How to test the air volume of the Ball Mill


How is the air volume generated during the use of the Ball Mill tested? Is there a law to accurately test the air volume? These problems are of concern to many Ball Mill suppliers. Shanghai Shibang passed a year-on-year test and asked the Wind Research Institute to summarize a method for testing the air volume of Ball Mills.

The Ball Mill is selected by the wind. The air volume of the fan is relatively important. The air volume is tested to familiarize with the performance of the equipment. It is very helpful for production and operation. It can avoid the use of Ball Mills and Some common faults.

The air volume of the Ball Mill is derived from the main fan. The power of the fan is slightly less than the power of the main engine. The wind speed is generated by the speed of the impeller. The air volume enters the grinding machine through the pipeline, blows away the crushed material, and then has a cyclone separator. The recovery of the amount of tail air re-enters the grinding chamber. The dust collector acts as a container for collecting the residual air, which not only removes the fine dust, but also acts as a cyclone.

Air volume test formula: main fan air volume & asymp; cyclone air volume + residual air volume, dust collector air volume can be ignored.

Let’s take a look at the working principle of the Ball Mill. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force. The material is sent by the blade to the middle of the grinding roller and the grinding ring. Under the action of the fan, the powdered material is blown up through the analysis machine, and the material that meets the fineness requirement passes through the analysis machine, and the heavy grinding chamber that does not meet the requirements continues to be ground, and the material of the analysis machine is passed. The cyclone is separated and collected. In the grinding chamber, due to the certain moisture content of the material to be ground, the heat generated during grinding causes the gas in the grinding chamber to evaporate to change the gas flow rate, and the connection of the pipes of the whole machine is not tight, so that the outside air is sucked in, so that the circulating airflow increases, resulting in milling The machine has less powder or even blasting machine. In this regard, the Ball Mill has been equipped with explosion-proof measures on the upper part of the machine body, which can largely avoid the accidental injury caused by the explosion of the Ball Mill. At the same time, this situation can also be passed. Adjust the residual air duct between the fan and the main engine to achieve the balance of the airflow, and introduce the excess gas into the small cyclone collector, collect the fine powder brought into the residual gas, and then discharge the exhaust pipe from the upper part of the small cyclone collector. Into the atmosphere, or into the dust collector to purify the exhaust air, however, the technical requirements of the operator is relatively high, and need to be discovered and adjusted in time.

Through the understanding of the air volume of the Ball Mill, the rational use of the Ball Mill can effectively increase the productivity and efficiency, and create more benefits for the users.
