Design Principle determine the Ball Mill Work Process

According to the mill working principle, we do the following instructions about the important questions on the maintenance and overhaul aspects :
(1)
pay close attention to the main bearing's temperature, it should not exceed 60
℃.
(2) should always check the main bearing reducer, motor lubrication and
fuel supply adequacy these situations, pay attention to the supplementary
lubricants. Winter fuel or oil, should be pre-heating the oil to 200C or so,as
to the lubricants which has gone off and not clean, it is not allowed to use.

(3) as to the main bearing which has just been installed and put into use
new ,we should replace them after the ball mill operating
a month later, the lubricant should be all escaped (reducer should be performed
in accordance with the relevant technical documentation) ,clean the oil tank and
replace with new oil.
(4) we should check the main bearing seal
regularly, pay attention that whether the oil scraper brush, scraping the
oil-plate workpiece is normal, both ends of the felt seal is good, if necessary,
adjust or replace them.
(5) regular check whether the cooling system is
smooth.
(6) pay attention to the checking feed device, a feeding device,
the seal of the gear cover, badly worn or be affected by the sealing effect,
should be adjusted in a timely manner, replace, or take other measures to
complement the grease.
(7)pay attention to listen the moving parts of
the reducer bearings, the size of gear noise and vibration in operation. (8)
pay attention to check the liner connection bolts, anchor bolts, etc. if there
are loose, broken off an
d other phenomena. New replacement bolts to running
after a certain time after installation or repair, re-tighten.
(9) Note
that the signal of a variety of instruments, lighting fixtures and control
system is sensitive and complete.
(10) on a regular basis to stop
grinding check: in order to detect defects, and eliminate the fault, in order to
ensure the normal operation of the mill, in addition to routine maintenance, but
also preventive stop grinding, periodic inspection and make a record, in order
to respectively severity appropriate process and prepare a maintenance plan.

(11) mill component wear to the following circumstances should be replaced:
a liner thickness of wear and tear by 70%, or 70mn cracks. b, the lining of the
bolt head wear, liner loosening, c. Main bearings, spherical bush when you have
a leak, to replace the spherical bush. d. Hollow shaft of the crack should be
timely. e main bearing babbitt badly worn or crushed, replaced with new bolts.
We must be re-cast the babbitt.
