Standard belt widths offered ranging from 400 mm up to 2000 mm as per IS 11592 1983 as well as CEMA standards. However, belts with intermediate widths are also supplied depending upon customer requirements.

Various types of supporting structures are offered starting from a simple stringer with short supports to the more complex conveyor gantries/galleries with walkways on one side/both sides and sheet cladding. All structures are designed for high strength to weight ratio and also for minimum deflection and vibrations.

Standard drive unit and electrical safety switches of superior quality with proven performance provided. Integral hold back in a gearbox and/or brakes is provided in inclined conveyors as applicable.

Auxiliary equipments Standard trippers & shuttle conveyors requires utmost attention as these increase the usefulness of a conveyor system. These are designed and manufactured for discharge or distribution of materials from the belt at one or more points or over length.

Indiana engineers have, over the last three decades, accumulated experience in elevating a variety of bulk solids and in the process solved many complex problems faced by customers. Indiana bucket elevators are made to a standard high quality design based on IS / DIN Standards. Indiana's specialty are Super capacities chain type Bucket elevators for Fertilizer plants that have gained customer delight. Casings are fabricated from steel sheets & liberally stiffened to give added load carrying capacity and true alignment. Buckets are made in various shapes and sizes with edge reinforcements wherever necessary. Chains are normally used for elevators with heavier duties, high capacities and lifts. Belts are recommended for handling free flowing materials as also for corrosive materials while pin and bush type chain is normally used. Link chain & U-bolt combination is provided on heavy-duty elevators depending on the applications.

Following types of elevators are included in Indiana's manufacturing programme to cover most of the applications:

1. Centrifugal discharge belt / chain (Pin and Bush or Link chain) type.
2. Continuous discharge belt / chain (Pin and Bush chain) type.
3. Positive discharge chain type.

Chain conveyors are used to handle granular and medium lumpy materials such as ores, coal, carbide and similar materials. The most common design is that of a Double Strand Link or Pin & Bush type chain with scrapper plates mounted in between. Special purpose chain conveyors are also manufactured to suit individual requirements. Special fabricated / forged chain and attachments are used on bulk flow conveyors (Redler type), while link chain are used on conveyors for coal mines and other applications.

Gravity and Power-driven roller conveyors are manufactured and supplied for industrial use. These are also used in packing plants. The end bearings of rollers depend on the load and duty conditions as well as customer preference include standard ball bearings in machined housing, nylon bushes, non precision (uncaged) ball races, etc. The steel section frames have sufficient strength to ensure that deflection under load does not adversely affect the distribution of the load over the rollers. In power-driven roller conveyors, individual rollers are driven with duplex roller chain and sprockets Powered through geared motor drive unit for conveying. Special ball transfer units or 90 degree bends are offered to make conveying materials in various profiles as required in packing plants.

Indiana's Bin Activator is designed to avoid unscheduled flow interruptions from a silo by breakdown of shear strength thus inducing a smooth flow. The standard range is available from 400 mm dia to 3000 mm diameters in either mild steel or stainless steel construction.

Vibrator motor breaks the vertical bridge of material between the baffle cone and the dish to feed the material into the discharge cone. The vibrations can be increased or decreased to get a controlled rate of discharge.

Indiana Hammer Crusher/mill achieves breakage by precision from swing hammers linked to high-speed rotor that strike the material fed into the crushing chamber. It is used as a primary machine when fitted with heavy duty, double or triple head hammers, and as secondary or tertiary machine with lighter single or double head hammers. Offered in various sizes upto 1200 mm dia x 1400 mm widths.

Indiana Vibrating Screen is designed with a high ratio of capacity to screen area. All the important factors for the design of vibrating screen namely, eccentric throw, speed, inclination, and directions of rotation are considered for achieving the best results. Large roller bearings with dust and watertight seals are used. The screen body is suspended on springs to eliminate vibrations to the supporting structure. Single, double and triple deck versions are available.

Indiana manufactures portable conveyors of belt as well as chain slat type. Portable belt conveyors can be made either with flat idlers or troughing idlers depending upon the load. The conveyor boom is usually fabricated from steel angles/pipes in order to give a light but strong and sturdy structure. Height adjustment facility is provided with manual / electric winch or mechanical/hydraulic pull jack. The complete conveyor structure is mounted on two wheels with a swiveling castor wheel and tow bar arrangement at the back. An inclined portable conveyor, with a near -horizontal profile at the discharge end is commonly used for lorry loading and unloading applications.

Idler frames are one piece fabricated steel construction with inverted angle and end supports with clearances as per IS/Relevant standards. The frame is jig welded for dimensional accuracy and interchangeability. The rigidity and accuracy of the frame ensures correct roller alignment and helps keep the belt properly trained. The inverted base angle gives a self-cleaning design-eliminating roll and belt damage due to material build-up.

Indiana manufactures screw conveyor flights with pipes of various types and sizes as per customers requirements. Standard screw diameters are offered from 100mm up to 1250 mm. Standard flights as per relevant standards - Helical continuous, Ribbon flight, cut and folded flights, and paddle flights are offered.
