Adjustment Method Jaw Crusher Discharge Mouth
When the task jaw grinding machine, the motor drive shaft through the pulley fair, so that the movable jaw periodically close to the fixed jaw broken, and thus the materials are squeezing, rubbing, grinding, such as multiple grinding the material into small, gradual landing, until discharged from the discharge port. Jaw mill discharge port (mine discharge port) is capable of conditioning based on user needs to have passed the product material size.
First, let’s be clear, jaw thrust plate mill, also known as brackets, in addition to transfer energy to make the movable jaw plate to swing back and forth to do, but also has the role of Ping An Insurance, changing its length conditioning also can play the role of the port of discharge.
When the jaw mill can not grind material into the cavity, the cover of the important parts and equipment from damage and take the thrust plate as a grinder of insurance components. After the thrust plate with cast iron cast the whole individual, in which the Ministry to open a slot or several holes to drop its cross-section strength; also cast two, and then link up with screws to form a combination of thrust plate.
When non-abrasive material into the grinding chamber, equipment overload, great grinding force to lead the thrust plate thrust plate thrust plate fracture or a combination of screws cut, electromechanical stagnation tasks, play a role as the insurance has been worn tooth plate, mine row by mutations in a large population, the product has been thicker, in order to pass the product size, the need to adjust the port of discharge current size.
Jaw crusher discharge opening adjustment method
Shim adjustments: After the posterior wall of the thrust plate mount and rack inspection, into a set of equal thickness gasket. By increasing or reducing the number of spacer layers, so that the crusher discharge mouth to decrease or increase.
Wedge adjustment: With the thrust plate holder and rear rack rear wall between the relative movement of the two wedge adjustment to achieve the crusher mouth. Go nuts on the bolts, the adjustment wedge along the back wall of the rack do move up or down, driving wedges before moving forward or backward, thus promoting the movable jaw thrust plate or to reach the port of discharge adjustment purposes.
Hydraulic adjustment: In recent years there to promote the installation of hydraulic cylinders to adjust the port of discharge at this location. Safety device, which is when the jaw crusher crushing chamber into the non-broken objects, in order to effectively prevent a security measure to machine parts are not damaged, and the use of. The most common is the use of a back pressure of the crusher plate safety device. Jaw crusher with hydraulic safety device, both reliable and secure, and easy-to-discharge failure.
Support device: Bearing part of a jaw crusher, large and medium-sized crushers are generally used cast babbitt bearings that can withstand greater impact loads, and more wear-resistant, but low to efficiency, the need for Forced lubrication. With the improvement of the rolling bearing manufacturing technology, the future of large jaw crusher is also bound by rolling.
