Cement mill

 Cement mill

cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in cement mill.

cement is grounding very coarsely (typically 20% over 100μm particle diameter) without cement mill until better grinding technology using cement mill became available. Besides producing un-reactive cement with slow strength growth without cement mill, this exacerbated the problem of unsoundness. This late, disruptive expansion is caused by hydration of large particles of calcium oxide. Fine grinding by cement mill lessens this effect, and early cements produced not by cement mill had to be stored for several months to give the calcium oxide time to hydrate before it was fit for sale. the development of specialized steel led to the development of new forms of grinding equipment such as cement mill, the typical fineness of cement by cement mill began a steady rise. The progressive reduction in the proportion of larger, un-reactive cement particles has been partially responsible for the fourfold increase in the strength of Portland cement during the twentieth century. The recent history of the technology has been mainly concerned with reducing the energy consumption of the grinding process by cement mill.

 

        Infrastructure construction makes a contribution to mining machinery industry

With the development of the national infrastructure projects in recent years, China's investment in infrastructure including road construction has stimulated the development of construction machinery industry. It is understood that China had completed the task of 2.5 trillion fixed assets investment , including 800 billion yuan on railway, 1.5256 billion on highway and 0.1458 billion on waterway.

The infrastructure construction is based on the support of gravel aggregate and the input of the cement, while the gravel aggregate and cement production depend on the crushing equipment and cement production line. From a certain point of view, the infrastructure greatly stimulate, promote the rapid development, and bring a new opportunity for the construction machinery industry including the mining machinery industry.

Henan Zhengzhou Unique Group is the appointed manufacture of cement building materials, crushing and screening equipment by National Machinery Industry Ministry, integrating scientific research, design, development, manufacture, sales, installation, test and training services. Crushing and cement production line equipment have good sales in various provinces and regions, have been exported to Russia, Turkey, South America and other countries and regions, which also have received good reputation from customers.
