"If the public wins, how many stones can the iron mill in the factory grind in an hour?" Chen Xu turned his head and asked if he won or lost.

"It's about forty!"

"Well, it's about 6,000 catties of corn when it is replaced, and the speed of this big water mill is more than twice as fast, and there is no need to rest halfway, how can you calculate that you should grind 20,000 catties of grain in an hour......"

"Isn't that nearly two hundred stones~"

There was a burst of exclamation all around, and many people couldn't close their mouths directly.

"It's just two hundred stones, such a big pair of iron mills, one or two stones of grain poured into it and the grinding teeth can't be filled, come on, load the grinding bucket above, go to the factory grain warehouse and pull fifty stones of grain to come and test the grinding......" Chen Xu waved his hand.

"Go quickly, go quickly~" A group of people couldn't wait to urge, Gong Lvsheng hurriedly ran outside the mill to give a few words, and the steward took a group of people to go straight to the factory a few miles away.

Under the command of Hu Kuan, several craftsmen brought in a wooden grinding bucket, holding the hammer Ding Lingqi for a while, a round large wooden bucket was installed on the top of the large iron mill, with this feeding hopper similar to the rice beater, feeding the grinding is much more convenient than the small stone mill, otherwise it will not be able to catch up with the abrasive speed of the iron mill.

Half an hour later, seven or eight ox carts came with bulging bags of hemp, filled with wheat.

"Master Hou, the grain has arrived, a total of fifty stones of wheat!" Responsible for leading the team to report to the manager.

"Okay, the personnel are in place, start feeding, Hu Kuan, tell the dam to open the gate and release water!"

"Yes, Master Hou!" Hu Kuan excitedly scolded the craftsmen on the top of the mill, with the sound of the bamboo flute and the continuous waving of the flag, Shi Lu, who was standing on the top of the dam, got the order to command the helpers to slowly open a sluice, and as a stream of clear river water gushed out from a large hole in the dam and hit the huge waterwheel, the stationary waterwheel began to rotate slowly, and almost at the same time, the big wooden wheel in the mill began to rotate, driving the big iron mill to rotate together.

"Whoosh~" As the iron mill slowly turned, after a few turns, brown flour with bran flowed out from around the iron mill like a waterfall.

"Hurry up~" a craftsman yelled.

Because as Chen Xu said, a few stones of grain were poured into the hopper, and with the rotation of the iron mill, it fell to the bottom in an instant like a whirlpool, and several worker slaves could only carry bags of grain and continue to pour them into the mill bucket.

"Stay safe!" Seeing that a worker slave almost stumbled and fell into the feed hopper, Chen Xu couldn't help but remind loudly.

Once this big waterwheel starts to rotate under the impact of the water, there is no way to stop immediately in the event of an accident, and even with the big iron mill will keep rotating, and the grinding eyes of the iron mill are a foot thick, and the legs that fall into it can be twisted into meat sauce.

The waterwheel under the dam turned faster and faster, and finally slowly stabilized, and this large-scale waterwheel, which was the first ever to be powered by hydropower, also completely ignited the enthusiasm of the spectators on the riverbank, and tens of thousands of people cheered excitedly to witness this great miracle together.

There are hundreds of people gathered in the mill, and the audience outside is different, in addition to some princes and princes who really came to see the excitement, there are also officials from the Ministry of Industry and the Academy of Sciences, as well as craftsmen and craftsmen of the factory, including Zhang Cangfangkuan, these scientists, they are more around the big iron mill to witness this mechanical miracle of gear transmission, see the big iron mill crazy devouring grain, the flour around the iron mill falls like a waterfall, and then flows down the inclined hopper, Then they are loaded into a bucket truck and pulled down the slope.

"Hahaha, it's a success, Master Hou! We did it! Fang Kuan burst into tears of excitement, jumping and roaring in the mill to make a ghost crying wolf howl.

Fifty stone wheat, if you use ordinary household stone grinding, three people take care of it a day, it is estimated that it can grind fifty kilograms of flour, that is to say, a family can not grind two stones a day, but with this large iron mill driven by hydraulic gears, it does not take half a minute to grind a stone of flour, which is the biggest difference between machine and manpower, not only throughput but also fast and stable tireless.

In less than twenty minutes, as the last bag of wheat was poured into the iron mill, and then the grinding bucket made a sound like an old cow drinking water, only to hear the hula for a while, a bag of wheat disappeared in an instant, and soon turned into brown flour and flowed down from all around the iron mill, and the flour no longer appeared after the big iron mill turned several times again, indicating that the fifty stone wheat had all been ground into flour.

"Close the sluice passage and check the condition of the waterwheel!" Chen Xu waved his hand.

"Yes, Master Hou!" Fang Kuan wiped his tears and rushed out of the mill, the craftsman on the roof waved the command flag again, Shi Lu on the dam commanded the helpers to close the sluice, the big waterwheel slowly stopped after turning half a circle, the water volume of the drainage channel next to the dam increased instantly, and the river water roared down the layers of dam stones like a water dragon and fell under the dam, churning up violent foam and waves.

"Fifty stone of grain, more than a moment, Hou Yeguo will not deceive me!" Zhang Cang's face was dull as he looked at the helper who was transporting flour under the passage and muttered to himself.

"It's so fast!" Several princes and princes in brocade robes also supported their chins with their hands, feeling that they couldn't close their mouths at all.

"Hou Ye's whimsy, whimsical and wonderful, this non-immortal guidance is absolutely impossible to succeed......"

"Master Hou, please wait for me!" Some craftsmen and craftsmen directly knelt on the ground and kowtowed to Chen Xu.

"Okay, okay, hurry up and check the gears of the stone mill and the wooden wheel, hang the stone mill up and clean up the grain inside, it is estimated that you can still sweep a stone of grain that is not completely ground out!" Chen Xu himself couldn't stop smiling.

Soon, a craftsman instructed a few workers to lift the big iron mill with a rope around the iron teeth, and a helper used a broom to sweep out the wheat that was not completely ground in the iron mill, almost seven or eight buckets, which could only be brought back and processed with a small mill to steam steamed buns.

As for the flour ground by the big iron mill, Chen Xu went down to the storage pool of the channel to take a closer look, and found that it was much finer than the stone mill, basically there was no difference in the flour of later generations, even the bran was all ground, and it was basically impossible to clean it out with a flour sieve, and it became a real whole wheat flour, and there was no problem with steaming steamed buns to make steamed buns.

The experiment was a complete success, and the next step was to put the finishing touches on the mill, to build a huge house to include both the mill and the passages, and to complete the surrounding storage plant.

Chen Xu gathered Hu Kuan, Shi Lu, Gong Yisheng and several stewards in charge of the dam and the mill together for a simple meeting, the main topic was to pay attention to the daily use and maintenance of the mill, as well as the safety issue, all the rules and regulations are modeled on the factory, written as a wooden sign and publicized in a conspicuous position, of course, but also to tell the management of the people who come to see the excitement, do not let them climb the dam and the waterwheel, usually allow the public to enter the mill to watch, but absolutely not allowed to get close to the gears and the big iron mill and so on.

This big waterwheel and mill are estimated to be known to Xianyang today, and then they will spread all over the world with newspapers.

As an epoch-making example of an automatic industrial machine, Chen Xu hopes that more people will see, observe, and figure out the principle, and then promote and apply the gear to a wider range of lives, rather than hiding it as a treasure.

"Dean Zhang, how is it? Ben Hou didn't deceive you, if you can summarize a more precise gear occlusion law, the work efficiency of this big iron mill will be improved, and this transmission mode of gear will greatly solve many practical problems in life, it is the most important part of the future development of the machine......" On the way back, Chen Xu invited Zhang Cang to take a car to communicate together

"Master Hou, what is a machine?" Zhang Cang became very interested in this new term.

"The so-called machine is composed of a variety of different parts, and then used a non-human animal power to drive the operation of the organ utensils, the ultimate function of this utensils is to replace the human energy to solve some of the hard work in life, so as to greatly reduce the intensity of human labor, such as this hydraulic mill, is the first real sense of the machine product I invented, it relies on water power to propulsion, can tirelessly continue to run for many years, as long as the dam does not damage the water flow does not stop, it can continue to operate, One day and one night can grind more than 200,000 catties of grain, enough to meet the daily rations of 200,000 people in the entire Xianyang City, but on weekdays, it takes tens of thousands of people to solve the same work, which is the role of the machine......"

"The thresher, blank drawing machine, and polishing machine invented by Hou Ye are not counted?" Zhang Cang asked suspiciously.

"No, those that can help people complete their work faster and more conveniently, but they are not real machines, at most they are semi-artificial mechanical devices, just like horse-drawn carriages, people invented horse-drawn carriages, which can pull more goods, making it more convenient, faster and more comfortable for people to go far away, but horse-drawn carriages are not yet machines, unless one day we invent a device to replace horses, without feeding them forage and grain, they can keep rolling forward like a waterwheel, so that the carriage is not the current carriage, but a kind of mechanical carriage......"

"God, how is this possible?" Zhang Cang looked at Chen Xu dumbfounded.

"How is it impossible if we install a huge windmill on a carriage, the wind blows the windmill to turn, and then passes through the gears to the wheels......"

"Master Hou, are you serious?" Zhang Cang looked at Chen Xu directly.

"Of course, you can go back and organize people to try this thing, but the wind is not as stable as the water, and it can't be controlled by a dam like water, but this is an idea, it must be no problem when the wind is strong, of course, the best application of wind power is on the boat, you can also have people hang sails on the boat, so that even if the boat is against the current, it can travel thousands of miles a day......"

"Gear...... Windmill ......" On the way back, Zhang Cang sat in Chen Xu's carriage and kept muttering these two names, not even knowing the construction site of the Weihe Bridge.
