The fog cannon machine is composed of a wind tube assembly, a pitch adjustment device, a horizontal rotation assembly, an electrical control system, a base and a high-pressure spray water system. The base is composed of a control box and a base plate. The control box integrates 90% of the necessary equipment of the fog cannon, such as the electrical control components, water pump and motor. It can be fixed on the tower frame to increase its height and expand the dust removal range.
