What about the broken shaft of the cone crusher? How to solve it?

图片
The cone crusher is a crushing device commonly used in production. Spindle breaks are a common type of failure during production runs. Frequent breaks in the spindle not only affect normal production, but also aggravate routine maintenance and overhaul work. For this fault, this paper analyzes the cause of the fault and finds a solution. A detailed analysis of the causes of the main shaft fracture and the solutions are as follows. First, the reason for the broken shaft (1) The strength of the main shaft is weak: the static fit between the main shaft and the broken vertebral body causes stress concentration on the main shaft section, which significantly reduces the fatigue strength of the main shaft material. The main shaft gradually cracks during the crushing process of the crusher. The bending stress at the stress concentration of the spindle is broken beyond the strength of the material. (2) Overload operation: Due to insufficient spring pressure, the upper support sleeve of the cr...

Application of mobile crushing station in open pit mining industry

图片
Most of the users of open pit mines are power plants, and the coal supply requirements for power plants are less than 200 mm. Most small and medium-sized open-pit coal mines do not have Portable Crusher Plant . The particle size of coal does not meet the requirements, which directly affects the economic benefits of coal mines. The establishment of a fixed crushing station not only has a one-time investment, but also increases the secondary reversal link, which increases production costs. It also affects the economic benefits of coal mines. Open-pit coal mines have top-down rock layers, including cemented gravel layers and Jurassic strata, medium sand holes and fine sandstones. The rock mass is dense, hard, and uniform in structure. Moreover, under the condition of crushing, different types of rock and soil have different vibration responses to the fracture. Since the coal-bearing stratum is a homogeneous rock mass, the ability to accept the propagation of detonation waves is related t...
