Crusher manufacturers explain the Zimbawe Stone Crushers working principle and performance characteristics of jaw crushers. After more than 100 years of practice and continuous improvement, the structure of jaw crusher has been perfected. It has the characteristics of simple structure, reliable work and convenient maintenance, so it is still widely used in production departments such as building materials, chemical industry and mineral processing. In the jaw crusher, the material is crushed between the existing jaw plates. The movable jaw plate periodically swings around the fixed mandrel to the fixed jaw plate. When the movable jaw plate is close to the fixed jaw plate, the material between the two jaw plates is crushed by the action of squeezing and breaking.
When the active jaw plate leaves the fixed jaw plate, the broken material is discharged through the discharge port under the action of gravity. There are two types of jaw crushers that are widely used: simple swinging jaw crushers-jaw crushers with crank and rocker mechanisms that move the jaws for complex swings. The former is mostly made into large and medium size, mostly used for coarse crushing operation, and the crushing ratio is f = 3-6; the latter is generally made into medium and small size, mainly suitable for medium and fine crushing operations, and the crushing ratio can reach 10. Complex swinging jaw crusher is developing in the direction of large-scale. In recent years, hydraulic technology has been applied to crushing equipment, and hydraulic jaw crushers have appeared. Which jaw crusher is better, we are more trustworthy.
