What is a flour mill?

Abstract: Flour is the food we often use. Do you know how flour is made? Yes, it's a flour mill. Mill is a wheat processing machine that uses external force to grind wheat into small particles, and separates flour particles of different sizes by adjusting the size of sieve holes to get small flour particles. Mill is a kind of roller mill, which is mainly used for grinding raw materials such as wheat, corn, sorghum, rice and millet. This machine can be used as a stand-alone machine, and it can also be used as supporting equipment for small and medium-sized flour mills. We should compare and inquire about word-of-mouth more when buying a flour noodle machine, so as to choose the right machine. Let's look at the details of the flour mill. 1. What is a mill?

Mill is a wheat processing machine that uses external force to grind wheat into small particles, and separates flour particles of different sizes by adjusting the size of sieve holes to get small flour particles.

Second, the principle of the mill

Grinding head: in the grinding part, two grinding rollers with oblique teeth are used to roll the grain into the gradually narrowing grinding mouth to produce extrusion. Because of the different rotating speeds of the two grinding rollers, grinding force is generated to break the grain into powder, and the broken grain flows into the screening part.

Round roller: it is stirred and thrown out by a rotating fan, so that the screen wire flows into the outlet and the slag is sent to the rear slag outlet. And then processed, so that any required power can be obtained through sequential cycling.

Three, the classification of the mill

Flour machines can be divided into different categories according to different requirements. There are several main points.

According to the number of mills, it can be divided into single mills, double mills and multiple mills (that is, mills).

According to the size of flour mills, they can be divided into small flour mills, medium flour mills and large flour mills.

According to the advanced technology of mill, it can be divided into traditional mill (skin-core mixed mill) and modern mill (skin-core separated mill).

Traditional mill (skin-core mixed mill) includes stone mill and traditional steel mill. When processing wheat, the milled skin-core mixture is not separated, but directly milled again, which makes the flour darker.

The modern mill (skin-core separation mill) uses a circular screen to filter, separate the skin-core mixture from the ground skin-core mixture, and then separate the skin and core for grinding. The flour ground in this way is relatively white.

Fourth, how to choose a stone mill flour mill?

Take a look: look at the size of the manufacturer, whether it is professional, the length of production time, business license and certificate of honor. Among them, the production scale often determines the production and technical ability of an enterprise, which is the most important. If an enterprise has a large scale, long production time and strong professionalism, its products are often of reliable quality and high reputation. On the other hand, if a factory is small, many parts are assembled by others, with low technical ability and low credibility. If the customer can't stand asking, then they have to think about it. In addition, even the same model products of the same company will have different output, performance and price because of different configurations. This is also what customers need to ask. For example, there are five cone screen mills, and there are differences in the size of grinding rollers among the five mills, and there are also differences in the output of cleaning equipment. I understand it when I ask, and it is much clearer when compared with other manufacturers.

Listen: Go to the customer to listen. Customers are the best witnesses of products. Listen to the quality, performance and service of the products they use. If they have a good reputation, they can buy with confidence.

Comparison: After investigation, analyze and compare the performance and price, and choose the machine with high cost performance or moderate price.

Verb (abbreviation of verb) Matters needing attention in the use of mill

1, strictly abide by the safety operation rules of flour mill equipment and wear labor protection articles according to the operation rules.

2. Before starting, carefully check whether the motor, switch, circuit and grounding are normal and firm, and check whether the mechanical control components and buttons are in the correct position.

3. Check the coincidence degree and firmness of the upper and lower dies, and check whether each positioning device meets the requirements. Always check the coincidence degree of the upper and lower molds; The pressure gauge shows whether it is within the specified range.

4. After the equipment is started, it will idle for about 2 minutes. If abnormal sound or fault is found, stop the machine immediately and eliminate the fault. You can't start working until the equipment is normal. If there is any abnormality, stop the machine immediately, check the cause of the abnormality and eliminate it in time.

5, pour wheat again, must cut off the power supply, stop running. When the machine is working, people are not allowed to stand behind the flour mill equipment. If any abnormality is found during operation, please stop and correct it. It is forbidden to calibrate the equipment by hand during operation, so as not to hurt your hand.

6. When the fuselage shakes, tighten the connecting bolts between the grinding head and the frame. When the output drops, the spring should be tightened to ensure the gap between the two ends of the grinding roller is consistent, and the worn grinding teeth should be repaired in time.

7, flour temperature is high, should loosen the grinding roller; If the grinding roller is seriously worn, it should be repaired or replaced; When the temperature of the machine is too high, it must be stopped to dissipate heat. Bran can't be produced, which may be caused by the wrong direction of spindle, lax sealing of screen frame or broken screen.

8, no powder or less powder, because the screen is blocked. Mechanical voltage is too low, distribution line is short-circuited, line contact is poor, control circuit is open, fuse is blown, etc. , resulting in startup failure. When using the mill, always add lubricating oil to all parts of the machine to reduce wear and tear.
