的固定且可自转的磨辊组成。
需粉磨
的原煤从磨煤机的中央落煤管落到磨环上，
旋转磨环借助
于离心
力将原煤运动至碾磨滚道上，
通过磨辊进行碾磨。
三个磨辊沿圆
周方向均布于磨盘滚道
上，碾磨力则由液压加载系统产生，通过静定的三点系统，碾磨力
均匀作用至三个磨辊上，这
个力经磨环、磨辊、压架、拉杆、传动盘、减速机、液压缸后
通过底板传至基础（见图

―

）
。
原煤的碾磨和干燥同时进行，
一次风通过喷嘴环均匀进入磨环周围，
将经过碾磨从磨环上切向
甩出的煤粉混合物烘干并输送至磨煤机上部的分离器，
在分离器中进行分离
，
粗粉被分离出来
返回磨环重磨，合格的细粉被热一次风带出分
离器。
2. Grinding principle of
the ZGM mill
ZGM mill is a vertical
mill with three grinding rollers and one grinding
track. A grinding table
rotates round a
vertical axis in driven by a planetary gearbox.
The three grinding rollers, mounted in
fixed position, are passed down on the
table under hydraulic loading. Raw coal enters
through the
center
of
the
mill
and
is
deposited
on
the
grinding
table.
Centrifugal
force
feeds
the
coal
radially
outward where it is ground between the
roller tyres and grinding track.
The
grinding
force,
is
statically
determined
by
three
grinding
rollers,
which
is
generated
by
hydraulic
loading.
The
transfer
loop
diagram
of
grinding
force
is
shown
in
Fig1-1.
It
starts
from
loading, to grinding rollers, grinding
track, towards the foundation.
The
pulverized
coal
is
flowed
by
centrifuged
force
into
the
zone
over
the
nozzle
ring
surrounding the table, where the coal
particles are swept upwards by the stream of hot
primary air
into the classifier.
The intimate contact with the hot
primary air causes the moisture
contaminated in the coal to
evaporate spontaneously. The oversize
particles rejected by the classifier fall back
onto the grinding
table
for
further
grinding.
The
fine
particles,
i.e.
finished
product,
are
carried
out
of
the
classifier
with the air.

Pyrites and tramp iron that
cannot be carried upward by the primary air drop
down through the
ring and into the

型磨煤机采用鼠笼型异步电动机驱动。通过立式伞齿轮行星齿轮减速机传递磨盘
力矩。
减速机还同时承受因上部重量和碾磨加载力所造成的水平与垂直负荷。
为减速机配套的润滑油站用来过滤、
冷却减速机内的齿轮油，
以确保减速机内部件的良好
润滑状态。
配套的高压油泵站在运行时通过加载油缸对磨煤机进行加载和升降磨辊。
通常一台磨配有一台密封风机，也可几台磨
(
一台炉
)
共用一台密封风机，密封风用于磨煤
机传动盘处、机壳拉杆密封处和磨辊处的密封。如果采用旋转分离器，则旋转分离器处需要密
封风。
维修磨煤机时，在电动机的尾部连接盘车装置。

Classifier
（
20MG10.11.15
）
There are two
types of Classifiers, one is static baffle
separator, the other is rotary classifier.
The static
baffle separator can endure a pressure for
exploding is 3.5 bar. The main parts consist
of classifier casing, baffle door,
inside cone, handling setting for baffle door, out
way of the powder,
and
coal
intake
pipe.
The
function
of
the
classifier
is
selecting
powders
whose
sizes
meet
the
requirement of the
boiler. Throng adjusting the angle of the baffle
door, the sizes of powders can be
controlled.
The
scope
of
the
adjusting
angle
is
25
°
~80
°
,
the
size
of
particular
can
be
adjusted
ranging between
R
90
10% to 40%, the working
angle commonly is 50
°
, but
the best angle need to
be confirmed by
mill performance experiment.
The rotary classifier of dynamic and
static type mainly consist of classifier casing,
static shutter,
rotor, pipe of
transmission coal,
drive parts,
cone of
collecting powder,
seal
pipe
etc.
The dust/air
mixture comes into the
classifier, first through the static shutter,
where the coarse dust particles are
separated
and
return
to
the
grinding
space.
Whilst
the
others
are
led
into
the
rotor
space
by
the
traction,
the centrifugal force of eligible particles equate
with the traction by adjust the rate of rotor,
but the unqualified dust particles are
driven to the grinding space by the centrifugal
force. When the
speed
of
the
rotaty
classifier
rotor
is
40~140rpm,
the
size
of
particular
can
be
adjusted
ranging
between R

2%
to35%. The motor is to be driven by the
transducer, then the center hollow shaft is
transmitted by gear and rotary support,
thereby the rotor is rotated. The suitable rotary
speed need to
be confirmed by mill
performance experiment.

3.17seal air pipes
（
< br>MG10.11.17
）
The seal air from seal fan is separated
into roller seal space, tie rod seal space and
Base seal via
non return valve on the
bus pipe. The seal air of grinding rollers go into
mill from top of classifier
bottom-
flange, then into 3 yoke via circular air pipe and
vertical air pipe with joint bearing. In order
to prevent the inflection for grinding
liberation, one end of vertical air pipe is fix on
the yoke, the
other end is connected to
the circular air pipe. The steel cover jointed to
bearing is prone to wear for
the
inflection of the swing of joint bearing,
therefore it often must be inspected and
maintained, if
need, it must be
changed. There is a butterfly valve for adjusting
the volume of seal air.
If
the rotary classifier is equiped, the rotary
classifier needs some sealing air.

概述
4.1 General
为防止磨煤机内煤粉自燃或爆炸，在
操作运行中必须严格遵守有关操作规程和说明。
In order to prevent dust fires and dust
explosions, the relational regulation and the
safety
rules must be observed in
operation.
磨煤机检修时，必须要有挂牌制度，必须停磨并关闭磨煤机入口
和出口阀门。检修过
程中要严禁电动机合闸，要严防危及人身安全的事故因素发生。
The

of
the
mill
must
be
shut
during repairing, meanwhile motor is
forbidden to switch on. Prevent the accident
endangered

运行时，应确保关闭防爆消防气体通入管道上的电动阀门关闭，手动阀门打开。
During work at the mill, it has to be
ensured that the electric valve of inert gas inlet
cannot
be switched on and the manual
valve should be switched on.
磨煤机能够把一定粒度
的原煤碾磨成合格的煤粉，但不容许诸如金属块、石块、木块
和其它粗硬异物进入磨煤机
内，否则将影响磨煤机的使用寿命；也不容许棉丝、铁丝、炮
线等杂物进入磨煤机内，因
为这些条状、线状杂物会缠住分离器的转子、静叶挡板等，影
响分离器的正常功能以及引
起煤粉存积而着火。所以，输煤系统应具有完善的清除杂物的
设施。
The mill has the task to crush hard
coal of one size to pulverized coal. But, foreign
matters,
such
as
metal
substances,
stones,
blocks,
and
coarse
foreign
materials
can
interfere
with
the
employ
life of the mill and cause damages. Thus, those
parts are not permitted in the mill. The
strip and line type foreign matters
cannot get into the mill that can entwine the
classifier rotor,
static vane baffle
etc., since these not only interfere with the
function of the classifier, but also
cause
a
risk
of
fires
by
producing
dust
deposits.
Therefore,
the
perfect
sundries
cleanup
establishment should be provided to
transmitting coal units.
碾磨部件（耐磨件）采用高铬铸
铁制成，此种材料易脆裂、易热裂。所以要避免碰撞
冲击和加热。中速辊式磨煤机除低速
盘车外，只容许磨辊与磨盘衬板之间调整出间隙后启
动，或把磨辊抬起后，或磨盘上布定
量煤后启动；绝不容许磨盘上无煤而磨辊与磨盘衬板
接触时启动。
The

–
grinding
rollers
tyres
and
grinding
table
segments-
are
made
of
materials
of
high
hardness
and
corresponding
sensitivity
to
breakage,
therefore
these
prevent
from collision, impact and heated. For
this reason, it is not permitted to operate the
mill unless
the
mill
operates
at
the

air may be properly adjusted from standard,
therefore,
while
the Mill
Technical Protocol
is being subscribed,
the user may constitute the “standard air
curve” according to the request of
boiler factory and design institute, in order to
insure that the
hot air quantity adapt
to the system. Because of the different of the

the Mill
Technical Protocol
.
< br>建立正确的给煤量和一次风量比率是很重要的，如果标定的一次风量、给煤量不准，
不但影响负荷调节，而且影响磨煤机运行。所以在磨煤机初次运行前，应对照标准空气
曲线校对给煤量和一次风量的比率，认真检查标定的给煤量和一次风量是否准确。运行
期
间应定期校对测量装置，防止测量装置出现质量问题使标定的给煤量和一次风量失准。
It is very important to set up proper
scale of the quantity of supply coal and hot air.
Unless
the
quantity
of
supply
coal
and
hot
air
is
exact,
not
only
the
adjusting
of
load
but
also
the
operation of mill will be effected.
Therefore the scale of the quantity of supply coal
and hot air
should
be
inspected
according
to
the
curve
during
the
first
operating.
Then
the
measure
equipment should be proofed termly, in
order to prevent the quality trouble that measure
is not
exact.
注意：在磨煤机运行初期，一次
风量自动调节尚未投入，由运行人员手动调节磨煤机
出力时，应做到增加磨出力时，先加
风量，后加煤量。降低出力时，先减煤量，后减风
量，以防止一次风量调节过快或风量过
小造成石子煤量过多，甚至堵煤。

the risk of deflagration at warm mill.
2.2.2
对磨煤机内部进行清理工作，检查磨内（碾磨腔、
一次风室、分离器）是否有安装工具、
粗大物体、布块杂物、
纤维或其它杂物，如有应消除。检查旋转喷嘴部位与粗粉导流环之间是
否有杂物，清理存在的杂物，否则在磨煤机运转时产生噪音，引起不必要的误会。
2.2.2 Inspect internal mill space
(grinding space, hot gas guide part, classifier)
for mounting tools,
foreign
matters, coarse impurities, cloths, cleaning wool,
or other rubbish; remove, if required.
2.2.3

际
操作时，建议在第一次换油时间，通过对润滑油成份的逐项分析、粘度检验、测量油的综合
指标，并在运行期间选择较短的时间间隔来检验润滑油的杂质并观察油质情况。
2.2.3 Oil change at the grinding
rollers
The oil change is made with
mill being put out of operation and according to
the enclosed list of
lubricants (see
list 2). The oil changing periods stated in the
list of lubricants are approximate values.
It is recommended to observe change of
the oil quality during the first operating period
by successive
oil analyses, by checking
the viscosity, by measuring the neutralization
index, and by checking the
lubricant
for impurities to choose shorter intervals between
the oil change, if required.
2.2.3.1
旧油的排放
旧油排放是通过固定在朝向磨煤机中心侧的磨辊辊芯上的三个螺塞中的一个进行的。排放
旧油时，应将圆柱滚子轴承及双列调心滚子轴承内的旧油同时排出。请务必不要拆卸封闭的轴
承端盖来排放磨辊辊芯中的润滑油，在排油前，应用盘车装置将一个排油螺塞调至最低点。排
出的旧油应盛放于适当的容器中。旧油排净后，重新拧紧螺塞并用锁紧圈锁住防止松动。
2.2.3.1 The draining of the
used oil is made through one of three screw plugs
attached to the grinding
roller hub towards the internal mill
place; during this, not only the space of the
cylindrical roller
bearing
but also that the spherical roller bearing are
drained. Do not remove the closed bearing cover
to drain the grinding
roller hub in any case. Prior to the draining, set
chosen drain plug by means of
the barring gear to its lowermost
position. Collect the used oil in suitable tanks.
After draining,

Remove cover of probe
protection box.
③
Remove the
drain plug of the bore for the oil dip rod at the
grinding roller shaft;
④
In
order to increase the flow properties of the fresh
oil to be filled in, it is expedient to heat it
up to approx.50
0
C (according to the
recommendations of the oil supplier).
⑤
The fresh oil is filled in
from outside by means of a corresponding device
(funnel, hand pump)
connected through
the inspection cover opening to the oil dip rod
bore at the grinding roller
shaft. Take
care of good ventilation (clean ventilation
filter, if required).
⑥
The
oil volume to be filled in is monitored by the aid
of the oil dip rod and/or the measuring
probe (The max. oil volume is to be
filled in ).
⑦
Retighten

oil dip rod.
⑧
Install cover of probe
protection box together with seal.
⑨
Close inspection cover
tightly.
⑩
Repeat this
filling procedure for the two other grinding
rollers
2.2.4
碾磨件的检查
磨辊辊套和磨环衬板的
工作表面因碾磨作业会产生磨损，这种磨损使辊套和磨环衬板的外
形改变。因此，在磨煤
机停机时应对其磨损情况进行检查。磨环衬板磨损情况的测量应在整个
磨环圆周上均布的
三点上进行，测量时应将测点处清理干净；辊套的测量应测量圆周上相对的
两点。
每运行
1000
小时测量一次磨损情况，
测量结果用户可用来预测碾磨件使用寿命及编制备
件计划。耐磨件是
高铬铸铁制造，对温度的急剧变化十分敏感，因此绝不能在磨机刚停下来，
为尽快开始维
修作业而用水或压缩空气来冷却磨辊。
注意事项
：碾磨件更新后，经短时间运行后，必须对磨环上的所有紧固螺栓进行检查，必
要时应重新拧紧。
2.2.4 Inspection

2.2.5
机壳导向装置
检查导向装置（导向块
及导向板）的间隙。并保证压架的垂向灵活运动，随着磨煤机的运
行时间的增加，压架和
机壳上的导向块及导向板之间的间隙会逐步增加，这会引起磨煤机运转
的不稳定，因此每
次检查磨煤机内部时，应检查测量该间隙并加以记录。当该间隙增加到
8mm
以上时需要加垫片调整，
以恢复到原始安装位置，
垫片设计成可从侧面或上面将其推入的形式。
如果在导向块或导向板上出现阶梯磨损现象
时，会妨碍压架的自由运动，这时候应予更换。
2.2.5
Guide devices
At each mill inspection
the thickness of the thrust wear plates has to be
measured and recorded.
In course of
time, the clearance at the tangential support
between the thrust wear plates at the guide
devices may increase. This can result
in an unbalanced running of the mill. The thrust
wear plates at
the casing have to be
lined with suitable sheets of adequate thickness
at the latest, when the clearance
has
increased to 8mm. The lining sheets are to be
designed in a way that they can be pushed from one
side under the thrust wear plates
subsequent to loosening the fastening screws. The
thrust wear plates
have to be replaced,
if a stepped wearing condition should occur at
them which could restrict the free
movement of the loading frame.
2.2.6
磨辊密封风管
对密封管路中磨辊密封风的管路磨损、紧固及关节轴承有无运动阻碍等情况进行检查。
2.2.6 Roller sealing air

2.2.8
石子煤排除
在运行初期应经常检查，
至少每两小时一次，必要时应增加检查次数，其周期长短应根据
石子煤量来定。石子煤量
取决于煤种的性质，磨煤机出力及磨煤机运行方式。此外，石子煤量
也受到喷嘴环出口风
速影响。通过提高喷嘴环出口风速的方法可减少石子煤量，但可能增加零
部件磨损。喷嘴
环出口风速可通过改变其出口截面积来控制。在磨煤机启动和停机时，石子煤
量的增加是
正常现象。由于一次风室没有储存石子煤的能力，因此不允许磨煤机在不排渣的情
况下长
时间运行。
2.2.8 Reject Box
In the beginning, frequent inspections
–
at least once two hours,
but more frequently, if required
–
are
necessary.
The
inspection
period
depends
on
the
resulting
reject
volume
and
on
the
storage
volume
of
the
reject
box.
The
reject
volume
depends
on
the
characteristics
of
the
material
to
be
ground,
the
mill
throughput,
and
type
of
operation.
In
addition,
the
waste
volume
can
be
slightly
affected by the outlet velocity of the
nozzle ring. A reduction of the reject volume can
be obtained by
increasing the outlet
velocity of the nozzle ring; on the other hand,
the increased outlet velocity at the
nozzle ring can cause an increased wear
at the mill. The nozzle ring outlet velocity can
be controlled
by changing the nozzle
cross sections. In the beginning or putting out of

测量装置
测量装置只能在磨煤机停机和碾磨件之间没有煤的情况下调整。利用该装置，我们可以从
磨煤机外部判断出下列情况：
①
磨辊辊套和磨环衬板的总磨损量
②
煤层厚度的变化
使用测量装置前应将
其调好，调整程序为：将拉杆上的测量圆环的尖点对准测量标尺的零
点后，将其紧固。当
磨煤机运行时，磨辊与磨环间进入一定的原煤，使拉杆上升，测量圆环也
随之上升一定距
离，将标尺的“煤层厚度”滑块的中心刻度对准圆环尖角，便可看出磨内煤层
的厚度及变
化，并可估算碾磨件的磨损量。当磨煤机磨环上无煤时，从标尺上便可看出碾磨件
的总磨
损量的近似值。
