Lime slaker classifier is commonly used equipment in chemical plant for producing milk of lime.

The making of milk of lime is technically called as the Slaking Process. The slaking of lime is basically the hydration reaction of lime (CaO) to Calcium Hydroxide (Ca(OH)2). The hydration of lime is an exothermic reaction and hence generates heat. A rapid hydration would result in excessive heat generation. As hydrated lime is immiscible in water, the milk of lime is usually kept suspended in the slurry by agitation. The particle size of hydrated lime in the slurry is greatly affected by heat generated during the slaking process and the shear force on the particle by agitation. Excessive heat generation and agitation cause decripitation of the slaked lime and result in difficulties in the processes involving slaked lime. Hence, the process conditions involving the production of milk of lime have to be controlled reliably within fairly tight specifications.

Paramount Limited make Lime slaker classifier takes care all the practical requirements of milk of lime plant, i.e, feeding, slaking and classifying processes to produce consistent quality milk of lime. Feed lime (CaO) is fed to the slaking compartment by a variable screw or belt arrangement. The slaker utilises a turbine type agitator. The tank is typically made of cylindrical construction if the capacity involved is large or of square construction for smaller capacities. The solid concentration in the Milk of lime slurry is normally maintained between 10 and 20%.

The slaker is connected to the classifier tank by a liquor and a froth opening. The gritty impurities in commercial lime are separated through an internal raking mechanism ensuring that the milk of lime produced is free from suspended impurities. The accepted milk of lime overflows the classifier compartment and is transferred (usually) by gravity to a storage/ causticizing tank. Grit and unburned cores pass out of the bottom of the classifier up the inclined sloping bottom of the classifier tank by the drag mechanism and discharged over the top of the ramp.

Special features and advantages of “Paramount” make Lime Slaker Classifier:

• Smaller Floor area: A single unit replaces conventional multi-units, occupying smaller floor area, for a given feed rate.
• Reduced Investment: The capital investment is much lesser than that of conventional separate drum slaker and rake slaker classifier units with similar capacity.
• Minimum retention time in the slaker for optimal and economical sizing.
• The slaker tank is closed and provided with suitable vent arrangement. This arrangement provides safe working area as it channels out the hot vapour through the vent pipe as against the regular open top slakers.
• Specially designed baffles are provided to deflect the slurry stream to the classifier bottom and to avoid short circuiting of grits to lime slurry stream to storage/ causticizing tanks.
• Axial flow turbines are equipped with stabilizing fins to minimize shear of lime particles due to vortex and eddies.
• Variable screw feeder help in optimizing the slurry concentration.

Paramount Designs and fabricates baffle type Inline Static Mixer to achieve complete mixing of dosing chemicals with effluent/water.

The Static Mixers are fitted with piping and do not require any additional support structure.

The Static Mixer fabricated by Paramount are designed to have low pressure drop & have no moving parts.

Paramount make Conventional Tank Flocculators use slow speed paddle type mixers mounted on a steel or cement concrete tank to effectively mix flocculant with the effluent.

The flocculator speeds are designed to provide an adequate effect on settling or rising properties of the solids in effluent/ water. The inbuilt behaviour for less efficient settling or rising properties of colloidal solids with the flocculating agents is compensated by providing adequate short circuiting or back mixing in the Flocculation tank. Back mixing is taken care of by providing an adequate residence time in the flocculation tank. The residence times are normally three to five times higher than the pipe flocculators.

Coiled Pipe Flocculator in conjunction with a Tilted plate Flotator is widely used for removal of emulsified oil, suspended solids etc., present in waste water. Alum and polyelectrolyte are added for floc formation.

Unlike conventional tank flocculators, coiled pipe flocculator is of the plug flow reactor type. The required mixing capacity is obtained by energy exchange due to turbulence.

The coiled pipe flocculator is a novel concept, which facilitates accelerated flocculation with flocs having extremely low variation in size distribution, shape and structure. This phenomenon strongly improves settling or rising characteristics, thus having a favorable effect on the subsequent flotation or sedimentation process.

In conventional flocculators, the settling or rising properties are effects of short-circuiting flows and back mixing, three to five times longer residence time is often required. The pipe flocculator circumvents these problems and results in accelerated flocculation with the extremely flocculated particle. The residence time in the pipe flocculator is normally under half a minute. Thus, the strongly improved settling or rising characteristics have a favorable effect on the subsequent flotation or sedimentation process.

The pipe flocculator offers the following advantages.

The above advantages provide a substantial impact on the economics in terms of space, power, and chemical agents.

The effluent flows through the flocculator pipes, where at predetermined points, the coagulant and flocculant can be injected.

The optimum length of each section of pipe flocculator is calculated for every individual application to decide the precise location of injection points for various coagulants and flocculants. The coagulant is injected at the entry section of the pipe flocculator where plug flow condition exists. It is dosed through a mixing flange where total mixing is achieved in less than 0.5 sec, by maintaining a very high turbulence value. The injection of coagulants and flocculants at exactly predetermined points on pipe flocculator provides optimum reaction adjustments and offer gradual built up of flocs along the total length of pipe flocculator.

If pipe flocculators are installed with a flotator, air saturated water (recirculating treated water) from the outlet side of the flotator is mixed at the fag end of the flocculator, the flow receives air-saturated water.

The conglomerates are subsequently separated in the TPF (Tilted Plate Flotator).

Particular care is taken for the design of mixing nozzles for coagulants / flocculants to ensure its complete mixing in the liquid phase.

Clarifiers are extensively used to remove settled solids through the centrally located solids pocket in both primary and secondary treatment.

Primary clarifiers are used in the primary treatment section wherein the removal of suspended solids, heavy metallic sludge as in metal/ mineral benefaction units etc is the primary concern. Secondary clarifiers are installed in bio sludge separation units and are not provided with scum separators.

Paramount Limited makes clarifier mechanism which is suitable for installation either in RCC/ Steel tank. The recommended slope is 1:12 at the bottom of the clarifier tank for efficient removal of sludge. The sludge is scrapped from the bottom of the tank by rotating scrapper arm. Primary clarifiers are inbuilt with floating scum separation box and skimmers. The skimmers gently skim the liquid to surface attached to a rotating skimmer arm.

The following models are available.

A proprietary drive unit comprising of primary internal spur gear connected to the secondary standard worms and worm reduction gear box by means of sprocket and chain arrangement. The standard gearbox is connected directly to the motor mounted on a mild steel fabricated base frame.
