HZS75 concrete mixing plant

HZS75 concrete mixing plant is a kind of equipment widely used to produce concrete in construction projects.

I. Composition of equipment

HZS75 concrete mixing plant is mainly composed of the following parts:

1. Mixer：
   • JS1500 type double horizontal shaft forced mixer is usually used, which is characterized by good mixing quality and high efficiency. The nominal capacity of the mixer is 1500L, which is capable of handling various ratios of concrete, including dry-hard, semi-dry-hard, plastic, etc.
2. Dosage system：
   • The batching machine is responsible for mixing all kinds of raw materials according to the set proportion to ensure the stable quality of concrete. Most of the batching machine models are PLD series, such as PLD1600 or PLD2400. The number of compartments of the batching machine is usually 3-4 compartments, and the batching capacity is 2400L, which is capable of storing and accurately weighing a variety of aggregates.
3. Conveying system：
   • It includes aggregate conveying device, powder conveying device, etc., which is responsible for conveying the raw materials from the storage warehouse to the mixer. The conveying system adopts equipment such as belt conveyor or screw conveyor to ensure accurate and timely transportation of raw materials.
4. Metering system：
   • It is used to accurately weigh a variety of raw materials, including aggregates, cement, powder, water and additives. The weighing system adopts high-precision electronic scales to ensure the accuracy of concrete proportioning. As for weighing accuracy, the weighing accuracy of sand and gravel aggregate is generally ±2%, while the weighing accuracy of cement, powder, water and additives is ±1%.
5. Control system：
   • It adopts microcomputer control for fully automatic operation to realize the automation and intelligence of the production process. The control system usually adopts PLC automatic control system, which is characterized by easy operation and high reliability. Through the control system, it can realize precise control of each link such as mixing, batching, conveying, etc., and improve the production efficiency and quality.
6. Material storage systems：
   • These include cement silos, powder silos, aggregate silos, etc., which are used to store various raw materials required for the production of concrete. These warehouses usually have a large capacity to meet the needs of long time continuous production. For example, the cement silo mostly uses three 100-ton storage tanks.
7. Attachments：
   • It includes control room, power distribution room and office, which are used to manage and maintain the daily operation of the mixing plant. The control room is equipped with control consoles and monitoring equipment to monitor the production process and equipment status in real time. The power distribution room is responsible for providing power supply to the whole plant.

II. Technical parameters

The main technical parameters of HZS75 concrete mixing plant include:

• theoretical productivity: 75 m³/h, meaning that under ideal conditions the mixing plant can produce 75 cubic meters of concrete in one hour.
• Power of mixing machine: Generally 60KW, providing strong power support for the mixing process.
• Discharge height: Usually around 3.8 meters, but the exact height can be customized according to customer needs.
• Total installed power: Approximately 179.5KW, including the power of each part of the mixer, batcher, conveyor, etc.
• Overall dimensionsLength x Width x Height: approx. 24120 x 9940 x 17190mm

III. Characteristics of the equipment

1. High degree of automation: Adopting microcomputer control full automation operation to realize the automation and intelligence of the production process and reduce the difficulty of manual operation and labor intensity.
2. Accurate measurement: High-precision electronic scales are used for measurement to ensure the accuracy of concrete proportioning and improve the quality of concrete.
3. High production efficiency: Theoretical productivity is up to 75m³/h, which can meet the needs of large-scale construction.
4. structurally soundThe overall structure is reasonable, beautiful and generous, and it is easy to install and dismantle quickly and convenient to be transported. It has a variety of layout forms, which can adapt to the requirements of different sites.
5. Good environmental performance: All the powdery materials in the feeding, batching, measuring, adding to mixing and discharging are carried out in closed condition, the use of high-quality dust collector in the mixing main building, and the packaging closure of the mixing main building and the belt conveyor, which greatly reduces the pollution of the environment caused by the dust and the noise.
6. Good maintenance performanceEach repair and maintenance part is equipped with a platform or ladder, and the mainframe is cleaned with a high-pressure pump cleaning device, which is convenient for the daily maintenance and upkeep of the equipment.

IV. Areas of application

HZS75 concrete mixing plant is widely used in the construction of various industrial and civil building projects, roads, bridges and other projects. Specifically, it is suitable for medium-sized as well as small-sized and above construction projects, hydropower, highway, harbor, wharf, bridge and other engineering construction as well as precast plant and commercial concrete company.

In summary, HZS75 concrete mixing plant plays an important role in construction projects with its high efficiency, stability, high automation and accurate measurement.
