Description

A primary ore crushing device

technical field

The utility model relates to a primary crushing device, in particular to a primary crushing device for ore, which belongs to the field of mining machinery.

Background technique

Stone crushers can be divided into medical stone crushers and mining stone crushers according to major categories. In principle, the mining crusher is suitable for crushing a large number of hard rocks in mines. Its typical granite output particle size is less than or equal to 40mm, which accounts for 90%. The crushing ratio is large, and the crushed material is in the form of cubic particles. Mining stone crushing machinery refers to the crushing machinery in which the content of the particle size greater than 3 mm in the discharge accounts for more than 50% of the total discharge volume. Mining crushers mainly crush all kinds of stone materials. , is divided into many models. Crusher is widely used in many departments such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries. Commonly used crushing machines include jaw crusher, impact crusher, vertical impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher, cone crusher Crusher, double-stage crusher, gyratory crusher, mobile crusher, etc.

At present, it is known in the quarry mining industry that the moving plates on the crusher are all processed from a single steel. Since the moving plate is processed from a single steel material, it has low hardness and is easy to wear. If it is not used for a long time, it needs to be scrapped and replaced.
