Lime wash system


Project description:

Delivery and installation of a complete lime wash preparation system.


Solution/description:

VTS delivered a complete quick lime system, comprising a lime silo for the storage of quick lime with a special discharge system which can fill the batching tanks with lime via two tube screw conveyors. Lime and water are mixed in the two batch tanks and then diluted in a third dilution tank until the required lime wash concentration is achieved.


Performance and production data:
1 lime silo

The hydrated lime silo has a capacity of approx. 70 m3. Below the silo cylinder are the discharge cone and the 3 feet, with an integrated weighing facility for level measurement. The pneumatic air break-up and rapper are integrated in the discharge cone. The rapper supports the air break-up in the lime discharge. The metering unit below is constructed of 2 halves and equipped with 2 drives as well as 2 discharge openings opposite each other. The metering unit can be used to fill 2 quenching tanks at the same time.

Power input: 0,37 kw
Adjustment range of lime metering: 15 to 75 Hz
Lime metering capacity per minute: Approx. 117 dm3
Max. lime metering capacity: Approx. 583 dm3
