Colored Limestone
Product Detailed
1.The content of CaO is over than 55%. 2.the size can be 0-4mm,20-40mm,40-80mm,80-120mm, 3.or 0-120mm due to your requirement

1,Limestones should consist as far as possible of very fine calcite crystals. Coarse-crystal calcite (e.g. spar) as a rule leads to disintegration of the stone during burning. Broken quicklime fragments uncontrollably alter the air resistance of the feed, complicate kiln management and impair the quality of the quicklime.

 

2,During calcination, CO2 must be able to exit freely from the limestone in order to obtain complete decompostion of the stone. If limestone are coated with mud or clay, a vitreous sinter skin may form around the pieces during burning, hindering or preventing escape of the CO2. Hence only clean or washed limestones should be used.

 

3,Our limestone with high Cao content is superior than any other manufacturers' in Yangtze river.
