How to mix mineral ingredients of loader

1. Forklift electronic scale is a kind of measuring equipment for railway bulk cargo loading measurement based on Dacheng weighing instrument combined with the needs of users in practical application. It can be used for vehicle loading measurement, limited load measurement and earthwork measurement. It is composed of sensor and weighing display instrument, which can measure dynamically or statically
the weighing instrument of forklift electronic scale can print date and time, display peeling, zero setting, store weight data and information, etc., which will not affect the normal loading work. According to the specified proceres, the accuracy error can be controlled within 1%. All kinds of imported and domestic loaders can be installed. Such as ferroalloy ingredients, gypsum ore ingredients, these can be installed and used

Operation method:

1. After the installation of the whole machine and the empty running test, the storage hoppers can be fed respectively, and the discharge gate of the cement silo and the feeding port of the screw conveyor can be opened for debugging

2. Start up according to the instruction manual of batching controller

3. Input the set value of sand, stone and cement according to the requirements of the instruction manual of batching controller. If one of the materials is not used, the set value must be zero

4. In the batching process, when the weight of the material in the weighing hopper reaches the set value, the feeding belt conveyor will stop automatically, but at this time, a part of the material still falls into the weighing hopper from the air, and the weight of this part of the material is called the drop

In order to ensure the accuracy of proportioning, the drop value of materials must be corrected. According to the different batching controllers, the way to modify the drop value is different. XK-314 batching controller is manual correction, and other batching controllers are automatic correction, so there is no need for user correction

After batching, record the actual weight value (display value) of each stage: material I, material I + material II, material I + material II + material III, material I + material II + material III + material IV, and then calculate the drop value

in order to ensure the batching accuracy, the drop value of materials must be corrected. According to the different batching controllers, the way to modify the drop value is different. XK-314 batching controller is manual correction, and other batching controllers are automatic correction, so there is no need for user correction

extended data:

ring batching and metering, the difference between the set value (advance) and the actual value is between the time when the electrical control signal sends the stop batching command and the time when the material really falls into the metering bucket, so the control instrument sends the stop signal in advance before the material reaches the actual value, The part of the material falling after the signal is called drop

that is: actual number - set number = drop (this drop batching machine instrument can be automatically corrected)

before work, the loader (manual feeding can be used when the batching machine is installed underground) supplies sand and stone materials to each storage hopper respectively

according to the instruction of the batching controller, input the formula to the batching controller (the unused materials must be set to 0). After pressing the batching button, the batching machine will start to enter the automatic batching program

its working process is as follows: first, the material I belt conveyor starts to work and transports the material I to the weighing hopper. When the weight of material I in the weighing hopper reaches its set value, the material I belt conveyor stops automatically; Then the belt conveyor of material II starts automatically. When the weight of the material in the weighing hopper reaches the sum of the set values of material I and material II, the belt conveyor of material II stops and the belt conveyor of material III starts to work. After the four kinds of materials are complete, the machine is in the waiting state

at this time, press the discharge button, the discharge belt conveyor works, and the prepared dry concrete is discharged into the mixer hopper. After discharging, the discharging belt conveyor will stop automatically and start the second cycle batching automatically. After the second cycle batching is finished, it will wait for discharging, and so on

3. You drive the loader. The main work is to feed the mixing plant. There are batching warehouse and mixing station. They are all medium and large-scale construction projects. General small engineering buildings. Is there a large mixing plant. Therefore, the mixing bin covers a large area. There's a lot of space. Then the arrival of spring, the spring breeze, the air is dry. So the site often has dirty air and cement st. It has great influence on human respiratory tract. Close the door, the temperature in the car is high and the cab is hot. You want to install air conditioning in the car, not in your cab. How about closing it? If it's tightly closed. It can be air-conditioned.

4. The method of proportioning calculation is a very complex oxidation-rection process, the gain and loss of oxygen is difficult to determine, the fluctuation of raw material composition and the size of moisture will have an impact on the final result, and the accurate theoretical calculation of sintering proportioning is particularly troublesome in the sintering proction, and it takes a lot of time, so it is very difficult to calculate the proportioning accurately, In general, the simple calculation method is often used in the field batching calculation, that is, the inverse algorithm
the so-called inverse calculation method is to assume a proportioning ratio, and calculate the chemical composition of sinter according to the original data of moisture, burning loss and chemical composition of various raw materials. When the calculation results meet the proction requirements, the proction can be organized according to the proportioning ratio. If not, the calculation can be adjusted again until the proction requirements are met. If there is an error between the calculated ratio and the actual proction, we can analyze the causes of the error and adjust the calculation again. How to determine the proportioning ratio in proction is also a problem that everyone is concerned about. In fact, the determination of proportioning ratio is often based on the requirements of sinter quality index, raw material supply status and raw material composition in ironmaking proction, and combined with the proction cost to carry out reasonable collocation and inverse calculation, so as to obtain the final proportioning ratio
first, when calculating by back calculation method, it is necessary to understand some terms related to ingredients
1. Burning loss: the burning loss of material refers to the percentage of the weight of material sample lost after burning (dry material) at high temperature (1200-1400 ℃) in sintering state
2. Burning resie: the resial amount of material, that is, the resial amount of material after sintering, water discharge and burning loss
3. Moisture content: the moisture content of sintering raw material refers to the percentage of physical water content in raw material, that is, the percentage of evaporated moisture in the weight of sample when a certain raw material (100g-200g) is heated to 150 ℃ for 1H
4. Chemical composition: the chemical composition of a raw material refers to the percentage of an element or compound content in the weight of the dry raw material sample< 2. Specific calculation formula: 1. Burning resie = dry material ratio × 1 - burning loss)
2. TFE in the batch = TFE content of the raw material × The ratio of the raw material
3. The SiO2 in the batch = the SiO2 content of the raw material × The ratio of the raw material
4. Cao in the batch = CaO content of the raw material × The ratio of the raw material
5, MgO in the batch = MgO content of the raw material × The proportion of the raw material
6, Mn in the batch = Mn content of the raw material × The raw material ratio
7, sinter chemical composition
sinter TFE = the sum of TFE brought in by various raw materials ÷ Total sinter resie
sinter SiO2 = sum of SiO2 brought in by various raw materials ÷ Total sinter resie
Cao = sum of Cao brought in by various raw materials ÷ The total burning resie
MgO of sinter = the sum of MgO brought in by various raw materials ÷ The total sintering resie
Mn = the sum of Mn brought in by various raw materials ÷ If there are other requirements, the calculation formula is the same as above< Third, ingredient calculation
ingredient calculation is based on dry ingredients. At present, there are two methods, one is to use dry ingredients, the other is to use wet ingredients, but the purpose is the same. Now most units use wet ingredients, because they can't upload the calculation table, they have to be omitted here.

6. Brother loader loading, who told you there are four kinds of operation methods of pure nonsense ~ (I tell you the truth, you don't want to listen) I went to Shanxi coal mine to learn to open loader when I was 16 years old. I learned it for a month. I've been driving for five years, and now I'm 22, and I don't open it any more ~ but when I was driving, the company with a radius of 10 kilometers admired me ~ what four kinds of operation methods of nonsense ~ I'm sure I can teach you better than your master. First of all, let me know It's really simple ~ ~ the most difficult thing for loaders is level road ~ level road can't work without 3 years or 2 years, because loaders are controlled by terrain ~ I've seen loaders that can be loaded without learning ~ remember to learn how to mp things while loading It's OK ~ but remember to keep it low ~ this is the skill that the middle car can't stop when pouring things ~ so people will look at you like an old hand ~ and then you must pay attention to the maintenance of the car. The shift must be stable. The instant shift must not make the car stop for a long time.. grasp the time difference... The brake and accelerator cooperate well... You also said that you should set the direction when loading ~ this is wrong ~ · loader loading When shoveling things, we must master the time difference of following the car. In short, when reversing, we should adjust the distance of loading. When loading, we must remember to follow the car. Otherwise, we must not load it. If you are not proficient enough, it's easy to have an accident. Finally, I'll tell you that I'm stupid, too. But the loader in Shanxi says that it's pig's hand. If it's five fingers, pigs can drive West ~ don't always feel stupid ~ remember to open more ~ ~ open more when you start school, you should also bear hardships and open more

7. Sinter proportioning methods include quality proportioning method, volume proportioning method and composition proportioning method, which are introced in the book. I'll go back and have a look
