Lime Hydration Plant 1t/h to 3t/h

For 1t/h to 3t/h small lime hydration plant, the hydration unit can use two stage hydration that consists of two separated lime hydrators stacked one on another, or a single bigger-sized 2 or 3 pass lime hydrator that completes reaction and homogenization in one big chamber. For powder classifying unit, there is lime impact mill+classifier or single-cyclone powder classifier available according to the uses of final product.

Product Description:

Lime Hydrator is the most essential part of a hydrated lime plant(also called lime hydration plant). It is an agitated chamber for quicklime(CaO) and water to fully react at a pricisely controlled ratio to produce dry calcium hydroxide powder(also called hydrated lime). The reaction process is called lime hydration.

For 1 tph to 3 tph small lime hydration plant, the hydration unit can use two stage hydration that consists of two hydrators stacked one on another, or a single bigger-sized 3-pass hydrator that completes reaction and homogenization in one chamber. For powder classifying unit, there is lime impact mill+classifier or single-cyclone powder classifier available according to the uses of final product.

Our lime hydration system is installed with high accuracy weighing feeder and electromagnetic flowmeters to control the lime feeding rate and monitor the waterflow. There are thermocouples installed on the hydrators to monitor the reaction temperature in order to timely adjust lime/water ratio to produced high quality product.

Flowchart of 1-3T/h hydration system as below. If enough floor space is available, crushed lime storage silo, hydrated lime storage silo before powder separator is also recommended, which would give more flexibility to the production process.

Based on the specific lime quality and the required quality of calcium hydroxide, adjustments will need to be made accordingly. Please contact us if you need more details.
