Description

Technical Field

[0001] This utility model relates to the field of vibration machinery and equipment, and in particular to a high-efficiency impact plate for impact crushing. Background Technology

[0002] Vertical shaft impact crushers are widely used for medium and fine crushing of various hard and brittle materials such as rocks, abrasives, and refractory materials. Their working principle is as follows: large particles, after being accelerated by the impeller, collide with the impact plate, rebound back into the crushing chamber, and continue to collide with other particles. Under the action of gravity, the small particles, after several collisions and reshaping, are discharged through the discharge port, completing the crushing process. The main function of the impact plate is to withstand the impact of large particles thrown by the impeller, causing them to break, and then bounce the broken particles back into the crushing zone for further impact crushing, thereby obtaining the desired product particle size. The appearance of the impact plate has a significant impact on the production efficiency of the impact crusher. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a high-efficiency impact plate for impact crushers.

[0004] The technical solution adopted by this utility model is as follows: the high-efficiency impact plate for impact crushing includes a waist-shaped through hole, a mounting part, an impact ramp, and a bottom surface; the mounting part is located at the tail of the high-efficiency impact plate for impact crushing; the waist-shaped through hole is provided in the middle area of ​​the mounting part; the impact ramp is located at the front of the high-efficiency impact plate for impact crushing; the bottom surface is located at the bottom of the high-efficiency impact plate for impact crushing, and the bottom surface is horizontally arranged; the impact ramp forms an acute angle with the bottom surface.

[0005] The beneficial effects of this invention are: the high-speed particles from the impeller impact the inclined impact surface and rebound with an upward component velocity, which can prolong the residence time of the particles in the crushing chamber, increase the number of impacts of the particles, and thus improve the particle shaping efficiency.
