Description

Technical Field

[0002] Cone crusher is a crushing machine used for raw material crushing. Due to its large crushing ratio, high efficiency, low energy consumption and uniform particle size of the crushed product, it is widely used in raw material crushing in various fields such as mining, smelting, building materials, roads, railways, water conservancy and chemical industry. The feed inlet of the cone crusher is usually equipped with an end cover to prevent dust from flying around when the cone crusher crushes the material.

[0003] At present, most end covers have a tight sealing effect. When the cone crusher is working, the internal friction and collision are very serious, which will generate a relatively high temperature. When the temperature is too high, it may cause a fire inside the crusher. Due to the sealing of the end cover, it will be impossible to cool down the interior in time to extinguish the fire, which will cause the cone crusher to burn, thereby causing economic losses.
