We offer high quality of Screw Conveyor Screw conveyor is use to convey materials from One point to another horizontally and can do so without any dusting and spillage at very reasonable power expense. This equipment can also be used for inclined conveying for which capacity duration to be considered while sizing. This will depend on inclination sought and material characteristics.  This Screw Conveyor is available with options 'U' and 'Circular' trough. AVAILABLE IN TYPES     * RIBBON TYPE SCREW CONVEYOR * PEDDLE TYPE SCREW CONVEYOR * TWIN SCREW TYPE SCREW CONVEYOR * RIGHT AND LEFT SCREW TYPE SCREW CONVEYORS

We offer wide variety of Rotary Airlock Valve. Rotary Airlock Valve (RAV) is the equipment which is fitted below the Bag Filter, Cyclone, Multicyclone etc.  The main function of the RAV is to lock the air and discharge the dust / powder.  In the Bag Filter system there is negative pressure in the Bag Filter.  So at the powder discharge point if there is any air leakage the powder will not fall down.  So to restrict the leakage we provide the Rotary Airlock Valve.  RAV consists of a stator & rotor.  The radial & axial clearance is between 0.1 to 0.3 mm.  The rotor has vanes (6 or 8) welded on the shaft.  The rotor is mounted on the bearings at both the ends of the stator.  A Geared Motor is provided to rotate the rotor.  Since the clearance between rotor & stator is so low.  Because of this air leak is very minimum and it delivers only powder. AVAILABLE IN TYPES     ·          DROP THROUGH ROTARY AIRLOCK ·          SIDE ENTRY ROTARY AIRLOCK ·          BLOW THROUGH ROTARY AIRLOCK

We offer wide quality of Roller ConveyorAvail from us a wide range of Roller Conveyor that caters to the requirements of beverage, engineering and other allied industries.  Manufactured using premium quality mild steel that is sourced from reliable vendors of the market, we ensure that the end product is defect free.  High in performance, these Conveyors are useful to convey various components such as crates, boxes and others from one place to another. Roller Conveyors are small metal tubes placed adjacent to each other and usually rotated by a mechanism beneath, enabling merchandise materials and pallets to be moved from one location to another.  Roller Conveyors can be set up to transport items around curves and up & down gentle vertical slopes. These Roller Conveyors are available with options gravity and motorized.    

Dust Collector system consists of a blower, dust filter, a filter-cleaning system and a dust receptacle or dust removal system. It is distinguished from air cleaners which use disposable filters to remove dust. The dust-laden air enters the Bag Filter. The dust powder separates inside the bag air filter chamber. The air is uniformly distributed avoiding channeling while the powder is separated. Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium. The dust is accumulated on filter elements while the air passes through the filter bags from outside to inside. The accumulated powder is dislodged from the bags by reverse pulse jet air intermittently. The dislodged powder falls on bottom cone and is discharged through powder discharge valves. The dust free air is sucked by induced draft fan and is exhausted to atmosphere.

we offer wide range of multi- cyclone separators when volume of air flow is large, single cyclone tends to become inefficient.  therefore it is recommended to use multiple numbers of cyclones thus called multi cyclone.  it has a common body container wherein numbers of small cyclones are included, each handling small volumes, thus offering better efficiency.  thus, number of cyclones operating together offer far better performance for larger volume than single one.  of course dimensions are favorable too and so the cost.

We have high quality of Flap Valve. Double Flap Valve allows material to flow, while preventing the back flow of air or gas that is critical in many conveying systems. These devices are commonly used wherever dry solids need to be moved between areas of differing air pressure, including ash handling. Typical Double Flap Valve equipment applications include drop-out box hoppers, Dust Collectors, Bag Houses, Precipitators and screw conveyors. Double Flap Valves can handle material like Fly Ash, Sawdust, Lime, Cement, Clinker, Sinter and sand. Other types of material can be collected as long as they are granular, not sticky and flow freely by gravity. This Flap Valve can be motorized, pneumatic & gravity operated.

We offer wide range of Double Cone Valve.  Operations similar to that of Double Flap Valve except special features like 100 % sealing at high temperature & pressure. Usually used in high temperature sinter handling.  These cone valves are available with options motorized and pneumatic operated.  Our clients can avail from us a wide range of Double Cone Valve, which is suitable for air lock applications. These Valves are similar to the Rotary Airlock Valve, widely used in Pneumatic Conveying Systems and Dust Control Equipment. Also, these find application as volumetric feed-controls to maintain an even flow of material through processing systems.  The operations of Double Cone Valve are very much similar to that of a Double Flap Valve.

Diverters employ an axially mounted plate to control the flow of materials.  Flow may be diverted to one of two tubes, which intersect at a fixed angle.  These diverters are available with options motorized and pneumatic operated.

We offer wide range of Cyclone Separators This is a device to separate solids (in powder or granular form) from air/gases. When the material is moving as in pneumatic conveying, the solids are separated. In this device, air is made to flow at cyclonic speed and made to rotate in a cylindrical vessel of suitable design. When the solid material attains high speed, it picks up centrifugal force and choose to hold tightly  to outer surface while air retains high speed it gets due to its velocity factor. Suddenly in the center, air outlet is provided for air to go out while due to centrifugal force the solid material is not able to change direction but goes downwards and gets separated.  This device is capable of offering separation efficiency up to 90 %, of course depending upon design, material, bulk density etc. There is one collecting hopper where material gets collected. Smaller the diameter better is the efficiency.

Chain Conveyor is used in horizontal bulk material conveying for abrasive and hot material which cannot be handled by Belt Conveyors.
