The de-sanding machine is a mechanical device used to remove debris attached to the debris screen. In reservoirs or waterways with a high amount of sediment, to ensure the safe and normal operation of hydroelectric power stations or pumping stations, it is often necessary to install a de-sanding machine to facilitate cleaning without shutting down the equipment or emptying the reservoir. De-sanding machines come in various types, including obstacle-free, grab, fixed-barrier, scraper, fully automatic, and debris screen models, and are suitable for the inlets and outlets of large and medium-sized structures, making them an ideal, cost-effective choice.
