2. Guide: ball mill is a very common grinding and mining equipment. Its grinding principle is to use the friction between the material and the steel ball or steel column and the rotation form of the rotating drum to make the material reach the ideal particle size standard, so as to facilitate the classification and flotation operation in the subsequent beneficiation process. Small series for you to introce the ball mill, then, as a central part of the ball mill grinding operation, whether there must be emphasis on the operation method? Here, Hongxing Machinery believes that as long as we master the nine word secret of high concentration, large return sand and uniform feeding, we can achieve the most ideal grinding effect. It will be described in detail below. The so-called high concentration mainly refers to the mass fraction (pulp mass fraction), which is the percentage of ore mass (dry weight) and total pulp mass (ore + water) in the pulp. Here, the mass fraction refers to the pulp mass fraction (grinding mass fraction) in the grinding machine. Grinding mass fraction is an important factor that affects the proctivity of grinding machine. It determines the friction between grinding medium and ground material, pulp fluidity and effective density (density difference between medium and pulp). In the operation of the grinding machine, a higher grinding mass fraction is generally used, so that a layer of slurry can be attached to the surface of the medium, so as to enhance the grinding effect beneficial to the grinding. At the same time, there is a large amount of ore per unit volume in ore discharge, so the ore discharge is large. However, if the pulp mass fraction is too high, e to the increase of pulp density, the effective density, activity ability and striking effect of grinding medium will be weakened. At the same time, e to the high mass fraction, high viscosity, poor fluidity and rection of total ore discharge, the proctivity of grinding machine will be reced and even swelling will occur. Therefore, high concentration means to increase the grinding mass fraction within a certain range, which is concive to improving the grinding effect. On the other hand, we need to realize large sand return in the process of ball mill operation. In order to explain such advantages, first of all, let's talk about what is sand returning. Return sand refers to the coarse-grained fraction returned by the classifier to the grinder for regrinding ring closed-circuit grinding. The amount of return ore is often several times of the original ore feeding. The ratio of return sand quantity to raw ore feeding quantity is called return sand ratio. Practice has proved that the return sand ratio will directly affect the proctivity of the mill. The larger return sand ratio increases the total feeding capacity of the mill, thus increasing the discharge speed of the mill, shortening the residence time of materials in the mill and speeding up the circulation. In addition, although the returned sand is coarse-grained ore, it is finer than the raw ore after all, so the total feed particle size composition of the mill becomes finer, and the comprehensive results are concive to improving the proctivity of the mill. The relationship between the return sand ratio and the relative proctivity of the mill was studied. It can be known that within a certain range (such as between 100% and 500%), with the increase of the return sand ratio, the proctivity of the mill will increase. When it reaches a certain value, the proctivity increase is very small, and the total feeding capacity of the mill is close to the maximum throughput, which is easy to cause ball mill swelling. Therefore, the sand return ratio should be kept stable and close to a constant value. Finally, in the process of ball mill grinding operation, we should also pay attention to the situation is the average feeding. Why do you say that? In fact, there are two main implications: one is that the feeding speed (ore quantity fed into the mill per unit time) is constant; The second is that the particle size composition of ore feed is uniform. In order to improve the grinding efficiency, the ore feed should be continuous, uniform and stable at a high level. More time and less time will make the mass fraction in the mill fluctuate frequently, which is not concive to the grinding process. Particle size segregation of grinding feed often occurs in the silo, the middle is fine, and the surrounding is coarse, which is easy to cause uneven feed composition. If the operation can not be adjusted in time according to the particle size, swelling will occur. Therefore, multi-point discharging and feeding should be adopted as far as possible. As long as you master the above ball mill operation specifications, or the experience and lessons learned by predecessors through personal practice, you can make the ball mill work in the best working condition all the time. The core problem revealed by the nine word secret is the balance of input and output efficiency.

5. If you forget the lock password of the mobile phone screen, you can't unlock the screen. It is recommended that you try the following operation:
1. If you set the pattern / signature / fingerprint unlocking mode, you can use the pin code set when drawing the pattern / signature or entering the fingerprint to unlock
1) pattern / signature unlocking: when the incorrect unlocking pattern / signature is entered for many times (generally five times), a "backup pin" (forget the password) will be prompted in the lower right corner of the screen. Enter the previously set pin password and click OK
2) fingerprint unlocking: when the fingerprint cannot be unlocked, a "backup pin" will be prompted at the bottom of the screen. Enter the previously set pin password and click OK
2. If your mobile phone supports the remote control function of Samsung die and meets the following conditions: remote control and mobile data (or WLAN) have been turned on; If the mobile phone has been bound with a Samsung account, please log in to the remote control website
after logging in with a Samsung account, click "unlock my device". After operating in this way, the previously set lock screen mode will be directly changed to the default slide unlock mode, and then slide the mobile phone to unlock
if the above operation is invalid or the "unlock my device" function cannot be used because it does not meet the requirements of remote control function, please send the machine to Samsung Service Center for after-sales engineer to help you unlock safely.

6. How to deal with the forgotten lock screen password:
case 1: forget the lock screen password, but you can use your fingerprint or face to unlock the mobile phone
1. Input the wrong lock screen password five times in a row in the password input interface, and then click the "forgotten password" on the screen after "the mobile phone is locked" pops up, At least 4 points are required for 5 wrong passwords, and the passwords entered each time are different)
note: if you use FBE encryption technology, you need to go to vivo customer service center to unlock it
2. Click forget password and use security to modify the lock screen password
note: the lock screen password can be modified only when both security keys are entered correctly
3. Before mobile phone version 4.1: if the security guard forgets to enter the cloud service, after starting the mobile phone search, enter the mobile phone settings system management / more settings backup and reset / restore factory settings clear all data immediately clear enter the password of vivo account to clear the data, clear the data after decryption, Re enter the mobile phone to set the lock screen password
find the mobile phone version 4.1 and later: even if the clear data command is executed, after entering the mobile phone, you still need to enter the password of the account
case 2: if you forget the lock screen password, you can't unlock the phone with fingerprint or face.
1. Input the wrong lock screen password five times in a row in the password input interface (if you set the pattern password, the wrong password five times needs at least four points, and each time the password is different)
2. After "the phone is locked" pops up, you can click "forget password" on the screen, Enter the password to modify the lock screen
note: some models using FBE encryption technology do not have the option of "forget password" and do not support the use of security problem to verify and unlock. You need to contact the staff of customer service center to unlock
note: if you forget the lock screen password, you can bring your ID card and purchase invoice to the customer service center for unlocking Go to vivo official website / vivo mall app -- my -- website query or vivo official website webpage -- bottom down -- service support -- service website query -- select provinces and cities to query customer service center address.)
note: if you can't retrieve the lock screen password through the security, you can send the clear data command through the search mobile phone (all mobile phone data will be deleted). If the search mobile phone function is not turned on, it is recommended to go to the customer service center for processing
if you forget the password of vivo account, you can go to vivo official website / vivo mall app - my online customer service or the webpage of vivo official website - slide to the bottom - online customer service input manual customer service to enter the consultation and appeal.

Forget the student mode password and security problem at the same time:

< UL >

if you forget the student mode password and security problem at the same time, you need to restore the factory settings of your mobile phone to remove the student mode. Please back up the relevant data before restoring the factory settings

In

student mode, you cannot set & gt; System & gt; Backup and restore the factory settings in backup and restore. It is recommended that you enter settings & gt; Users and accounts & gt; Cloud services / cloud space & gt; In cloud backup, click backup now for data backup. You can also download hisuite from your computer and connect to your mobile phone for backup

after the backup, please restore the phone to the factory settings and remove the student mode

forcibly restore the factory settings: when the mobile phone is not connected to the USB data cable, press and hold the power key and volume up key at the same time when it is turned off, release the power key when the power on screen appears, release the volume up key after 3 seconds to enter the recovery mode, and select "restore factory settings" in the recovery interface

note:

forcing the factory settings to be restored can remove the student mode, but all personal data in the mobile phone will be lost.
