Country: China
Project: 200,000TPA lime renovation plant.
Equipment: Rotary kiln, vertical pre-heater, bag filter, etc.
Description:
This project locates in Suozhou, Shanxi province. It a private joint-stock company. This project starts production in February 2009. It use vertical furnace for lime calcination.

After huge market research and supplier evaluation, in June 2013, Shanxi JIangqiang Activity Lime Co., Ltd. selected ZK as whole project supplier. Contract convers design, equipments, supervision installation.
Principle of project construction.
1. Adopt advanced, mature, reliable technology and achieve economy recycle and adopt non-waste production technology.
2. Saving land principle. Make layout according to real land situation and make layout sequenced and efficient.
3. Adopt energy saving technology and make full use of heat. We use ZK pantented product gas burner, and this can burn fuel enough.
4. The design have considered dust collect. At dust points, we placed bag filter to deal with waste dust. This make environmental reach national request.
