Ball mill is a key ore beneficiation machine, used in smashing the material. It is widely used in cement, silicate products, and new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramics production industry. It can grind a variety of ores and other grind-able materials, has dry or wet grinding two types.
In the daily production process, ball mill’s maintenance is a recurring work,
which directly impacts the rate of operation and service life of the grinding
mills. In order to detect defects and eliminate hidden dangers, in order to
ensure the normal operation of the ball mill, in addition to the daily
maintenance, but also need regularly stop grinding (recommended once a month) to
check hollow shaft, main bearings, cylinder, reducer, size gear and so on, then
do the detailed records.
Some information for choosing balls:
when the hardness of the material is big, try to choose a larger diameter
when mill diameter and impact is greater, try to choose a smaller steel
using the dual position separators, its ball diameter must be smaller than
that of the single-layer diaphragm plate of the same discharge
Preparatory work before the ball mill operation: cleaning the inside
workshop, the tools, used in construction should be completely evacuated.
Check the cleaning of the ball mill itself:
if the internal part of ball mill has articles and debris;
if the discharging hole of the ball mill and vacuum tube has debris;
if the bearing and the outer cylinder of ball mill clean;
make the coupling parts, ball mill bearing, reducer, motor clean;
blow the compressed air of the motor away , check if the interior of the
motor has debris.
before the ball mill operation, first make high-pressure oil pump operate,
use the high-pressure oil film to hold up the ball mill, forming a floating, and
reduce the torque of the ball mill, then put the oil into ball mill bearings and
check if the cooling water pipe has clogging, before test ball mill, open
cooling water pipe joints, and flush the pipe until the cooling water is
