HTNJ-6 Caking Index Tester is a specialized instrument for determining the caking capacity of bituminous coal and other coking materials, including the Roga Index (R.L.), Coke Residue Drum Index (J.Z.Z), and Caking Index (GRL). It is widely used in coal, metallurgy, coking plants, research institutions, and universities to evaluate the caking properties of bituminous coal. This instrument is an ideal tool for rational utilization of coal resources and energy conservation.

Working Principle & Structural Features:

• The tester consists of a motor, reducer, rotating drum, counter, and housing.
• The motor drives two drums at a speed of 50±2 r/min via a worm gear reducer, subjecting coal samples and coke blocks to strength tests. The wear resistance of the coal blocks reflects their caking capacity.
• Equipped with an electronic counter for precise counting and user-friendly operation. Supports customizable rotation counts (1–999 turns) and auto-shutdown.
• Complies with the national standard GB 5447 “Method for Determination of Caking Index of Bituminous Coal.”

Technical Parameters:

• Rotation Speed: 50±2 r/min
• Rotation Range: 1–999 turns (adjustable)
• Display: LED digital readout | Manual/auto reset
• Power Supply: AC 220V±10%, 50Hz
