2.1 Spindle: The spindle is supporting the rotor hammer crusher of the most major part, the rotor, the weight of the hammer, the impact of all its bear gravel crushing machine, so the spindle of material is required to have a high toughness and strength, the spindle Material made of high quality steel, machined by ultrasonic testing quenching and tempering treatment. 2.2 Hammer plate hammer crusher hammer plate is used to hang the hammer jaw crushing machine, hammer crusher in operation, the hammer plate ore inevitably be subject to impact and friction, so the hammer Order requires its It has some wear, hammer and hammer hole plate steel with high Meng carburizing heat treatment to improve the wear resistance. Hammer Crusher: Hammer crusher is directly 600-1800 mm maximum particle size of the material crushed to a period of 25 or 25 mm below the crusher crusher. Hammer crusher is suitable for cement, chemicals, power, metallurgy and other industrial sectors crushing medium hardness material, such as limestone, slag, coke, coal and other materials in the debris and crushing operations.
