[0002] The pendulum mill is widely used in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower industries to crush and process mineral materials. It is mainly composed of main machine, analyzer, powder collector, fan, pipeline and other components. The qualified particle size materials in the silo are continuously fed into the main machine grinding room for grinding through the feeder. The ground powder is taken away by the air flow blown into the mill by the centrifugal fan, and is classified by the analyzer. The powder that meets the fineness enters the cyclone powder collector through the pipeline with the air flow for separation and collection. The finished powder is discharged through the discharge valve, and the separated air flow is sucked into the centrifugal fan by the return air duct at the upper end of the cyclone powder collector. The unqualified powder is separated by the analyzer and thrown to the cylinder wall. After falling along the cylinder wall, it returns to the mill for grinding. The main machine of the pendulum mill is a transmission device. Its mechanical transmission has gears, bearings and other parts, and these parts are installed in the gear box. The original pendulum mill gear box structure is complex and the assembly cost is high. Utility Model Content
