Description

Crushing cavity structure

Technical Field

The invention relates to the technical field of crushers, in particular to a crushing cavity structure.

Background

The vertical shaft impact crusher is also called a sand making machine, and is usually arranged in a sand making production line and used for fine crushing and shaping sand and stone aggregates. The crushing step is carried out in a crushing cavity of the sand making machine, and the rotor throws out the material at a high speed to collide with the impact block or the impact lining plate for crushing. According to the working form, the crushing type can be divided into a stone-breaking type and a stone-breaking type.

The specific form of the stone beating is that high-speed materials thrown out by a rotor collide with waterfall materials falling down around a feed hopper or a material lining accumulated in a crushing cavity for multiple times of collision and grinding. Finally, the steel falls into the bottom base. The 'stone iron beating', namely the collision of high-speed materials in the rotor and a metal impact block in the crushing cavity, achieves the purpose of crushing.

The "stone breaking" is characterized by that it is applicable to breaking medium-hard and above-medium-hard material with large corrosivity, such as basalt, etc.. In the crushing process, the materials ejected by the rotor impact the impact lining plate without directly contacting with metal elements of equipment, so that the iron loss is reduced, and the maintenance time is shortened. The finished product has good particle shape but slightly more powder content under the working condition of stone breaking. The 'stone breaking iron' is suitable for breaking materials with low abrasiveness below medium hardness, such as limestone and the like, and has the advantages of high breaking efficiency, high abrasion rate of a counterattack block and slightly poor grain shape of a finished product under the working condition of the 'stone breaking iron'. The two kinds of broken forms of "stone is beaten stone" and "stone is beaten iron" quick switching can't be realized to prior art, consequently in order to satisfy broken demand, the enterprise often needs the breaker of two kinds of broken forms of purchase, and purchasing cost is high, and the utilization ratio of breaker is lower.

In conclusion, a crushing cavity structure capable of realizing switching of two crushing modes of stone breaking and iron breaking is urgently needed to solve the problems in the prior art.
