CNC roughing machine

2. Caiyunbit's original creation is endless

unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<

first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:

Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer

3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

3. Install and run

after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts

2. After the driver is installed, you can see the new things in the device manager

3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer

4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter

5, run batch processing, and start to display mining data, about 300m, which is basically normal.

4. How to judge in time that the ball mill will have "bulging belly" in the grinding process, the imbalance of the material in and out of the mill, the "bulging belly" is not a sudden occurrence, but a process of occurrence, development and deterioration, and in this process accompanied by various abnormal phenomena, we should strengthen the sense of responsibility, timely find out and adjust accordingly, Eliminate "bloating" in slight stage. It can be judged from the following phenomena:
1) observe the current. In normal operation, the pointer of the ammeter which shows the current of the main motor always swings in a small range, indicating that the current changes very little. Once "belly bulge" occurs, e to the increase of material quantity in the mill, the effective space is occupied by a large number of materials, so the active range of the medium is small, the active power used to lift the medium is reced, and the center of gravity of the mill load (medium and ore) is increased, that is, the distance away from the center of the mill is reced, the resistance moment caused by eccentricity is reced, and the power required to overcome the resistance moment is reced, If the total energy consumption of the mill is reced, the current reading reflected by the ammeter will be reced. The more serious the bulging is, the more the current drops. When the grinding machine is bulging, it will drop to the lowest point. Therefore, once the operator finds that the current is graally decreasing, it should be adjusted in time to prevent accidents
2) listen to the voice. When the mill works, the sound mainly comes from the impact between the transmission mechanism itself and the medium ore liner plate in the cylinder. The intensity of the impact sound in the cylinder varies with the amount of material in the mill. When out of balance, the mill will be filled with high mass fraction slurry, the impact of medium on ore and liner will be weakened by viscous slurry, and the sound will be graally ll. In case of serious "belly swelling", the sound in the cylinder will almost disappear, and only the buzzing sound from other aspects can be heard. Therefore, from the change of sound intensity when the mill is working, it can be found that the mill is bulging
3) measure the score and observe the ore discharge. The mass fraction and discharge volume of the normal working mill should be basically stable, but when the belly bulges, the mass fraction begins to increase, the discharge volume is also large, the particle size becomes coarse, and "front spitting" and "back pulling" appear. In serious cases, e to the large mass fraction, the poor fluidity will not be discharged, and the discharge will stop when the ore is completely "inflated". Therefore, swelling can also be found from the changes of mass fraction, particle size and discharge of the mill
