SUPPLYING THE BACKBONE OF CEMENT & LIME — HIGH-DURABILITY MULLITE BRICKS FOR ROTARY KILNS

LINING PERFORMANCE THAT DRIVES PRODUCTION EFFICIENCY

Cement and lime plants operate in some of the harshest thermal and mechanical environments in industry. Rotary kilns, coolers, and preheaters are subjected to intense temperatures, abrasive feedstock, chemical attack, and continuous operation. In this environment, refractory failure means more than downtime — it means compromised clinker quality, increased energy costs, and lost revenue.

That’s why DGC Refractories supplies multi-layer composite mullite bricks and shaped refractory products specifically engineered for cement and lime rotary kilns — providing long-lasting protection where it matters most.

OPTIMISED FOR KILN LINING EFFICIENCY

Our high-performance mullite bricks feature:

·       Low thermal conductivity, reducing shell temperature and heat loss

·       Excellent thermal shock resistance, withstanding rapid temperature fluctuations during shutdowns and restarts

·       Superior mechanical strength, preserving lining integrity under high rotational stress and abrasion

·       Dimensional consistency, enabling tight joint construction and smoother installation

These properties not only enhance operational reliability but also contribute to lower fuel consumption, longer campaign life, and improved clinker output stability.

SUPPORTING THE FULL CEMENT LIFECYCLE

DGC Refractories supports cement and lime producers across the full furnace lifecycle:

·       Material selection support, including profile matching for the burning zone, transition zone, and cooler areas

·       Technical audits and failure analysis, drawing on decades of field experience

·       Installation coordination, in collaboration with clients or trusted contractors

·       Post-installation follow-up, to track wear patterns and improve future designs

Our team understands that every kiln is different — which is why our solutions are tailored, not standardised.

A REGIONAL LEADER IN CEMENT INDUSTRY SUPPORT

With a long track record of working with cement producers across South Africa, Zambia, Zimbabwe, DRC, Kenya, Tanzania, Nigeria, and the broader Sub-Saharan African region, DGC Refractories is well-positioned to meet the growing demands of both large-scale cement groups and independent lime producers.

Whether it’s:

·       Servicing a burning zone at a major plant in North-West Province, South Africa

·       Supporting shutdown turnaround in the Copperbelt

·       Or delivering precision brick packages to East or West Africa

We offer the technical experience, logistics reliability, and material quality to get the job done right — the first time.

FUTURE-READY MATERIALS FOR A LOWER-CARBON INDUSTRY

As the cement sector seeks to reduce emissions and improve thermal efficiency, refractory innovation will play a key role. Lining solutions that retain heat longer and extend intervals between relines will help drive both sustainability and profitability.

DGC Refractories is ready to partner with producers across Africa to support this transition — with materials that deliver real-world results.

LET’S BUILD LINING STRATEGIES THAT LAST

For cement and lime producers across Africa seeking to reduce downtime, enhance energy efficiency, and prolong the lifespan of their rotary kilns, DGC Refractories offers more than just supply — we deliver a performance-driven partnership.

Over a Century of Trusted Service — Committed to Safety, Quality, and On-Time Delivery.
