The Cyberabad Traffic Police issued a traffic advisory as road works begin for the laying of a cement concrete (CC) road from Jaya Shankar Statue to RRR Restaurant at Parvathnagar in Madhapur limits. The advisory indicated that traffic diversions will be in place for 30 days from May 16 to ensure the smooth flow of vehicles and to minimise congestion on the affected stretch. The measure aims to balance uninterrupted construction activity with the movement needs of commuters.

Traffic moving from Toddy Compound towards Parvathnagar village will be diverted at Parvathnagar junction towards Sunnam Cheruvu and the 100 feet road. Local motorists and public transport operators have been advised to follow the diversionary route as directed by traffic personnel on duty. Alternate routes and signage have been planned to mitigate delays and to manage peak hour congestion.

Police officials said the diversion had been planned to facilitate uninterrupted road works while maintaining traffic movement in the area. Commuters were urged to plan their travel accordingly and to cooperate with traffic staff managing the stretch. Authorities indicated that enforcement of diversions would be active and that violations could attract penalties.

The 30 day schedule is intended to allow contractors to complete the laying and curing phases with minimal interruption to vehicular flow. Residents and businesses in adjacent localities have been advised to factor the diversion into deliveries and travel plans. The traffic police promised continuous monitoring of the works and the operational diversions and emphasised that temporary inconvenience was necessary for longer term improvement of the road network. Traffic personnel will be stationed at key junctions and additional signage and temporary markings will be displayed to guide motorists and pedestrians through the revised alignments while public transport services will follow the diversion where feasible and operators have been asked to adjust timetables to minimise disruption.

The new solution promisescontinuous, real-time tertiary air flow measurement in cement plant operations.

PROMECON GmbH has launched the McON IR Compact, an infrared-based measuring system designed to deliver continuous, real-time tertiary air flow measurement in cement plant operations. The system addresses the longstanding process control challenge of accurate tertiary air monitoring under extreme kiln conditions. It uses patented infrared time-of-flight measurement technology that operates without calibration or maintenance intervention.

Precise tertiary air measurement is a critical requirement for stable rotary kiln operation. The McON IR Compact is engineered to function reliably at temperatures up to 1,200°C and in the presence of abrasive clinker dust. Its vector-based digital measurement architecture ensures that readings remain unaffected by swirl, dust deposits or drift. Due to these conditions conventional measurement systems in pyroprocess environments are often compromised.

The system is fully non-intrusive and requires no K-factors, recalibration or periodic readjustment, enabling years of uninterrupted operation. This design directly supports plant availability and reduces the maintenance overhead typically associated with process instrumentation in high-temperature zones.

PROMECON has deployed the McON IR Compact at multiple cement facilities, including Warta Cement in Poland. Plant operators report that the system has aided in identifying blockages, optimising purging cycles for gas burners, and supplying accurate flow data for AI-based process optimisation programmes. The practical outcomes include more stable kiln operation, improved process control, and earlier detection of process disturbances.

On the energy side, real-time tertiary air data enables reduction in induced draft fan load and helps flatten process oscillations across the pyroprocess. This translates to lower fuel and energy consumption, fewer unplanned shutdowns, and a measurable reduction in NOx peaks. This directly reflects on the downstream cost implications for plants operating SCR or SNCR systems for emissions compliance.
