With the rapid development of the domestic economy and the continuous advancement of the modernization of urban transportation, the consumption of stabilized soil has increased year by year. It is particularly important to ensure that the stabilized soil mixing plant can produce long-term stable and efficient output. Today, the editor invited Jinhuiyuan Mechanical Engineer to explain in detail the correct operating specifications of the stabilized soil mixing plant, hoping to play a positive role in future actual production.

1. Preparation before starting
1. Check whether the connections of all parts of the stabilized soil mixing station mixer are firm and reliable, whether the lubricating oil of each part is filled to the specified value, check whether there is leakage at both ends of the main shaft, check whether the storage bin door is opened and closed, whether the gap between the mixing blade and the lining is within the specified range, whether the transport belt is damaged, and whether the mixer can rotate normally;
2. Check whether the electrical control system is safe and reliable, whether there is leakage, short circuit, and whether the insurance device is normal;
3. Check whether the air compressor is running normally without abnormal sound and leakage, and ensure that the pressure is kept within the specified range;
4. Ensure that each weighing device measures accurately and the error is within the standard range;
5. The equipment can be started only after confirming that there are no safety hazards in the silo and belt transportation.

2. Precautions during work
1. After starting the mixing system of the stabilized soil mixing station, it should be run empty first, carefully check the operation of the machine, and check whether the direction of the mixing shaft is correct. After confirming that the mixing system is correct, production can be carried out;
2. Closely monitor the belt conveyor and feeding system to prevent excessive or large stones and other foreign objects from entering the silo;
3. Closely…

“Can we still open a concrete mixing station when environmental protection inspections are so strict?” “Will it be difficult to invest in an environmentally friendly concrete mixing station? Is the investment cost high?”… The above questions are the most frequently asked questions on the Jinhuiyuan Machinery website recently, and these questions are also one of the reasons why investors are hesitant about mixing stations. Commercial concrete is indeed an investment project with large market space and considerable profits, but strict environmental protection inspections have caused many mixing station companies to complain. So, with perfect technical support, is it really difficult to open an environmentally friendly commercial concrete mixing station? How about the cost? This article will explain it in detail for you.

Is it difficult to open an environmentally friendly concrete mixing station? You decide!
Society is progressing, technology is developing, and although environmental protection has always been a major problem restricting industrial production, with more and more environmentally friendly equipment and auxiliary devices entering the market, opening an environmentally friendly commercial concrete mixing station is no longer a problem, and achieving efficient and environmentally friendly production has become commonplace. Speaking of this, we have to let the site prove it.

As can be seen from the picture, the commercial concrete mixing station is not only equipped with a pulse dust removal device, but also equipped with dust shields in the storage bin, conveyor and other parts that are prone to dust. Therefore, when the entire mixing station is in operation, there is very little dust spillage, and the working environment is relatively clean and tidy.

The mixing station uses bucket lifting loading. Although the commercial concrete mixing station is equipped with…

The top five equipment maintenance tips for concrete mixing plants are all here, collect them now! Concrete mixing plants are composed of a mixing host, material weighing and proportioning equipment, material conveying equipment, material storage equipment, a control system and other ancillary facilities. The smooth operation of a mixing plant is inseparable from its daily maintenance. Mixing plant equipment requires daily and careful maintenance to minimize the occurrence of machine failures and increase the service life of the equipment. This article combines some guidance given by Jinhuiyuan Mechanical Engineers to introduce the top five equipment maintenance tips for concrete mixing plants, hoping to be of some benefit to all mixing plant users in their daily production in the future.

Maintenance of the mixing main machine
1. Check whether the sealing chamber, distributor inlet and outlet, and sealing pipeline are unobstructed every shift, and whether there is enough lubricating oil (grease) at each lubrication point and reduction box;
2. Observe whether the grease in the oil storage cylinder of the electric lubrication pump is used up every shift, and replenish it in time when it is almost used up;
3. The accumulated materials inside and outside the mixing drum, the discharge door, etc. must be completely cleaned and rinsed with water at the handover of each shift. The bonding materials that are not rinsed clean must be chiseled off regularly;
4. Check the mixing blades regularly every week, adjust and tighten them once to prevent accidents caused by blade shedding.

Maintenance of material weighing and proportioning equipment
1. Each shift must check and adjust the soft interfaces of the metering bucket to ensure that there is no looseness in the length and to ensure metering accuracy;
2. After winter shutdown, the water supply system and the water stored in the admixture supply must be drained to prevent water from freezing and cracking the equipment;
3. If the admixture pump is seasonally shut down, it must be flushed regularly to prevent the additives in the pipeline and pump from precipitating and sticking, causing blockage. …

With the continuous development of society, the progress of infrastructure construction is constantly advancing, the popularity of concrete mixing stations is increasing year by year, and the mixing station equipment production industry has developed extremely rapidly in recent years. Since the 18th National Congress of the Communist Party of China proposed the construction of ecological civilization, the development of many industries has been restricted. After several generations of innovation and development of concrete mixing stations, “green mixing stations” will replace traditional forms and become the development direction of the industry. The key to building an environmentally friendly mixing station is to reduce and reasonably control the various industrial pollution generated during the production process. The key to building an energy-saving mixing station is to reduce the required human, material, electricity and other resources from the preparation to the daily operation process, and comprehensively improve the input-output ratio.This article will combine the opinions of Jinhuiyuan Mechanical Engineers to start from the problems existing in traditional mixing plants in terms of environmental protection and energy saving, and propose corresponding improvement measures and maintenance precautions for different links.

Environmental protection measures for mixing stations
Traditional mixing stations mainly produce “waste residue, waste liquid, dust, noise” and other forms of pollution during use. Different pollution in different parts requires different purification treatment methods.
1. “Dust” control measures for mixing stations: isolation and recycling. Environmentally friendly mixing stations should adopt “double insurance” measures for dust treatment. The first is isolation, that is, all dust pollution sources in the mixing station system are sealed and sealed to isolate the pollutants from the outside world first; then take specific measures according to the different causes of dust generation…
