    The liquid which is the melting of 50% volume of iron ore particle and 55% volume of limestone particle produces the liquid film around particles and the burning of 45% of limestone and 100% of coke particles creates the void among particles in the melting zone.

  • The influence of petrography, mineralogy and

    2017-12-5 · The Neoarchean limestone from the Ouplaas Mine is very much sensitive to high burning temperatures showing an unusual and drastically pronounced sintering or overburning tendency. Especially, burnt lime presents a high reactivity at 1050 °C (t60 = 1.5 min., Tmax = 70 °C), but it rapidly decreases at 1150 °C (t60 = 9 min., Tmax = 65 °C).

    2013-12-1 · Sintering (post-calcination process) is performed at a temperature below the melting point of the desired phase in order to improve crystal quality by minimizing defects, enhance grain growth

  • Light Burning Condition of Preparing Dolomite Clinker

    The influence of the light burning temperature on the sintering property of nature dolomite has been investigated by two-step sintering process in the temperature range 1500 °C to 1600 °C. The resulting bulk densities and apparent porosities of the sintered dolomite samples were examined, and analyzing the sintered dolomite by scanning electron

  • Combustion in bubbling fluidised bed with bed

    2006-10-1 · Abstract. A bed material of limestone was used in order to reduce/eliminate the tendency for bed material agglomeration and sintering that normally occurs in plants that operate with the traditional silica bed material. Combustion tests were carried out in

  • Sintering Process Carmeuse

    2021-5-24 · Burnt lime, as compared to limestone, improves the heat transfer in the sintered layer. At the same basicity and the same volume of fuel, a change in the CO 2 /CO ratio can occur, due to the different amounts of carbonates after their replacement by lime. For lime too, the quality, granulometry, quantity, and method of lime addition to the agglomeration process are critical to sinter performance and
