Improved roller type high-frequency vibration crusher

Abstract

The invention discloses an improved roller type high-frequency vibration crusher comprising a machine body, a crushing roller, a vibration crushing device, a power transmission device, a crushing cavity, a feeding device and a material discharging device, wherein the crushing roller, the vibration crushing device, the power transmission device, the crushing cavity, the feeding device and the material discharging device are arranged on the machine body; the vibration crushing device comprises a vibration arm and the vibration arm is provided with a vibration excitation device; the power transmission device comprises a power speed-reducing device and a chain wheel and chain device; the crushing roller comprises an upper fixed roller, a lower fixed roller and a vibration roller, and comprises a roller base body; the roller base body is provided with a metal body which is different from the roller base body in hardness; and the crushing cavity is matched with a rotary shaft of the vibration roller through a movable magnetic sealing device. According to the improved roller type high-frequency vibration crusher, the disadvantages in the prior art can be well overcome, and the aims of good crushing effect, high efficiency, stability and reliability of operation, large-range energy conservation and consumption reduction, reasonable structure, small occupied area, and dustproof performance and environmental friendliness.

Description

technical field [0001] The invention belongs to crushing equipment, in particular to an improved roller-type high-frequency vibration crusher. Background technique [0002] Roller crusher is widely used as medium and fine crushing equipment in non-ferrous metal ore and non-metallic ore processing, building materials and other industries due to its simple structure, light weight, reliable operation, low price, uniform product size, and less over-crushing phenomenon. However, due to its low production efficiency, high power consumption, and the material is easy to slip when it is crushed on the roller surface, it will cause fast wear, low efficiency, uneven particle size before and after crushing, and large dust pollution. It needs continuous improvement. Chinese patent ZL200920004093.X discloses a high-frequency vibration crusher, which improves the traditional roller crusher and applies the vibration crushing technology to the three-roll crusher, which better solves the prob...

[0002] Roller crusher is widely used as medium and fine crushing equipment in non-ferrous metal ore and non-metallic ore processing, building materials and other industries due to its simple structure, light weight, reliable operation, low price, uniform product size, and less over-crushing phenomenon. However, due to its low production efficiency, large power consumption, and the material is easy to slip when it is crushed on the roller surface, it will cause fast wear, low efficiency, uneven particle size before and after the crushing, and large dust pollution. It needs continuous improvement.

Chinese patent ZL200920004093.X discloses a high-frequency vibration crusher, which improves the traditional roller crusher and applies the vibration crushing technology to the three-roll crusher, which better solves the problem of traditional roller crusher production. Problems such as low efficiency, high power consumption, rapid and uneven wear of the roller surface, and impact on the crushing effect

However, in the actual use process, it is found that there are still some problems that need to be continuously improved in the high-frequency vibration crusher: such as complex transmission structure, high manufacturing cost, and large equipment footprint; the horizontal movement structure of the vibration crusher is unreasonable, and the roller It is difficult to move when adjusting the gap after the surface is worn; the vibration frequency and amplitude of the exciter cannot be adjusted, resulting in uncontrollable crushing force, low efficiency, and poor applicability to working conditions; no box seal leads to leakage of dry crushing dust and pollutes the environment , Wet water-added crushing conditions cannot be realized, etc.
