Description

Technical Field

[0001] This utility model relates to the field of mechanical crushing technology, specifically to an impact crushing device. Background Technology

[0002] White corundum micro powder is a high-purity corundum crystal produced by high-temperature melting and recrystallization of high-quality alumina powder in an electric arc furnace. The production process begins with bauxite as the raw material, followed by multiple steps including electric arc furnace smelting, crushing, and grading. The bauxite and bauxite used as raw materials are sedimentary rocks rich in aluminum minerals, and they need to be crushed into small pieces before being fed into the furnace. Currently, this process is generally accomplished using an ore crusher.

[0003] Ore crushers are industrial equipment used in mining, metallurgy, and building materials industries for material crushing. They mainly consist of a casing, rotor, hammers, and liners. The casing uses a modular bolted connection structure with internal liners. The rotor crushes materials through the interaction of hammers or impact plates. The main shaft is equipped with a flywheel to balance kinetic energy. The liners and impact plates, which are in direct contact with the ore, need to have a certain strength and are often made of alloy casting. In addition to the strength of the materials used for the liners and impact plates themselves, the mechanical strength of their mounting structure is also crucial, directly affecting the crushing effect and the durability of the equipment. In existing technologies, the conventional mounting structures for liners and impact plates still need improvement in terms of stability, while some integrated mounting structures are inconvenient for replacing liners and impact plates.
