About CJO Technologies
Our Expertise
At CJO Technologies Ltd., founder Christopher Oldroyd brings his specialist engineering expertise as a Chartered Engineer (CEng) to the challenging and transformative fields of high-temperature processing and pyrometallurgy. With decades of hands-on experience, he partners directly with clients across the metals, minerals, and advanced materials sectors, offering dedicated design and analytical services to develop, optimise, and implement robust thermal process solutions. The consultancy provided by Christopher Oldroyd encompasses the full project lifecycle, from initial process conceptualisation and Front-End Engineering Design (FEED) studies, through to intricate detailed equipment design using advanced 3D CAD, rigorous Finite Element Analysis (FEA) for structural and thermal integrity, and Computational Fluid Dynamics (CFD) for process simulation and optimisation. He takes personal pride in translating complex chemical and physical transformations into practical, efficient, and reliable engineered systems.
Leveraging his deep, first-hand expertise, Christopher Oldroyd delivers bespoke designs through CJO Technologies Ltd. for a comprehensive range of critical pyrometallurgical and thermal processing equipment, tailored to meet specific operational and material challenges. His design portfolio, built on years of successful project execution, includes innovative solutions for;
- Top Blown Rotary Converters (TBRCs) for applications such as PGM recovery from spent autocatalytic convert and Cu and PMs from WEEE,
- Short Rotary Furnaces (SRFs) for applications such as lead recycling
- Rotary Kilns for diverse thermal duties
- Static refining vessels such as Lead Refining Kettles
- Oxy-fuel burners and combustion systems
- Electric element heating systems
Christopher's capabilities further extend to providing detailed engineering for crucial ancillary systems, such as sophisticated molten metal or material handling solutions, robust off-gas treatment plants to meet environmental standards, and the integration of essential control and automation philosophies to ensure safe and optimised plant performance.
