Cement and steel plants are still somewhat similar in appearance, with high chimneys and combustion furnaces.

The only difference is that the cement plant uses the limestone and clay blasted down from the mountain as the main raw materials, which are crushed, batched, and ground into raw meal, and then fed into the cement kiln to calcine the mature material, and then add the appropriate amount of gypsum to the clinker and some of the remaining materials to grind finely to become cement.

The production of cement is divided into two types: dry production and wet production, and the dry production is now used.

Dry production is generally the method of drying and grinding raw materials at the same time, or first drying and grinding into raw meal powder and then feeding it into a dry kiln to calcinate mature material, but there is also a method of adding an appropriate amount of water to make raw meal balls and sending it to the Libo kiln to calcine mature material, which is called semi-dry method, which is still one of the dry productions.

Many of these processes, not to mention that Lu Yuan does not understand, even Pan Haodi himself only understands some of the theoretical knowledge, or rely on Han Xiaolei when he laid down Zhangjiakou, while snatching some equipment from the cement plant, some old workers brought back by the way with experience, fortunately, the quality of the cement produced is not bad.

As soon as you enter the scene, you can hear the roar of the earth, which is the sound of diesel generators driving the crusher to grind stones, and the air is densely covered with all kinds of dust, and the working environment is extremely poor.

The coal inside the mouth of the kiln was blazing, and the chimney above was spreading smoke in all directions.

In order to prevent the target from being exposed, the height of the chimney was very low, and special measures were used to allow the smoke and dust to spread at low altitude so as not to be noticed by Japanese fighters.

As a result, the smoke and dust became more dense, and even the ground in the valley near the cement plant, and even on the leaves, were covered with a thick layer of dust, and the workers worked in such an environment without the slightest precautions.

"Hello Commander, Engineer Pan is ......"

As soon as they saw Lu Yuan and his party coming, the workers greeted them happily, and the wind under their feet redoubled their efforts, and the happy appearance made people feel happy involuntarily, even if the sweat rushed out of the ravines on their dusty faces, it could not stop their enthusiasm for work.

"Now the No. 1 kiln has been fully operational, can produce 10 tons of cement per day, No. 2 kiln will also start production recently, it is estimated that starting next month, our cement plant can reach more than 20 ......tons of output per day," a worker in charge of production said to Lu Yuan with great interest, obviously they are extremely proud of their work.

Lei Ming, Han Xiaolei and others muttered on the side: "Lu Yuan, the cement has been supplied to your Trojan County first, and when the project in your Trojan County is almost over, the remaining cement will be supplied to us first-cement houses, who doesn't want to live in it......"

"We'll talk about that later!"

Lu Yuan didn't pay attention to the words of the two at all, just frowned and said, "Have you been working like this all the time, not wearing masks or anything?" ”

"Masks?"

The worker in charge of production pouted and smiled: "Captain Lu, we used to wear that thing when we were in the Zhangjiakou factory, and it smells like stinky feet when we sweat, and everyone doesn't like to use it, so it's not mandatory to wear it, not to mention that there are no ......masks here."

"Yes, Captain Lu, just do it, everyone still feels happy, hahaha......" Several workers passing by laughed.

"That's not going to work!"

Lu Yuan snorted coldly and said: "Work is important, but people's safety is even more important - do you know that working in this dusty environment for a long time, and without any protective measures, it is easy to get pneumoconiosis?" Once you get pneumoconiosis, it's all over! ”

"Pneumoconiosis, what's that?"

As soon as he heard this fresh term, not to mention those workers and Lei Ming Han Xiaolei, even Pan Haodi Su Yan, a cultural person like Pan Haodi and Su Yan, who had learned five cars, looked dazed.

Not to mention this era, even in the early stage after the founding of the People's Republic of China, the protection of occupational diseases is a blind spot, if it weren't for Lu Yuan's life in the era of the information explosion, even he would not have known, let alone these people.

"In short, it is an extremely serious disease, once it is obtained, it can never be cured, and life is better than death!"

Lu Yuan explained a little and immediately ordered: "Commander Lei, Commander Han, you have cotton in the liberated area, right?" Make some simple masks out of cotton gauze and send them to the workers in the shortest possible time – masks will have to be worn in the future, whether working in a cement plant, a steel plant, or a coal mine...... Remember, you must wear it, I will come to check it at any time, but if you find that you don't wear a mask, you will not be allowed to work in the factory in the future! ”

For this order, the workers didn't understand it very much, but they also knew that Lu Yuan was for their good, so even if they didn't want to, they still agreed, but Lei Ming Han Xiaolei looked depressed, and babbled about what kind of cotton is nervous, it is not enough to make clothes and quilts for the soldiers and people, where is there extra cotton and the like, but seeing Lu Yuan's face, there is no room for negotiation, so he can only shut up stupidly.

However, the second order about Lu Yuan directly made everyone fry.

"Also, any worker who works in the mine has to take turns off – a month in the mill, and a different wave of people has to come in, and they have to rest for at least two months before they can continue to work here – a month, two months off, understand?" Lu Yuan continued.

"Lu Yuan, this can't be done!"

Lei Ming Han Xiaolei was the first to complain: "Do you know how many people are needed to work in this mine every day? And they are all young and strong, all the young and strong people in our liberated areas and your Trojan County, except for those who are out of production, and it is not enough for the rest of the people to rotate here - I am saying, our two factories are treasures, and ordinary people dare not call them over, what if they are mixed in with bad elements to sabotage, what if we stab the affairs of our two factories to the little devils, what should we do? ”

"Commander Lu, working in this factory is the same as being a soldier in a war, only soldiers who have been on the battlefield have combat effectiveness, this skilled worker can ensure the output of the factory, if a batch of people are changed every month, the output and quality are difficult to guarantee......"

Pan Haodi and some of the leaders in charge of production also screamed bitterly.

Even those workers shouted with bitter faces: "Captain Lu, you just let us do it!" We are not afraid of hardship, nor are we afraid of pneumoconiosis, as long as we can work for a few more days and make more money, we will die, then we are willing......"

Seeing everyone's unanimous opposition, Lu Yuan refused to change his opinion at all, and said coldly: "No matter how many difficulties there are, we must do it according to my requirements, I really can't do it, we would rather have less output, even if the factory is not open, we must not make a lot of patients because of these factories!" ”
