 Limestone deflagration in a rotary kiln Article

This calcinations technology features low energy consumption and high output, and after lacks and decarburization and briightening, the products have stable performance and can be utilized in such commercial fields as paper making and coating. Commonly known as rotary kiln, it is additionally called rotary dryer, belonging to construction products. Depending on the elements, the rotary kiln comes into three types: clinker rotary kiln, limestone rotary kiln and cement rotary kiln.

An experimental study of the calcination of limestone has been accomplished in a remarkably instrumented pilot-scale rotary kiln. Local gas, solids, and wall conditions and pct calcination have been measured under a range of working conditions to determine the influence of limestone type, feed price, rotational rate, inclination angle, and particle size on calcination and heat flow in the kiln. Thus, it is found which the local calcination is dependent mainly on the solids temperature and therefore on high temperature transfer. From the variables studied, the limestone feed price has the strongest effect on the temperature and calcination areas, whereas tendency angle and rotational speed are fairly less essential. The different limestones studied displayed significant variations in heat-absorption potential and feu temperature which can be related to their particular radiative houses. Increasing compound size on the range of 0. 75 to three. 5 mm resulted in an increase in both high temperature transfer to the bed and calcination.

Working Principle with the Limestone Rotary Kiln

The materials being burnt enter the oven from the high end of the cyndrical tube. Due to the slope and gradual rotation in the cylinder, the fabric moves about from top to bottom along the axis to finish its method. At last, the finished materials get into the cooler throughout the burner engine. The gasoline gets into the kiln throughout the head with the kiln. The waste gas will be released from the end of the kiln after swapping heat with all the...
