% (or lower). After the heat exchange process, the material reaches the target moisture level and is discharged.
3. The discharge zone contains no lifting plates; instead, the material rolls and slides toward the discharge outlet, completing the drying process. The equipment can be customized according to customer requirements.
Outstanding Advantages of Tongding Sand dryer
1.High-efficiency Combined Lifting Blades: Form a uniform material curtain for high heat exchange efficiency, reducing energy consumption by 1/5. Built-in anti-sticking structure allows flexible adjustment of material residence time.
2.Self-aligning Idlers:
Maintain constant line contact between idlers and riding rings, greatly reducing wear and power loss, and ensuring smoother cylinder operation.
3.Zero Axial Thrust Drive:
Optimized idler and gear design eliminates horizontal thrust, lowering drive power by over 30% for stable and reliable operation.
4.Optimal Speed Matching:
Adopts the best rotational speed adapted to material characteristics for more sufficient heat exchange.
5.High-efficiency Dust Collection & Sealing（Weight Air-lock Discharge Hopper）:
Special dust-collecting end cover ensures excellent dust removal effect. Follow-up sealing device is wear-resistant and temperature-resistant, reducing air volume loss.
6.Anti-sticking & Anti-breakage:
Cylinder vibrating device solves wall buildup of high-viscosity materials; intermediate anti-breakage device reduces material breakage rate by over 50%.
7.Integrated Air Classification:
Materials are directly airclassified and conveyed after drying, simplifying the process and improving environmental conditions.
