1. Brief introction: Hebei Beikuang mining Machinery Manufacturing Co., Ltd. is a high-tech enterprise procing rubber spare parts for mining equipment. After ten years of hard work, it has become a company with strong development and full innovation integrating research, development, proction and sales. The company is located in Longhua Development Zone, Jingxian County, Hengshui County, Hebei Province, covering an area of more than 70 mu, with a fixed investment of 40 million yuan and a total investment of 60 million yuan. The company now has two rubber vulcanization workshops, a foundry workshop, a machine tool processing workshop and a number of advanced testing equipment. The structure of BF flotation machine is shown in the figure, which is mainly composed of impeller, cover plate, main shaft, central cylinder, tank, etc. The whole impeller structure is installed on the main beam of the tank and driven by the motor through the V-belt. The structural feature of this machine is that the impeller is composed of closed double cone, which can proce strong pulp circulation. The machine can also be equipped with pulp automatic control device to adjust the liquid level. BF type flotation machine is suitable for the separation of ferrous metals, as well as non-metallic minerals such as coal fluorite and talc. It is widely used for the separation of gold, silver, copper, iron, tungsten, lead, zinc, tin, molybdenum, nickel, tantalum, niobium, manganese ore, coal and other non-ferrous metals. It can also be used for the roughing and cleaning of ferrous metals and non-metallic minerals. When the impeller of KYF aerated mechanical stirring flotation machine rotates, the pulp in the cell is sucked into the impeller blades from the bottom of the impeller through all sides. At the same time, the low-pressure air from the blower enters into the air distributor of the impeller cavity through the air ct, air control valve and hollow spindle, and enters into the impeller blades through the holes around the distributor, After the pulp and air are fully mixed between the impeller blades, they are discharged from the upper part of the impeller, and the discharged ore flows upward. After being stabilized and oriented by the stator installed at the upper part of the impeller, they are dispersed into the whole tank. The mineralized bubbles rise to the surface of the trough to form foam, and the foam flows into the foam tank. The slurry returns to the impeller area for recycling, and the other part enters the lower trough through the flow holes on the wall to carry out the re election. When the impeller of SF flotation machine rotates, the pulp in the upper and lower impeller cavities is thrown around by centrifugal force under the action of the upper and lower blades, so that the negative pressure area is formed in the upper and lower impeller cavities. At the same time, the slurry on the upper part of the cover plate is sucked into the upper impeller cavity through the circulation hole on the cover plate to form the slurry upper circulation. When the pulp is thrown out from the lower blade, the pulp from the lower part is added to the center, thus forming the lower circulation of pulp. The air is sucked into the upper impeller cavity through the suction pipe and central cylinder, and mixed with the inhaled slurry to form a large number of small bubbles, which are evenly dispersed in the tank after passing through the cover plate to form mineralized bubbles. The bubbles are blown up to the foam layer and scraped out by the scraper. The structure of SF flotation machine XCF aerated flotation machine is shown in the figure, which is composed of a tank containing pulp, a large isolation disk impeller with upper and lower blades, a pedestal stator with radial blades, a split disc cover plate, a split central cylinder, a connecting pipe with vent, a bearing body, a hollow spindle and an air control valve. There are two kinds of structure: open type and closed type. The bearing body has seat type and side hanging type, and is installed on the cross beam which is also used as the air supply pipe. XCF aerated flotation machine can be widely used in the separation of non-ferrous metals, ferrous metals and non-metallic minerals, and it is suitable for the roughing and scavenging operations of large and medium-sized flotation plants.

2. Under "add slide to Microsoft Word document", if you want to embed slide into word document, please click "paste"; If you want to link slides to a word document, click Paste link. If you link files, they will also be updated in the word document when you edit them in PowerPoint
3. Click OK. At this point, the system will create a new word document and the presentation to the document. If word is not started, the system will start word automatically
■ let PowerPoint Slide play automatically
to let PowerPoint Slide play automatically, you just need to right-click the document when playing, and then execute the "show" command in the pop-up menu, or change the extension of the file from PPT to PPS before opening the document, and then double-click it. In this way, we can avoid the inconvenience and tedious caused by opening this file first every time
■ add ppt's "regret medicine"
when using PowerPoint to edit a presentation, if the operation is wrong, just click the "undo" button in the toolbar to return to the state before the operation.

Next, just the inserted presentation object, change the pictures in it, and arrange the positions between them
■ quickly and flexibly change the color of pictures
making presentation courseware with PowerPoint and inserting beautiful clip art will add color to the courseware. But not all the clippings meet our requirements. The color matching of clippings is often unreasonable. At this time, we can right-click the clip and select the "show 'picture' Toolbar" option (if the Picture toolbar has been automatically displayed, this operation is unnecessary), and then click the "picture recolor" button on the "picture" toolbar to change the color of the picture in the subsequent dialog box
■ add company logo to PPT
when PowerPoint is used to make a presentation for the company, it's better to add company logo on the first page, so as to indirectly do free advertising for the company. Execute the "view master slide master" command. In the "slide master view", put the logo in the appropriate position. Close the master view and return to the normal view. You can see that the logo is added to each page, and you can't change it in the normal view
■ "save" special fonts
in order to get good results, people usually use some very beautiful fonts in the slides. However, when the slides are copied to the presentation site for playback, these fonts become ordinary fonts, and even the format becomes irregular e to the fonts, which seriously affects the presentation effect
in PowerPoint, execute "file - save as", click "tools" in the dialog box, select "Save option" in the drop-down menu, select "embed TrueType font" in the pop-up dialog box, then select "embed only used characters" or "embed all characters" as required, and finally click "OK" to save the file
open the control toolbox, click the "text box" option, insert the "text box" control, and then hold down the left mouse button in the slide editing area to drag out a text box, and adjust its position and size according to the layout. Then right click the mouse on the "text box" and select the "properties" command in the shortcut menu to pop up the "text box" property window. In the property window, set some properties of the text box
after setting, right-click the "text box" and select the "Edit" command in the "text box object" to input the text. After editing the text, click the mouse anywhere outside the text box to exit the editing status. A text box that allows the text in the box to move with the scroll bar is ready
rotate like this. In fact, we only need to select the inserted clip, and then click the "text wrapping" button in the "picture" toolbar. In the pop-up text wrapping mode, we can select any other wrapping mode except "embedded type", and the clip can rotate freely. In addition, if we first insert clip art in PowerPoint, and then cut it into word, we can also rotate it freely
if you want to hide the "eye" icon on the right side of the "shape", you can hide the "shape" that blocks the line of sight

to a slide in a presentation, first select the slide you want to from the outline or slide options in the normal view. If you want to select multiple slides in order, press shift when you click; To select slides out of order, press the CTRL key as you click. Then, on the Insert menu, click slide , or press Ctrl + Shift + D to the selected slide directly after the selected slide<

■ let the slide listen to me

You are full of pride and enthusiasm in the presentation or introction of a new proct, but accidentally e to the wrong operation of the left mouse button, the slide jumps to the position that should not appear, or you should press the left mouse button to switch to the next one, but a shortcut menu appears e to the right mouse button. Don't worry, just a little setup, you can get rid of all these annoying problems
open "slide switch" from the task pane, remove all the "when clicking" and "every" check items in the film change method section, and then apply this setting to all slides, and then switch to the next or previous one, which can only be operated through the direction keys on the keyboard. As for another problem, the solution is also very simple. From the "tools" menu, open the "options → view" window, and cancel the "right click shortcut menu" check box in the "slide show" section

5. Windows seems to have no lightning interface driver....
6. My system is win7. Every time I turn on the computer and connect to the Internet, there will be a 651 error. The indicator light of the telecom cable cat is very normal, but I can't connect to the Internet. The yellow exclamation mark is displayed in the lower right corner of the screen. Every time you have to unplug the network cable, wait for 5 minutes to re insert the network cable, the network will be normal. Sometimes, if you can't connect to the network after re inserting, you can call 10000 and ask the customer service to reactivate the account and password of the port, and it's normal. I don't know what's going on. I hope the experts can answer it
