1. Refer to section 3 and 8 of Chapter 6 of the design manual of the concentrator. The number you need is the maximum relative granularity Z. let me give you a brief table. For medium fragility ore,
cycle jawbone standard cone short head cone
excessive grain content β% 20 25 35 60
maximum relative particle size Z 1.45 1.60 1.90 2.2 ~ 2.7
you are right. But I'm tired by hand. Give me a point
it doesn't mean that the particle size of ore discharge is so large, it means the largest particle size, and the content of oversized particle is corresponding to the relative particle size. However, these data are in the early stage. Now the performance of the equipment has improved a lot. The specific data need to consult the equipment manufacturer.

the following is what I turn to you [in case I can't open the web page]:
some time ago, QQ era successfully updated the BIOS for its own TNT, and wrote a "TNT brain changing story" immediately, After this article was published in diyclub and DIY magazine, it won the attention of many friends. Many inexperienced friends who wanted to try wrote to ask how to update the BIOS of the video card in the QQ era, how to operate it, what are the advantages and disadvantages of updating the BIOS, and how to fix it if the BIOS of the video card is updated incorrectly, Originally, QQ era thought that in "TNT for brain" and you introced some methods of updating graphics card, but now it seems not very clear, so QQ era wrote this "graphics card BIOS Upgrade Complete Manual" to you, I hope it can help you< Can your graphics BIOS be updated
before updating the BIOS of your graphics card, the first thing you need to know is whether the BIOS used on your graphics card can be updated? This is obviously the main problem. If your graphics BIOS can't meet the requirement, you don't need to look down
the 28 pin al in-line BIOS chip, al mount BIOS chip and four pin mount BIOS chip are commonly used in the BIOS of graphics card. It is not easy to determine which can be updated and which can not be updated from the model of BIOS chip. How can we get this conclusion? That's the model of the BIOS chip
BIOS chips are basically divided into EPROM (erasable ROM), EEPROM (electrically erasable ROM) and flash ROM (fast refresh BIOS). Among these chips, EPROM is the most primitive, and its information is written through the BIOS writer. If you want to erase it, you need to irradiate the small window on the chip surface with ultraviolet light, and then write it again with the writer, The characteristics of this kind of bios are very obvious. There is a bright glass skylight on the surface of the chip (often pasted by adhesive tape). There is also a low-cost EPROM surface without this window. Its characteristic is to use the writer to write, and it can only be written once, and can not be erased. If it is written wrong, the chip will be scrapped. This kind of BIOS usually starts with 27c. If your graphics card uses this kind of BIOS, there is no chance to upgrade it
EEPROM is an electrically erasable BIOS. This kind of BIOS doesn't need to be written into the computer. It can be erased by giving it a 12V electrical signal, and then write it. When it drops back to 5V, it will work normally, which brings great convenience to the upgrade. However, because the BIOS voltage on the graphics card is not adjustable, it is also a trouble to update if it encounters this kind of BIOS, Most likely, it can't be written because it can't raise the voltage. The front of this kind of BIOS model is often 28c. It should be noted that some BIOS coded as 28F can write without increasing the voltage, which is very convenient. This kind of BIOS supports refresh
flash ROM is an evolutionary version of EEPROM. In addition to all the features of EEPROM, it also has a feature that it can refresh without hindrance and can be cleared and rewritten at any time. In front of this kind of BIOS models, 29c, 29e, 39E, 39L, 49e and many others are commonly used. At present, the popular video card procts use similar BIOS chips
to sum up, not every video card can update the BIOS, but it depends on whether the BIOS chip you use can support it. According to the experience of the QQ era, 9880, riva128, savage3d and the procts before these cards are relatively old on the market, generally unable to update BIOS. For savage4, TNT, tnt2 series, g400, rage128 and other mainstream procts, BIOS can be updated. Of course, QQ era also found that a large number of miscellaneous tnt2 graphics cards use non refreshing BIOS. If friends choose graphics cards, this point should be paid attention to
2. Can the refresh program recognize it
if your graphics BIOS can be refreshed, you can go to the second step. Whether the refresh program can recognize the BIOS type used by your graphics card is also very important, because if it does not recognize, the refresh work will not be able to proceed. Before refreshing, make sure that the refresh tool can support your graphics card BIOS, The tools and BIOS packages mentioned in this paper are used by NVIDIA Series graphics cards.)
we can use the refresh program of the graphics card to check whether it can support your BIOS. The operation method is to put the refresh program and BIOS package on the hard disk first, and then boot the system again. Before entering windows, press the F8 key and select safe mode and prompt only. At this time, the system will run to the C > prompt state
go to the disk and directory where you store the program (here you need some DOS commands. If you don't, there's no way, because if you talk about DOS commands now, I'm afraid you won't be able to talk about them for several days and nights!), Then execute nvflash C, here nvflash is the public version of NVIDIA refresh program, for many NVIDIA graphics cards are effective. Refer to figure 1. This is the TNT graphics card in QQ era. The refresh program can test the 29c BIOS of Winbond. If support ROM not found is displayed at this time, it proves that your graphics card BIOS cannot be refreshed or the refresh tool version is too old<
3. Looking for a new BIOS on the Internet:
after the above conditions are met, we can go to look for BIOS. There are two intentions to update the BIOS of the graphics card. One is to use the BIOS of the famous factory to update the graphics card of the famous factory to improve the stability and compatibility, and the other is to use the BIOS of the famous factory to replace the graphics card of the non famous factory to improve the performance and function. No matter which choice, QQ era should remind you that the conditions of the card and BIOS should be the same, such as the chip type of the graphics card, the form of the video memory (SDRAM or SGRAM), the capacity of the video memory, whether there are other functions on the card, such as video output and acquisition, etc., so as to prevent the display card from working
the best place to find a new BIOS on the Internet is, of course, to go to the major well-known graphics card manufacturers. Big companies like Rita and Elsa can find links to these sites from the home page of QQ era, and then you can check the relevant graphics card BIOS
in addition, the famous home of drivers in China is also a treasure land, where you can provide many BIOS of graphics cards for you to download. It is not only fast and language barrier free, but also valuable that you can find many brands of BIOS in one station, which is very convenient
if you are using TNT graphics card, you don't have to go around. There is a TNT BIOS package in the secret base of QQ era, which contains three refresh tools and more than ten BIOS packages of TNT graphics card, which is enough< How to use the refresh tool
after downloading BIOS and refresh tools, how to use these tools to refresh the BIOS of graphics card? We might as well study the function of nvflash to see what's wonderful
referring to the figure below, we can see all the functions provided by nvflash<
in the QQ era, I'll explain to you one by one:
nvflash BIOS package name refreshes BIOS to the chip
nvflash e clears the contents of BIOS
nvflash D displays the header contents of BIOS
nvflash C detects whether BIOS can support refresh
nvflash w adds write protection to BIOS
nvflash r removes write protection from BIOS
nvflash f detects the hardware devices that can be supported
nvflash SH Help information
among these functions, refresh is our next step, so let's not talk about it first
nvflash e is to clear the contents of BIOS, but because it is automatically cleared before refreshing BIOS, this function is not very useful
nvflash D should have provided the function of backing up the BIOS of the graphics card, but unfortunately, it can only display the contents on the screen. If you want to back up the graphics card, you can download special tools from my secret base
the function of nvflash C mentioned in the previous step
the function of nvflash w / R is to add or open a protection lock to the BIOS to prevent random erasure in other environments. However, because this function has no password restriction, and there is no virus attacking the BIOS of the graphics card at present, it is not very effective
nvflash f is a hardware device that can be used to detect and support. Because this refresh program can support many kinds of NVIDIA graphics cards, it can be used to detect the types of graphics cards< br /> There is no need to say more about the help information, that is, the function of displaying these tips< 5. Come on! Brush it
seeing this, I think the basic knowledge in your mind is almost there. Let's do it now
first, restart the system and enter the DOS real mode environment, because the refresh tool of the graphics card is not suitable for windows, so as to prevent the interference of other programs (some graphics cards of ASUS and imperial alliance can be refreshed in windows!)
before entering windows, press the F8 key and select item 6 safe mode and prompt only to enter the DOS state
go to the disk and directory where the program is stored. If you are sure that the refresh tool and BIOS package you are using are correct, you can directly enter the name of the refresh tool and the BIOS instruction package, and press enter. The refresh tool will automatically proceed, as shown in the figure below
because the BIOS capacity of the graphics card is very small, generally 32K or 64K, the refresh process is very fast, that is, about 1 or 2 seconds. Because the graphics card needs to be cleared when it is refreshed, the graphics card will stop output display ring this period, so there will be a short black screen
after the black screen is over, the graphics card will restore the display, and provide some information after refresh, which can help you understand the refresh process. See the figure below< 6. What if the graphics card is damaged
BIOS is the "headquarters" closely related to all kinds of hardware devices. If BIOS is damaged, it's like losing the leader's army. Of course, there are not many people working hard. If BIOS refresh error occurs in graphics card, it will lead to black screen, unable to start, splash screen and other phenomena. If this happens, what should we do
compared with the motherboard, the consequences of BIOS refresh error are much lighter, because if the motherboard doesn't work, any other devices can't work, and if the graphics card is damaged, it just doesn't work. If you want to restore the original BIOS of the graphics card, you need to use the al graphics card to boot the machine, So the first requirement is that you need a PCI slot type graphics card
if you find a PCI type graphics card, first pull down the AGP card (because it doesn't work), then plug in the PCI graphics card, boot it up, and enter the BIOS settings (note that the main board BIOS, don't say the graphics card BIOS is dizzy!)
select the intergrated peripherals option, find the init display first function after entering, then change the following settings to PCI, save the BIOS settings and shut down the machine
plug in the AGP card again at this time, but note that the display is still connected to the PCI graphics card, restart. Because today's motherboards support al graphics card (AGP / PCI) work, there is no need to worry about it
