Jaw Crusher Components
While the jaw crusher is running, the true heart of the jaw crusher and its components is the brackets, the pitman and the sheaves.
These are the Jaw Crusher Components and components that produce the breaking action and provide the energy needed to crush the ore. Let’s look at the chain of events along a broken cycle and see how they fit together. The first part of the crusher is the drive motor. This will drive the reducer sheave connected to the eccentric shaft. At the other end of the shaft is a flywheel.
The purpose of the flywheel is to generate energy in the form of motion. Once the motor has a flywheel, the momentum of the wheel will cause it to pass through the crushing cycle. The electric motor will then only need to provide the energy needed to propel the flywheel.
This is where the energy comes from, and the crushing action itself is produced by the eccentric shaft, and the axis is called pitman. This is simply an axis that is part of its length offset from the rest of the axis. As the shaft rotates, the portion will travel in a greater arc. By connecting the bearing system, known as the connecting rod bearing and the cap, the main vertical movement can be generated.
There is an arm extending from the toggle plate at the toggle plate. The bracket is at an angle to the arm and the rotating jaw. When pitman rotates, the arm is pulled up. This causes the bracket to reach the horizontal position. The movement of the toggle plate forces the oscillating jaw to move outwardly toward the fixed jaw, thereby breaking the ore.
According to the manufacture of the jaw crusher, the switching plate can provide another very important function. In some designs, the toggle plate consists of two steel plates joined together by so-called “SHEAR BOLTS” bolts. These are bolts of known shear strength. If the crusher can not break things into the crushing chamber accidentally, when the jaw is not easy to break objects, these bolts will be cut. This will prevent damage to the rest of the crusher.
Unlike gyratory crushers, the primary lubricant used on jaw crushers is grease rather than oil. In the use of grease, there are several different ways to supply them to the necessary lubrication points. It can be manually operated with an oil gun. Or a fat can or metering pump may be used. Whatever it is, the bearings will be a key crusher part of the operator circuit inspection.
