Lime manufacturing and lime slaking process:

• Limestone or calcium carbonate (CaCO3) exists as a natural stone throughout the world. Limestone in its natural form is very slow reacting therefore, it has a limited use
• The most significant use of pulverized limestone is in agriculture in a finely ground and dry form or in flue gas desulphurization in slurry form
• The use of lime in carbonate form is beyond the scope of this paper
• We will concentrate on lime as calcium oxide and calcium hydroxide
• In most pollution control applications lime is used as calcium hydroxide
• To manufacture calcium hydroxide the limestone calcium carbonate must be converted to calcium oxide and the calcium oxide then converted to calcium hydroxide

Screw conveyor technology is the leading conveyor technology for the widest range of material particle, bulk density and flow properties.

Dust-free in operation :The screw conveyor is completely sealed operation air isn't used as a conveying medium, there's no risk of dust contamination or humidity from the atmosphere, In addition, the presence of dust can cause not only airborne contamination of other products, but can also pose a threat to the working environment.

Gentle handling of product :The rotating screw , being centralised within the conveying tube, gently moves the material without degrading it. Its unique action also eliminates the risk of mixed product separation.

Screw conveyor spiral selection :Standard Pitch, Single Flight Conveyor screws with pitch equal to screw diameter are considered standard. They are suitable for a wide range of materials in most conventional applications.

Short Pitch, Single FlightFlight pitch is reduced to 2/3 diameter. Recommended for inclined or vertical applications. Used in screw feeders. Shorter pitch retards flushing of materials which fluidize.

Applications versatility across the widest range of industries.

• Food
• Pharmaceuticals
• Plastics/rubber
• Chemicals
• Cement
• Water treatment
• Minerals/ceramics

Operation : It operates on the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to get the required size reduction. Material fed in the hopper goes down to the processing chamber where it moves to the periphery and passes through the screen radially and tangentially. Finally the processed material gets collected in the container kept below the processing chamber. Output and quality of the final product depends on three main factors :

• Shape of beaters (knife/impact edges)
• Speed
• Screen

Application:

Chemical, Food,  Animal Feed, Pharmaceutical, Fertilizer, Plastic, Pesticide, Solid Epoxy resin,  Cosmetic, Ceramic Powder,  Building Material, Metal, Mining industry,  Metallurgy, Pigment & Dye, Road Painting,  Rare Earth ect

Features:

• Sturdy construction
• Corrosion resistant finish
• Durable

Details :

• Agitated Nutsche filters consist of a cylindrical shell with welded dished end at the top and either a flanged and bolted dished end or a welded dished end / flat welded end at the bottom depending upon process/customer's requirements
• By means of a perforated plate, provided with suitable filter cloth or porous cloth, the vessel is divided into two compartments
• An agitator of unique design is provided inside the vessel
• By manipulating movement in vertical and rotational directions simultaneously, the agitator can perform various activities with the use of push buttons switch/PLC
• The filter is capable of operating under pressure or vacuum or a combination of both
• The filter precludes any possibility of atmospheric pollution from toxic fumes/ obnoxious smell of slurry by working as a completely closed system

ADVANTAGE :

• All operations can be handled by a single unskilled person with little training.
• Proper washing of cake due to re-slurrying resulting in thorough particulate washing. This reduces numbers of washes and volume of wash liquor.
• Reaction filtration, washing and distillation is possible in the same equipment. In some cases, drying operation can also be carried out in the same equipment.
• Heat transfer surface can be provided with the help of a jacket or limpet coils on the vessel walls.
• Indirect heating can be provided on the filter base and agitator.
• Available in special construction for sterile applications with high standard of particulate purity.
