The grinding materials of the vertical mill are generally divided into coal dust, cement raw materials, slag, sandstone and the like, and different vertical mills and powder selectors matched with the different vertical mills are selected according to the requirements of material characteristics, product yield and the like. The middle-sized and small-sized powder selecting machine adopts a central blanking mode, and has the advantages that accumulated materials cannot be generated, such as the powder selecting machine for coal mill, and the transmission mode adopts belt transmission; the large powder selecting machine, such as cement raw material and cement clinker vertical mill, has large rotor part diameter and higher vertical height, needs to consider the stability and reliability during operation, and needs to consider designing a proper transmission structure besides adjusting the supporting structure of the rotor so as to not only meet the mechanism change of the rotor, but also ensure the stability and reliability of the operation of the rotor with large inertia.

The driving motor 101 is an ac variable frequency motor equipped with a frequency converter and an adjusting pad 102.
The speed reducer base 304 is provided with an observation door 304a and an access door 304b.
The powder concentrator driving device adopts a speed reducer direct connection transmission mode, the driving is driven by a driving motor 101, the driving motor 101 is arranged on a motor base 202 and is fastened by four bolt holes, when the powder concentrator driving device is arranged, the distance between the shaft end of the driving motor 101 and the shaft end of a speed reducer 303 is adjusted through a motor position adjusting mechanism 201, the length and the size of an elastic coupling 301 are matched, and the center of the driving motor 101 and the center line of an input shaft of the speed reducer 303 are adjusted to be on the same line; the motor base 202 adjusts the center height of the driving motor 101 and the levelness of the motor base 202 through the motor level adjusting mechanism 203. The motor horizontal adjustment mechanism 203 is that four bolts are distributed around the motor base 202, because the upper shell of the powder concentrator is of a welded structure, and the structure is large in size, and in addition, deformation is possibly caused in the installation process, the top of the upper shell of the powder concentrator is not suitable for being designed into a processing surface, so that the levelness and the height of the uneven surface can be adjusted in a mode of adjusting bolt support. After the adjustment, the motor is fixed by the motor base fixing device 204.
The driving motor 101 is connected with the end of the speed reducer 303 through an elastic coupling 301 to transmit torque. Since the motor output end rotates at a high speed, the elastic coupling 301 needs to be provided with a protective cover 302, so that accidents are prevented, and meanwhile, the elastic coupling 301 is sealed and protected. The protective cover 302 is of a detachable structure, so that the installation and maintenance are convenient.
One end of the speed reducer 303 is connected with the driving motor 101, and the other end is connected with the central shaft of the rotor bearing seat. Since the rotor is vertically installed, the speed reducer 303 needs to be vertically arranged and horizontally installed, and when the speed reducer 303 is selected, an independent lubrication and cooling mechanism needs to be provided, so that the sealing performance is good, and the outdoor environment can be adapted.
The coupling 307 at the output end is directly connected with the powder concentrator rotor, and an elastic pin coupling is adopted, so that impact is eliminated, and noise is reduced. Because the rotor is vertically arranged and rotates in the horizontal direction, the working environment reaches 80-90 ℃, the floating and thermal expansion of the axis direction of the rotor shaft are fully considered, a certain gap is reserved between the upper part and the lower part of the coupling 307 at the output end, and the expansion coefficient of the elastomer also meets the requirement.

The device can measure the real rotating speed of the rotor on line in real time and can provide an alarm signal when the transmission device is abnormal or extremely.
As shown in fig. 4, the lower portion of the protective cover 302 is supported on the connecting device 205 by a transition support 302 a. The transition support 302a can be welded and fixed after the proper height and front and back positions of the protective cover are adjusted during installation, so that the flexibility is high.
As shown in fig. 5, a group of adjusting gaskets 102 can be added for adjusting the height of the driving motor 101, and after the motor base 202 is fixed, the center line of the adjusting motor and the center line of the input shaft of the speed reducer 303 are on the same line, so that stable transmission is ensured.

The reinforcement is performed by adopting a flat steel bar edge-wrapping welding mode, namely, the periphery of the motor base 202 is wrapped by a flat steel bar for a circle, and then the motor base is welded with the top of the upper shell of the powder concentrator at the installation site. The amount of thermal deformation needs to be strictly controlled during welding.
