How to keep the internal ventilation and wind speed control of the ball mill?

　　To keep the use efficiency of the ball mill, not only regular equipment cleaning, but also to master certain wind speed control requirements and internal ventilation at the time of use, and effectively enhance its use efficiency while operating.

　　Let's first understand the importance of ventilation in the ball mill. The air intake of the ball mill is good and the air is directly affected by the grinding efficiency. The ball mill ventilation is that it is in time to discharge the inner fine powder in time to avoid affecting the efficiency of the grinding; the second reduces the internal temperature, avoiding gypsum dehydration tail warehouse. When the material moisture is too large and the mill is extremely ventilated, the grinding is difficult, not only the moist powder adhesion plugs, but also reduces the amount of materials and flow rate in the unit time. At the same time, when these polishing body abrasive materials, since the static electricity is also attached to the formation of the buffer layer, resulting in a substantial impact crushing function of the abrasive body. When the surface of the liner adhesive fine powder thickness is 1 mm, the abrasive body can reduce the material impact force to one-third, which in turn leads to a decrease in milling, and the grinding power consumption is increased.

　　When the energy-saving ball mill is inherently ventilated, the comparative simplicity is added to the upper portion of the gas tube to increase the axial flow fan, and the mill is closed, the discharge slip groove and other parts are closed, preventing damage caused by leakage. Grinder ventilation short circuit. This way, the internal ventilation is smooth, and it solves the grinding problem. Similarly, the locking system must also do well, otherwise the wind turbine is directly exhausted from the dramatic mouth, forming a ventilation short circuit, and there is not much wind in the grind. Second, we need to understand the wind speed inside the control device is also very important. Regarding the choice of grinding air veins, generally, natural ventilation V-0.4 m / sec, strong ventilation V = 0.7 m / sec. Some of the foreign plants believe that the strong ventilation wind speed V should be 0. 9 to 1.0 m / sec. V = 0.7 m / sec, production has no longer increase, so it can be considered v = 0.7 m / sec to wind speed.

　　In the usual we need to periodically maintenance and maintenance of the equipment, it is important to maintain the internal ventilation of the equipment, as this has a great impact on the production of the ball mill. There is also the need to control the air volume inside the device in a reasonable range, too large or too small to meet the requirements.
