Chapter 45 Brick Factory and Cement Factory
Seeing that the temporary researchers quickly entered the state under Harper's management, Xia Lin was relieved of the progress of the laboratory, and once again came to the industrial park that only had a prototype.

The smelting and calcination skill points of the dwarves are absolutely full. No matter how complicated the kiln body is, under their guidance, it is simple and clear. Even this group of half-grown children who have only played with mud can do it well. .

But even so, the endless accidents during the construction were somewhat beyond Xia Lin's expectations.

The first is the lack of manpower. Although Xia Lin planned the manpower and working hours in detail in the plan, in reality, the half-grown children in the slums did not provide as much labor as imagined. In addition, Xia Lin was greedy for progress and chose to build With three shaft kilns, the manpower on the construction site was soon stretched.

The main reason is that Xia Lin found that he had no one to make bricks? !

However, Xia Lin is easy to solve this point. During this period of time, Xia Lin and his group have attracted the attention of the fish teeth who are close at hand. From time to time, people come to find out what they are doing here.

In order to dispel their doubts and temporarily ease the relationship between the two parties, Xia Lin asked Roy to negotiate with them and provide a new job for the residents on their site:
Gather clay to make bricks.

The specific remuneration is one copper bis for ten adobes that meet the standard, and an additional 100 copper bis for every 5 yuan of bricks.

This salary sounds high, but it is not easy to meet Xia Lin's standard.

First, go to the river to get the clay yourself, then crush the clay and sieve it, then add water and knead it five to six times, and only then can the mud be poured into the mold to shape it.

After this step, it is the work of Xia Lin’s side to place these bricks near the vertical kiln to build a high level, separate them with sand, and make full use of the waste heat emitted by the kiln for drying.

This kind of work is quite heavy. A novice can make about 200 yuan adobe a day and get 30 copper pes, while a skilled worker can only make 400 yuan adobe and get 60 copper pes. Requests will be screened out.

Excluding the commission of fish teeth, it can only be said that it is much better than working as a contractor at the dock.But even so, it can be expected that the strength of the fish teeth will increase a lot.

In order to make Yutou's life not so easy, Xia Lin specially asked Roy to make a request, that is, the wages are paid directly to the workers, and if they want to get a commission, they can only be handed over by Yutou or Yutou members to ask for it in person.

People have a strange characteristic. Things that have not yet been obtained are often part of expectations. In the end, there are not so many things that are sent out, so it is barely acceptable.

But if they take away part of what they have already got, then these people will often hold a grudge against the person who took what they had.

Xia Lin didn't expect to arouse the dissatisfaction of the brickmakers and let them overthrow the fish teeth, but as long as there was a rift between the two parties, it would be much easier for Xia Lin to pull out the fish teeth that had lost their roots in the future.

With the participation of this group of local brickmakers, the three shaft kilns soon began to fire red bricks.

Then Xia Lin encountered the second problem, that is, the poor infrastructure of the slums and the high transportation costs resulted in intermittent coal supply.

But this is easy to solve. Xia Lin, who is rich and powerful, hired a cargo ship directly at the pier to send the coal to the pier for loading, and then go down the tributary of the Seine River to reach the small water bay near the construction site.

The current is gentle and the water depth is high, so unloading there is no problem.

After solving these fragmentary problems, after seventeen days, the three vertical kilns finally fired enough bricks. Xia Lin hired ten more craftsmen from the masons' guild in the imperial capital, and asked them and the dwarves to use these red bricks. Bricks and cement mortar build the kiln body of the wheel kiln.

When the 3.2m high, 6.8m wide, and 12.6m long wheel kiln was completely built, Xia Lin finally breathed a sigh of relief.

The simple wheel kiln he designed has twelve doors and eight kiln chambers, which can be fired in rotation when firing bricks.Two kiln chambers are dry, two kiln chambers are preheated, two kiln chambers are fired, and two kiln chambers are cooled.

After a batch of red bricks are fired, the flame can be moved along the circular kiln to the next two kiln chambers. The cooling kiln chamber will absorb cold air due to convective heat transfer, and heat it into hot air in the firing zone. Enter the pretropical and dry zones.

In this way, the flame rotates and moves in the kiln, and eight kiln chambers can continuously produce bricks. A batch of two kiln chambers with a size of 3.4*2.8*2.6m can produce bricks worth 4 yuan.

With 4 yuan of bricks a day, Xia Lin felt that as long as the bricks and fuel could keep up, his industrial park would be perfect soon.

For this reason, he expanded the scale of brick-making workers, bringing their total number to 200, and at the same time developed a new type of work, that is, the familiar brick-moving workers in previous lives.

It takes four days for one round of firing in the wheel kiln. In one day, the brick mover needs to move 4 yuan of fired and cooled red bricks out of the kiln chamber, and at the same time transport the same amount of finished bricks to the kiln chamber according to the vertical order. It is neatly coded in a straight and criss-cross manner.

This process must not be done by Xia Lin's direct employees. Naturally, only brick movers can be hired.

Three copper pes per 100 yuan of bricks, this work intensity is higher than that of brick making, but the income is also greater. It is easy for a strong and skilled brick mover to move 1 yuan of bricks a day.

Even if the nutritional status of the people in the slums is not good, three to four thousand yuan bricks can still be achieved, and that means an income of hundreds of copper pess. money.

Therefore, when Xia Lin started recruiting, even many of his employees were tempted, but after thinking about it, although they only received 50 copper pess salary, they were as easy as brick movers, and they were still "joined" File" people.

According to the cake Xia Lin drew for them, they will be the managers of the factory in the future, and their salaries will be raised again, so why bother to grab a job that is so exhausting every day?
When the construction of the huge wheel kiln was completed and the production started, the shaft kiln cement designed by Xia Lin had also started to produce this kind of raw material—cement, which is indispensable for various constructions.

The firing method of cement is extremely simple. Use clay to add water, limestone, gypsum, fine sand and make a slurry, then send it to the millstone for grinding, then dry it, and mix it with charcoal powder to a size of 10-30mm in diameter after reaching a viscous level. The raw material balls are sent to the vertical kiln for calcination together with charcoal blocks after drying.

What is obtained after calcination is cement clinker, but in order to achieve good performance of cement clinker, there must be a crushing and grinding process. Xia Lin designed a simple temporary grinding device for this purpose.

A wooden box with a cover on the top of the grinding disc is connected to a pipe and a material box, the other side is connected to a blower, and the top is a transmission device of a windmill grinding disc.

In this way, two people rotate the grinding disc through the transmission device, and the other manually blows the air, and the cement dust ground by the grinding disc can be blown like a pipe and deposited in the material box, thereby continuously obtaining finished cement.
