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…

　　Concrete mixing plants can be mainly divided into two types: commercial concrete mixing plants and engineering concrete mixing plants. Due to their production…
　　The overall quality warranty of the mixing station is one year (excluding wearing parts such as lining plates, low-voltage electrical appliances, and feeder belts), and the whole machine is under lifetime warranty.
　　If the equipment fails, whether within or outside the warranty period, upon receiving the notification, the maintenance personnel will arrive at the site as soon as possible and start repairs.
　　When choosing a concrete mixer manufacturer, you should understand the manufacturer’s production scale, whether the concrete mixers produced by the factory meet international standards, and whether the plate thickness meets the standards. Then pay attention to whether the manufacturer’s after-sales service is in place. Large manufacturers have a sound after-sales service system. If there is a problem, you can contact the manufacturer at any time to solve the problem according to the process, so that customers can use it with more confidence. According to these points, it is worth referring to pay attention to quality and service.
　　First, the transmission system should be flexible and without abnormal noise; second, the transmission of belt conveyors, bucket elevators, etc. should be stable, flexible, high brake, no abnormal noise, and no chain jam; third, check the sensitivity and accuracy of the metering system; fourth, pay attention to the lifting temperature of the reducer, which should reach the temperature on the certificate of conformity; fifth, the inlet and outlet of the metering bucket should be smooth, without accumulation of material, overflow, etc.; sixth, the safety valve should not leak.
When choosing a concrete mixer, first of all, we should consider the size of the production scale, the size of the construction site, the situation of the attached equipment, the management function, the technical performance of the equipment, and so on…

“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.
