Ball mill is the important equipment in mineral ore grinding or mineral powder making and beneficiation, so ball mill installation and maintenance are become the important thing, following are common knowledge about ball mill machines’ installation.

i. large ball mill must be installed in the already dry solid reinforced concrete foundation.

ii. basis of allowed significantly tilted and sinking, if a little Shen should be balanced and level, otherwise it can not be installed.

iii. class mill base should be of sufficient height and low plane, in order to supply the replacement liner and the use of the grinding media.

Preparatory work before the installation of the large ball mill

i. rust oil, so parts and components processing work surface protection, and transport Falling on dust and dirt must be removed prior to the installation of the large ball mill.

ii. Check a the processing work surface and thread, and should be in the shipping and handling process, elimination of the defect.

iii. assembled parts should be carefully checked, found in some parts of the transportation and custody damaged or lost, you must fix the defective parts, missing pieces complement.

iv. large ball mill installation part of the contact with the machined surface should be lubricated, fixed surface with the dry oil activities surface with thin oil.

v. before installing slot based on pit should be clean and clear, and should be done last pouring the cement surface must not have grease.

vi. installation should protect the friction surface, not to scrub with cotton or dirty oil, dirt parts machined surface is easy to place special guard and clean canvas cover.

Ball mill rotating portion part installation

i. in the case of lifting equipment, rotating part in a the fastening dedicated gallows installation (box piled the gallows Department sleepers or other hard wood) should draw jack rotation gently rotating part no impact on the bearing bush.

ii. should be cleared of all connections and the mating surface on the dirt.

iii. allowed lifting the entire rotating part with the rings on the end cap.

iv. the cylinder flange expected out cover flange contact surfaces are not allowed to add any gasket should be coated with a layer of red lead, but before assembly.

v. expected out of a ring gap in the cylinder liner end liner applications cement mortar choked. Its composition of cement: sand = 1:2-3

For different types of ball mill, there have different requirement, such as dry ball mill and wet ball mill. So customer should choose suitable installation method.

i. for dry ball mill, the hopper and the barrel should be consistent with the rotation axis, its level application to adjust the shim method to reach, slowly rotating cylinder to the hopper and the barrel free twist and vibrate phenomenon, that is suitable for description of the location of the installation, and then tighten footscrews.

ii. for wet ball mill, feeding Ministry rotating part installed, firmly installed in the feed opening all spiral should maximize tighten feeder spoon head is not allowed to have any loosening.

Ball mill drive part installation

i. checking, the pinion centerline parallel, its unbalance shall not exceed the standard requirements.

ii. checking pinion backlash, its value should ensure that within the range of 0.4-1.2mm, the tooth surface contact application coloring inspection the contact length tooth length shall not be less than 50%, then angle a height of not less than 60% of the tooth height.

iii. the installation of the gear unit, should ensure that the two with the axis of the shaft in the same horizontal plane, the concentricity and inclination of the low-speed shaft with the gear shaft, each not exceed the technical requirements.

Regardless of the installation of large ball mill, or a medium-sized ball mill or small ball mill installation must be installed in the technical staff under the guidance of the ball mill manufacturers If you need more technical support, please feel free to contact with us Our engineer team will do our best service to give you complete ball mill support.
