Cone Crusher Feed plate

This paper elaborates on the cone crusher feed plate, a key component in the material feeding system located at the top of the crusher's feed inlet. It functions to guide material flow, prevent backspray, reduce impact stress, and control feed rate. The component's composition and structure are detailed, including the plate body, mounting flange or bolt holes, impact-resistant liner, baffle plates (in some designs), reinforcing ribs, and chute or inclined surface, along with their structural features. For high-chromium cast iron variants, the casting process is described, covering material selection, pattern making, molding, melting, pouring, cooling and shakeout, heat treatment, and inspection. For steel plate variants, the machining and manufacturing process is outlined, including plate cutting, bending and forming, welding of reinforcements, surface treatment, and liner installation. Additionally, quality control measures are specified, such as material validation, dimensional accuracy checks, weld quality inspection, impact and wear testing, assembly and function testing, and final inspection. These processes ensure the feed plate has high impact resistance, wear resistance, and dimensional accuracy, guaranteeing reliable material feeding and protection for the cone crusher in heavy-duty operations.
