jan 04, 2019 impact crushers. An impact crusher uses mass and velocity to break down feed material. first, the feed material is reduced as it enters the crusher with the rotating blow bars or hammers in the rotor. the secondary breakage occurs as the material is accelerated into the stationary aprons or breaker plates.
the impact crusher is mainly composed of a rotor, a hammer, a first counterattack plate, a second counterattack plate, a tie rod and a body that suspend the counterattack plate. the hammer and rotor are rigidly connected. rotor. the rotor structure of impact crusher
this invention relates to rotary impact crusher rotors used to communicate rock and to such rotors which are of substantially triangular shape having outlets at the apices of the triangle. this results in a rotor having reduced wearing surfaces and also avoids destruction or explosion of the rotor in the event of an excessive build up of rock in the crusher chamber.
nov 13, 2018 In order to meet the needs of crushing large size stone and ore, the high-speed rotating impact crusher rotor with a plate hammer has to be of sufficient weight and smooth operation. No matter when replacing new plate hammer or repairing old ones, the balance of the rotor should be paid attention, otherwise it will affect the normal operation of the equipment.
the high-speed rotating rotor with plate hammer is the main working part of the impact crusher. In order to meet the needs of crushing large pieces of ore, the rotor needs to have enough weight and run smoothly.no matter replace the new plate hammer or assemble the old plate hammer, pay attention to the balance of the rotor, otherwise it will affect the normal operation of the equipment.
Jan 14 2020 · impact crusher works with impact force of rotor. impact crusher with deep rotor can make good use of the impacting energy of its rotor, so that it often used for the coarse crushing, medium crushing and fine crushing of crisp materials with below medium hardness such as calcium carbide, limestone, dolomite, coal, vulcanization iron ore, quartz, gypsum and chemical raw materials
the impact crusher is widely used and of high production efficiency and good safety performance. the finished product is of cube shape and the tension force and crack is avoided. compared with hammer crusher, the impact crusher is able to fully utilize the high-speed impact energy of entire rotor.
