Chapter 219 (2/2)

”Hello! What can I do for you? ” Shen Qingshan asked strangely.

”Well, we want to set up a cement plant in our hometown, but we don't know how to produce cement, what specific process and what machinery and equipment we want, so we want to ask Mr. Shen for advice.” Guo Xiang said.

”To run a cement plant?” Shen Qingshan was surprised, ”is it the local government? Or which unit? ”

”No, it's our personal business.” Guo Xiang smiled.

”Private?” Shen Qingshan stared. ”Do you know how much it costs to run a cement plant?”

”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 took a breath, so much? It's astronomical. I can't earn it in my life. Big brother and sister-in-law can't have so much money, can they?

”A million?” Guo Xiang nodded and meditated. There is a lot of money. Now the money is worth tens of millions of later generations.

If it was before, she couldn't help it, but now Gu Zhennan has it there. Don't worry.

One million is only more than 100000 US dollars at the black market price, but almost half at the national foreign exchange rate. How can we maximize the value of US dollars?

But now let's not consider this. Let's listen to Mr. Shen talk about running a factory.

”If we want to run a small cement plant first, will it be less?” Guo Xiang asked.

”I'm not talking about a big one. I can't get a big one million, but it's not impossible to be a little smaller. But don't mistakenly think that just a few pulverizers are OK. The process of cement is not so simple. ”

”Sometimes we see a lot of stones piled on the mountain or on the roadside. There are conveyor belts and several hoppers. We think that is the production of cement. In fact, it is only a part of raw materials. There are large calcination equipment to be produced. It is not so simple.” Shen Qingshan said.

”Do you have raw materials? That's why I have this idea? ” Shen Qingshan looked at them. ”If you just provide raw materials for the cement plant, it's simple. Tens of thousands of yuan can be done. If you want to produce cement completely, it's not easy.”

”Can Mr. Shen tell us about the specific production process? We are interested in setting up a cement plant. ” Guo Xiang said.

It is not impossible to simply provide raw materials, but raw materials are not worth money. What is worth is finished products. Of course, we should grasp the maximum profit in our own hands.

”OK!” Seeing that Guo Xiang was still modest, Shen Qingshan took out a book and a pen and told them in detail, ”you see, this is the raw stone on the mountain, usually limestone. Break these large pieces of limestone and transport them to the material plant. Put limestone, clay and iron ore into the crusher respectively, and put them in the material yard for pre homogenization and storage. This is the first step. ”

”The second step is to send the raw materials to the cement plant, mix the raw materials according to a certain proportion, grind them in this raw material machine, enter the homogenization warehouse for homogenization, and prepare them into raw materials with uniform composition.” Shen Qingshan pointed to the flow chart in the book.

Guo Xiang nodded as he looked.

Shen Qingshan pointed to the equipment behind, ”the third step is to heat and calcine the mixed raw meal in the preheater and calciner to complete the chemical reactions such as limestone decomposition. The fourth step is to enter the rotary kiln for further decomposition and solid-phase reaction, and complete the sintering of clinker in the kiln to form cement clinker. ”

”Step 5: the clinker from the kiln is cooled by the grate cooler, crushed and then enters the clinker warehouse. The sixth step is to feed clinker and gypsum into the cement mill in proportion, grind them into qualified cement, and finally pack them, which is the finished cement. ”

Guo Xiang nodded. It turned out to be quite complicated. In some previous lives, he saw the same thing with several hoppers in the quarry and thought it was producing cement. It turned out that it was just crushing materials, and the complex process was still behind.

Moreover, these are relatively large equipment. No wonder teacher Shen said he wanted a million. It seems that it is really necessary.
