- Steel infra Designs, Manufacture and Supplies various Flat and Troughed Belt Conveyors for handling of Bulk Material like Coal, Cement, Iron Ore, Clinker, Lime Powder, Fertilizers etc. We have the experience and expertise to provide “Concept to Customer” solutions in Belt Conveying for various industries and applications. From very short and steep to long conveying, our conveyors can be designed to handle different terrains and tough operating conditions. We have supplied upto 4000mm wide belt conveyors and have in house design capability for conveying capacity of 10000 TPH.
- Our 175 point Conveyor Design Check, ensures that the smallest aspect of conveying is factored in to ensure you have a trouble free performance and life for the conveyor.
- The fact that we manufacture the Conveyor Components like Idlers and Pulleys also in house, ensures that the quality standards are consistent and you have a reliable partner for genuine spares and replacements in future.
- Our screw conveyors are designed to ensure a sturdy pipe design, minimum run out, minimum coefficient of friction, ease of maintenance and reduced power loss. The special sealing system prevents dust entry and trouble free operation. The screw flights are machine formed and are available in various configurations and thickness. The screw flights are hard faced with special electrodes to prolong its life.
- We can provide screw conveyors for highly temperature applications of even 1000 deg and handle all types of harsh materials also.
- The Ramsal Drum Motor requires minimal space on the conveyor frame and completely eliminates the need for external motor, gearbox, chain, sprockets, chain guard or pillow block bearings. By housing all vital components internally, the Ramsal Drum Motor reduces operating & maintenance costs and improves safety conditions. Unique features of Ramsal Drum Motor
- Highly reliable: As a result of the good design, high quality materials and efficient production, Ramsal Drum Motor is totally reliable. The Ramsal Drum Motor is manufactured under stringent quality norms and supervision. Our State of the art machining centers and CNC equipment ensures consistent high quality and efficient production of materials, which guarantees prompt delivery and trouble free operation. .
- High efficiency: The Ramsal Drum Motor design is 30% to 40% more efficient than conventional multi component systems because all the motor's horsepower drives the conveyor. As a result, the drum motor has unusually high torque and power capabilities. The cooling properties of the oil bath enhance torque capabilities by allowing 35% to 40% more motor-heat dissipation than air-cooled designs.
- A totally sealed drive:All components of the Ramsal Drum Motor are housed internally and isolated from the outside environment, enabling operation under any conditions
- Quick and easy installation: The Ramsal Drum Motor design simplifies installation and replacement because all movable parts are housed within the drum shell. No angular mounting restrictions
- Virtually no maintenance: An entire drive system, built inside a conveyor pulley, eliminates the need for high-maintenance components such as motors, gear reducers, chains, sprockets, pulleys and V-belts. The only maintenance required for the drum motor is an oil change every 5000 hours of operation
- Saving in power consumption: Ramsal Drum Motor run at 96% mechanical efficiency, saving up to 30% on power consumption when compared to external drives.
- Clean and safe work environment: Ramsal Drum Motor offers a cleaner system because all drive components and lubricants are sealed inside the drum motor shell. The Ramsal Drum Motor can be hosed down during clean-up, creating a safer environment for workers who would otherwise work around drive chains and guards used in conventional systems. Low noise
- Strong and robust construction
- Water and dust proof for life
- Ramsal Drum Motor Specifications
- Also Available with
- Non standard / extra long
- Flat faced / knurled finish
- Special speed and Horse power
- 'V' grooves for 'A', 'B', 'C' sections of 'V' guided belts

- Idlers are the heart of a conveyor, since reliability and longer life can reduce down time for the conveyors, effect reduction in power consumption and increase belt life. Steel infra idlers operate with very low coefficient of friction and are designed for reliable and guaranteed performance of upto 60,000 hours.
- Troughing / Flat Carrying Idlers
- Troughing / Flat Impact Idlers
- Self Aligning Carrying/Return Idlers
- Flat / V Roll Return Idlers
- Self Cleaning Return Idlers
- Transition Idlers
- Garland Idlers
- Salient features of Steel infra Rollers
- Rollers are manufactured from ERW pipes as per IS: 9295which are specially made for Idlers application. These pipes are specially made with tight tolerances related to straightness and ovality.
- Pipes are bored at both ends simultaneously using a special purpose Double Headed Boring machine. This will maintain concentricity of shaft at both ends of idlers and will limit the run out of the idlers.
- The bearing housings are manufactured from Extra Deep Drawn CRCA sheets.
- The Bearing seating, flange diameter and back facing of the bearing housing are machined in a single setting on a Special Purpose Machine to ensure absolute concentricity.
- Bearing Housings are welded to the pipe at both ends simultaneously by CO2 welding.
- Roller shafts are made of bright bar.
- We use only genuine bearings from SKF/FAG and they are sourced directly from the manufacturer.
- Vertical labyrinth type sealing system is provided for the bearings. The sealing system consists of Double Labyrinth Seal, made of CRCA sheet. Glass beaded Nylon seal is provided at back of the bearing to avoid grease entering in side the pipe. A neoprene rubber seal is provided on top of the outer labyrinth seal to prevent any water and dust from entering inside the idler.
- After the idlers are assembled each idler is continuously rotated for a minimum period of 15 minutes for both freeing of the idler as well as testing for any heating of the bearing.
- As per the Quality Assurance Plan, idlers are tested for Water and Dust Penetration in specially built Jigs.
- The rolling resistance of Steel infra idlers is as low as 0.01 as against allowable value of 0.02 and design value of 0.03 for standard rollwers.
- At Steel infra, all pulleys are custom designed to suit customer's specifications and precession engineered for perfect performance. Steel infra pulleys are suitable for continuous operation and designed as per relevant IS and other international standards.
- Salient features of Steel infra Pulleys are
- Pulley shafts are made of C45 steel and ultrasonically tested.
- All Pulleys will be stress relieved before machining.
- Out of roundness of shaft is limited to 0.2mm.
- Out of roundness of shell maintained to +/1.5mm and face run out is limited to 1.5mm.
- All pulleys are statically balanced.
- Pulleys provided with minimum 8mm thick fillet weld joint.
- The lagging sheets are of natural rubber and are hot vulcanized to the shell.
- Steel infra manufactures various Single/Double Roll crushers for different applications and material like Coal/ Stones etc. With capacity of up to 100TPH our crushers are ideally suited for the construction industry and other related applications
- Steel infra has a range of single/double/triple deck vibrating screens for a maximum capacity of 300TPH.
- The distinguishing features of Steel infra Vibrating Screens are
- High screening efficiency in the rage of 90-95%
