Ultrafine Air Classifying Mills are used for size reduction of various products to microfine particle sizes. The system incorporates integral classifier where the fine particles of desired size are segregated and the over size particles back to the grinding chamber and re-grinded until the desired particle size is obtained. Air Classifying Mill is very compact and efficient, having sharp classifier cut points which are instantly adjustable. The system incorporates grinding and classification in one single compact space saving design.  Features : Grinding and Classifying in one machine Cool and smooth grinding Steep particle size distribution Sharp Classifier cut point, instantly adjustable. Easy cleaning and maintenance. Low specific energy requirement Compact space saving design. Principle Of Operation :The material to be ground is conveyed from a hopper by screw feeder or pneumatically fed through Rotary Air Lock Feeder to the grinding chamber of the Air Classifying Mill (ACM). The pins/bars of the rotor break the particles of the material. These particles are entrained by an air stream which enters below the pin rotor and are carried up between the inner wall and the shroud ring with baffles which decrease the air swirl. These particle then enter the classifying section where the fine material is carried out with the air through the classifier rotor to the outlet, the course material is thrown against the shroud rind and carried down to the pin rotor for further reduction. After leaving the micron air mixed with fine particles enter the bag filter where the fine particles are separated and the clean air is discharged to the atmosphere.

Thermosyphon Vessel is used as a storage & unpressurising unit. Used for double mechanical seals in tandem seal arrangement. This is equipped with cooling coil inside the shell to bring down the temperature of buffer fluid coming from seal to Thermosyphon Vessel. 

Fabricated of MS to IS:2062 Grade plate. The arms of the stirrer are welded to the hubs, which are keyed and bolted to the central shaft. The hub is flanged to the central shaft in two halves. The arms are welded with end blades. These blades are specially designed in a way that they turn and move the material longitudinally so that the same particle does not remain in contact with surface for long time and uniform heating is provides to the material inside. 

Spray drying is the transformation of feed from a fluid state into a dried form by spraying the feed into a hot drying medium. The feed is pumped from the product feed tank to the atomizing device, located in the air disperser at the top of the drying chamber. The drying air is drawn from the atmosphere via a filter by a supply fan and is passed through the air heater to the air disperser. The atomized droplets meet the hot air and the evaporation takes place, while cooling of the air happen simultaneously. In Spray Drier, after the spray is dried in the drying chamber, the majority of the dried product falls to the bottom of the chamber and enters to a pneumatic conveying and cooling system.

Spin Flash Dryer is used for effective and efficient method of removal of surface or on bound moisture from a feed product. Spin Flash Dryers are designed for continuous drying of cohesive and non-cohesive pastes, filter cakes and high viscosity liquids. Under the action of hot air and mechanical dispersion, the wet cake appears granular and gets fluidized. Instantaneous exchange of heat and mass takes place. The dried materials are taken in the collector as powder products.

A single mechanical seal consists of two very flat surfaces that are pressed together by a spring and slide against each other. Between these two surfaces is a fluid film generated by the product. This fluid film prevents the mechanical seal from touching the stationary ring. An absence of this fluid film (dry running of the pump) results in frictional heat and ultimate destruction of the mechanical seal.Mechanical seals tend to leak a vapor from the high pressure side to the low pressure side. This fluid lubricates the seal faces and absorbs the heat generated from the associated friction, which crosses the seal faces as a liquid and vaporizes into the atmosphere. So, it's common practice to use a single mechanical seal if the product poses little to no risk to the environment. 

IntroductionRotary vacuum dryers offer clean, simple and effective method of drying wet cake, powder and even slurry. Labor and energy costs are minimal compared to tray dryers and product losses during handling are also negligible. Additionally valuable organic solvents can be conveniently condensed and recovered. Working PrincipleThe drying in a rotary vacuum dryer is a batch operation under vacuum. It is possible to dry heat sensitive materials at well below boiling points of water and solvents. Drying time depends on material being dried, amount of solvent or water to be removed, desired final moisture content, permissible jacket temperature etc. The dryer is available in sizes ranging from 100 liters to 20,000 liters gross volume. The volume of wet material loaded into the dryer is usually restricted to 50% of gross volume. Rotary Vacuum Dryers (RVD) also known as Vanuleuth Dryer, is a cylindrical jacketed vessel with a central agitator having specially designed blades. The blades of this Rotary Vacuum Paddle Dryer (RVPD) are so designed that they sweep the entire internal surface and at the same time turn the material so that all the particles are come in contact with the heated surface. The central agitator shaft is supported on the two end bearings housed in bearing housing in such a way that the alignment remains always intact. This central agitator is driven by means of a Motor & Gear box through the bull Gear. Cooling could also be provided by cold water / brine refrigerant through the jacket. The horizontal shell is jacketed to heat the shell with steam / hot water or any other thermal fluid. Limpet coil is provided instead of jacket if the heating media is fluid. A Dust Catcher consisting of bag filter is provided on the top to prevent the losses of material particles after the drying process. A Condenser of adequate heating surface area is provided wherein the evaporated vapors are condensed and these condensed vapors are then collected in the receiver of suitable capacity, placed beneath the condenser. A Vacuum Pump of adequate capacity is provided & fitted to the receiver of these rotary vacuum dryers to create the vacuum in the dryer shell through the Receiver, Condenser and Dust Catcher.

Rotary Kilns are used to heat solids to the point where a required chemical reaction(s) takes place. The Rotary Kiln is basically a rotating inclined cylinder, solids retention time in the kiln is an important factor and is set by proper selection of diameter, length, speed, slope and the internal design.

Rotary Dryers are used to remove moisture from material using hot gases to heat the feed material and to evaporate the water. Rotary Dryers are suitable for drying wide range of materials continuously because of its ability to process material having considerable variation in size and composition.

Rising film evaporator operate on a "thermo-siphon" principle. Feed enters at the bottom of the heating tube and as it heats, steam begins to form. The ascending force of this steam produces during the boiling causes liquid and vapours to flow upwards in parallel flow. At the same time the production of vapour increases and the product is pressed as thin film on the walls of the tubes and rises upwards. This co-current upward movement against gravity has the beneficial effect creating a high degree of turbulence in the liquid which is advantageous during evaporation of highly viscous products and for the products that have tendency to foul during heating surfaces.These types of evaporators are often used with product recirculation, where some of the formed concentrate is reintroduced back to the feed inlet in order to produce sufficient liquid loading inside the heating tubes. Advantages : Ideal for clear, heat sensitive foaming and corrosive solutions. Continuous, single pass operation with minimized retention time. Single or multiple units with high heat economy. High heat transfer co-efficient. Low power requirement. Simple construction. Low floor space requirement. Applications : Food Herbal extracts Pharmaceuticals Dairy Dyestuff Black liquor in paper amp; pulp. Ammonium Nitrate. Sugar Syrups.
