建筑石膏粉生产线

Building gypsum production line

　　化学石膏（脱硫石膏，磷石膏，柠檬石膏等）是我公司今年来的工艺，装备研发的重点项目，经过5年来的工艺技术储备和二十几个工程实例的建设实践，工艺技术和装备技术方面日趋完善，已经建设完成的生产线总处理量达到150万吨，走在了国内同行业的前列。

Chemical gypsum(mainly desulfurization gypsum and phosphogypsum)will be one of the main gypsum building materials from now on and our technology has foccused on it recent years. After 5 years technical strorage and building experience of more than 20 projects, our process technology and equipment technology are oerfect day by day and our total output for every year of finished production lines has reached 1.5 million tons, at the fore front of civil industry.

　　在建筑石膏生产工艺上，根据客户热源，原材料，占地，产品要求等基础参数不同，我们可以为客户提供一步法和两步法两种生产工艺，在两种工艺上，又可根据用户生产产品的不同分别采用石膏煅烧沸腾炉，锤式煅烧机，锥形炒锅等多种不同的石膏煅烧设备，以生产出最适合用户要求的建筑石膏，克服了国内煅烧设备单一造成的产品可调性能差的特点。

We can supply two production process, one-step and two-step production process, according to customers’ different sources of heat, raw material, plant area, product requirements and etc…And also we can supply different calcination equipments according to customers’ different products, such as gypsum-calcining boiling furnace, hammer type calciner, cone-shaped popper and ect. In order to produce most suitable gypsum powder for customers, which overcomes bad performance characteristics of the products because of the single calcination equipment.

　　我们可以为客户提供工程设计、设备制造、安装、调试、人员培训到包投产的一揽子服务，可为客户提供交钥匙工程。

We can offer our clients a set service of design, many  equipment manufacturing, installation, commissioning,training and putting into operation, as well as turn key project.

 　　建筑石膏生产线（天然石膏）采用立式磨、沸腾炉等国内成熟先进的工艺装备，其中沸腾炉为目前我国应用最广的建筑石膏煅烧设备，具有设备小巧，生产能力大结构简单，不易损坏设备紧凑，占地少能耗较低操作方便，容易实现自动控制，产品质量好，熟石膏相组成比较理想，物理性能稳定基建投资省，运行费用低等七大优点，被广泛应用于天然石膏和化学石膏的煅烧工艺之中，并随我公司生产线远销到泰国、乌兹别克斯坦、哥伦比亚、墨西哥等世界上多个国家。

Gypsum Powder Production Line (natural gypsum) adopts civil advanced process  and equipments like Vertical Mill, Boiling Kiln and so on, of which Boiling Kiln is the most widely used calcining equipment at present in China with the advantages of small size, fine producing capacity, simple structure, small occupied areas, low energy consumption, convenient operation, automatic control, good quality, ideal phase composition, steady physical performance and low investment, etc.. It is widely used into calcining process of natural gypsum and chemical gypsum and has been sold to THAILAND, UZBEKISTAN, COLUMBIA, MEXICO and etc..

　　双桨叶干燥机可对膏状、颗粒状、粉状、浆状物料间接加热或冷却，可完成干燥、冷却、加热、灭菌、反应、低温燃烧等单元操作。空心轴上密集排列着特殊的楔型中空搅拌传热桨叶，热介质经空心轴流经桨叶具有较高的传热效率和传热面自清洁功能。单位有效容积内传热面积很大，热介质温度从-40℃到320℃，可以是水蒸汽，也可以是导热油等。间接传导加热，没有携带空气带走热量，热量均用来加热物料。热量损失仅为通过器体保温层向环境的散热。

　　流化煅烧机设备,主要用于将吸附水含量小于5%的天然二水石膏粉或化学二水石膏粉转化为半水石膏,是一种应用流体化技术煅烧石膏的高效专用设备.

沸腾炉的工作原理

　　在正常工作时炉子装满粉料,炉底部通过气体分布板吹入少量空气,使粉料实现流态化.热源的热量通过加热管的管壁传给物料.生石膏粉连续不断地加入,与床层中原有的大量热石膏粉迅速混合,达到同样的温度(140-150℃).此温度处于二水石膏激烈脱水转化为半水石膏的温度范围.

　　因此生石膏就迅速开始脱水.在主炉中大部分二水石膏转化为半水石膏.物料进入付炉后,温度迅速升高到155-165℃,残余的二水石膏全部转化为半水石膏,并有少量开始向无水石膏Ⅲ转化.这时物料从付炉床层上界面处溢流出料.
