How to choose the fan of wood crusher correctly?

If you want to know what kind of fan is suitable for wood grinder, you should first know what kind of fan is used for. Wood crusher is mainly composed of crushing equipment and fan. The fan is one of the most important equipment in the production process of the wood crusher. Its function is to pump the finished products to the collector after the high-speed rotation of the wind blades.

Generally speaking, the wood crusher is usually used by centrifugal fan, it is composed of spindle, impeller, casing, bearing drive organization and motor. According to the principle of converting kinetic energy into potential energy, it uses a high-speed rotating impeller to accelerate the gas, then decelerates, changes the direction of flow, and converts kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, and the gas flow changes into radial direction when passing through the impeller, thus entering the diffuser. In the multi-stage centrifugal fan, a reflux device is used to make the air flow into the next impeller, and a higher pressure occurs, so that the crushed material is sent to the feeder through the fan. The advantages of using this kind of centrifugal fan are obvious cooling effect, short ventilation time, and of course, there are also disadvantages, such as high unit energy consumption, poor ventilation and easy condensation.
