Jaw plate is the most consumed, so we must take it in good quality when choosing jaw plate life is an important indicator of good or bad quality. Jaw crusher body of work is fixed jaw and movable jaw formed consisting of the working chamber, fixed jaw and movable jaw are under enormous crushing force and the friction material, easy to wear out, in order to protect the jaw, generally in the fixed jaw and movable jaw surface wear of the liner installation, also known as broken boards. Jaw plate surface is usually made of tooth, jaw plate angle of tooth peaks 90 ° ~ 120 °, its size has been broken by the nature of the materials and fragmentation may be.
Pitch depends on the product’s size, usually about equal to the discharge port to take the width, height and pitch of the teeth than desirable 1 / 2 to 1 / 3. Work, the lower jaw plate wear faster than the upper, jaw plates in the jaw crusher work, direct contact with the material, under enormous crushing force and the friction material, jaw plate life is directly related to the jaw crusher machine efficiency and production costs, therefore, to extend the jaw crusher jaw plate life is particularly important.
Jaw crusher crushing action extrusion method using music, motor-driven belt and pulley, the eccentric shaft to move up and down jaw movement, when the movable jaw rises between toggle plate and moving jaw angle becomes larger, thus promoting the movable jaw close to the fixed jaw plate, while the material is squeezed, rubbing, grinding, etc. broken in multiple ways; when the movable jaw down, the elbow angle between the plate and moving jaw smaller, movable jaw plate in the bar, under the action of the spring leave the fixed jaw plate, this time the material has been broken under the discharge port from the crushing chamber, with the mobile jaw crusher motor for continuous rotation of the crushing and periodic discharge, to achieve mass production.
When moving the jaw back, the spring can also play supportive role. Eccentric shaft crusher important parts, drive rod up and down movement because of its work under a lot of crushing force, generally of high quality alloy steel. Link to withstand the tension as a result, it is manufactured with cast steel, in order to reduce the quality of connecting rod, connecting rod made often of the lower section of the special shapes.
Large jaw crushing machine is mainly used a combination rod. Combination of link quality, small, save material, and has a simple device. Thrust plate, also known as brackets, is passed to the jaw movement of a bar, and use it as a device. Change the length, you can also adjust the size of discharge mouth. Generally with the whole cast iron, cast whole also cast two pieces of, then bolts or rivets joined up.
In the operation of movable jaw crusher, the jaw plate movement is the eccentric rod, and thrust with the board to achieve, it is by the flywheel, eccentric shaft, connecting rod, thrust plate and thrust board (known as cubits after board) composition. Two flywheels are mounted on both ends of the eccentric shaft. Eccentric shaft supported on bearings on the wall rack.
