The grinding faces are so arranged on the bars that only one is in grinding relation with the periphery of said roll; the other face being so spaced as to act as a furrow. The bar is reversible so that the face forming the furrow becomes the grinding face and vice versa.- The uppermost of these grinding blocks is corrugated coarsely, theRead More
The combination of hydrodynamic and hydrostatic spindle lubrication means that the machine benefits from the advantages of both lubrication systems. The advantage of the hydrostatic part is that it prevents metallic friction, especially during the initial and final stage of the grinding spindle operation. The hydrodynamic lubrication produces an oil pressure of 750 bars, which would be impossible to reach with hydrostatic lubrication. This ensures that the grinding spindle is always positioned right in the centre of the rotation axis/bearing axis, regardless of load conditionsRead More

Cement production, which is highly dependent on the availability of natural resources, will face severe resource constraints in the future. This is especially true for the cement industry in China. Thus, the industry is focusing on reducing the consumption of natural resources at both the manufacturing and operational stages. The aim of this article is to improve the management of resources used in the cement production process and mitigate their environmental effects. First, material flow routes for the cement manufacturing process are established, after which three mass balances are built during the three production stages using actual plant data received from an existing cement manufacturing facility. Finally, the material efficiency of the units and stages as well as the waste recycle rates during these stages is calculated. The results show that approximately 2.48 t, 4.69 t, and 3.41 t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages, and their waste rates are 63.31%, 74.12%, and 78.89%, respectively. The recycling rate of wastes during clinker production is remarkably higher than those during other manufacturing stages, wherein waste gases are directly discharged into the atmosphere. The material efficiency values for a raw mill, pyro-processing tower, rotary kiln, clink cooler, and cement mill are determined to be 36.69%, 34.24%, 39.24%, 29.76%, and 25.88%, respectively, whereas the waste recycling rates for these units are found to be 16.33%, 81.98%, 100.00%, 99.53%, and 0.00% respectively. These results will provide researchers with knowledge regarding the effectiveness and efficient use of natural resources in the cement sector. These important findings can also be used to influence the development of national and industrial policies in relation to the goal of achieving sustainable development in the cement industryRead More

With regards to the steel material steel, the development of the microstructure during rolling is complex and involves static and dynamic re-crystallization of austenite. From a practical point of view, the austenite grain size distribution in the rolled product is of paramount importance in controlling mechanical properties. In the roughing and intermediate stages of the rolling mill, the stock is moving slowly between the stands, such that the material has a chance to ‘normalize’ itself as a result of recovery and re-crystallization. During the finishing rolling stage, the stock is traveling at a high speed between closely spaced stands and consequently, and does not have adequate time to normalize. This lack of normalization can have a significant effect on the final microstructure and mechanical properties of the rolled productRead More
