Importance of jaw plate for jaw breaker

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.
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.
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. portable mining equipment: http://www.hx-crusher.com/n256.html
When the motor drive shaft rotation by pulley eccentric, connecting rods are up and down movement to lead the thrust campaign to make plate, before and after two thrust board by the formation of the Angle of the change to promote dynamic jaw movement. That can move around the jaw plate hanging a rotating shaft by swinging broken ore. When moving the jaw forward swing, the horizontal rod through the spring to balance the jaw and thrust plate produced by the inertia force, so that moving the jaw and thrust plate closely, not separation.
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.
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.As a professional and the best mining machinery manufacturer in China, Hongxing Machinery is always ready to provide the superior screw washing machine, feeder manufacturer, and these machines have the most competitive price and the most reliable quality so that they are the top choices for the high performance crushing equipment.
