EXPERIMENTS IN DEAD‐BURNING DOLOMITE AND …

Stability of calcined dolomite; effect of fineness of raw material, nature of flux and temperature of burning.—Dolomite is difficult to dead-burn because the absorption of moisture from the air produces a gradual slacking due, probably, to the hydration of lime and various lime compounds, and this tends to cause disintegration.With all the fluxes tried, 100 mesh raw material gave …

Calcination of Limestone – IspatGuru

2013-5-2 · Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.

Kaolin vs Calcium Carbonate

Kaolin and calcium carbonate are both used as fillers or extenders, in other words they make something cheaper adding them the volume goes up and the cost per ton goes down. What music to our ears! But add too much filler and you start to lose good properties, so it is always a trade-off of cost versus quality.

Calcined Dolomite

Notes. Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which provides an buffering because MgO …
