jaw crusher lubrication

jaw crusher lubrication

[1] always pay attention and timely manner lubricated friction surface was working to ensure the normal operation of the machine and extend its life. [2] jaw crusher used lubricating grease should be based on the location of use, the temperature conditions may be, under normal circumstances using calcium, sodium and calcium sodium based grease. [3] adding grease within the bearing for about 50% of volume of space, every 3 to 6 months to replace a. Oil change, application of clean gasoline or kerosene cleaning roller bearing raceway. [4] Before starting jaw crusher, thrust plate and thrust plate between supports should be injected into the right amount of grease.

jaw crusher components & parts

jaw crusher components & parts

These are the parts and components that generate the crushing action and provide the energy needed to break the ore. Lets follow the chain of events within a crushing cycle to see how they all go together. The first component of the crusher is the drive motor. This will drive a reducer sheave that isattached to an eccentric shaft. On the other end of the shaft is the flywheel.

The purpose of the flywheel is to generate energy in the form of motion. Once the motor has the flywheel turning the momentum of the wheel will carry it through a crushing cycle. The motor then will only have to provide the energy necessary to propel the fly wheel.

That is where the energy comes from, the crushing action itself is generated by the eccentric shaft, and this shaft is called the pitman. This is simply a shaft with a portion of its length offset from the rest of the shaft. As the shaft is revolved that portion will travel in a greater arc. By attaching a bearing system called the pitman bearing and cap to it is possible to generate a motion whose direction is primarily up and down.

There is an arm extending from the pitman that the toggle plates sit in. The toggle plates are set at an angle to the arm and the swing jaw. As the pitman is revolved the arm is pulled up. This causes the toggle plates to come to the horizontal position. The movement of the toggle plate forces the swing jaw to be pushed outwards towards the stationary jaw thus crushing the ore.

Depending upon the make of Jaw crusher the Toggle plates may provide another very important function. With some designs the toggle plates are made up of two steel plates that are bolted together with what is known as SHEAR BOLTS. These are bolts that have a known shear strength. If something that the crusher cannot crush accidentally gets into the crushing chamber these bolts will shear off when the Jaw hits the unbreakable object. This will prevent damage to the rest of the crusher.

Unlike the gyratory crusher the main lubrication used on Jaw crushers is grease instead of oil. In using grease there may be several different ways that it will be fed to the necessary lubrication points. It could be manually with a grease gun. Or possibly grease pots or metering pump will be the system used. Whichever it is, the bearings will be a critical portion of the operators circuit checks.

how to solve the high temperature of jaw crusher bearing?

how to solve the high temperature of jaw crusher bearing?

Jaw crusher bearing-Causes and solutions of excessive temperature Bearing is the most important part of the jaw crusher. It is easy to cause failure and damage the bearing under high temperature. The following is the reason and solution of the high temperature of the jaw crusher bearing explained by Red Star Heavy Industry. 1. The crusher bearing is worn or the cage is damaged, etc.: Check the wearing parts of the mechanical equipment in time and replace the worn bearings.

2. The axial movement of the adapter bushing: remove the bearing cover on the frame, lock the adapter bushing and remove the flywheel or groove wheel, and replace with a new adapter bushing. 3. The position of the counterweight of the flywheel of the crusher is out of alignment, and the frame jumps: the position of the counterweight of the flywheel is adjusted to ensure that the position is not offset. 4. Crusher bearing oil hole is clogged, oil can not be added: clean oil hole, oil groove blockage. 5. The crusher bearing has oil cut-off or too much oil injection: When the user is operating the equipment, please read the instructions carefully, and add oil on time according to the instructions.

6. Non-crusher bearing heating: friction heat generated by the movable jaw seal sleeve and the end cover or the double-embedded cover of the housing bearing seat rotates together with the main shaft to generate friction and heat. In this case, the end cover and sealing sleeve of the jaw crusher should be replaced, or the upper bearing cover of the hot end of the frame bearing seat should be loosened, and the fuse and the embedded cover should be pressed into the groove of the frame bearing seat, and then the upper bearing should be fixed. Cover to eliminate the rotation of the embedded cover.
