Although the changes brought about by bus companies in Xianyang City are great, they are far less than those outside the city. From the emperor to the peddlers and pawns, the most concerned and discussed every day is the progress of the Weihe Bridge.

Half a month later, the approach bridges on both sides of the river have begun to take shape. The dug embankment is made of bluestone to create a wide stone wall. These stones are glued together with cement mortar. After drying, they are as strong as steel.

The cement, sand and gravel steel bars used for building bridges stacked on both sides of the straits are like small hills.

The sandbank in the center of the river has become the center of the construction site, and it is still piled with a large amount of wood, bamboo and stone. The two piers have been poured and are about to be completed. The scaffoldings built with thick wood and bamboo in the river are about to be connected into one. They look dense and dense, like a wall built by bamboo and wood connecting the banks of the Wei River together, which looks very spectacular.

The dam seven or eight miles below has been repaired and the mill has been repaired. Today is the day to install the iron mill, so Chen Xu took the bus to the location of the water truck early in the morning.

This news was revealed by onlookers a few days ago, so early in the morning, tens of thousands of people were surrounded near the dam, including horses, cars, donkeys, carriages, and carriages, from princes, princes, ministers, and peddlers to peddlers and bars. The bustling hustle and bustle around the dam was filled with the noise, and the noise of the noise in Xianyang City could be heard.

"Hurry up, get out of here, the marquis is here!" The crowd made a way out in the noise.

Chen Xu's carriage drove from the dispersed passage to the river by the river under the escort of a group of guards.

"See Marquis!" After Chen Xu got off the car, Zhao Qing, Hu Kuan, Shi Lu, Magan, Gongshusheng and others brought a large group of managers and craftsmen to greet him.

"No gift!" Chen Xu waved his hand and got out of the car, looked at a huge iron mill that had been transported to the riverside, walked up and walked around and watched it.

The diameter of this large iron mill is similar to the diameter of the factory's large iron mill. It weighs more than 5,000 kilograms. The fan at the bottom is slightly thinner, the fan on the top is slightly thicker, and there is a circle of twenty round iron teeth evenly distributed around the fan.

With the experience of the last time, the pouring of the large iron mill was very smooth. It took only six days from molding to pouring. There was no accident in the middle. Then a special four-wheeled carriage with iron shafts was used, and five oxen and hundreds of prisoners were transported to the riverside.

At this time, many people wearing brocade robes and official uniforms gathered around the iron mill, including the free-standing kings and princes, as well as officials from the Ministry of Works and the Academy of Sciences.

After a group of people greeted him in a mess, Zhang Cang couldn't wait to pull Chen Xu's sleeve and said excitedly: "Hao Hou quickly arranges people to place the iron mill. Cang is very curious about how this big water truck drives the iron mill to operate!"

"It's not bad, the Marquis of Qinghe quickly arrange the hoisting!" Several Marquis who were wearing brocade robes and doing nothing on weekdays could not wait to urge.

"Don't worry, wait until I go to the mill to check the installation location carefully before talking about it!" Chen Xu walked into the mill that had not yet been capped with a smile.

A large pit dug out of the middle of the mill has been built into the required style. There is a circular cement pier in the middle that is a circle larger than the iron mill. There is a circular pit in the middle, just the same size as the diameter of the iron mill. There is also a circle of steel bars as thick as an arm in the center, which is exposed about five inches. These steel bars are embedded in the cement pier for a little over one meter, and each position corresponds to a circle of holes at the bottom of the fan under the iron mill. These are installed after careful measurements.

Around the cement pier is a circular inclined hopper built with cement. After the iron mill is turned, the grated stone and cement will fall into the hopper and flow downwards, falling into an inclined passage below. There is also a storage pool below. The helper loads the stone in the storage pool into the bucket truck. Then someone can pull the truck up by turning the winch above the passage. Of course, it is also possible to push it with human power.

Overall, this design is a factory with semi-mechanized nature in later generations. If a conveyor belt can be designed, it will become very fast and easy whether it is feeding or discharging.

Unfortunately, no good idea can be realized without motivation.

Chen Xu carefully checked inside and outside the mill, and used an iron hammer to hammer the steel bars that fixed the iron mill several times. He found that it was like competing with a mountain. The hammer that smashed the iron hammer bounced up and splashed the sparks, but there was no movement.

"Okay, prepare to lift the iron grinding!" Chen Xu threw down the hammer and nodded.

"All units are careful and prepare for lifting!" Hu Kuan, the commander-in-chief of the iron grinding lifting, shouted excitedly.

A group of soldiers scolded everyone around him and retreated. The slings and Gongshusheng, who had already been ready for the punches and grinding, immediately loudly directed a group of tall and strong prisoners to lift the lower half of the iron mill with a rope with a thick wooden bar. Heyyou shouted a trumpet and carried half of the iron mill into the mill. Several craftsmen in charge of the placement quickly stood around the cement pier and began to observe the location of the holes and steel bars under the iron mill.

"Left~Change half a foot left~"

"Turn three inches~"

"Okay, slowly fall down...slowly, stop...and half an inch to the right..."

With the command of several craftsmen, a group of ragged prisoners carried the iron mill and adjusted slowly. In just ten minutes, the holes under the iron mill and all the steel bars fell in line with each other.

"Square wood, iron hammer~" As Hu Kuan shouted, several helpers brought a few pieces of thick wood and placed it on the iron mill, and then hit the wood hard and then half of the iron mill completely fell into the sunken round pit, completely fixed with the cement pier.

Hu Kuan and Gongshusheng accompanied Chen Xu to check and thought that they had been fully installed, so they started to lift an iron grinding on it.

The upper one is relatively simple. First, place a rotating shaft as thick as a calf in the center. After installation, a group of prisoners also asked to carry the upper half of the iron mill in and then put it on quickly. The two iron mills were placed firmly in the center of the mill.

Looking at the installed iron mill, Chen Xu felt quite excited. His little heart was thrust violently. He repeatedly watched the gears on the iron mill and the huge wooden wheel on the central axle of the water wheel. After comparison, he pushed the iron mill to adjust the position of the two huge gears and then ordered to manually rotate the water wheel for the final gear correction and debugging.

"Notify to turn the water truck~" Hu Kuan ordered a craftsman standing on the top of the mill.

"Ding~Ding~" The craftsman blew a bamboo whistle, then kept waving the flag in his hand. Under the dam, under Shi Lu's command, hundreds of helpers moved the impeller of the water truck together, and the water truck slowly began to rotate.

As the water wheel rotates, the wooden wheel on the spindle also begins to rotate. The iron teeth more than one foot long rotate and hit one of the iron mills with a click.

"Wow~" Driven by the huge inertia of the rotation of the water truck, the half-small iron mill weighing more than 3,000 pounds was pushed and started to rotate without any resistance.

"It's been turned~"

In an instant, a group of craftsmen and craftsmen in the mill, including Zhang Cang, Hu Kuan and Gongshu Sheng, couldn't help but yell excitedly. The countless helpers and craftsmen who were involved in the construction of the mill who were waiting outside the mill also became noisy.

"Quick, push the iron mill forward!"

Chen Xu turned a deaf ear to the excitement and noise inside and outside the mill, and stared at the position where the rotating iron mill and the gears of the wooden wheel intersected. After the iron mill had rotated for half a circle, the two gears began to be a little uncomfortable, and there was obvious dislocation. So Chen Xu quickly ordered several craftsmen waiting around the iron mill to push forward in the direction of rotation together, so that the two iron teeth could be blocked together.

After three more turns, the teeth between the iron mill and the wooden wheel were dislocated again. Chen Xu ordered the craftsmen to push the stone mill to calibrate again.

Twenty minutes passed quickly, and after seven or eight fine-tuning and calibration, the large iron mill and the wooden wheel finally bit together perfectly, and the rotation was very smooth and there was no sign of misalignment. Chen Xu then ordered to stop the rotation of the water truck.

"Do you understand the process of calibrating the gear just now?" Chen Xu wiped his sweat and turned to ask Hu Kuan, Gongshusheng and others.

"See clearly!" The group of people nodded quickly.

Just as the iron mill started to rotate, after a while, the mill cheered lively and for a while, everyone found that Chen Xu had begun to train the gears seriously, so everyone quickly calmed down to watch, for fear of missing any trace of the process.

"Just see clearly. The iron mill and the wooden wheel rely on these iron teeth to rotate. At present, we have not carefully calculated the number and position of the gears. After running for a period of time, we will definitely accumulate an opportunity for errors. Therefore, we must arrange people to check the operation of the gears at any time on weekdays. If there is a misalignment, it must be adjusted, otherwise the gear may be damaged. Don't be too careless!"

"Don't worry, Master Marquis, I will arrange people to keep an eye on you every day, and there will be no mistakes!" Hu Kuan quickly patted his chest and promised.

"Well, especially in the first few days, you must monitor it at all times and summarize the misalignment rules. After finding the rules, you don't have to worry about it. Just arrange people to adjust them regularly~" Chen Xu nodded.

"A pair of iron mills of such a large pair of iron mills, I guess they will definitely be used as a flour soon!"

A marquis in a brocade robe just finished watching the installation and commissioning of the iron mill. Although he felt extremely magical about the gears, he was more interested in the working efficiency of this super huge iron mill.

"Haha, what Wen Jihou said is that the diameter of an ordinary stone mill is less than two feet and the weight is only about two hundred kilograms. The diameter of this pair of iron mills reaches eight feet and weighs more than five thousand kilograms. Not to mention grinding surfaces, bluestone can be ground into fine powder. Grinding flour is definitely a very quick thing!"
