Cement production method       The production process of cement is simply two grinding and one sintering, that is, raw materials are mined, crushed, ground and mixed to produce raw materials. Raw materials are fired at 1450 ~ C high temperature to produce clinker. Clinker is crushed and ground together with gypsum or other mixed materials to become cement. Due to the difference between dry and wet raw meal preparation, the production methods are divided into three types: wet process, semi dry process or semi wet process and dry process. 幻灯片3 Characteristics of wet process producti...

In 2015 overall economic situation fell significantly, cement industry profits fell to the bottom, in order to use "The Belt and Road" and overseas layout to achieve bottoming out, each cement plant will save production costs and the introduction of green environmental protection equipment as the primary bargaining chip. In the process of cement production, cement clinker, materials, slag can be used after grinding, however, the results show that the best grinding efficiency can be achieved only by different materials separately. 1.      General situation of "one grinding a...
