Preparation and commissioning of ball mill equipment

The ball mill equipment should be mounted on a solid concrete foundation. For the basic design and construction of the ball mill, please refer to the ball mill assembly drawing and foundation drawing. In order to ensure that the use of the ball mill parts of the location of the accuracy of the changes do not occur, the basis of the ball mill should be monolithic structure.

Concrete base compressive strength of 75% or more can be installed in the above ball mill. Before the installation of the quality of the foundation should be tested, the requirements of the concrete does not affect the strength of the defect, the number and location of holes reserved for the requirements, the reservation hole no debris and water, no oil. When using the "ground method" for installation work, on the basis of the surface should be embedded in the "center standard plate." Before the installation, draw all the center line and make a striking mark on the "center plate" as the center line of the installation.
1. Before the lifting of the ball mill parts should be a comprehensive acceptance, found that the problem in a timely manner.
2. The main bearing part of the specific requirements see the main bearing assembly diagram.
3. The cylinder part of the part of the assembly see the assembly map.
4. The transmission part of the drive part of the assembly diagram.
5. The overall relative position see assembly drawings.

Ready before the trial run
1. Cleaning the interior of the workshop, the construction of all the equipment to withdraw.
2. The ball mill equipment itself inspection cleaning:
(1) Whether there are items in the ball mill and debris;
(2) The ball mill into and out of the material within the Zizi and dust inside the debris;
(3) Ball mill bearings and mill outer cylinder cleaning;
(4) Clean coupling parts, ball mill bearings, reducer, motor surface;
(5) Inside the motor with compressed air blowing, and check the motor inside the debris.
3. Oil pipeline flushing, generally after the filter with 40 # oil plus 20% of the anti-rust agent rinse.
4. One by one by item check the ball mill anchor bolts, liner bolts tightening degree.
5.In the ball mill before the test run, the first high-pressure oil pump operation, the use of high-pressure oil film will hold up the ball mill float, reduce the ball mill torque, and then the ball mill and lubrication part of the oil filling.
6. Check the cooling water pipe is blocked, the ball mill before the test run, first cooling the water pipe joints to open the flushing pipe until the cooling water so far.

Commissioning requirements
In accordance with the ball mill motor, motor reducer, reducer ball mill to test run. China's cement machinery and equipment installation and acceptance of temporary technical regulations "Construction Rules 7-62" provides that the motor running air 4 hours, with a reducer running 8 hours, with a ball mill running 24 hours. Ball mill spindle and transmission pad temperature does not exceed 55 ℃, reducer rolling bearing temperature does not exceed 70 ℃, that is qualified. Now there is no clear provisions abroad, the ball mill running time, the general operation of two or three hours later, temperature and vibration remain in the specified range, is qualified.
