Description
Technical Field
The invention belongs to the field of crushers, and particularly relates to a high-efficiency split stone crushing device.
Background
The crusher is very important mechanical equipment in the industrial field, and is mainly used for crushing and grinding various materials; during crushing, the activity of the impact plate is a very important part, and the impact plate is usually located at the top or side of the crushing chamber, and its main roles include the following aspects:
protection equipment: when the large-sized materials enter the crusher, the impact piece can decompose the large-sized materials into small-sized materials through collision and crushing, so that the crusher is protected from being damaged by the large-sized materials;
and (3) adjusting the crushing effect: the crushing degree and the granularity of the materials can be controlled by adjusting the gap between the impact piece and the hammer head; when the gap is smaller, the impact force applied to the material is increased, and the crushing effect is finer; when the gap is larger, the impact force applied to the material is reduced, and the crushing effect is thicker;
promoting material flow: the existence of the impact piece can change the movement direction of the material, so that the material forms certain fluidity in the crushing chamber, and the crushing and the discharge of the material are facilitated.
Thus, the impact plate of the crusher is an important component in the crusher, which functions to crush the material and adjust the crushing effect; however, in actual use, the impact tab structure also has some drawbacks:
first), impact piece is easy to wear: impact sheets are often impacted and rubbed by materials in a crusher, so that the impact sheets are easy to wear; when the impact piece is worn to a certain extent, the gap between the impact piece and the hammer head is increased, so that the crushing effect of materials is affected;
second), impact piece is inhomogeneous to the crushing effect of material: due to the existence of the impact sheets, the materials can be impacted and crushed for multiple times in the crusher, but the impact sheets at different positions have uneven crushing effect on the materials; this can lead to different particle sizes of the materials, affecting production quality and yield;
third), the adjusting difficulty of the impact piece is larger: when the gap between the impact piece and the hammer head is adjusted, a worker with abundant experience is required to operate; if the gap is improperly adjusted, the crushing effect of the materials is unstable, and the energy consumption and the maintenance cost are increased; meanwhile, the adjustment of the impact piece is also required to be stopped, so that the production efficiency is affected;
fourth), the impact piece is easy to loosen and fall off: in long-term use, the impact piece is easy to loosen and fall off, which can influence the matching and crushing effect of the impact piece and the hammer; if the impact piece falls off seriously, even equipment damage and production accidents can be caused.
