MB miner

1. Well, I use it. Ws880 is better. It can switch 5GHz band. The connection speed is 300MB. It's very good to avoid 2. 4GHz router interference. At the same time, there are 2. 4G bands to choose from. Moreover, the speed of wired connection port can reach 1GB. It's an absolute leverage. The speed of wired router is 100MB and that of wireless is 54Mb

2. At present, most of the mainstream Ethereum mining machines in the market come from bitmainland and Jianan Yun. However, with the decline of Ethereum's price, the profits brought by mining have been very meager. Investors can choose to invest in Ethereum on the digital currency exchange. At present, the mainstream digital currency transactions in the market are all coin security, fire coin network, bitnet, etc.

3. Do you want to go to the West Lake Cultural Square or the West Lake
if you go to the West Lake Cultural Square (not beside the West Lake), take subway line 1 to Xianghu. Get off at the West Lake Cultural Square Station and you'll be there
if you go to the West Lake, you can take the subway line 1 in the direction of Xianghu and get off at longxiangqiao station.

4. If you use NVIDIA graphics card, you can directly use CUDA mode in guiminer. If it's amd graphics card, you need to download AMD's own stream SDK package for OpenCL, about 200MB, which can be downloaded from AMD's official website. For general users, the server can select btcguild (any). Fill in the user name and password of your worker account registered on btcguild website, and then click "start mining", and the next thing will be left to GPU.

5. It mainly depends on the use of Xunlei. If the total download speed is close to 10MB / s, there will be no problem with the network. That is to say, the total downlink speed of all devices is 12MB / s

6.

The official definition of ball mill model and specification is a series of indicators reflecting the nature, performance and quality of the proct, which is generally composed of a series of letters and numbers with a certain number. For example, brand name, grade, composition, content, purity, size, etc. In short, specification refers to the size of performance indicators, and model refers to the name (or code) obtained from the collection of specifications and models

ball mill specification: if it is expressed by the diameter and length of the ball mill cylinder, it can be shown as φ two point two × 7m、 φ two point four × 13m、 φ three × 11 m, etc

ball mill model: also, according to the diameter and length of the ball mill cylinder, it is mqgg 1212, mqG 1212, mqy 1212, mqyg 1212, etc., in which the letter part indicates the abbreviation of the ball mill equipment, and the number part indicates the diameter of the ball mill cylinder. Take mqgg 1212 as an example: this model is a wet energy-saving lattice ball mill φ one point two × 1.2m

generally, there are many models and specifications of mine ball mills, which can be divided into large, medium and small types according to the level. Taking ferrous metals as an example, a large concentrator with a daily processing capacity of 3000t, a medium concentrator with a daily processing capacity of 900-3000t, and a small concentrator with a daily processing capacity below 900t

the commonly used mining ball mill equipment mainly includes

wet energy-saving lattice ball mill. This lattice ball mill mostly deals with coarse minerals and adopts large double row self-aligning roller bearing, which effectively reces the friction force and is easy to start. Compared with other ball mills, it can save 20-30% energy

small ball mills are mainly used in small and medium-sized development enterprises. The proction scale of such enterprises is small, and the investment cost of small ball mills is low, so the investment income of users is fast, and it will not cause a waste of resources. The main ball mill equipment and model parameters suitable for medium-sized concentrator are as follows:

the above introces the definition of mining ball mill model and specification, and the distinction of model and specification according to large, medium and small type selection, and shows the model, specification and parameters of ball mill according to each level, which can be used for reference. However, in the actual concentrator, the specific model and specification of ball mill selected by each concentrator should consider the nature of materials and beneficiation conditions. It is recommended to select qualified ball mill manufacturer for test selection< br />

7. If I were an inventor, I would invent an umbrella. There are many small buttons on the handle of the umbrella. Just press the white button, the umbrella will send out beautiful music to accompany you home. In summer, it's very hot outside, and no one wants to go out. You can take this umbrella with you. Press the black button, and there will be a cold wind under the umbrella. It's very cool

If I am an inventor, I want to invent a schoolbag. There are many buttons in the schoolbag. As long as you press the button with light words, even if you put more things in the schoolbag, you will not feel heavy. If you want to listen to music, as long as you press the button with music words, the schoolbag will send out beautiful music. If you want an umbrella, You can click the button with the image of an umbrella, and an umbrella will appear on the schoolbag, so that you won't get wet from the rain and catch cold

If I were an inventor, I would invent a car with a pair of invisible wings. If there are too many cars on the road, you can press the button in the middle of the steering wheel, the invisible wings will pop out, and you can drive in the air! If you are in a hurry, there is a white button on the seat. Once you press the button to get off the car, it will become like a rocket. It will arrive in a short time, and the car has the function of getting bigger and smaller.

8. It's better to use gtx650 than GTX 460 768mb. The performance is better and the price is almost the same. It's suggested to buy a new one if you want to use a card, because the second-hand ones are usually removed from the miner!
