SH Scientific’s Pilot-Scale Rotary Kiln: Precision Thermal Processing for Advanced R&D

A Pilot-Scale Kiln Bridging Lab and Industry

Ideal Use Cases in R&D and Process Development

This pilot rotary kiln delivers real-world utility across a range of research and development applications. Its versatile design makes it invaluable for:

• Advanced Materials Research: Developing and testing novel materials (e.g. nanomaterials, composites, rare earth compounds) under continuous high-temperature conditions. The kiln supports complex thermal processes like calcination, pyrolysis, and solid-state synthesis crucial for cutting-edge material science.
• Ceramics Process Development: Refining firing cycles and sintering processes for technical ceramics and refractories. The kiln’s precise control enables researchers to optimize ceramic properties at pilot scale before scaling up to production.
• Battery Materials & Recycling: Processing cathode/anode powders and recycling battery waste in controlled atmospheres. For example, the kiln can perform pyrolysis for battery recycling and calcination for new battery material synthesis with high uniformity, aiding development of next-generation batteries and sustainable recycling methods.
• Catalyst & Specialty Chemical Production: Thermal treatment of catalyst supports, molecular sieves, or specialty chemical powders. The continuous rotary system provides uniform heating for catalyst activation, regeneration, or chemical precursor calcination, ensuring consistent product quality in process development.
• Powder Metallurgy & Metal Oxides: Oxidation, reduction, or sintering of metal powders and oxides under tightly controlled temperatures and atmospheres. The pilot kiln’s capabilities in powder processing help metallurgists fine-tune processes for powders and advanced alloys prior to industrial production.

By accommodating these use cases and more, the SH Scientific pilot kiln serves as a multi-purpose platform for R&D in materials science, chemical engineering, energy storage, and beyond. It is even being leveraged in emerging research like low-carbon cement production and biomass pyrolysis, reflecting its broad applicability to modern industrial challenges.

Advanced Technical Features and Design

At the heart of this pilot-scale kiln is an array of sophisticated engineering features that ensure high performance and flexibility for researchers:

• Stainless Steel Rotary Tube with Internal Baffles: The kiln’s process tube is fabricated from durable 310S stainless steel (approximately 267 mm outer diameter) to withstand repeated heating cycles up to 1000 °C. Uniquely, SH Scientific integrates internal baffles inside the rotating tube – a feature rarely seen at this pilot scale – which promotes consistent tumbling of the material and even heat exposure throughout the load. This innovation improves thermal uniformity and processing consistency, giving researchers confidence that every particle experiences the same conditions.
• Eight-Zone Temperature Control for Uniformity: The pilot kiln is divided into eight independent heating zones, each with its own precise temperature controller. This multi-zone design enables exceptional thermal uniformity along the length of the tube as well as the ability to program temperature profiles (gradients or step changes) to suit specific processes. With a maximum temperature of 1000 °C in each zone, users can closely replicate industrial thermal conditions at pilot scale. The result is improved process fidelity – critical parameters like reaction completion, phase formation, or sintering density can be optimized and reliably scaled up.
• Continuous Operation and Custom Configurations: Unlike simple batch furnaces, SH Scientific’s rotary kiln supports continuous operation with a feeder and discharge system, allowing longer experiments or small-scale production runs. The design includes options like adjustable rotation speed and tilt angle to control material residence time, as well as gas inlet/outlet ports for reactive or inert atmospheres. Moreover, SH Scientific offers extensive customizability to meet each client’s unique requirements. Whether a project calls for special atmosphere control (e.g. vacuum or controlled gas environments), enhanced exhaust filtration for volatile byproducts, or tailored material handling (such as custom feed hoppers or discharge collectors), the engineering team can modify the system accordingly. This willingness to customize ensures the kiln can be adapted for diverse sectors and novel processes.
