We all know that there are two types of crushers, jaw crusher and hammer crusher, so today I will analyze the difference between these two types of crushers through the working principle and performance characteristics of the two, let’s take a look. Bar.
The working principle of the jaw crusher: The three-phase asynchronous motor of the jaw crusher drives the eccentric shaft of the rotor to rotate at a specified speed through the V belt, and the movable jaw head suspended on the eccentric shaft drives the movable jaw plate to move relative to the fixed plate along a certain trajectory Squeeze and shear to realize the crushing of materials. The trajectory smaller than the discharge port is conducive to the crushing of large materials. When foreign non-breakable materials enter the crushing cavity and the load suddenly increases, the toggle plate can protect other parts from damage through its own crushing.
Jaw crusher is one of the most popular stone crushing equipment in the world. It is mainly used for coarse crushing and medium crushing of various materials with compressive strength not exceeding 320MPa. It has a large crushing rate, high output, uniform product size, and structure. It has the advantages of simplicity, reliable work, simple maintenance, low operating cost and wide application range. Crushers have been widely used in mining, smelting, building materials, highways, railways, water conservancy and other industries.
The working principle of the hammer crusher: When the material enters the crushing chamber, it is impacted by the high-speed rotating hammer head, and the material is crushed by the impact of the high-speed impact plate and the frictional impact between the high-speed flying material. The materials that meet the particle size requirements are discharged from the designated sieve. After the initial crushing, the materials that do not meet the requirements will be crushed again by the hammer along with the new materials. When super-large materials enter the crushing chamber, the pre-installed load-bearing rod is blocked at the upper part of the crushing chamber, and then is broken into small and medium-sized materials and then falls into the lower crushing chamber, thereby avoiding the sudden increase in load due to the entry of large materials The damage to other working parts at the time ensures that the crushing is more stable.
The hammer crusher achieves crushing through the collision between the high-speed rotating hammer head and the stone and the mutual collision between materials. It has the advantages of simple structure, high efficiency and high output. Hammer crushers are widely used in dry and wet crushing, medium and low hard materials crushing, mining, cement, coal, metallurgy, building materials, road construction, petrochemical industries and other industries.
