INTRODUCTION

Among all the active lime production process, the rotary kiln production process is the most advanced one. Our production process adopt the rotary kiln with the vertical preheater and vertical cooler for the limestone calcination to achieve the production requirements of energy saving, environmental protection, the high activity. We can provide technological solutions and complete production equipment for 50-800TPD quicklime (active lime) production line.

FEATURES

1. The combustion equipment uses energy-saving burners to automatically control the air distribution volume to reduce the loss of incomplete fuel combustion.

2. Rotary kiln refractory bricks adopt light-weight insulation on the outer layer and composite bricks with refractory and wear-resistant inner layer to reduce heat dissipation from the outer skin of the rotary kiln.

3. There is a vertical preheater at the end of the rotary kiln, which makes full use of the high-temperature flue gas produced by the combustion of the rotary kiln to preheat the materials in the preheater, so that the materials are partially decomposed in the preheater.
