The fact that the fat steward deducted the workers' monthly money did make Zhu Shun a little disappointed, and he didn't say anything, nodded and left here to go to the coal washing plant.

After seeing the raw coal mountains, Zhu Shun did not dare to leave the original coal mountains, and took a merchant ship to the coal washing plant.

It's the beginning of winter.

Snow particles suddenly floated in the sky, and the snowflakes were not big, and they fell into the Yongding River and smashed out water waves.

Zhu Shun, who was standing on the deck, walked back to the cabin, put on a satin winter jacket outside, and glanced at the newly developed thermometer of the Beiyang Naval Academy.

-12 degrees Celsius.

Now it's just that it's already so cold in the beginning of winter, and it's really going to be a small cold and a big cold season, and I don't know how many people will freeze to death and starve to death.

Zhu Shun walked out of the cabin and stood on the deck facing the howling cold wind: "Chongzhen is also pitiful enough, internal worries and external troubles, and encountered the hell difficulty of the hell difficulty during the Xiaoice River period. ”

Thinking of the crown prince Zhu Cihong, who has become an admirer of great men and is constantly moving closer to great men, Zhu Shun is full of confidence and expectations for Daming.

The merchant ship was empty and unloaded, and it didn't take long for it to arrive at Matou, where the coal washing plant was built.

The broad horse's head was empty and deserted.

Zhu Shun stepped down from the pallet, looked at the empty horse head but felt that the horse head was a little small, I believe that it will not be long before this place will become one of the busiest horse heads in Shuntian Mansion.

The horse's head has been hardened with cement, and the ground under Zhu Shun's feet is no longer a dusty exchange of land, but a hard cement ground.

Walking out of the horse's head, two concrete roads appeared.

Zhu Shun glanced at the coal washing plant on his right, far away, but he could still hear the roar of the steam engine.

On the left is a wide cement flat field, which is supposed to be the warehouse of the coal washing plant, which is used to store the graded coal.

Zhu Shun followed the cement road on the right to the coal washing plant, where there was a tall reinforced concrete water tower on the north side of the plant, and the steam engine was constantly pumping water into it.

The coal washing method used in the coal washing plant is the flotation method, which has high requirements for the concrete waterway, and the concrete waterway under the water tower is much wider than the waterway of the ordinary steam mine.

Wearing a gold-threaded satin winter jacket, Xu Jixin stood beside the wide waterway and watched as the workers kept pouring coal into the coal washing pool.

Zhu Shun saw Xu Jixin, who liked to wear a white robe in the past, and changed into a gold-threaded satin winter jacket that only wealthy businessmen would wear, and smiled dumbly: "This kid is really instilling wolf culture in the workers all the time. ”

There are also more than a dozen students from Beijing Normal University standing next to Xu Jixin, which is also very different from the students of other colleges.

Most of the students from the other faculties wore the Songjiang purple cloth winter jackets that were distributed every winter by the Kyoto Normal University Hall, and they were proud of it, after all, it had the words "Kyoto University Hall" on it.

However, few of the students of the Institute of Metallurgy wear the school clothes of the Beijing Normal University Hall, basically everyone has a silk winter jacket, and anyone who wears the school clothes will be looked down upon by the metallurgical students.

After Xu Jixin established the wolf system, the monthly money of the students of the Institute of Metallurgy was not fixed, but they earned silver by their ability.

The greater the ability and the more capable he is, the more money he earns, and all the students who usually wear school uniforms must be wastes with little ability.

Only capable metallurgical students can wear silk winter jackets, because they earn enough silver.

After a long time, the students of the School of Metallurgy inevitably had conflicts with the students of other colleges, the students of the School of Metallurgy felt that the ability of other students was low, and the students of other schools felt that the utilitarianism of the Metallurgical School was too heavy.

A student from the School of Metallurgy of Beijing Normal University next to Xu Jixin saw Zhu Shun coming over and quickly reminded the dean.

Xu Jixin hurriedly walked over with the students, usually speaking sharply and giving people a sense of domineering, and when he met his mentor, Zhu Shun was only respectful: "The mentor is here." ”

Zhu Shun nodded, looking at this set of flotation coal washing method: "Old Seven, introduce the flotation method to the teacher." ”

The teacher was about to test the research results of the Metallurgical Institute, and Xu Jixin's face couldn't help but show a trace of pride.

Fortunately, a few of his senior brothers are not here, if they see his unbeaten face here, they will definitely find some reasons to reprimand this domineering little junior brother who also likes to dig people.

Xu Jixin walked near the waterway, pointed to the water tower in the distance and said: "Master, the flotation method is to separate raw coal of different densities into grades through the impact of water flow, and remove dust and waste rock. ”

"Reducing the ash value of the raw coal and ultimately classifying the coal."

Introducing the role of the concrete water tower, Xu Jixin walked to the south and walked about half a mile before stopping.

The smashing sound of the steam crusher crushing the ore, Zhu Shun's ears were a little inaudible, and it was all the sound of ore crushing.

Xu Jixin pointed to the steam mill and said loudly: "The flotation method is divided into three steps, crushing, flotation, and classification. ”

"The large raw ore is first crushed into small pieces through the crushing workshop here, and then transported to the flotation tank."

The steam crusher crushes large pieces of coal into small pieces, and a skilled worker stops the steam miller, and other workers standing next to him quickly begin to load the small pieces of raw ore onto wheelbarrows and transport them all the way to the coal washing pond, where they are emptied into the coal washing pond.

Zhu Shun, Xu Jixin and others followed the workers whose faces were covered with black ash all the way to the coal washing pond, which had stored enough coal ore.

As the sluice gates were opened by the workers guarding the reinforced concrete water tower, a large amount of water gushed out of the concrete water tower and rushed down the waterway into the coal washing pool.

The waterway between the concrete water tower and the coal washing pond is much steeper than the normal waterway, in order to allow the water to have a high impulse.

The water rushed into the coal washing pond like a rushing flood, constantly washing, taking away the dust and impurities from the coal.

Some of the substances in the raw coal, depending on the density, will sink to the bottom of the water or float on the surface of the water.

Workers began to salvage the material floating on the water, which was essentially the same material, and completed the rough separation of the coal.

After salvaging the material floating on the surface of the water, the black water flow in the coal washing pond will be discharged to salvage the material at the bottom of the pond.

After all the materials have been salvaged, they are graded.

Xu Jixin looked at the various materials salvaged and continued: "After grading, the coal is divided into coal gangue, medium coal, grade B refined coal, and grade A refined coal. ”

"Stored separately in each warehouse, the flotation method is basically completed, and the next step is to load and traffic as needed."
