| 1 | Production Capacity | Check whether the proposed kiln, grinding, and material-handling systems match the required annual output and product mix. | Require a mass-balance calculation based on the target capacity, operating hours, raw-material moisture, and expected equipment availability. | Guaranteed capacity, process flow diagram, mass balance, and reference project with similar feed materials. | 15% |
| 2 | Process Technology | Compare dry-process technology, preheater and precalciner configuration, kiln arrangement, clinker cooling, and cement grinding methods. | The process should be selected according to raw-material characteristics, fuel availability, product specifications, and local environmental requirements. | Process description, energy model, raw-material test results, and documented performance data from comparable installations. | 15% |
| 3 | Energy Efficiency | Evaluate thermal fuel consumption, electrical power consumption, heat recovery, and the efficiency of grinding and conveying systems. | Compare fuel consumption in GJ per tonne of clinker and electricity consumption in kWh per tonne of cement under clearly defined operating conditions. | Energy guarantees, calculation assumptions, equipment efficiency curves, and commissioning test procedures. | 12% |
| 4 | Equipment Quality | Assess the design life, material grades, machining accuracy, welding standards, inspection procedures, and critical spare parts. | Critical rotating and high-temperature components should have documented inspection plans, traceable materials, and defined replacement intervals. | Quality-control plan, material certificates, factory acceptance test records, drawings, and maintenance manuals. | 12% |
| 5 | Automation and Control | Compare process instrumentation, centralized control, alarm management, trend recording, remote diagnostics, and operator interfaces. | The control system should provide real-time monitoring of temperature, pressure, flow, vibration, emissions, and key quality indicators. | Input/output list, control architecture, cybersecurity provisions, training plan, and backup strategy. | 10% |
| 6 | Customization Capability | Determine whether the supplier can adapt the layout, equipment sizing, fuel system, raw-material preparation, storage, and product-handling sections. | Customization should be based on site surveys, laboratory testing, local climate, utilities, regulations, and future expansion plans. | Site-specific technical proposal, layout drawings, utility list, design assumptions, and change-management procedure. | 10% |
| 7 | Environmental Performance | Review dust collection, nitrogen oxide control, sulfur and volatile compound management, noise control, and continuous emissions monitoring. | The design should meet applicable local limits and include appropriately sized filters, monitoring instruments, and maintenance access. | Emissions calculations, filter specifications, compliance matrix, monitoring plan, and operating-cost estimate. | 10% |
| 8 | Installation and Commissioning | Compare engineering support, civil-interface requirements, installation supervision, commissioning procedures, and performance testing. | The contract should define milestones for design approval, delivery, cold testing, hot commissioning, trial production, and final acceptance. | Project schedule, responsibility matrix, commissioning checklist, acceptance criteria, and delay provisions. | 6% |
| 9 | After-Sales Service | Assess spare-parts availability, technical response time, staff training, preventive maintenance support, and long-term service coverage. | Service terms should specify response times, spare-parts lead times, warranty coverage, training hours, and escalation procedures. | Service-level agreement, spare-parts list, warranty terms, training scope, and support contact structure. | 5% |
| 10 | Total Cost of Ownership | Compare the complete investment, installation costs, energy use, maintenance, consumables, labor, downtime risk, and expected service life. | Use a lifecycle-cost model covering at least the initial investment, projected operating costs, planned maintenance, and major replacement items. | Itemized quotation, operating-cost assumptions, maintenance schedule, consumables forecast, and payment milestones. | 5% |
