Lime Dosing System
The lime dosing system utilizes storage silos for sealed storage and continuous feeding of lime powder, providing the downstream lime slurry preparation units and chemical dosing systems a stable powder supply. This water treatment chemical feed system reduces the need for frequent manual loading. Level monitoring, de-bridging, and conveying devices support storage, discharge, and transfer of the lime powder. Typical water treatment applications include municipal water softening, pH/alkalinity adjustment, as well as textile and dyeing wastewater neutralization.
The lime storage and feeding system consists of a silo body, top dust collector, level gauge, de-bridging device, conical discharge outlet, and screw conveyor. Lime powder enters the silo from the top, and the dust-laden air produced during filling passes through the dust collector. The level gauge monitors the stock, and the de-bridging device loosens the powder when it bridges. Lime powder then leaves through the bottom outlet and is conveyed by the screw conveyor to the downstream dissolving or lime slurry preparation unit.

- Sealed silo structure that reduces moisture absorption by the lime powder and prevents dust leakage
- De-bridging device that lowers the risk of bridging and material blockage
- High and low level monitoring for refill prompts and low-stock alarms
- Screw conveyor for continuous or metered feeding based on system requirements
- Integrated operation with downstream dissolving, preparation, and dosing systems for automatic feeding
