Guo Xiang and Gu Zhendong turned their heads at the same time and found a girl with a round face standing behind them.

The girl has a white shirt on her upper body and a blue skirt on her lower body, although she is not particularly beautiful, but because she is young, her face is full of collagen, her eyes are big, her eyelashes are very long, flickering, and she is very cute.

"Hello classmates, do you know that there is a teacher? We asked a teacher who specializes in silicates to ask a little question. Guo Xiang said.

"I know, I'm a sophomore majoring in silicate, and my dad is my teacher." The girl said with a smile.

"That's great!" Guo Xiang's eyes lit up and he stretched out his hand, "Hello, my name is Guo Xiang, this is my brother Gu Zhendong, can we ask your father some questions?" ”

"Yes!" The girl stretched out her hand generously, "My name is Shen Meng, budding Meng." ”

Shen Meng and Guo Xiang shook hands and stretched out their hands to Gu Zhendong, looking at him, "Hello! ”

Gu Zhendong's face turned red all of a sudden, and he stretched out his hand embarrassedly, "You...... Okay, I'm Gu Zhendong! ”

"Let's go, I'll take you inside!" Shen Meng smiled, "My family lives in the school's faculty dormitory, and my dad should be at home." ”

"Do you have any questions for me first? I'm also a major, so I might be able to help you. Shen Meng said with a smile.

"Uh......" Guo Xiang didn't know where to start for a while, mainly because he didn't know what to ask, because he didn't understand anything.

"In terms of the whole process of cement production, raw materials, ingredients, machinery and equipment, all ......," Guo Xiang said.

Shen Meng looked at her in surprise, "To know so much?" Could it be that you want to build a cement factory? ”

Don't tell, girl, you are the truth! Guo Xiang nodded secretly.

"Impossible, right?" Shen Meng looked at Gu Zhendong again, and his face became redder and redder.

At this time, it is almost impossible to set up a cement factory by yourself, who has so much money?

"That's the idea." Guo Xiang smiled, "But we don't know anything, so we have to come to the school to ask the teacher." ”

"Then how did you come up with the idea of a cement factory? Collective enterprise? What county are you from? Shen Meng asked.

"This ...... Let's talk about it when we see your father. Guo Xiang said, otherwise he would have to say it again later.

"That's fine!" Shen Meng nodded, and looked at the two of them curiously, because they were the first to come to the school to ask for advice when they wanted to set up a factory.

When they arrived at the faculty dormitory, Shen Meng took the two to his house, opened the door, and a middle-aged man's voice came from inside, "Mengmeng is back?" ”

"Hey! Dad, there are guests. Shen Meng said.

"Who?" Shen Meng's father, Shen Qingshan, walked out, and when he saw that Guo Xiang and Gu Zhennan didn't know each other, he couldn't help asking, "...... are you?"

"Hello Mr. Shen!" Guo Xiang hurriedly stepped forward, "We are from Nanxian County, my name is Guo Xiang, this is my lover's younger brother Gu Zhendong!" ”

"Hello Mr. Shen!" Gu Zhendong also hurriedly stepped forward to say hello.

"Hello! What are you looking for from me? Shen Qingshan asked strangely.

"That's right, we want to set up a cement factory in our hometown, but we don't know how to produce cement, what the specific process is, and what machinery and equipment are needed, so we want to ask Mr. Shen for advice." Guo Xiang said.

"You want to build a cement factory?" Shen Qingshan was surprised, "Is it the local government that wants to do it?" Or which unit? ”

"No, it's our private business." Guo Xiang said with a smile.

"Private?" Shen Qingshan's eyes widened, "Do you know how much it costs to run a cement factory?" ”

"I just don't know, that's why I came to ask Mr. Shen about you." Guo Xiang said.

"At least a million!" Shen Qingshan stretched out a finger.

"Hiss~" Gu Zhendong gasped, so much? It's just astronomical, and I can't earn it in a few lifetimes. The eldest brother and sister-in-law can't have so much money, right?

"A million?" Guo Xiang nodded and pondered, there is a lot of money, and the money is worth now, which is equivalent to tens of millions in future generations.

If it was before, she couldn't help it, but now Gu Zhennan has it, she doesn't have to worry about it.

One million is only a few hundred thousand dollars according to the black market price, but it can be almost half more than half according to the foreign exchange rate of the country, how can we maximize the value of the dollar?

But don't think about this now, and listen to Mr. Shen talk about running a factory.

"If we want to start a small cement plant, will it be less?" Guo Xiang asked.

"I'm not talking about a big one, and you can't take a million big ones, but it's not impossible to be smaller. But don't make the mistake of thinking that just a few crushers are enough, the cement process is not so simple. ”

"Sometimes we see some mountains or roadsides, and we see a lot of rocks, conveyor belts, and a few hoppers, so we think that is the production of cement, but in fact, it is only a part of the raw materials, and there is a large calcination equipment to really produce it, which is not so simple." Shen Qingshan said.

"Do you have any ingredients? That's why you had this idea? Shen Qingshan looked at the two, "If you just provide raw materials for the cement factory, it is simple, tens of thousands of yuan can be done, if you want to produce cement completely, it will not be easy." ”

"Then Mr. Shen, can you tell us about the specific production process? We are interested in setting up a cement plant. Guo Xiang said.

If you simply provide raw materials, it is not impossible, but raw materials are not valuable, the value is still the finished product, of course, you must grasp the maximum profit in your own hands.

"Okay!" Shen Qingshan saw that Guo Xiang was quite modest, took out a book, and took out a pen to tell them in detail, "You see, this is the rough stone on the mountain, generally limestone, break these large pieces of limestone and transport them to the material factory, put the limestone, clay, iron ore, etc. into the crusher to crush, and put them in the material yard on the spot for pre-homogenization and storage. This is the first step. ”

"The second step is to send the raw materials to the cement plant, and the raw materials are matched in a certain proportion, placed in this raw meal machine and ground finely, and then homogenized into the homogenization warehouse and blended into a raw meal with uniform composition." Shen Qingshan pointed to the flow chart in the book and said.

Guo Xiang nodded while watching.

Shen Qingshan pointed to the equipment behind him, "In the third step, the mixed raw meal is heated and calcined in the preheater and decomposition furnace to complete the chemical reaction such as limestone decomposition. In the fourth step, enter the rotary kiln to further decompose and react with solid phase, and complete the firing of clinker in the kiln to form cement clinker. ”

"In the fifth step, the clinker out of the kiln is cooled and cooled by the grate cooler, and then enters the clinker warehouse after crushing. In the sixth step, the clinker and gypsum are sent to the cement mill in proportion to grind into cement that meets the requirements, and finally packaged, which is the finished cement product. ”

Guo Xiang nodded, it turned out to be quite complicated, in his previous life, he saw the same thing that there were several hoppers in the ore yard in some places, thinking that it was producing cement, but it turned out that it was just crushing materials, and the complex process was still to come.

And the latter are relatively large equipment, no wonder Mr. Shen said that it costs one million, it seems that it is really indispensable.
