Harden Unveils Three Low-OPEX Alternative Fuel Solutions to Boost Cement Kiln TSR
From July 29 to 30, 2026, the 15th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference is being held in Wuhu, Anhui. Focusing on carbon reduction, cost efficiency, and digital intelligence, the event explores practical pathways for the cement industry to navigate the dual-carbon era.
As a pioneer in solid waste resource utilization, Harden is showcasing three low-OPEX alternative fuel (SRF/RDF) preparation solutions at the event. Designed around the core objective of delivering a "lower cost per ton and higher competitive advantage," these end-to-end processing lines cater to cement plants with varying capacities, raw materials, and space constraints, directly driving up the Thermal Substitution Rate (TSR) in cement kilns.
Covering processing capacities from 50 to 600 tons per day, Harden's portfolio addresses every scenario—from rapid deployment to large-scale, premium fuel production.
Solution 1: SG3000MP One-Step Shredding System (TSR 20–35%)
Target Application: Small to medium SRF plants (Capacity: 50–200 t/d)
System Highlights: Addressing pain points like limited space, restricted power supply, and complex material inputs, Harden pioneered this one-step solution. A single shredder replaces traditional multi-stage setups. With a footprint of just 105 m² (an 82% reduction compared to traditional lines), it is highly highly suitable for retrofitting small plants or restricted-space projects.
Core Value: Rapid deployment and the optimal choice for space-limited scenarios.
Solution 2: DDS Three-Stage Shredding System (TSR 30–55%)
Target Application: Large-scale SRF production centers (Capacity: 300–500 t/d)
System Highlights: Designed to handle complex waste streams, including textiles and tangling materials that are typically difficult to process at scale. Utilizing "step-shredding + AI cooperative control" technology, it adapts to 95% of common raw materials. The system guarantees that 95% of the output fuel is ≤80mm, ensuring the high uniformity required to prevent kiln blockages and maximize burnout rates.
Core Value: High-capacity, standardized fuel production for hard-to-shred and complex materials.
Solution 3: DSWS High-Quality Alternative Fuel System (TSR 40–90%)
Target Application: Premium SRF projects demanding high substitution rates and large-scale utilization.
System Highlights: Standard mixed waste often contains soil, inert materials, and impurities that lower calorific value and increase harmful emissions. Harden’s DSWS employs a refined closed-loop process (Pre-shredding → Sizing/Screening → Air Separation → Fine Shredding) to systematically extract impurities. This maximizes the fuel's heating value and minimizes harmful elements, allowing cement plants to safely achieve a high TSR and capture greater carbon reduction benefits.
Core Value: High-value, high-standard, high-TSR fuel extraction from heavily mixed waste streams.
Evolving from traditional high-energy, rough-shredding lines to today's modular, intelligent, and low-cost systems, Harden continues to innovate based on actual industry bottlenecks.
Backed by 16 years of global project experience, Harden's three differentiated low-OPEX solutions precisely address the full spectrum of cement plant requirements, driving the synergy of energy conservation, waste valorization, and economic profitability.
