Micum Drum is a specialized laboratory testing apparatus functions according to testing frameworks of IS 1354, used to evaluate the mechanical strength, abrasion resistance, and impact degradation of metallurgical coke. This standard test is crucial in the steel and iron-making industries to ensure that coke will not break down into excessive fine particles during handling and inside blast furnaces. This testing procedures for determining the Micum index (M₄₀ and M₁₀) and half-Micum index of metallurgical coke.

Equipment Specifications (IS 1354 / ISO 556)

• Drum Dimensions: An internal diameter of 1,000 mm and a length of 1,000 mm (or 500 mm for the Half-Micum test apparatus).
• Rotation Speed: Precisely calibrated to run at 25 RPM (rotations per minute).
• Test Cycle: Operates typically for 100 revolutions to test abrasion and impact degradation resistance using a standard 50 kg (or 25 kg) coke charge.
• Associated Standards: Closely aligned with international guidelines under ISO 556. Related specifications for industrial coke grading and sampling context are covered under IS 439.
