Revolutionizing Cement with RDF

Under pressure to meet China’s “dual carbon” goals—reducing carbon emissions and energy consumption—cement producers are embracing RDF to replace coal. 

Unlike traditional fossil fuels, RDF transforms mixed industrial waste into a valuable resource. This not only alleviates landfill burdens but also cuts fuel costs and emissions, aligning with global sustainability trends.

Harden’s advanced RDF preparation system is at the core of this Zhongshan plant, enabling the conversion of complex waste streams into high-calorific-value fuel (4000–5000 kcal/kg), comparable to coal. 

This solution supports large-scale RDF use in cement kilns, delivering both environmental and economic benefits.

Turning Waste into Opportunity

The plant processes a diverse mix of industrial waste—textiles, leather, paper, and plastics—that would otherwise require costly disposal. 

Harden's system employs a sophisticated process of secondary shredding, air separation, and magnetic sorting to produce uniform RDF particles under 50 mm, ideal for cement kiln combustion. This precision ensures stable heat output and high thermal efficiency, critical for clinker production.

The Power of the SG3000 Fine Shredder

Central to the plant's success is Harden's SG3000 fine shredder, engineered for efficiency and durability:

● High Throughput: Processes up to 15 tons per hour, supporting the plant's 100,000-ton annual capacity.

● Versatile Design: Features wear-resistant blades and an optimized shredding chamber, handling tough, mixed waste with minimal clogging, low failure rates, and easy maintenance.

● Superior Output: Delivers consistent particle sizes under 50 mm, ensuring stable RDF quality that meets stringent kiln requirements.

Impact That Speaks Volumes

The cement company’s leadership sees this RDF plant as more than a cost-saving measure—it's a strategic leap toward green production. By producing 100,000 tons of RDF annually, the facility:

● Replaces approximately 67,000 tons of standard coal each year.

● Reduces carbon emissions by nearly 200,000 tons annually.

● Lowers fuel costs by about 15%, achieving a win-win for profitability and sustainability.

Leading the Green Charge

As cement producers worldwide join the shift to low-carbon production, Harden's RDF preparation technology is proving to be a critical enabler. 

This Zhongshan plant demonstrates how industrial waste can fuel a sustainable future, helping cement companies meet energy and carbon control mandates while turning environmental challenges into growth opportunities.
