In environmental protection water treatment, power and thermal power, metallurgy, chemical, building materials, and new energy raw material production projects, the dosing of powder chemicals such as lime, activated carbon, calcium hydroxide, and calcium carbonate has always been a difficult point in project operation and maintenance. Manual feeding produces heavy dust and high labor intensity; the chemical mixing concentration is unstable; the material easily arches and cakes during discharge, causing material interruption and dosing fluctuations, which directly affect process treatment results. Ligo Pump's large powder silo preparation and dosing system integrates five functions—powder storage, arch-breaking discharge, metered conveying, solution preparation, and metered dosing—providing stable and reliable fully automated complete equipment for enclosed powder dosing.
Powder materials are conveyed into the powder silo for storage via enclosed conveying equipment. Equipped with air discs, air hammers, and vibrating hoppers as multiple arch-breaking mechanisms, it eliminates powder bridging and caking to ensure stable discharge. The powder is metered by the feeding device and screw conveyor into the preparation tank, where it is thoroughly mixed with process water to form a uniform suspension. The prepared solution is then metered and dosed to the downstream treatment system by conveying metering pumps, with the entire process running in a closed automated loop.

✅ Precise metering, stable solution concentration. Stable feeding and metering control reduce errors from manual intervention, ensuring consistency of chemical mixing concentration and avoiding chemical waste and process fluctuations.
✅ Intelligent PLC fully automatic control. Equipped with a PLC intelligent control system and an HMI interface, it supports remote monitoring, parameter adjustment, and fault alarms from a host computer; automatic/manual dual-mode switching adapts to both batch and continuous dosing conditions.
✅ Multiple arch-breaking for smooth, stable discharge. The three-stage arch-breaking and anti-bridging design of air discs, air hammers, and vibrating hopper solves powder caking and bridging problems, ensuring continuous feeding and stable equipment operation.
✅ Fully enclosed and environmentally friendly, improving the working environment. Enclosed conveying combined with silo-top dust removal effectively suppresses dust dispersion, reduces on-site dust pollution, improves workshop working conditions, and meets environmental control requirements on site.
✅ Continuous dosing with flexible adaptation to operating conditions. Supports both batch and continuous dosing modes with stable, controllable discharge; can be customized according to site conditions, treatment capacity, and space layout, adaptable to various powder materials and diverse process requirements.
✅ Skid-mounted integration for easy on-site installation. The dosing unit is delivered as a complete skid, greatly reducing on-site installation workload, enabling convenient commissioning and shortening project implementation cycles.
Widely used in power and thermal power, new energy raw materials, metallurgy, environmental water treatment, chemical, building materials, and other industries for the storage, dissolution, and metered dosing of powder chemicals such as activated carbon, lime, calcium hydroxide, and calcium carbonate.
