On the south bank of Long River, in a huge valley, there are several large houses being built next to the originally lonely casting yard.

The house has not been built yet, but there are already many people busy inside.

Zhu Qizhua looked at the big guy in front of him and couldn't help but feel extremely proud.

This is a machine about 100 meters high. The upper is like a house and the large frame is iron. The lower two large rollers that are thicker than people are also iron. Even the conveyor belts that send ore upwards are made of iron.

There is no way, there is no rubber conveyor belt at this moment, so he can only use iron.

He was sure that no one in this world had ever made such a big steel monster, and this was a product of a cross-age!

When it comes to the technical content inside, it is actually nothing. This is a stone crusher, which means transporting large pieces of ore from the conveyor belt to the iron frame above, and then the ore will be crushed by two large rollers and leaked out from below.

In the past, gravel was manually smashed with hammers, and the efficiency was too low, so the red gravel was thinking about making a large stone crusher.

Now the stone crusher has been assembled and debugged, and large pieces of limestone have been piled up in half the room. I am just waiting to try the effect of this stone crusher.

Zhu Qizhe admired his masterpiece proudly, and then ordered loudly: "Send steam and turn on the machine."

"Puff", a burst of steam blew up, and then the two huge rollers under the rock crusher turned, and the conveyor belt next to it was like a pedal waterwheel was also moved.

They have tried these two moves several times, so there must be no problem, just don’t know how effective the gravel is.

Zhu Qizhe waved his hand and said cautiously: "Try sending a few ore in first."

When the craftsman next to the conveyor belt heard this, he quickly picked up a shovel and pushed a few pieces of limestone larger than watermelon onto the conveyor belt.

There were a random sound of "bang", and a few limestones quickly fell into the stone crusher, followed by another "kaka" sound, and dust suddenly flew under the stone crusher.

After the strange sound slowly disappeared, Zhu Qizhe waved his hand and said, "Stop the steam and shut down."

The stone crusher quickly stopped operating, and he quickly squatted down and looked at the gravel below.

How to say the effect of this gravel?

The limestone was crushed, but it was not very uniform. The larger ones were smaller than the fist, and the smaller ones were not as thick as the fingers.

Well, it was still fine, the thing he was most worried about didn't happen.

To be honest, he was afraid of seeing broken iron blocks, because the surfaces of the two rollers were not shiny, but with semi-circular teeth. The roughly function was to scrape the ore into the middle, which might have a little effect of increasing uniformity.

He didn't know much about this. He just had a vague impression that the big rollers of broken or something were the structure. As for the specific gravel effect, it is still to be tested further. He was just worried that the strength of the cast iron would not be enough, and the teeth on the large rollers would fall down with the gravel.

Now it seems that the strength of cast iron seems to be enough, that's all.

Next is the next step.

They ordered people to make more than one stone crusher, as well as mixers, drying furnaces, large millstones, etc.

Of course, these are not final products, and they must be tested and improved continuously. He just wants to make some cement quickly and see how the cement is effective in various proportions.

He squatted under the stone gravel machine for a while, then suddenly slapped his head and said to himself, "Oh, why am I so stupid?"

It turned out that he forgot to add the guide plate, and all the broken ore fell off directly under the crusher, so someone had to pull it out.

He said to himself in annoyance for a while before waved: "Come on, pull out the gravel below and go into the mixer. Remember, eight to two, eight shovels of gravel, two shovels of clay."

When the craftsman next to him heard this, he quickly took a shovel, a shovel and other things to pull out the gravel and shovel into the mixer.

The mixer is right next to it, so it doesn’t take much effort, just that this process is too troublesome.

Zhu Qizhe shook his head slightly and said, "Meng Hou, I forgot something. You can speed up the iron plate below the exit of this stone crusher and fix it obliquely. In this way, after the gravel falls from the exit, it will slide into the front of the stone crusher, and there is no need to go down there and pull it down."

Upon hearing this, Bi Maokang nodded repeatedly and said, "Yeah, I understand."

This is the case for the time being. For the mixer, because it is a trial production, it requires research on the ratio of various raw materials. The red utensil was not too big, so he ordered people to make a few small ones.

As for the structure of the mixer, it is also relatively simple. It is a cylinder with an iron cross-like thing added. When the steam engine is turned on, the iron cross will rotate rapidly, and the raw materials inside will be stirred and stirred quickly, and it will be stirred evenly soon.

Next is calcination or drying.

To be honest, he is not as familiar with this process as Bi Maokang and Song Yingxing. After all, people know how limestone is burned into lime, but he has never seen it before.

So, he directly handed over this process to Bi Maokang and Song Yingxing, and he didn't care about the drying furnace.

After calcination or drying, it is ground.

What they did was two large millstones, one of which was fixed and the other was driven by a steam engine, and kept spinning on it.

The structure of this thing may be wrong. Maybe this kind of grinding a grinding lime powder and cement powder should not be used. However, there is no need to take care of the redware waste. The structure of the grinding a wheel can be improved in the future. Now, what he needs is to produce the finished cement product as soon as possible to see the effect.

After grinding the mixture of limestone and clay into powder, he ordered people to mix the powder 20% of the coal powder and iron ore powder in a ratio of 8 to 2, then stirred it evenly, grinded it carefully, and finally sifted it with a fine sieve to remove the pieces inside. He finally got a pile of cement.

Of course, this is not necessarily the best ratio. He is not sure about the specific ratio, and he is just a roughly vague impression.

If this ratio is suitable, you have to try it out before you know.

As for how to try, this is simple.

He directly ordered people to add some sand, gravel and water to the tried-made cement, stir it into a paste, and then pour a wooden frame with a thin iron stick in the middle. When it drys, you will know whether it fits or not.

It was not a short time before the cement was completely dry. He didn't stand there and wait. Then, he changed various ratios and made many different cements.

What are nine to one, seven to three, eight to five to one, eight to five, more coal powder or more iron ore powder, etc., he asked someone to try it out, then cast it into steel and cement blocks, and mark the matching ratio next to it.

There is no way, you have to try something you haven't done. It may succeed in one go, or you may not know how many times it will succeed. In short, you have to try it to know.

He kept trying various ratios and constantly casting steel and cement blocks, making a huge field unable to be placed, so he gave up.

A few days later, the first batch of steel and cement blocks finally settled, and it was finally time to witness the effect.

He directly ordered people to remove the wooden frames around him, and then he would take turns to hit the wooden frames, shovels, hammers, etc.

No matter what the ratio of the cement processed in this way, the strength is definitely incomparable to lime. When Bi Maokang, Song Yingxing and others saw that the cement block was a little unable to dig the hoe after it solidified, they were really shocked.

However, the red utensil is not very satisfied with it, because these steel and cement blocks can basically be easily smashed with a hammer.
