The Vulcanizer is responsible for the inspection, repair, splicing, and maintenance of conveyor belts, rubber linings, and related rubber components across the cement plant.
This role ensures minimal downtime of conveyor systems - which are critical to the continuous flow of raw materials, clinker, and finished cement - through skilled rubber work, hot and cold vulcanization techniques, and proactive belt management.
The Vulcanizer works in close coordination with the Maintenance and Operations teams to support plant reliability and production targets.
Responsibilities
Perform hot and cold vulcanization of conveyor belt joints, splices, and damaged sections to manufacturer specifications and plant standards.
Execute belt splicing (mechanical and vulcanized) to restore belt integrity and ensure tension-bearing capacity.
Repair cuts, gouges, delamination, edge damage, and cover wear on conveyor belts to extend service life.
Apply rubber lining to chutes, hoppers, and wear plates using appropriate bonding techniques to reduce material wear and noise.
Replace conveyor belt sections as required during planned maintenance and emergency breakdowns.
Conduct routine visual and physical inspections of all conveyor belts in the plant, identifying wear patterns, splice conditions, and cover damage.
Maintain belt inspection records and report findings to the Maintenance Supervisor, recommending corrective or preventive actions.
Monitor belt tracking, tension, and alignment, coordinating with mechanical technicians on adjustments as required.
Assess rubber linings on chutes, hoppers, cyclones, and transfer points, recommending relining schedules to prevent structural damage.
Participate actively in planned preventive maintenance (PPM) programmes for all conveyor systems and rubber-lined equipment.
Prepare work areas for vulcanization — cleaning belt surfaces, cutting to correct profiles, and applying vulcanizing agents — in accordance with method statements.
Ensure correct curing temperatures, times, and pressures during hot vulcanization using vulcanizing presses.
Maintain accurate maintenance records, including belt identification numbers, splice locations, repair history, and rubber consumption.
Comply with all plant safety requirements, Lock-Out / Tag-Out (LOTO) procedures, and permit-to-work systems before commencing belt work.
Ensure safe handling and storage of vulcanizing chemicals, adhesives, and solvents in accordance with MSDS / SDS guidelines.
Use correct PPE — heat-resistant gloves, safety goggles, respiratory protection, and safety footwear — for all vulcanizing activities
Report all near-misses, unsafe conditions, and incidents promptly through the plant safety reporting system.
Participate in safety briefings, toolbox talks, and emergency response drills
Maintain an adequate inventory of vulcanizing materials — rubber compounds, bonding agents, belt fabric, and repair kits.
Ensure vulcanizing presses, cutting tools, and grinders are maintained, calibrated, and stored correctly.
Minimize rubber waste and optimize material usage to support cost-efficient maintenance.
Requirements
Education:
OND / Trade Test Certificate or equivalent in Mechanical Engineering or related discipline.
Experience:
4-5 years of post-qualification experience as a Vulcanizer in heavy industry — cement, mining, quarrying, or bulk materials handling preferred.
Demonstrated hands-on experience with hot and cold vulcanization presses and splicing of fabric-ply and steel-cord conveyor belts.
Required Skills:
Thorough knowledge of hot and cold vulcanization techniques, including correct application of heat, pressure, and curing agents.
Understanding of conveyor belt construction - fabric plies, steel cord, rubber covers - and how each affects repair methodology.
Knowledge of belt splicing methods: step splice, finger splice, and mechanical fasteners, and when each is appropriate.
Familiarity with rubber lining materials, bonding agents, and their application to industrial equipment surfaces.
Awareness of conveyor system components (idlers, pulleys, scrapers, chutes) and how they interact with belt condition.
Knowledge of chemical safety (MSDS / SDS) for vulcanizing agents, solvents, and adhesives.
Understanding of plant safety requirements, LOTO procedures, and permit-to-work systems.
Experience with rubber lining of chutes, hoppers, and wear-critical surfaces in an industrial plant environment.
Experience working within a formal permit-to-work and LOTO environment is essential.
