Why Does the Shot Blasting Machine Ignite Spontaneously?

　　The shot blasting machine is a kind of processing equipment used to remove rust on the surface of products. If it is high temperature, in order to avoid spontaneous combustion, the operator has to understand the cause of spontaneous combustion of the shot blasting machine to avoid the problem.

　　First of all, the shot blasting machine generates a lot of dust during the production process. To prevent it from polluting the air and causing harm to the human body, a corresponding filter cartridge dust collector will be equipped.

　　The dust produced by the shot blasting machine is generally iron powder, iron oxide or dust, and its ignition point is relatively low. Under the action of the airflow of the fan, the combustion speed is very fast.The filter material of the cartridge type dust collector is generally paper or polyester fiber, both of which are also flammable.

　　Therefore, if the shot blasting machine is processing aluminum parts, the metal powder inside may cause spontaneous combustion of the shot blasting machine if it is not processed in time.

　　In the working place of the shot blasting machine, the current is unstable. In daily operations, most of the internal mechanical energy of the shot blasting machine is converted into heat energy. During production operation, the temperature of the system will rise gradually. As long as the temperature of the internally processed steel sheet is controlled within 80°C, spontaneous combustion will not occur.

　　However, in many working places of shot blasting machines, the current is unstable. Once the overload occurs, if it is not handled in time, it will lead to abnormally high temperature, which may cause self-combustion hazards.
