当增加选粉机转子的转速，可以生产更细的成品。这个效果也可以通过调整（加大）动态选粉机的导风叶片的切线角得以实现和加强。反之，当降低选粉机转速或者调整选粉机的导风叶片至径向方向时会生产出较粗的料。
Basic setting of the SEPOL guide vanes is with an angle of 60 to 70° referred to the radial line, and the long guide vane shank points to the inside. Commissioning of the SEPOL is at a rated speed of 85 to 90 % (approx. 30 m/s of circumferential speed). The speed is then ad-justed according to the produced fineness of the finished product. SEPOL导风叶片得基本设定是与径向成60~70°角度，并且导风叶片长柄向内指。SEPOL试运转速率在85~90%(圆周速度大约30米/秒)。然后根据生产产品的细度调整速度。

1.1.4 Gas routes 热风管路
A hot gas generator (item 5F1.HG01) is provided for combined grinding and drying. It produces exhaust gas temperatures of approx. 800°C. Before entering the mill, the hot gas is cooled down by admixture of circulating mill air. The circulating mill air volume is controlled by means of the throttle valve (item 5F1.TV01).
热风炉(项目号5F1.HG01)提供热风用于粉磨系统干燥。它产生的热风温度大约800°C。在进入磨机前，热风与磨机循环风混合后冷却。磨机循环风量通过节流阀控制(项目号5F1.TV01)

Considering the risk of incrustations for slag grinding, a certain amount of the hot gas sup-plied by the hot gas producer is used for heating the recirculating bucket elevator (item
5F1.BE01), the feed chute and the rotary airlock feeder (item 5F1.CV01.CVJ01). The gas for heating the recirculating bucket elevator is taken from the hot gas generator and mixed up with fresh air to approx. 250°C. The throttle valve (item 5F1.TV03) controls the hot gas flow rate whereas the fresh air flap (item 5F1.TV02) controls the temperature for heating up.
Heating of the rotary airlock feeder and feed chute is not subject to control and hand-operated flaps are used for adjusting purposes.
考虑到矿渣粉磨过程中存在结料的问题，由热风炉产生的部分热风用于加热循环提升机(项目号5F1. BE01)、喂料料槽和旋转锁风喂料机(项目号5F1.CV01.CVJ01)。用来加热循环提升机的热风从热风炉来并和新鲜空气混合到大约250°C。节流阀(项目号
5F1.TV03)控制其热风风量，而冷风阀(项目号5F1.TV02)控制加热风温度。旋转锁风喂料机和喂料料槽的热风加热比较不容易控制，故用手动挡板为调整。
The finished product leaves the mill together with the gas stream from the SEPOL separator. To protect the downstream bag filter, the bag filter is internally equipped with a fresh air flap. As soon as the filter-specific, maximum temperature is exceeded, this flap will open and cooler fresh air is admixed to the gas stream.
成品和气流一起从选粉机离开磨机。为保护下一步的收尘机，收尘机内装有一个冷风风阀。当进收尘机风温超出温度上限，风阀就会打开，冷空气混入进收尘器的气流中。
The louvre damper (item 5F1.FN01.TVJ01) downstream of the filter controls the gas quantity flowing through the mill. The return air duct downstream of the mill fan (item 5F1.FN01) re-turns the gas to the mill inlet, and the excessive gas is discharged through the stack (item 5F1.GP03) into the atmosphere.
百叶阀(项目号5F1.FN01.TVJ01)位于收尘机之后，控制着通过磨机的总风量。磨机风机之后的循环风管把热风送回到磨机进风口，过量部分的风量通过烟囱(项目号5F1.GP03)排入大气中。
1.1.5 Finished product route成品路径
In the bag filter (item 5F1.BF01) the finished product is separated from the gas stream. Then, the screw conveyors and the rotary airlock feeders under the bag filter convey it to the con-veying equipment for finished product which conveys the finished product to the silos. Then a conveyor and a bucket elevator transport the finished product extracted from the silos either to the mixing station –where it is mixed with clinker dust- or to the loading station, as re-quested.
在袋式收尘机(项目号5F1.BF01)内成品和气流分离。位于袋式收尘机之下的螺旋输送机和旋转喂料机将成品送入库中。然后通过输送设备提升机从库中选取成品根据需要送往搅拌站，在这里与熟料粉拌合，或者送往装车站。
1.2 Control concept 控制原理
In principle, several machines with their drive units are combined to form useful start-up groups. Under normal operating conditions, the whole group is centrally operated from the control panel in “automatic“ mode. This means, it is possible to start and stop this group pro-vided the switch-on and switch-off conditions have been fulfilled for the respective group and the individual drive units of this group. Generally, the start-up of a group follows a certain sequence. Usually, additional machine protection conditions and process-technological inter locking conditions must be taken into account for the start-up of a group. A message is displayed after the start-up of a complete group, and possibly the start-up of the following group is enabled.

原则上，几台设备的驱动装置整合起来形成联锁起动组。在一般的操作情形下，整个组在“自动模式”下在控制中心通过控制盘操作。也就是说，只有相关组的‘开’、‘停’条件以及该组内各设备的‘开’、‘停’条件满足，则可以进行该组的启动/停止操作。组的启动或停止操作遵循一定的顺序。通常，组的启动/停止操作要考虑到相关设备的保护条件和工艺过程的联锁条件。在一组设备启动/停止的完毕信息显示后，才有可能进行下一组设备的启动/停止操作。
Alternatively it is possible to operate the drive units of a group individually or in groups, lo-cally in the “local“ mode.
一组设备可以选择组内各设备的单机操作，也可选择组设备操作。现场操作需把系统设置到现场模式。
In the “automatic“ mode, however, the protective machine interlocks ( PMI ) as well as the process-technological interlockings ( ILC ) are active either for the complete group or the respective drive units.
在自动模式下，不管是整组操作还是单一设备操作，设备的保护联锁( PMI )和工艺过程联锁( ILC )均起作用。
Belong to the PMI among others :属于PMI（设备保护联锁）的包含其中： _ Motor winding temperatures马达运转温度 _ Gear oil temperature齿轮油温 _ Oil level油位 _ Oil pressure油压
_ Emergency switch紧急开关
_ Local/remote selector switch (“automatic“ or “local“) 现场/自动选择开关(“自动”或“现场”)
Examples for interlockings (ILC) are : ILC（工艺联锁）的例子
_ Message that the next group in flow direction of the material is in operation 在物料流程上下一个组的运转信号 _ Off-track belt switch 皮带跑偏开关 _ Bearing temperatures 轴承温度
_ Min/Min level or Max/Max-level最低或最高料位 _ Temperatures 温度 _ Pressures 压力
Is the local mode of operation of the drive units selected locally, this condition must be en-abled from the control panel. In local operation it is then possible to locally start or stop the respective drive unit of the respective group by means of the local/remote selector switch without operational or process-technological inter locking being active. Merely the protective machine interlocks (PMI) remain active to protect operators and machines.
要想在现场操作设备，需在控制操作台选择现场操作模式。在现场操作，可以通过现场/中心选择开关，对组内的的各个设备进行开/停操作。一般没有操作或工艺联锁，只有设备的保护联锁(PMI)保留激活以保护操作者和设备。
The local/remote selector switches installed in the vicinity of machines normally have the following positions: 现场/中心选择开关安装靠近设备，通常有如下位置： _ Stop 关
_ Automatic (or even Remote) 自动(或者中心)
伯利休斯水泥 第 23 頁，共 37 頁
_ Local 现场
Moreover, the local/remote selector switch can be turned by hand from the “local“ position to the “start“ position and be kept there until the motor contactor picked up and the drive unit starts running. Afterwards the switch can be released and returns to the “local“ position. In the case of reversible drive units or actuators for flaps there are, instead of the “start“ position of the local/remote selector switch, two further positions for the respective sense of rotation of the drive unit.
此外，现场/中心选择开关可以手动旋转从“现场”位置转向“启动” 位置，保持住直到马达接触器投入作用并且设备运行为止。其后开关可以松开并回到“现场”位置。如果是正反转设备或是阀门电动执行机构，现场/中心选择开关的开启位置换成2个相应的旋转方向或阀位指示。
Return of the switch to “automatic“ mode is possible at any time in order to ensure that a lo-cally started drive unit is available again in automatic mode via the control system, and the complete group can be started once again from the control panel.
在任何时候打回开关至“自动”模式是为了确保一个现场运转的转动装置通过控制系统回到自动模式，并使整个组可以从控制盘再次被起动。
Operation of the drive unit is stopped immediately in the switch position “stop“ irrespective of the fact whether operation of the drive unit had been started via the control system in auto-matic mode or locally in local mode. In this switch position the drive unit is not available on the control panel and cannot be started there.
开关打到停止位置时转动装置的操作会马上停止，而不论转动装置是通过控制系统在自动模式或是现场模式启动的事实。在这个停止位置设备不能从控制盘上被启动。
All in all, the following groups can be defined for operation in a precisely defined way from the control system: 总之，下面的几组设备的操作，从控制系统的说明中能得到准确的操作控制程序说明：
_ Gearbox lubrication (5F1.RM01.GLS01) 减速机润滑 _ Auxiliaries 辅助设备
– Hydraulic system (5F1.RM01.HYS01) 液压系统
– Separator drive unit (5F1.RM01.SDR01) 选粉机传动装置 – Coarse feed valve (5F1.CV01.CVJ01) 粗料进料阀
– Removal of fine iron particles (5F1.MG01.MGJ01)小铁颗粒的去除 – Recirculating bucket elevator (5F1.BE01)循环式提升机
– Confining air fans (5F1.RM01.CAS01 and 5F1.RM01.CAS02)空气密封风机 _ Finished product conveyance成品输送 _ Gas routes (5F1.GP01 to 5F1.GP05) and
separation of finished product (5F1.RM01.SDR01)气体通路和成品分离 _ Hot gas producer (5F1.HG01)热风炉
_ Main drive unit of mill (5F1.RM01.DRU01) and fresh material conveyance 磨机主马达和原料输送
_ Water injection (5F1.RM01.WTJ01)喷水
1.2.1 Control of gearbox lubrication (5F1.RM01.GLS01) 减速机润滑控制
A hydrodynamic lubrication system is concerned which uses a low-pressure oil pump to sup-ply oil to the individual lubrication points in the gearbox (gear wheels, bearings, etc.). 液压润滑系统使用一台低压油泵供油给减速机的各个润滑点(齿轮，轴承等)
伯利休斯水泥 第 24 頁，共 37 頁
The lubrication system represents a compact unit with 润滑系统组合地集成以下部件： _ oil tank and level indicator 油箱和液位指示 _ low-pressure oil pump低压油泵
_ heat exchanger for indirect oil cooling, using cooling water 水冷式冷油热交换器 _ thermostat-controlled immersion heater with resistance thermometer 浸入式热电阻温控电加热器
_ disk filter as change-over duplex filter with differential pressure monitor 差压监控可换式双路圆盘式过滤器
_ flow monitor in the low-pressure oil circuit低压油循环流量计
_ 2 pressure switches in the low-pressure oil circuit 低压油循环回路上的2个压力开关
including several resistance temperature sensors installed in the gearbox for measuring the bearing temperature, etc.
包括数个安装在减速机上热电阻，用于测量轴承温度等。
As the oil employed for lubricating various points must have a certain temperature and viscosity, the gearbox lubrication control system also controls the thermostat-controlled
heater and the oil cooling system. As, usually, the oil must be heated up for the start-up phase, the gearbox lubrication system will be started as group in automatic mode several hours before starting mill operation, and it will continue operation even during shorter mill stops. Only for planned mill stops of more than 30 hours, necessary repair or maintenance work it will be expedient to stop operation of the gearbox operation system.
由于润滑的各个点的油必须有一个合适的温度和粘度，减速机润滑控制系统同样控制温控电加热器和油冷却系统。通常，润滑油必须加热至可运行状态，在自动模式下，减速机的润滑系统需在磨机启动前几个小时就开始运行。并且在磨机短暂停机时也会保持运转。只有计划停磨超过30小时的必须维修或维护保养工作时，才会考虑停止减速机的润滑系统。
Alternatively, it is possible to locally start in “local“ mode operation of the low-pressure oil pump for test purposes or to stop it.
也可选择在现场模式启动/停止低压油泵，为了测试目的。
1.2.2 Control of auxiliaries 辅助设备的控制
The grinding force required for material comminution is produced by a hydraulic system and transmitted onto the grinding rollers by means of tie rods. The hydraulic system allows con-tinuous adjustment for the purpose of bringing the grinding force into line with the operating condition of the mill.
对物料粉磨所需的碾磨压力由液压系统产生，通过拉杆传递到磨辊上。为了适应磨机的操作需要，液压系统在磨机运行中可连续的调整压力，以提供稳定合适的碾磨压力。
For starting the roller mill, the grinding force is reduced by lowering the hydraulic pressure. By this measure, the starting torque of the main drive unit of the mill is reduced accordingly. The following functional steps are executed when starting the hydraulic system of the mill: 启动磨机时，液压系统降低磨辊的压力，这样，主电机的启动扭矩就相应减少。当开启磨机的液压系统时，按以下步骤进行：
_ All solenoid valves are in a de-energised condition (items 5F1.RM01.HYS01-M6101 to 5F1.RM01.HYS01-M6108). 所有的电磁阀均在失电状态。
