Description

[0002] Hammer crusher is a kind of equipment that crushes materials by impact. It is divided into single-rotor and double-rotor types. It is a crusher that directly crushes materials with a maximum particle size of 600-1800 mm to 25 or less mm. Hammer crusher is suitable for medium and fine crushing of medium hardness materials such as limestone, slag, coke, coal and other materials in cement, chemical, electric power, metallurgy and other industrial sectors.

[0003] The built-in hammers of existing hammer crushers are generally designed as an integral whole and are connected to the mounting shaft on the rotor disk through the shaft hole at the tail. When the hammer is damaged after long-term use and needs to be replaced, the rotor disk must be disassembled and the mounting shaft must be removed to remove the hammer. At the same time, the damaged and worn parts of the hammer are generally those in contact with the materials. It is wasteful to replace all the hammers. At the same time, when the crusher is working, the crushed materials may clog the grate screen slits, especially when crushing sticky and wet materials, which is easy to clog the grate screen slits, which is easy to cause shutdown. When crushing sticky and wet materials, the grate bars are easy to clog and the production capacity is reduced.
