Balanced Rotors in all impact crushers should be standard from the original equipment manufacture (OEM). The balance of the rotor is extremely important and will ensure the rest of the crushing plant structure has a long and event free life. It will also ensure the bearings of the rotor last for the design service life.

1. Impact crusher structure. 1.1 Impact crushers can be divided into two types according to the number of rotors: single-rotor and double-rotor impact crushers. 1.2 The structure of the single rotor impact crusher (Figure 1) is relatively simple and consists mainly of the rotor 5 (strike plate 4), the impact plate 7 and the machine body.
3) Maintenance point of Impact crusher 's rotor ① Do regularly inspect the abrasion situation of the flat hammers, impact plate, guard plate and rotor, and change or repair the abraded parts. Tighten the connecting screws to avoid dropping. ② Pay attention to the raw material to see whether there are metal things.
The working conditions of impact crusher are severe, which will aggravate the wear of rotor bearing. Once the rotor fails, the cost of repair and replacement is very high, and replacement is very difficult. So, it is very important to take effective measures to increase the service life of rotor bearings in impact crusher.
In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material is crushed as it hits of the outer body at high speed and due to rocks colliding against each other.
Rotor, plate hammer and impact plate are the main body of impact crusher, which affect the impact crusher's overall performance.. Rotor: Rotor is the key working parts of impact crusher, which must have enough weight to crush lump ore. Therefore, the rotor of large-scale impact crusher generally is integral cast steel structure.
A rotor of an impact crusher may include a crushing roll body that can be rotated about a center line of the crushing roll body. The crushing roll body may include at least one radial recess. The rotor may further include at least one blow bar positioned in the recess of the crushing roll body. Still further, the rotor may include at least one chock positioned in the recess between the …

crusher,Jaw crusher and Impact crusher. Our objective is to design various components of an Impact crusher like drive mechanism, shaft, rotor,hammers, casing,feed and discharge mechanism which will be useful in minimizing weight, cost and maximizing the capacity. Impact crushers: they involve the use of impact rather than pressure to crush
⑥ After overhaul of the impact crusher or repair of the rotor, do ensure that the rotor can rotate flexible and evenly. The impact plate shall be exchanged at the same time; otherwise, the unbalanced rotor will cause the vibration of the impact crusher. Our company is a professional and reliable impact crusher manufacturer. More information ...
Hammer (impact) crusher: The feed is fragmented by kinetic energy introduced by a rotating mass (the rotor) which projects the material against a fixed surface causing it to shatter causing further particle size reduction. This crusher produces more rounded shape. •
The impact crusher (typically PE series) 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.
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.
Vertical shaft impact crushers. Vertical shaft impact crushers take the full advantage of so-called rock-on-rock crushing process. In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material ...
Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller.
the invention also provides a rotor for a rotary impact crusher in which there is included in the rotor a feed ring releasably engaged in the rotor on a supporting flange with the feed ring...
A sand and aggregate company applies impact crusher as the second crushing equipment. The impact crusher has been running normally for 4 years. After routine shutdown inspection, it was found that there was a crack in the rotor of the impact crusher. Emergency measures were taken to deal with the problem, so that the production could proceed ...
