Mineral powder batching machine

1.

The small simple concrete mixing plant is composed of material conveyor belt, mixing machine and batching machine

Material transportation consists of three parts:

aggregate transportation. The advantages of belt conveyor are large conveying distance, high efficiency and low failure rate. Belt conveyor is mainly applied to the mixing plant with aggregate temporary storage bin, so as to improve the proctivity of the mixing plant

powder transportation: the available powder for concrete is mainly cement, fly ash and mineral powder. Screw conveyor is widely used in powder conveying. The advantages of screw conveying are simple structure, low cost and reliable use

Liquid transportation: mainly refers to water and liquid additives, which are respectively transported by water pump

2. The main mixing machine is divided into forced mixing and self falling mixing according to its mixing mode. Forced mixer is the mainstream of mixing plant at home and abroad. It can mix many kinds of concrete, such as fluidity, semi-rigid and rigid. Self falling mixer is mainly used to mix mobile concrete, which is rarely used in mixing plant

The batching machine is used to store and measure all kinds of aggregate in concrete or asphalt mixing plant, and transport it to the mixer according to the preset formula, and mix with cement, fly ash, mineral powder, additives, water, etc. to form concrete

basic requirements of the equipment

1. The weighing should be fast, and the maximum quantity of each weighing should be greater than the demand of the mixer for the material, so as to ensure that the mixer will not idle because of waiting for ingredients

The accuracy or error of proportioning should meet the requirements of concrete construction technology. Due to the impact of falling materials and the distance between the feeding device and the weighing bucket, the weighing can not reach the expected accuracy. Therefore, it is generally stipulated that the weighing error of cement, water, coarse and fine aggregate and additive is 1%, 1%, 2% and 1% of the material weight

In order to meet the needs of preparing various grades of concrete, the weighing equipment should be able to quickly change the weighing weight. Fourthly, the structure of the weighing device should be simple, the operation and control should be convenient and reliable

2.

Because the manufacturers are different, the equipment configuration is also different, and according to the actual needs of users to customize suitable for customers, so the price difference is relatively large

for raw materials, the consumption of various raw materials for each cubic meter of concrete should be calculated according to the mix proportion, including cement, fly ash, mineral powder, sand, stone, admixture, water, other admixtures, etc. the consumption of raw materials multiplied by the unit price is the cost of raw materials

Labor cost, machinery cost, water and electricity cost and maintenance cost are related to proction scale, and workers and machinery should be relatively fixed. The higher the monthly output, the lower the cost allocated to each cubic meter of concrete

the investment of a set of HZS35 mixing plant is about 210000 yuan. If the concrete truck, forklift, Weighbridge and experimental equipment are added, the cost will be higher

extended data:

4. Weighing system is one of the important parts of concrete mixing plant, and it is the key part that affects the quality and cost of concrete. It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing
aggregate weighing generally refers to the system of weighing sand and stone, which is commonly used in concrete batching machine. It can complete the proportioning of aggregate materials according to the user's design. With electronic measurement, it has the advantages of accurate weighing, high proportioning accuracy and fast speed, which greatly improves the proction efficiency of concrete mixing station
weighing of powder, as the name suggests, is to weigh powder, cement, mineral powder, fly ash, etc. Also through the control system for accurate ratio, weighing, high accuracy
liquid weighing is commonly used for weighing water and additives.

5. The main equipment of the concrete mixing plant is the concrete proction line, mainly including: batching machine, belt conveyor, mixer, etc., which is controlled by the control room. The laboratory of the mixing plant is mainly responsible for the test of raw materials, such as sand, gravel, cement, mineral powder, fly ash, water recer and so on, the test of concrete performance, the selection of concrete ratio and so on. You write down the mailbox, and I'll give you a of the concrete test training materials in my hand (edited by a university, which contains the instrument list, use method, test rules, management system, etc.) Has been sent to your email.) Remember to give points!!!!

6. Concrete proction equipment is what we often call concrete mixing plant equipment. According to the different needs of users, the concrete proction line adopts different equipment, but the main equipment is the same, which can be divided into five main mixing machines, material weighing system, material conveying system, material storage system and control system. Tengfei mixing plant declares one point: the main equipment of concrete proction line with different specifications is the same, but the size of proction capacity:

1. The main mixer

is JS double horizontal shaft forced concrete mixer, which is the mainstream mixer used in mixing plants at home and abroad. It can mix various kinds of concrete, such as fluidity, semi-rigid and dry hard< Material weighing system is the key component that affects the quality of concrete and the cost of concrete proction. It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing. The proction of different specifications of concrete mainly depends on the weighing system< The material conveying system consists of three parts:

a; At present, there are hopper conveying and belt conveying in mixing station. The advantages of hopper lifting are small floor area and simple structure. The advantages of belt conveyor are large conveying distance, high efficiency and low failure rate

B. powder conveying; The available powder materials for concrete are mainly cement, fly ash and mineral powder. At present, screw conveyor is widely used in powder conveying, and pneumatic conveying and scraper conveying are used in large mixing plants. The advantages of screw conveying are simple structure, low cost and reliable use

C. liquid transportation mainly refers to water and liquid additives, which are respectively transported by water pumps< 4. Material storage system

the available material storage methods of concrete are basically the same. The aggregate is piled in the open air (there are also closed silos for large commercial concrete mixing plants in cities); The powder is stored in a fully enclosed steel structure cement silo; Admixtures are stored in steel containers< Control system

mixing station control system is the central nervous system of the whole equipment. The control system has different functions and configurations according to the different requirements of users and the size of the mixing station. Generally, the control system of the small mixing station available at the construction site is simpler, while the system of the large mixing station is more complex.

7. The specific configuration can be reced or complicated. Generally, the js750 main machine is equipped with climbing bucket. If the concrete quality requirements are not high, it doesn't need automatic batching. Just buy a main machine with climbing bucket, and use a small forklift refitted by a tractor to add materials to the climbing bucket. The concrete mixing plant is composed of mixing system, aggregate supply system, metering system, control system and external supporting equipment. Forced mixer is the mainstream of mixing plant at home and abroad. It can mix many kinds of concrete, such as fluidity, semi-rigid and rigid. The self falling mixer is mainly used to mix the flowing concrete, which is rarely used in the mixing plant at present. According to the structure, the forced mixer can be divided into planetary mixer, single horizontal shaft mixer and double horizontal shaft mixer. Among them, the comprehensive performance of double horizontal shaft forced mixer is the best< The aggregate supply system consists of three parts

aggregate conveying: at present, there are hopper conveying and belt conveying in the mixing station. The advantages of hopper lifting are small floor area and simple structure. The advantages of belt conveyor are large conveying distance, high efficiency and low failure rate. Belt conveyor is mainly applied to the mixing plant with aggregate temporary storage bin, so as to improve the proctivity of the mixing plant

powder conveying: the available powder for concrete is mainly cement, fly ash and mineral powder. At present, screw conveyor is widely used in powder conveying, and pneumatic conveying and scraper conveying are used in large mixing plants. The advantages of screw conveying are simple structure, low cost and reliable use

liquid material transportation: mainly refers to water and liquid additives, which are respectively transported by water pump< The measurement system is the key component that affects the quality and proction cost of concrete, which is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing. In general, the mixing plant with less than 20 cubic meters per hour adopts the superposition weighing method, that is, aggregate (sand and stone) is weighed with a scale, cement and fly ash are weighed with a scale, water and liquid admixtures are weighed separately, and then liquid admixtures are put into the water scale bucket for pre mixing. In the mixing station with more than 50 cubic meters per hour, the independent weighing method of each weighing material is mostly used, and all weighing is controlled by electronic scale and microcomputer. The weighing accuracy of aggregate is less than 2%, and the weighing accuracy of cement, powder, water and admixture is less than 1%.

4. Control system

the control system of mixing station is the central nervous system of the whole equipment. The control system has different functions and configurations according to the different requirements of users and the size of the mixing station. Generally, the control system of the small mixing station available at the construction site is simpler, while the system of the large mixing station is more complex

5. Composition of external supporting equipment

8. According to the different needs of users, the equipment selected for the whole asphalt mixing plant is different, but the main equipment is the same, which can be divided into five main mixing machines, physical weighing system, material transportation system, material storage system and control system. The whole mixing plant is equipped with JS forced mixing machine, PLD asphalt batching machine, cement silo (also known as cement tank), control system, weighing system, Cement tank truck and so on, let's introce in detail below:
1. The main mixer
is the mainstream forced mixer used in mixing stations at home and abroad, which can mix a variety of asphalt, such as fluidity, semi hard and dry hard in asphalt mixing station.
2. Material weighing system
material weighing system is the key component affecting asphalt quality and asphalt proction cost, It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing; Now there are two ways to transport asphalt mixing plant: hopper transport and belt transport. The advantages of belt transportation are large transportation distance, high efficiency and low failure rate.
2. Powder transportation: the available powder for asphalt is mainly cement, fly ash and mineral powder. Now the widely used powder transportation method is screw conveyor. Pneumatic transportation and scraper transportation are used in large mixing plants. The advantages of screw transportation are simple structure, low cost and reliable use< (3) liquid transportation mainly refers to water and liquid additives, which are separately transported by water pumps,
4. Material storage system
the material storage methods available for asphalt are basically the same. Aggregate is piled in the open air (there are also closed silos for urban large-scale asphalt mixing station)
powder is stored in fully closed steel structure silos, and additives are stored in steel structure containers
5. Control system
the control system of mixing station is the central nervous system of the whole set of equipment. The control system has different functions and manufacturing according to the different requirements of users and the size of mixing station. Generally, the control system of small mixing station available at the construction site is simpler, while the system of large mixing station is more complex.

9. The main equipment of the concrete mixing plant is the concrete proction line, mainly including: batching machine, belt conveyor, mixer, etc., which is controlled by the control room. The laboratory of the mixing plant is mainly responsible for the test of raw materials, such as sand, gravel, cement, mineral powder, fly ash, water recer and so on, the test of concrete performance, the selection of concrete ratio and so on.

10. The main environmental factors that affect the concrete mixing plant are as follows:
1. Dust pollution mainly includes sand and stone yards, which need to be closed by shed according to regulations, and there are water sprinklers inside to spray water to prevent st
2. The powder tank, i.e. cement, fly ash and mineral powder tank, should be closed to prevent st from coming out and polluting the environment
3. There should be sprinklers and water sprinklers in the factory to keep the factory moist, so that the st will not rise
4. The plant should be hardened, and plants should be planted in the Non Hardened places, and st-proof net should be used to cover other places
5. Car washing facilities are set at the factory gate, and the vehicles leaving the station must be washed clean with water, so as to prevent the vehicles from taking mud on the road
6. Due to the noise pollution, the mixing plant will proce greater friction e to the machine belt, thus affecting the rest of nearby residents.
