Baotou, into the end of August, has begun autumn, several days of high temperature, so that the climate has become dry, without a trace of wind in the summer, people feel bored.

Knowing that he was tirelessly shouting, on the construction site, the climate was hot, so that the workers were working at such a temperature, they were very tired, Yang Yuanzhao was also considerate of the workers, and the three meals a day were very rich, and even Ren Dan, herbal tea, etc., were also prepared together to prevent the workers from suffering from heat stroke due to the high temperature.

Fortunately, the workers of this era are far stronger than those of later generations, and occasionally a few people who are dehydrated due to high temperatures have also been relieved by normal saline and herbal tea, and there have been no worse results.

From the preparation of the cement factory, to now, more than a month, many hired workers, after a short period of training, are basically able to work, they are divided into more than a dozen different parts, followed by many masters, the front of the gang and the back, but also a good look.

This month's time, mainly Li Mingsheng is in charge of the cement plant, the machine is basically installed, for some trial operation of the machine, some adjustments and improvements have been made, the machine is more suitable for the production of this plant, is conducive to play the overall joint force.

Any factory, in order to achieve the optimal state, initially needs a reasonable and scientific design, according to the actual situation, also needs to be constantly adjusted, the most important thing in the factory is the machine, advanced machine, can increase efficiency, but there is no efficient team. The advantages of the machine cannot be brought into play at all. It will even do useless work, resulting in huge waste.

Today is different from the past. At noon, there was a thundershower, the rain was refreshing, so that the summer heat slightly subsided, and occasionally there was a small wind that did not know where to blow, which made people feel more suitable, and there was a huge roar in the huge workshop, all the equipment of the cement plant. The installation has been completed, and the separate test run has also been done, and now, it is to concentrate all the machines and carry out the overall test machine.

This test machine work is very critical, related to whether the cement can be smoothly and smoothly produced, but also determines the level of output, from Li Mingsheng to Yang Yuanzhao are very important, personally appeared at the site of the test machine. In addition to the 150 veteran masters, there are about 80 newly recruited mechanical workers, and 70 workers who have stood out through the training of the guò system. A total of 300 people, forming a complete and complete team.

This is currently the best and most experienced team in the cement plant. This team will also serve as a permanent team for the entire cement plant, when the cement plant is running at full capacity in the future. They will be divided into 4 or 5 shifts to ensure the 24-hour continuous production of the cement plant.

Similar machines qì idling and carrying the real yàn. In the past week, it has been carried out more than ten times, almost every time, it is these workers present, the workers are relatively familiar with the steps of production, but the expressions on the faces of the master and ordinary workers are slightly dignified and nervous.

This time, unlike the previous test machines, it is a full machine test, with enough materials, at the end of the production line, there are also prepared cement barrels, when the time comes, you can directly fill the barrels and package, and there is no difference from daily production.

The steam engine is already started, the power required by the cement plant, relatively huge, a total of 36 large steam engines work together, at this time, it is only a trial run of the production line, the braking is used 8 units, a huge roar sounds, rolling up bursts of black smoke, along the special chimney, discharged into the air.

Yang Yuanzhao has considered the pollution problem of the steam engine as much as possible, this era, there is no way to solve it for the time being, unless the application of electricity makes a breakthrough, with cleaner and more powerful electricity, instead of the steam engine, which needs to be in the motor, transformer, capacitor and many other aspects, have gone to a considerable breakthrough can be, at present only with pollution in exchange for development speed.

Fortunately, Yang Yuanzhao came from later generations, and later generations have studied gas engines and other aspects to a certain extent, and when making these steam engines, he took this into account, and used many methods to save sewage and reduce pollution in later generations, for example, replace the original casually used coal with better anthracite, and find it here with the heritage of Shanxi, a major coal province, will not increase the cost much, and the pollution is still acceptable, and refer to some characteristics of the internal combustion engine in later generations, plus some protection and filtration measuresWhen the machine is running and all kinds of equipment are working, the black smoke has decreased significantly, and the sound is not as loud as it used to be, and the pollution of this steam engine is far less than it seems.

After the roar of the steam engine, the speed and the generation of water vapor have reached a stable state, the power shaft is hung on the machine, and the huge equipment in its static state is slowly running under the impetus of the machine.

The whole production line, using a segmented design, transmission device, using two separate steam engines, powerful horsepower, uniform speed operation, so that the crawler and conveyor belt smoothly forward, the crusher and the mill, respectively, occupy the other two steam engines, the remaining four, is used in the mixture, the huge mixing room, can hold dozens of tons, even hundreds of tons of materials at a time, only a strong power, can push them to run.

The huge machine began to run, the decibel in the workshop, obviously rising, but still in the bearable Cheng dù, the conveyor track, the huge limestone, was transported to the inlet, here there is no choice of canvas track, is a steel track, all the steel of the track, are brought by later generations, not only excellent flexibility, the load-bearing capacity is also quite strong, only in this way, can make the huge, seemingly irregular lime, at a steady speed, to the place to go.

Lime and clay, both of which have been treated to a certain extent, and the largest is only more than 200 kilograms, under the strength of the machine, slowly crossing the top of the 15-meter-high crusher and entering the feed port. The limestone fell into the crusher and a loud sound was heard. It was the sound of limestone hitting the walls of the grinder, huge and loud.

Most of the workers. In less than 15 minutes, at least hundreds of tons of various materials were injected into the crusher, they were all in the position above the crusher, and then, according to the push of gravity, passed through the crushing area below, where there were jagged gears. The intricate bars, under the powerful steam power, rushed to the limestone, these bars and gears, using the cemented carbide steel brought by later generations, in terms of hardness and speed, far better than the steel of this era, a burst of machine qì propulsion, added limestone and clay. It's all in pieces.

This is the first wave of crushing, which is mainly to break up the oversized structures and lay the foundation for the next mill, which is extremely noisy here. In the future, workers working in this workshop will receive special earplugs. Prevent injuries caused by excessive noise.

Below, a huge just sieve. The pieces that meet the needs are sifted below. Through the conveyor belt, enter the next step of the medium-sized grinder, and the remaining unqualified, will pass through another conveyor belt, re-go through the just step, until they meet the requirements, the whole sorting basically does not need manpower, only two workers, will accumulate too much material on the sieve, with the machine control zhì steel rod, to beat them, to ensure that the work of screening and transfer is carried out smoothly.

The second crusher is a little smaller, and the various equipment is more fine, and he will further crush the pieces that have been processed above, and the huge theory and drill bit under the machine are driven by power, like a giant, and exert great power, once the raw materials enter the crusher, they become fine stones, and then directly pass through the next crusher.

Such a crushing process, divided into three times, a sieve is smaller than a time, reciprocating, and eventually will form a relatively fine small pieces, these are finally added to the mechanical mill, by the Austrian mill, after a certain modification, expand its grinding surface, enhance the material, with the alloy of later generations, instead of the steel of this era, in terms of wear resistance and commincability, much stronger than the original, in the specially designed feed port and grinding effect, each small piece, finely ground into powder, powdered and mixed evenly, is the key to cement production.

Eventually, the chunks of material turned into fine powder, and in the middle, a conveyor belt brought a bunch of reddish-brown stuff, the same finest powder, very different from other cement plants.

These powders were added to the cement under the suggestion of Yang Yuanzhao, which is one of Li Mingsheng's research results.

Yang Yuanzhao only knows a little about cement, but he has also heard that the improvement of cement labeling, the most fundamental, is the material added, iron ore powder is the most common and common kind of additives, casually told Li Mingsheng, and told him that adding some iron ore will increase the strength of cement, so that the cement combined after water condensation is more solid.

Solidity and coagulation, is one of the important indicators of cement, Li Mingsheng engaged in the cement industry for decades, in recent years, because of the face of foreign brand competition, but also in order to increase the competitiveness of Qixin, he began to enter the cement research, although there is not much professional knowledge, the chemistry is also a little understood, but rich practical experience and decades of experience, so that he really achieved some results, Qixin Yang ash field of new products, is in his joint efforts with two British engineers, completed, Not only the overall performance indicators exceed the cement imported from the UK, but the cost is also a big reduction.

Based on the industry rules, Li Mingsheng did not provide such a new product, but the ideas and steps, he knew very well that the equipment provided by Yang Yuanzhao was far more sophisticated and advanced than the Qixin factory, and the only shortcoming was that I am afraid that it was only time, the time was very tight, and the task was very heavy.

Adding iron ore is a very common and efficient method in cement production, Li Mingsheng studied according to this, almost for the first time, there was a very good effect, and the performance in some aspects exceeded the new products of the Qixin plant.

This made Li Mingsheng greatly encouraged, continue to add, several times of small-scale real yàn, a total of 35 different proportions, of which only the addition of iron ore, there are 21 kinds, basically find out the proportion of iron ore added, at present, through the guò conveyor belt, is specially from Wuhan to get iron ore, in steelmaking, a little higher sulfur, will affect the quality of steel, but here, there is no problem at all, through guò accurate calculation, is the best additive, can make the hardness of cement, The coefficient of expansion, adhesion and many other aspects have a high improvement, which are the most critical steps.

Because the firmness of iron ore is far higher than that of limestone, and the amount used is not much, Yang Yuanzhao did not choose to buy iron ore directly, but got a small mill, crushed at the place of origin, and transported it is a finished product that is crushed well, cut and mixed evenly, and this finished product has undergone magnetic separation and sorting, so it can be said that the purity and accuracy are relatively high.

The two masters stepped forward to calculate the amount and specific gravity of clay and lime respectively, and then analyzed the amount of iron ore added, these iron ores need to be added at the end, Li Mingsheng personally calculated the addition ratio, adding a certain proportion, it will have a huge effect on the finished cement product. Two masters are in charge of this matter, personally staring at this, and three or four clerks, starting from the addition of materials, the addition of iron ore powder, not casually added, must reach a certain content, this has just begun production, everyone is still relatively unfamiliar with this, need to add at the same time, according to the actual situation, to calculate clearly!

"Alright, stop!" A master said loudly, the conveyor belt stopped, the red powder stopped on the conveyor belt, Li Mingsheng stepped forward, asked a little about the number of jù, and then nodded, several workers stepped forward, adjusted the conveyor belt, from the original position, connected to the mixing room, and then, as long as the machine started, the conveyor belt will inject materials into the mixing room.

The tracks that transport the other two raw materials have already been adjusted, and the huge mixing chamber is connected to three different conveyor belts, which are slowly moving forward under the impetus of power.

The roar came, after a master inspection, and then issued an order, the power shaft was connected to the conveyor belt again, the conveyor belt was in the roar, and it ran again, all the workers arrived at the designated position, the whole cement machine was tested, and the first step was crushed, which was successfully completed, and began to enter the second step of mixing.
