3.Quick Lime Hydrating Machine To Make Ca(OH)2 Feature And Application

Experience says that the rate of temperature growth in the reactionchamber (limehydrating) has a major impact on the finished product characteristics.

As a result, water distribution among the several spray points can be adjusted in function of the characteristics of the quick lime utilized and the resulting temperature profile.

The first stage design has evolved from a slow rotating (12-15 rpm) single shaft equipped with large paddles, to a twin counterrotating shafts arrangement, featuring overlapping short paddles, able to reach a speed up to 50-60 rpm.

A frequency converter allow the adjustment of the rotation speed to match the best operating conditions determined on a case by case basis.

An adjustable weir at the end of the 1st stage permit to regulate the depth of the lime bed in function of the raw material characteristics, so that more agitation and/or more holding time can be provided when necessary.

The 2nd stage is also featuring a twin counter-rotating shafts arrangement, but the rotation speed is slower than in the 1st stage, while the chamber volume is nearly double, as the hydrated lime require a much larger volume.

In this chamber the reaction is normally completed and the paddles design has been studied to improve the turbulence.

The 3rd stage, in the past also called “seasoning chamber” has also evolved thanks to the wider availability of high reactive limes.

It may be equipped with a twin counter-rotating shafts configuration, permitting speeds up to 50 rpm for an optimum product ventilation at the end of the reaction.

In this latter case, paddles are installed with a reduced pitch in order to allow a greater agitation, but still keeping the same product speed throughout the chamber.

 

4.Quick Lime Hydrating Machine To Make Ca(OH)2 Details

The quicklime is stored in the service hopper and is fed to the lime hydrator by means of a volumetric chain conveyor and screw.

Thelime hydrating machine is a three stage machine; the stages contain horizontal rotating shaft with paddles to mix continuously the reacting lime and the water.

Thehydration machine is also provided with wet scrubber or bag filter to dedust the waste gases coming from the process.

We have supposed a standard plant that allows get a final stable product with a guaranteed fineness. This result happens using our proven technology with alime centrifugal separating machine working in closed circuit.

TheCa(OH)2 coming from the lime hydrator is ventilated in the centrifugal separator to control the fineness before storage into the silo. Thelimeseparator reject is sent to a separate silo for second usage. .

The fine Ca(OH)2 is stored in a silo by means of a bucket elevator and a semi-automatic bagging machine is installed under silo for package.
