      The cracking index of iron ore lumps is a critical parameter for the evaluation of its crushing behavior in upper part of blast furnace, which is widely adopted in the pricing of iron ores in international market. The cracking of iron ore lumps is due to rapid evaporation of free and crystal water during heating and also the heterogeneous heating in different parts or lumps, which is very important for the smooth operation of blast furnace. The permeability of burden column in blast furnace may be seriously deteriorated by the powders produced by the crushing of iron ore lumps, and consequently the economic parameters of blast furnace during smelting will be influenced. The cracking property of natural iron ore lump, sinter and pellets for different locations or factories is of significant difference. Hence, the cracking behavior of iron-bearing materials have to be tested before practical application in consideration of economy. This machine is developed based on latest ISO 8371-2007 and GB/T 10322.6 standards.
