Modern winter concrete mixing station

In the design and configuration of the winter version of the concrete mixing station, special consideration will be given to extreme weather conditions such as low temperature, frost, and snowfall in winter to ensure that the mixing station can operate safely and efficiently in winter.The following is a detailed introduction to the winter version of the concrete mixing station：

I. Basic features

1. Cold-proof and thermal insulation design：
   • The exterior of the equipment is wrapped with cold-proof materials to reduce heat dissipation and protect the equipment from damage in low-temperature environments.
   • Critical components such as conveyor pipes and water tanks are insulated to prevent icing and clogging.
2. Heating system：
   • Equipped with heating devices, such as heating furnaces, hot water circulation systems, etc., it is used to heat raw materials such as aggregates, cement, and water to ensure that the temperature of the concrete during the mixing process meets the requirements.
   • The interior of the mixing host can also be equipped with heating elements to prevent the concrete from solidifying due to low temperature during the mixing process.
3. Special concrete formula：
   • Winter concrete mixing stations usually use concrete formulas with antifreeze added to improve the frost resistance and early strength of concrete at low temperatures.

II. Composition of equipment

The winter version of the concrete mixing station is roughly the same as the ordinary mixing station in terms of equipment composition, but it will be strengthened and optimized for the characteristics of winter.Mainly includes：

1. Mixer：
   • It adopts a double-horizontal shaft forced mixer, which has the characteristics of good mixing quality, short mixing time, and long life of wearing parts.
   • The mixing host is internally equipped with heating elements to ensure the temperature of the concrete during the mixing process.
2. Dosage system：
   • Accurately measure the ratio of raw materials such as aggregates, powders (such as cement, fly ash, etc.), water and additives.
   • Equipped with a heating device to pre-heat the raw materials that need to be heated.
3. Conveying system：
   • Belt conveyors, screw conveyors and other conveying equipment adopt thermal insulation measures to prevent freezing and clogging at low temperatures.
   • During the conveying process, a hot air system can be added to increase the conveying temperature.
4. Control system：
   • It adopts advanced PLC automatic control system and industrial computer synchronous control system to realize the automatic operation and remote monitoring of equipment.
   • The control system has temperature monitoring and adjustment functions to ensure that the temperature of the concrete during the mixing process is within a controllable range.
5. Dust removal system：
   • Equipped with high-efficiency dust removal equipment, such as pulse dust collectors, to reduce dust pollution in the production process.
   • The dust removal system also needs to consider the design of cold and heat preservation to ensure normal operation in a low temperature environment.

III. Maintenance

1. Check the heating device regularly：
   • Ensure that the heating device is working normally and repair or replace damaged parts in time.
2. Clean up snow and frost：
   • Regularly check the snow and frost on the outside of the equipment and on the pipelines, and clean up in time to prevent clogging and damage to the equipment.
3. Replace low temperature lubricating oil：
   • Use lubricants suitable for low-temperature environments to ensure that the transmission system and lubrication system work normally at low temperatures.
4. Strengthen staff training：
   • Train the staff of the mixing station under winter production conditions to improve their identification and processing capabilities of equipment failures, as well as their sensitivity to changes in concrete performance.

IV. Application Scenarios

The winter version of the concrete mixing station is particularly suitable for projects in cold areas of the north or winter construction.In winter construction, the performance and stability of concrete are essential to the quality of the project.The winter version of the mixing station adopts a series of cold-proof, heat-preservation and heating measures to ensure that the concrete can still maintain good performance and quality in a low-temperature environment and meet the construction requirements.

In summary, the winter version of the concrete mixing station fully takes into account the extreme weather conditions in winter in the design and configuration, and adopts measures such as cold and heat preservation, heating system, and special concrete formula to ensure that the mixing station can operate safely and efficiently in winter.
