### Problem

![YanzhouDongtanCoalDustSpillage](https://blog.martin-eng.com/hs-fs/hubfs/YanzhouDongtanCoalDustSpillage.jpg?width=410&height=305&name=YanzhouDongtanCoalDustSpillage.jpg)The Yanzhou Dongtan coal plant in Eastern China had spillage and dust issues at two conveyor transfer points because material was loaded onto the 40-inch (1000 mm) wide belts traveling 500 fpm (2.56 m/s) with little control over impact or [settling](https://foundations.martin-eng.com/learning-center/settling-zones-at-transfer-points). The result was excessive [fugitive dust](https://foundations.martin-eng.com/learning-center/learning-center/displaced-induced-and-generated-air) from belt #111 throughout the facility. Inadequate chute control on belt #185 caused spillage to get caught between the belt and rubber tail pulley, damaging both. Repeated downtime and increased labor costs for these issues seriously impacted plant production.

### Solution

![TransferPointSolutions](https://blog.martin-eng.com/hs-fs/hubfs/TransferPointSolutions.jpg?width=410&height=307&name=TransferPointSolutions.jpg)After an on-site inspection, Martin Service technicians installed [transfer point solutions](https://www.martin-eng.com/content/product_category/469/conveyor-transfer-point-solutions) addressing both conveyors’ unique issues. On #111, a 16.5-foot (5 m) transfer chute distributed material into a 40-foot (12 m) long sealed stilling zone equipped with a full-length Martin® ApronSeal™ Skirting and a series of Martin® Slider Cradles. The 85-foot (26 m) chute on belt #185 required a Martin® Impact Cradle, Martin® ApronSeal Skirting™, and Martin® Slider Cradle support down the entire length. Both chutes featured a Martin® Dust Bag.

### Results

![BeltSupportReducesDust](https://blog.martin-eng.com/hs-fs/hubfs/BeltSupportReducesDust.jpg?width=375&height=279&name=BeltSupportReducesDust.jpg)Since the installation was completed, visible dust within the facility has been drastically reduced. Respirable dust has been measured at less than 3.5 mg/m3, and total dust is down to 10 mg/m3. Operators report that onsite safety and the overall work environment have improved and that the significant drop in equipment failure rates has substantially increased plant productivity.
