In the 1980s, the rock crusher used the squeezing and bending action of the two jaw plates to crush materials of various hardness; if the movable jaw only makes a simple arc swing when working , It is called a simple swing jaw crusher in the
Mining crushers are mainly used for crushing large ore in mining technology. The process is crushed or broken, generally refers to the raw ore after mountain blasting, which is processed into a finished product size that meets the needs. With the development of mining rock crushers, the overall mining technology has been improved to a certain extent, and rock crushers are listed as core equipment in large-scale mining processing. According to the size of the feed and the size of the output, the crusher is used in the fields of coarse crushing, medium crushing and fine crushing of ore. The development of stone crushers is based on the continuous improvement of the application of stone crushers, and the product performance is also continuously improved to meet the needs to a greater extent.
In the 1980s, the rock crusher used the squeezing and bending action of the two jaw plates to crush materials of various hardness; if the movable jaw only makes a simple arc swing when working , It is called a simple swing jaw crusher in the industry; if it is moved up and down while working in a circular arc, it is called a complex swing jaw crusher. Jaw crushers are widely used in many sectors such as mining, smelting, building materials, highways, railways, water conservancy and chemical industries, jaw crushers crush various materials with compressive strength not exceeding 320 MPa. Due to the development of requirements, in order to avoid affecting production due to replacement of broken parts, hydraulic devices can also be used to achieve insurance and adjustment. Some jaw crushers also directly use hydraulic transmission to drive the movable jaw plate to complete the material crushing action. These two types of jaw crushers with hydraulic transmission devices are often collectively referred to as hydraulic jaw crushers.
