Jaw crusher has simple structure, reliable operation and convenient maintenance. It is generally used for rough and medium crushing of hard and medium hard rock. The jaw crusher has a large crushing ratio, high efficiency and uniform particle size. It is mostly used for medium hardness rock. Broken Medium Fine Rock. It is mainly used for medium-sized crushing of various ores and large materials, and can crush materials with compressive strength not greater than 320Mpa, divided into two types: coarse crushing and fine crushing. This series of jaw crushing equipment, with a feed size of 125mm ~ 750mm, is the first choice for primary crushing and coarse crushing. Jaw crusher is widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries.


Operating principle: The motor drives the belt and the pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, so that the movable jaw plate is approached to the fixed jaw plate and the material is pressed at the same time. Crushing or chopping to achieve the purpose of crushing; when the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the tie rod and the spring. At this time, the crushed material passes from the crushing cavity. Lower mouth drain. With the continuous rotation of the motor, the motorized jaw is crushed for periodic movement to crush and discharge materials, and achieve mass production.
