The top weight on the motor shaft rotates in a plane close to the center of the mass of assembly. Rotation of the top eccentric weights creates vibration on the horizontal plane which causes material to move across the screen cloth to periphery increasing the horizontal throw, causing oversize material to discharge at a faster rate. The bottom eccentric weight rotates below the center of mass creating tilt on the screen giving vibration in verticals and tangential plane. Increasing the verticals component of motion, this promotes turnover of material on the screen surface helping maximum quantity of undersize material to pass through the screen. Rugged springs placed over the circular motor base amplifies the vibration.     Salient Features   Double Decker arrangement can be provided Easy dismantling and cleaning Reputed make vibratory motor

Vee Blender consists of two large diameter pipes cut to 80˚ angle and welded together to form a V shaped body. Inlets are located on top of the body, outlet is at the bottom of V point where there is transition from an elliptical to cylindrical discharge port. In operation, material is loaded to a fill level of 50 to 60% of the blender capacity. The Unit tumbles end over end like the double cone blender, but the mixing action is different because of the body shape. As the body tumbles, the material continuously splits and recombines with the mixing occurring as the material free falls randomly inside the body. Mixing is achieved in 5 to 15 minutes with better homogeneity. The free falling action combined with increased frictional contact between the material and the body’s long straight sides result in slightly less gentle mixing, can create slight shear, producing some particle size reduction through attrition. The blender is suited to most powders and is widely used in the pharmaceutical industries. Provision for pin type intensifier bar is used for breaking soft, friable agglomerates, which are found in raw materials or formed during blending to ensure an intimated blend minor additives are used.

  Description A perfect combination of sifting and milling, the equipment was conceived to prevent handling of powder between separate sifting and milling operations. The separation of coarse and fine product size happens in the sifting chamber. The fine powder falls into the main discharge port, while the coarse particles proceed to the adjacent milling chamber. These particles are further broken into fines, which flows to the mail discharge port, thus attaining the uniform product size. The SS 316 sieves present in the sifting and milling chamber actually determines the final product size. Quite extensively used in applications of continuous batch size. Salient Features Air purging interlocks provided at the shaft entry of the sifting and milling chambers. Pneumatic limit switches provided to ensure proper closing of the lids. Inflatable gaskets provided at the interface of the respective chambers to ensure no leakage of the powder particles into the surroundings. AC frequency drives provided for regulating the sifting and milling speed respectively based upon the validation procedures.

The equipment has a cutting edge technology in high capacity sifting and delumping technology.   The Principle of Operation The indeed falls into the sifting chamber. Centrifugal acceleration ensures a continuous flow of material. Finished products are discharged 360˚ around the screen. Impurities are collected in the screening chamber which can be easily removed. The sifting chamber rotates along with the drive at rpm ensuring discharge up to 2 tons  per hour.   Salient Features It is extremely gentle on product as there is low heat generation during the entire process. Noise level below 95db is easily achieved due to the advance drive systems. Almost the entire product is sieved and in case there are lumps, the baffle breaks the same and it is finally sieved. The equipment is extremely compact in design. Also the equipment is made customizable i.e. 1) The cantilever length of the arm can be increased or decreased. 2) The discharge height of the sieving chamber can be made adjustable. 3) The admit distance between the support legs can be widened or decreased depending upon the vessel into which the discharge takes place.           Back    

  Description It comprises a milling head, Conical Sieve and an impeller. The high speed rotary action of the impeller causes the material to get pushed through the holes of the sieve.

Bin Blender Vertical hydraulic clamping type As regards to its clamping, it happens with the help of three hydraulic cylinders which is a part of the blending arm.  In case of heavy bins, (single column blending) it is ideally used. Mostly for 1500 Ltrs to 3000 Ltrs capacity. The blender bin will have to be kept at the point of clamping. There is no maneuvering of the blender bin into the blending arm in this case. All appropriate safety measures are considered. There is a pressure switch in the circuit such that in case of any hydraulic leakage, the main drive motor stops immediately bringing the machine to a halt

The SAAN granulators are extremely quick and efficient mixers of powder. Dry mixing is the first step of the process. After the products are mixed by means of our unique, bottom drive rotating tool (impeller), a binder is introduced into the product. The binder can be added in dry form or sprayed in as part of a binding solution. Spraying occurs though one or more spray nozzles and is quickly dispersed into the product by mixing action of the main mixing tool (impeller) and the chopper blade. The chopper blade, which is positioned in the highest circumferential area of the product acids in de-lumping. Once all of the solution is in the granulator, the impeller and chopper work together during the wet massing phase to produce dense granules of uniform particle size. The system quickly forms granules that are then easily and automatically discharged from a port in the bowl’s side. The wet granules are generally milled as they come out of the granulator. The granules then need to be dried in SAAN Fluid Bed Dryer machine. Back      

Fluid bed drying is a commonly used process in pharmaceutical industry due to its highly efficient drying of granulated material obtained from wet granulation. The drying is achieved through a combination of moisture diffusion from the solid material to the heated air stream and the removal of that moisture by forced air convection. The product to be dried is transformed into low expanding fluidized bed with the aid of drying air added from below by means of specialized inlet air distributor. In this condition, the particles are isolated from one another and kept in constant motion. The high specific surface of the fluidized product helps great amounts of heat transfer. Inflatable gaskets for product container top, bottom and filter housing sealing. Auto shaking of filter bag at settable intervals. Online sampling of product. Automatically controlled by pass. Integrated cleaning system for WIP & CIP. PLC based control for recipe administration and visualization. Vertical explosion design. Explosion proof and pressure shock proof design.

Description Suitable for clamping drums/ cylindrical containers lifting and tilting it. The clamping arm is flexible therefore drums of different diameters can be matched into the arm. The column can be mounted with the drive on the false ceiling or the drive mounted in the top end of the column (independent of the ceiling support). Hypoxic gear box used for the lifting operation very compact and high operation. The clamping operation can be done manually with a help of a mechanical lead screw and an additional hook to ensure complete positive locking. The lead screw can be motorized to ensure locking in an auto mode to ensure that the drum/container does not get damaged due to excessive pressure goes beyond the required limit of the motor trips.

  The double cone blender consists of two cone shaped sections with 45˚ slope. The cone section is welded at their wide ends to a Centre band. The blender is mounted between two trunnions that permits the unit to tumble end over end. In operation, material is loaded to a fill level of 50 to 60% of the blender’s capacity. The blender tumbles and the material in the vessel spreads out. The transition area at the band between the cones prevents the material from siding along the inner wall and instead causes the material to fold over itself this provides gentle mixing with only very slight shear. The blender is ideal for powders of granules that degrade by attrition. The smooth transition area in the vessel also simplifies cleaning because there are no areas to trap particles and cross-contaminate batches. Contra rotary baffles with mechanicals seals of both ends can be provided for critical mixing applications.

  Description Conical screw mixers (also called Nauta Mixers) make use of a conical chamber with a verticals screw that mixes the powder or substance. Convective mixing effect : The convective mixing effect is created by following 3 factors : Axial mixing by the screw. Radial mixing by shape of the cone. Tangential mixing by the arm.   Applications: Gentle mixing of free flowing and segregative powders, pastes and liquids Addition of liquids of powders by means of spray nozzle or intensifier Intensive dispersion of liquids and solids by means of the intensifier Granulation by moisture addition Heating and cooling Drying by means of heat input in combination with vacuum and possible liquid recovery Chemical reactions De-aeration of paste Coating solids with liquids ( with intensifier)    Benefits :   Gentle blending action is ideal for friable or shear sensitive materials One blender can be used for a wide range of Batch size, ranging from as small as 10% of the rated capacity. Nearly 100% of the blended materials are discharged through the bottom valve after completion of the blend cycle Use nearly 50% less power per unit being blended. Less floor-space and are ideally suited to multistory facilities   Special Applications: The conical mixer can be equipped with a high speed rotor for liquid addition or de-lumping product. Rotating up to 20m/s, this rotor creates vortex effect and injects the liquid through the paddles directly in the product resulting in an excellent dispersion or coating. By spraying the liquid in the mass itself in a vortex, we avoid over-moistening of particles and risk of sticking phenomena on the vessel. This intensifier can replace several lump breakers.

Description One of the perfect example of batch blending where sized granules collected in a container, docked to the blender arm, clamped, lifted from a single end and tumbled for the pre-validated time. The low shear blending action prevents excessive fines or changes to particle shape or size. Fast loading, complete discharge, short cycle time, low powder requirement and minimum maintenance are some of the features. Conta blending improves efficiency compared to conventional blenders because of mixing in the diagonal and eccentric planes. Enormous flexibility – different capacity of bins (for e.g. 200 Ltrs., 400 Ltrs., 600 Ltrs.) can be docked in the single fork of the same conta blender. Also various shapes of bin can be accommodated. (For eg: You could dock an Octagonal / V Shaped Blender body in the same arm of the Conta bin) The arm of the bin blender does not have any nylon rollers or pins. It is a simple sliding system with a wedge arrangement for resting.

Ball Mill is one type of milling machine which is used to mill or grind the materials such as large sized particles either active drug ingredients or excipient and agglomerates. Ball mill consists of horizontal  rotating cylindrical vessel or shell with the length slightly greater than its diameter which is mounted on a metallic frame in such a way that it can be rotated on its longitudinal axis. The axis of the shell or vessel  may be either horizontal or at a small angle to the horizontal.  The cylindrical vessel contains balls that occupy 30-50% of the mill volume. The grinding media is the balls which may be made up of stainless steel. The ball size depends upon the feed and the dia of the mill.
