After the porcelain basin became fine, I was sent to the wild to do infrastructure construction

The return of the elite combat team did not bring much impact to Baiyun Village. After the villagers were happy, they continued to devote themselves to the busy spring planting.

After all, this is a major event in the village, and it is also related to everyone's rations in the second half of the year. Not to mention the villagers, even the members of the combat team have returned to the rural farming mode.

The tranquility and vitality of Baiyun Village, as if the worries and chaos had never happened before, this beauty is in stark contrast to the world outside.

Right now, the whole village's attention is focused on the spring seeds, and they don't know that the outside world is full of wars and chaos.

On the second day after Song Shaoqin returned to the village, he started a regular work mode, and rested at home for a day to calm down his family's heart, not to mention that his body was fine.

**
At this time, the coal mining area in the back mountain.

"Second Master, do you see if this is what you want?"

Cao Tianrong suppressed his excitement, and pointed to the black thing on the wooden table to ask for instructions.

Years later, he and Mai Dong took over the errands in the coal mining area. They stayed in the coal mining area for a month and a half and did two things. coal for processing.

And the coal they dig out from underground coal mines can be divided into four categories: raw coal, raw coal, mixed coal, and lump coal.

It was the first time for both of them to contact coal mines, and they also learned a lot of knowledge points that they didn't know before.

The so-called raw coal is unprocessed coal dug out of coal mines, while raw coal refers to the raw coal excavated from the ground, which has been screened and processed to remove gangue, pyrite, etc.

The main role of this raw coal is in industrial raw materials and civilian raw materials. The raw coal is sieved, and the sieved pieces of different sizes are lump coal.

As for blending coal?It is a mixed coal processed by blending several different types of coal with different properties according to a certain proportion.

In the first half of the month, they urged the reform-through-labour workers to dig coal, and directly filled the two factory sheds at the foot of the mountain. After that, they began to try to process the coal according to the second master's instructions.

Their main research and production is coal and briquettes.

Although the newly mined coal can be burned directly, it contains impurities, which will cause certain pollution to the environment and must be washed with water.

That is, by stirring, separating, and dissolving, the coal is crushed into smaller particles so that it can be better mixed with water, and then the coal particles are soaked in water so that the water can penetrate into the interior of the coal, so that the coal is removed during the operation process. impurities and ash in it.

This improves the quality and combustibility of the coal.

They had no experience in the first operation process, and the whole process was very sloppy, but after gaining experience later, the operation process became much simpler. Now they not only process good coal, but also successfully make briquettes.

For this briquette, they also spent a lot of thought and energy. In fact, making briquettes is not difficult, the main thing is how to control the proportion of raw materials.

Although the second master gave them the formula, the recorded text is one thing, but the operation is another.

Compared with processed coal, the production process of this briquette is much simpler. It is to use coal powder and yellow clay, mix them with water according to the proportion, stir them into mud, and then directly press them into shape with a briquette mold, and finally dry them. That's it.

At first, they were inexperienced and did not directly use molds. Instead, they cut into small pieces, added coal powder into the dustpan, and directly rolled them into coal balls with their hands.

Now that the briquettes are made, they tried it out, and the effect is very good, but he and Mai Dong have successfully become a charcoal man.

"Very good. It's the result I want. How is the trial effect?" Song Shaoqin looked at the coal and briquettes on the table with satisfaction, which was consistent with what he saw in the book.

Mai Dong said, "Don't worry, Second Master, we have already used it, it is similar to what you said before, but the coal still has a certain amount of soot during the combustion process."

"Well, let's think about this coal carefully, and try to make it burn with less soot." Song Shaoqin continued to encourage his subordinates.

Although coal is currently unable to achieve the most perfect smoke-free level, it is processed by the masses and civilians, and the beneficiary groups are those poor people who do not have too many warm clothes in winter.

This coal does have some disadvantages, but its fire resistance is much better than charcoal.

As for briquettes, this thing is also called honeycomb briquettes in modern times. It can be used by merchants and middle-level and high-level households. After all, with this briquettes, you don’t have to bother to pile up firewood, and it doesn’t take too much trouble to use it.

"Yes, Second Master."

Cao Tianrong and Cao Tianrong responded in unison, and accepted the new task very straightforwardly. This was also a challenge for them. Through the contact and knowledge during this period, they have now also developed a great interest in this coal.

I heard that the most common and simple use of this coal mine is to make coal and briquettes, but it has many uses and functions, and even has very amazing functions.

Of course, they also heard about it from the second master, but they can't imagine how amazing it is, but their hearts are full of expectation and desire to explore.

For an afternoon, Song Shaoqin spent time in the coal mine. He not only visited every production process, but also discussed and started research with Mai Dong.

It wasn't until evening that he returned to the Song family compound in black.

"Oh~ Shaoqin, why are you here? How did you get into this state?"

Xu Wanqing was washing her son's little hands in the yard, and when she looked up, she looked at her second younger brother, who had always been beautiful and bright, and walked in in a black suit. This was the first time she saw such a dirty image.

"Second uncle has become a big black egg~"

Brother Cheng looked at the dark second uncle, was slightly taken aback, and immediately covered his mouth and snickered.

There is a child in the village who is not only black, but also has black clothes, so the children in the village call him Heidan, and now there is another big Heidan.

Song Jingze, who came out after hearing the movement, immediately laughed ruthlessly, "Hahaha~Second brother, you have this time too, did you go into the coal mine to pick up ashes? Why are you covered in black coal ash all over your body?"

Song Shaoqin glanced over coldly, "Is it funny?"

Isn't it just that the clothes, face and hands are covered with soot? He walked around the coal mining area, and coal was everywhere. Isn't it normal to be contaminated.

He went up to the mountain to inspect the results temporarily, but did not change into suitable work clothes. It was difficult for his robe not to be contaminated with soot.
