Gucheng Huilan Wharf Stone Screen Washing Wastewater Treatment Project (2000 t/h)

— Project Overview —

The 1,800-ton-per-hour fine sand and gravel aggregate project is located at Qingyuan Lan Wharf. The wastewater treatment project for stone washing was contracted by Tuwoda, a subsidiary of Longyue Group. The project recently officially commenced operations, with a current throughput of approximately 1,800 tons per hour, with peak throughput of 2,000-2,200 tons. Water consumption is approximately 200 cubic meters, and the amount of sand produced is small. Each ship takes approximately 2-4 hours to complete. Since startup, approximately 70 tons of sludge has been expelled.

Gucheng Huilan Wharf Stone Washing Screen Wastewater Treatment Project

Project Address: Qingyuan Gucheng Huilan Wharf

Designed Capacity: 1,500-2,000 tons

Application: Washing 1-2 or 1-3 batches

Processing Material: Granite

Workflow:

After the material is unloaded from the truck into the discharge hopper, it is conveyed by a belt conveyor to a VDDH3697 double-deck linear screen for screening and washing. Clean water is pumped from the clean water tank to the screen via a submersible pump. After washing, qualified aggregate above the screen surface is transported to ships via a conveyor belt. The mud, sand, and water mixture at the bottom of the screen flows through a trough to a sand-splitting tank. It is then lifted by a GSB800 sand-splitting machine to a ZZB1835 dewatering screen for dewatering to produce finished sand. The overflow from the sand-splitting tank and the water at the bottom of the dewatering screen flow into a recovery tank, where it is pumped by a slurry pump to a 350-5 cyclone tower for fine sand recovery. The overflow from the cyclone tower is directly deposited in a wastewater tank for sedimentation. Fine sand from the cyclone nozzle at the bottom is piped back to the ZZB1835 dewatering screen for mixing with the finished sand. The supernatant from the wastewater tank is returned to a clear water tank for reuse. The mud at the bottom is pumped by a grouting pump to a chamber filter press for compression. The filtrate is then piped back to the clear water tank for reuse in production.
