The high-efficiency centrifugal vertical shaft impact crusher is a new generation product introduced by our company, incorporating German technology and holding multiple independent patents. It combines three crushing modes into one and has become a new, highly efficient crusher at the core of the mechanism sand industry.
This equipment finds extensive applications in the crushing and shaping of both metallic and non-metallic ores, building materials, artificial sand production, and various metallurgical slag materials. It is suitable for brittle materials with Mohs’ hardness less than 9 but is not suitable for materials with high viscosity or those containing a significant amount of clay.


  • After optimized design, the deep-chamber rotor can make the capacity increased by 30%;

  • Surrounding plate can be inverted, to improve the material’s utilization and increase the lifespan by more than 48%;

  • Combined hammer design, only need to replace the wearing part, can reduce the operation cost by over 30%. And the use of vice hammer can prevent damage to the vertical plate after the main hammer worn;

  • The key components’ material adopt the wear-resistant and high temperature resistant materials of the important industries in the USA;

  • Rhombus shape impact plate is used to prevent the damage of vertical plate;

  • The selection of bearing is international brand from Japan, Sweden, America, etc;

  • The design of optimal launch mouth and smooth curve reduces flow resistance of the materials and increases the throughout capacity greatly;

  • Dual-use material distribution tray is easy to operate and can make two feeding way changes easily;

  • Special seal structure in lower part of main shaft guarantees no oil leak even without seal;

  • Japanese hydraulic opening cover device is originally imported. The cover is moved easily and replacement and inspection of inner part is easy;

  • The selection of high level protection of the motor with features of high efficiency, low noise, etc. The motor complies with (IEC) International Electrotechnical Commission standard, F class insulation, IP54/55 protection level.


Centrifugal vertical shaft impact crusher uses high-speed movement of materials with their own friction to crushing. Centrifugal vertical shaft impact crusher not only crushes, but also shapes the stone. According to the feeding pattern, there are two working forms: completely central feeding and central feeding with cascade feeding; according to the crushing resistance and corrosiveness of the materials, there are two working forms: crushing between materials and crushing between materials and liners. So totally there are four kinds of the working forms.

  1. Working principle for central feeding with cascade feeding and crushing between materials

The materials enter the machine from the feed hopper, and fall into the material tray through the material distribution plate, and be divided into two parts. One part of material enter the high speed rotated rotator through the center of the distribution tray and are accelerated quickly inside the impeller, and then are thrown out through flowing chute of the impeller at high speed, firstly are crushed by impact with another parts of the materials falling from the distribution tray, and then together they are impacted to the material lining of the crushing chamber,after that they are rebounded from the material lining up to the top of the crushing chamber, and then change the moving direction from upwards to downwards and formed continuous material screen. In this way, one piece of the material will be impacted, crushed, and grinded many times in the crushing chamber. The broken materials depart from the crushing chamber under the gravity action and fall into the lower-part shell and are discharged by the discharge hopper. Upper and lower impact protecting pieces are installed on the wall of the crushing chamber to protect the body shell from wearing. Its characteristic is that the materials are accelerated by the rotator, and half of the materials are thrown out by the energy got from the rotator and then crushed, impacted, grinded with the materials lining or the materials crushed by their own high speed rotated impact, which is called “crushing between materials”


  1. Central feeding with cascade feeding and crushing between materials and liners

Main working principle is the same as central feeding with cascade feeding and crushing between materials. The difference is when crushing between materials, impact protecting pieces are installed in the crushing chamber, and the materials are formed lining around it and the materials are impacted into the lining and then crushed, however when crushing between materials and liners, the lower impact protecting pieces are changed with the guard plates/liners, and the materials are directly impacted to the liners and crushed then.

  1. Completely central feeding and crushing between materials

Main working principle is the same as central feeding with cascade feeding and crushing between materials. The difference is when completely central feeding, the distribution cone will be adjusted, and the materials fall into the distribution tray directly from the feed inlet and then come into the throw wheel through the center of the distribution tray.

  1. Working principle of completely central feeding and crushing between materials and liners

Main principle is the same as the central feeding with cascade feeding and crushing between materials and liners; however the feeding way is completely central feeding.

Crushing between materials is suitable for the materials with medium and above hardness and high corrosiveness such as basalt, etc. During the processing, the materials thrown out from the rotator and impact with the material lining, while not impact with the metal components of equipment directly. It can reduce the wastage and accordingly can reduce the time for maintenance and serving. The shape of the final products during this process is good and with a little more powder.

Crushing between materials and liners are suitable for the materials with hardness below medium level and low corrosiveness such as limestone, etc. And during this processing, the ratio of crushing is high but the cost of worn guard plate/liners is high too, and the shape of final products is not as good as the above process.
