Production Process introduction

Production process description
1. Raw material feeding
The limestone in the plant yard will be carried by tractor shovel and feed to hopper, it will be discharged from hopper to vibrating feeder and sent to vibrating screen for screening through belt conveyor. The size a Y 20mm will be sent to pre-heater by conveyor. And size less < 20mm will be carried away.
2. Calcination
The limestone in the pre-heater will be preheated by the hot air, then it will be discharged to rotary kiln though chute that connecting pre-heater and kiln, it will stay in the kiln for 1.5-2 hours for calcination, during the process, it will be calcinated with a temperature around 1300 degrees Celsius, limestone decomposition, release of CO2, become quicklime. Then the lime moves to vertical cooler for cooling.
