I. Basic parameters

• Equipment model：HZS270
• theoretical productivity: 270m3/h, which means that under ideal conditions, the mixing station can produce 270 cubic meters of concrete per hour.The HZS270 mixing plants of different brands and manufacturers may differ slightly in their specific production capacity, but they can all meet the needs of large-scale engineering projects.
• Mixing host model: JS4500 type double horizontal shaft forced mixer is usually used, which is the core component of the mixing station and is responsible for the mixing of concrete.The power and performance of the mixing host directly affect the production capacity and concrete quality of the mixing station.
• installed capacity: The installed capacity of different brands of HZS270 mixing stations may vary, but it is generally between 300kW and 400kW.This includes the sum of the power of the mixing host, batching system, conveying system, control system and other parts.
• Mixing motor powerMixing host power: Generally 2×75kW, which is the main power source of the mixing host to ensure the smooth progress of the mixing process.
• Batching capacity: The batching system is usually equipped with a high-performance batching machine and a precise weighing system, which can accurately weigh various raw materials according to the ratio requirements.Common batching machine models are PLD7200 and so on.
• Discharge height: Generally 4m to 4.2m, but the specific height can be adjusted according to customer needs.

II. Composition of equipment

HZS270 concrete mixing station is mainly composed of mixing host, batching system, conveying system, control system, dust removal system and other parts：

1. Mixer: JS4500 type double horizontal shaft forced mixer is used, which has the characteristics of good mixing quality, short mixing time, and long life of wearing parts.The mixing host is equipped with a wear-resistant liner and a high-strength mixing arm to ensure the uniformity and stability of the concrete.
2. Dosage system: Including aggregate silos, powder silos, water and additive weighing systems, etc.The aggregate silo and the powder silo are respectively used to store aggregates and powders (such as cement, fly ash, etc.), and the weighing system is responsible for accurately weighing various raw materials in accordance with the ratio requirements.
3. Conveying system: Including belt conveyors, screw conveyors, etc.Belt conveyors are used to transport aggregates from the aggregate silo to the batching machine, while screw conveyors are used to transport powder from the powder silo to the mixing host.The conveying system adopts a sealing device to reduce dust pollution.
4. Control system: Adopt advanced PLC automatic control system and industrial computer synchronous control system to realize automatic operation and remote monitoring of equipment.The control system has functions such as ratio storage, automatic gap compensation, data cloud storage, and printing to ensure the accuracy and stability of concrete production.
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 adopts a closed structure to ensure that dust is effectively collected and treated.

III. Product characteristics

1. Efficient production: The hourly production capacity reaches 270 cubic meters to meet the needs of large-scale engineering projects.
2. Stable and reliable: The equipment configuration performance is good, the degree of automation is high, and the accuracy and stability of concrete production are guaranteed.The control system has stable performance and adapts to various production environments.
3. Energy saving and environmental protection: Adopt a closed sand and gravel weighing and conveying system and a negative pressure bag pulse dust removal system to reduce noise and dust pollution to the environment.At the same time, the equipment pays attention to energy saving and consumption reduction in the design and manufacturing process to reduce energy consumption.
4. Convenient operation: Advanced industrial computer synchronous control system and professional control software make the operation simple and convenient.The modular design makes installation, maintenance and overhaul convenient.
5. Strong adaptability: Meet different construction needs, including the batching requirements of different raw materials and concrete types.At the same time, the equipment can be customized design and production according to customer needs.

IV. Areas of application

HZS270 concrete mixing station is widely used in roads, bridges, tunnels, water conservancy and electric power, construction and other fields.In these fields, the strength, uniformity, durability and other aspects of concrete are extremely demanding, and the high performance, high stability and high efficiency of the HZS270 concrete mixing station can just meet these requirements.

V. Maintenance and upkeep

In order to ensure the long-term stable operation of the HZS270 concrete mixing plant, regular maintenance and maintenance are required.It mainly includes the following aspects：

1. Regularly check the wear of the blades and liners of the mixing host, and replace the worn parts in time.
2. Check the lubricating oil level and oil quality of the mixing host, and replace the lubricating oil regularly.
3. Check the accuracy of the sensors and scales of the batching system to ensure accurate weighing.
4. Inspect conveyor system belts and pulleys for wear and tear, replace worn parts and adjust belt tension in a timely manner.
5. Clean the filters and collectors of the dust removal system to ensure that the dust removal effect is good.
6. Conduct a comprehensive inspection and maintenance of the control system to ensure the normal operation of each component.

Through the implementation of the above-mentioned maintenance and maintenance measures, the long-term stable operation and efficient production of the HZS270 concrete mixing plant can be ensured.
