To Analyze the State of Motion of Materials

In recent years, many experts have studied the motion state of the materials in the Rotary kiln . The rotary kiln is one of the most common machines used in mining machinery. As a result, the study on the motion state of the materials in rotary kiln has great significance. The experts of Henan Hongxing Mining Machinery think that the motion state of the materials in the rotary is related to the size and the rotating speed of the rotary kiln. We can get the critical speed of revolution of the materials in each state status under different test conditions through the calculation of the criterion number. In order to reduce the power consumption of the materials in the kiln body, we must choose the critical point in certain rank.
In the engineering practice, backfall and tumble with low speed of the materials in the rotary kiln often appear under different operating conditions of rotary kiln. The other state modes have higher requirements on the rotating speed of the rotary kiln, which may endanger the operational safety of the rotary kiln drive for the large-scale industrial rotary kiln. In addition, the power consumption to drive the rotary kiln is large. Therefore, for the industrial rotary kiln in the actual operation, the centrifugal movements are not used. Since the tumble movement can better make the materials fully contact with the air in free space and improve the gas-solid reaction efficiency, the tumble is the best motion state for the materials in the rotary kiln. In addition, the operation of the tumble movement is stable as the rotary kiln, which can reduce the energy consumption of the rotary kiln. So far, almost all the test studies and the model studies about the materials in the rotary kiln are carried out based on the tumble bed.
The study on the motion state of the materials in rotary kiln is very important for the better practical use of the rotary kiln. Only we have a better understanding about the rotary kiln can we use it to create more profits for us.
