Active Lime Production Line--Shanxi 200,000TPA Lime Renovation
Plant
Brief Introduction
Country: China
Project: 200,000TPA lime renovation plant.
Equipment: Rotary kiln, vertical pre-heater, bag filter, etc.
Application: for steel industry
Project 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. The lime will
be sold to Shanxi, Neimeng Province. In recent years, Chinese
government have strict request in environment protection and also
affected by economy crises and lower production cost, the owner
management team decide to adopt advance rotary kiln for calcination
lime. 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.
5. pre-heater and hopper adopt steel structure. This make whole
plant look nice and efficient.
6. This design obey the regulations in environment, fire control,
labor safety.
Project Implementation
After signing contract, our company R&D center have made a
survey of worksite and made feasibility study report and primary
design. After discussion with owner in July, the final construction
solution is confirmed. As this plant locates in alpine region, it
enters frost period in December, so the construction period is only
4 months. our company focus all strength on this construction
implementation schedule. Construction is executed with design. With
strong support of owner, the project start fire on November 20.
After 20 days test, every system run all right and plant start
production. Our high efficiency get high praise and approval from
owner.
