Zhang Yi's face darkened after hearing this, he didn't understand everything, Liu Rui said this, the technical weight of what Zhang Yi just said was lowered, isn't this a black trick for him.

Zhang Yi also ignored Liu Rui, but said to Director Yang: "Selective grinding is a grinding technology used for the microscopic mineralogy principles just mentioned, and the purpose is to better strip the gangue minerals. ”

"This requires a scientific match of the ratio of large and small balls in the ball mill, as well as the number of balls, materials, and the application of grinding aids, which must be matched according to the specific mineral properties."

Hearing this, Director Yang has confirmed that Zhang Yi has a way, but he doesn't know what indicators he can get, but as long as Zhang Yi can handle it, it's good, this is a lifesaver for him, how can there be a reason not to grasp it.

Director Yang said with an excited expression on his face: "Brother, I can't tell you for a while, can you come with me to the company tomorrow, I have complete information and equipment, let's verify it and make it if we can't do it." ”

Zhang Yixin said, you are just improving the grade, selective grinding 98 years is indeed not widely used enough, and the theory is not mature enough.

However, 19 years later, the technology has made a huge breakthrough, and internationally renowned experts have derived the mathematical function equation of selective grinding, and the first technology that comes to mind in improving the concentrate grade of each large mining industry is selective grinding.

The problem that Director Yang wants to solve this should not be a big problem, but the purpose of his visit this time is to help the laboratory get 1 ton of wolframite.

And he doesn't have much time, it's only 5 days when it's full, and if he is conservative, he just leaves himself 3 days.

If you want to be busy with wolframite tomorrow, you naturally can't take care of Director Yang.

Zhang Yi hesitated for a moment, and said with some embarrassment: "Director Yang, I can't hide it, the purpose of my visit to Persimmon Bamboo Garden this time is to negotiate the purchase of wolframite. ”

Director Yang looked at Wei Ming with some doubts, he didn't know in advance that what Zhang Yi was going to buy was wolframite, and thought that it was just ordinary ore, which were ready-made, and it would be good to go directly to the mine and pull them away.

Wei Ming nodded and said: "That's true, Brother Zhang is here to buy wolframite, and he has communicated with me to buy wolframite from Chenzhou Mining." ”

"Chenzhou Mining? Haha, this one is easy to do. Director Yang suddenly laughed and said loudly: "Brother Zhang, don't worry, Boss Chen, I know you very well, I'll give you something about this, just wrap it up on me." ”

Wei Ming also knows that Director Yang has a wide range of contacts, and a company as big as Weide Mining can be the director of the technology center, but it is not possible to have a few brushes.

Besides, many bosses in Persimmon Bamboo Garden have low diplomas, many of them who graduated from primary school and made a fortune by opening mines, and there is no decent technician in the factory, and many of them hire technicians from other mining companies with high salaries to give them on-site guidance.

Director Yang is a well-known technical expert in Persimmon Bamboo Garden, and he is often a guest of honor of major mine owners, and his popularity is not low.

Since Director Yang is willing to help, it can't be better, Wei Ming said with a smile: "Brother Zhang, you have become more than half of the matter now, Director Yang is a person with hands and eyes, since he has spoken, then you just wait to lift the mine." ”

"Where did Lao Wei say, why did I have my hands and eyes to the sky, you have to be punished for drinking." Director Yang pretended to be angry and said, they are all from the villagers, Director Yang lives not far from the next door, they often meet, and they are quite familiar with each other, Wei Ming also knows that Director Yang is not simple, so he often invites Director Yang to come over for a few drinks.

"Okay, I'll admit the punishment." Wei Ming sneered, and after speaking, he picked up the wine glass in front of him and took a sip.

didn't care that Wei Ming just took a sip, Director Yang turned his head to Zhang Yi and asked, "What's the matter, has my brother thought about it?" It's easy to say what the conditions are. ”

"Look at what my brother said, what conditions are needed, I'll just go over and take a look." Zhang Yi said with a smile, everything has been said about this, and it would be hypocritical not to agree.

And he didn't expect this technology to make money or anything, as long as Director Yang helped him get 1 ton of wolframite, then the task was completed.

Besides, if he helped Director Yang to deal with the concentrate grade and helped him so much, then Director Yang would have to owe him a favor, and it would be much easier to do things in Persimmon Bamboo Garden in the future.

Hearing Zhang Yi's promise, Director Yang happily picked up his wine glass and said, "Okay, then it will be more troublesome for Brother Zhang, come, I'll give Brother a glass." ”

Director Yang bumped into Zhang Yi, this clinking glasses was different from the clinking glasses he had just come in to meet.

At that time, Zhang Yi was just a young man who came to buy mines, and he had nothing to do with him, but now Zhang Yi has become his savior, and his status in his heart is obviously different.

"Director Yang is polite." Zhang Yi also respectfully touched the glass, and then drank it all.

"Okay, let's move our chopsticks and keep drinking." Wei Ming saw that things were almost over, and beckoned everyone to start eating again.

Song Lin and the others have been listening to it for a long time, Zhang Yi and they are talking about some technical things, and they can't understand it, and besides, their leaders are present, and they don't dare to interject indiscriminately, so they have to listen quietly on the side.

The next dinner was also very happy, and Director Yang had a solution to the technical problems that had plagued him for a month, and this solution was provided by Zhang Yi, so he naturally had to accompany Zhang Yi well.

Zhang Yi wants to buy a large amount of wolframite with Wei Ming, which is his big financier, and on his territory, he must let Zhang Yi enjoy himself.

Everyone had a purpose, and the next scene of this meal was much more harmonious, and before they knew it, Zhang Yi and Liu Rui were almost drunk.

In order not to get drunk, Zhang Yi has to pay attention to it in an unfamiliar place, so he always runs to the toilet when he drinks, and spits out the wine from time to time.

I don't know how Liu Rui got back to the room.

......

Early the next morning, an old Santana was parked in front of the Tianshui office building.

Director Yang kept wandering around the first floor, and asked Song Lin next to him from time to time: "Little Song, has Brother Zhang gotten up?" ”

The time was set at 9 o'clock, and it was only 7 o'clock at this time, and Director Yang was not good to go upstairs to disturb Zhang Yi's rest, after all, he drank a lot of wine last night, and it was normal to get up late.

Song Lin couldn't help it, he ran upstairs to look at it several times, and finally shook his head when he went downstairs.

Zhang Yi slept very deeply this night, he hadn't drunk like this for a long time, although he was not drunk, but he was also dizzy.

Looking at Liu Rui, who was still sleeping not far away, Zhang Yi shook his head, this guy really doesn't regard himself as an outsider, and he sleeps so deeply in a strange place.

After getting up and washing up briefly, Zhang Yi went downstairs and happened to see Director Yang waiting anxiously on the first floor.

Seeing Zhang Yi go downstairs, Director Yang said in surprise: "Brother Zhang finally got up, did he sleep well last night?" ”
