Heavy-duty Apron Feeder

According to the design drawings, high-strength steel plates, alloy steel forgings (chain sprocket), cast steel parts (tank chain&roller), etc. shall be selected to ensure that the mechanical properties of the materials comply with the load-bearing requirements of apron feeder. Then, plasma and laser cutting machines are used to cut and process components such as the apron feeder support frame.

The outer circle of the apron feeder chain sprocket is processed on a heavy-duty horizontal lathe, the center hole of the chain sprocket is machined on a digital display floor-type boring and milling machine, and the bolt holes are processed using a CNC drilling machine. The apron feeder tank chains and rollers are precision cast, and the five-axis machining center is used to finish milling the working surface of the feeder support frame.

The apron feeder rack assembly welding uses CO₂ gas shielded welding for the root pass, combined with post-weld vibration stress relief treatment to eliminate residual stresses. The apron pan support welding employs low-hydrogen electrodes for fillet welding. The complete machine assembly involves positioning the apron feeder base frame, installing the rollers and chains, mounting chain sprockets and the drive system, and arranging the protective covers and lubrication system.

After going through the processes of material cutting, machining, welding, heat treatment, assembly, product testing, and painting, the final apron feeder was successfully manufactured. Zhenyuan Apron Feeder is widely used in various industries such as ores, construction aggregates, non-ferrous metals, coal, and others.
