Yes. We offer customised solutions, using advanced 2D and 3D design along with simulation software to meet specific project requirements.

Yes. Cosben’s engineering team actively supports consultants and EPCs with technical inputs, drawings and design validation during the proposal and execution stages.

Yes. Cosben equipment is designed to integrate seamlessly with existing powder handling and processing systems. Our solutions can be customised to match current layouts and operational requirements, ensuring smooth installation with minimal modifications or downtime.

Absolutely. Compact designs and customised layouts allow integration into existing plants with space constraints.

We manufacture conveying systems, discharging equipment, dust collection systems, mixing and conditioning equipment, level indicators, vibratory equipment and silo accessories. See the full product range.

Cosben’s screw conveyors typically range from 114 mm to 620 mm in diameter to suit various capacity needs.

Yes. Cosben’s gearboxes and motors are designed to be interchangeable and compatible with most existing screw conveyor setups.

Yes. Cosben’s screw conveyors can be equipped with anti-wear coatings for abrasive applications and are designed with high-performance end and hanger bearings for durability.

We offer tubular screw conveyors that operate efficiently from horizontal up to 45°, as well as specialised vertical screw conveyors for 90° upward transport.

Yes. Cosben’s equipment is designed for continuous industrial duty with appropriate bearing selection, drive sizing and thermal considerations.

Yes. Our designs are adapted using appropriate screw geometry, surface treatments, agitation or conditioning to handle sticky or moisture-sensitive materials.

We use advanced design principles considering material density and moisture. For fine powders, we offer fluidisation solutions or specialised mechanical agitation to ensure consistent flow.

Cosben’s equipment features high-performance seals, including double-lip and labyrinth structures. We also manufacture integrated dust collectors and pressure relief valves to maintain a clean, compliant workspace.

For abrasive applications, we apply anti-wear coatings to screw flights and use high-strength materials for shafts to prevent premature wear and failure.

Yes. Cosben’s systems are designed in line with applicable industrial safety norms, including dust control, pressure relief and mechanical safety requirements.

Yes. Cosben’s dust collection and containment systems are designed to help plants comply with environmental and pollution control regulations.

ATEX-compliant or explosion-protection features can be incorporated based on project requirements and hazard classification.

Yes. We provide on-site erection and commissioning services, along with technical training sessions for OEMs and end users to ensure optimal product performance.

Yes. General Arrangement (GA) drawings and technical details are shared for approval before manufacturing begins.

Yes. Complete O&M manuals are supplied with each system to support installation, operation and maintenance.

We recommend a regular lubrication schedule, typically adding grease every 500 to 1,000 operating hours, depending on the material and environment.

Watch for abnormal noise, excessive vibration or a sudden increase in motor amperage (tripping switches), which often indicates bearing wear or material build-up.

Yes. Cosben’s designs allow for easy adjustment and replacement. For example, stuffing box strips can be replaced by simply loosening the tightening bolts once the conveyor is empty.

Avoid overloading the trough (recommended loading below 45%) and ensure the screw shaft straightness deviation stays within 1/1000.

We offer comprehensive support including erection, commissioning and on-site technical training for your operators to ensure peak performance.

We maintain a robust inventory of critical spares such as hanger bearings, end bearings and gearboxes at Cosben’s factory in Mumbai, India to ensure minimal downtime for clients.

Yes. Cosben’s technical team can assist by phone or email for immediate diagnostics. For complex issues, we can schedule a site visit by Cosben’s engineering experts.

All products are backed by Cosben’s standard manufacturer’s warranty against manufacturing defects, supported by our ISO 9001:2015 quality assurance.

We can supply individual equipment as well as engineered systems as part of turnkey bulk material handling projects, depending on client scope and EPC involvement.

Material properties, required capacity, layout constraints, duty cycle, operating environment and application details help us prepare an accurate technical proposal.

Delivery timelines depend on equipment type, customisation level and order volume. Standard equipment may be delivered faster, while engineered systems follow project schedules.

Yes. You can access and download technical drawings, data sheets and questionnaire forms directly from the Resources section.

Yes. All information shared through the website is handled confidentially and used only for technical and commercial evaluation.

Yes. Initial discussions can be conducted by phone or online meeting to understand requirements efficiently.
