HZ Stationary concrete plant

Concrete batching plant is a combined device used to centrally mix concrete, also known as ready mix concrete center. The concrete batching plant is mainly composed of five major systems including the main mixer, batching system, conveying system, storage system and control system, and other ancillary facilities. Due to its high degree of mechanization and automation, the productivity is also high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, electric power, bridge and other projects with large concrete volume, long period and concentrated sites. According to customer requirements, TRISUN supplies wet (with mixer) or dry (without mixer) stationary batching plant equipped with twin-shaft mixers or planetary mixers from 25 cubic meters to 180 cubic meters per hour. Among them, the quantity and capacity of aggregate hoppers, additive tanks and cement silos can be customized.

FAQ

Q: What are the operating procedures and precautions for concrete batching plants?

A: 1) It needs to be installed firmly.

2) It should be checked whether it has been commissioned before formal work.

3) During the production process, supporting equipment cannot be overloaded.

4) During operation, if there is a sudden power outage or failure, the materials in the mixing drum should be cleaned manually and then inspected or repaired.

5) If the operator needs to enter the mixer for cleaning or maintenance, the switching power supply should be strictly controlled.

Q: Why does a concrete plant use a forced mixer instead of a gravity mixer?

A: 1) Mixing principles. When the forced concrete mixer is working, the drum remains stationary, the mixing shaft rotates, and the mixing arm drives the mixing blade to continuously forcefully mix the materials in the drum; When the gravity concrete mixer is working, the mixing drum rotates. The mixing blades installed in the mixing drum make the materials continuously rise and lift. After reaching a high place, the materials fall downwards by their own gravity and produce axial movement.

2) Mixing cycle. Comparing these two mixers, the mixing effect of the forced mixer is more intense. It generally only takes 30-60 seconds to mix the materials into homogeneous concrete. For special concrete, the mixing cycle may be longer; However, the mixing cycle of a gravity mixer needs to be doubled or even longer.

3) Energy consumption.

Under the same mixing capacity, the driving power of the forced mixer is greater than that of the gravity mixer, and the corresponding total installed power of the mixer and power distribution facilities need to be increased. However, due to its relatively short mixing cycle, the unit energy consumption of producing concrete has not increased much.

Q: What are the safety production precautions for concrete plants?

A: 1) Before starting work, all fasteners and wire ropes must be inspected and tightened in accordance with the operation manual, and lubricating oil must be added to the parts that need lubrication.

2) When the mixing plant is working, no one is allowed to touch the transmission device, or open the mixer cover and other protective facilities.

3) When the mixing plant is working, no one is allowed to stand in the loading and unloading areas.

4) When the mixer is working, it is strictly prohibited to stop it in the middle. In case of power outage, the discharge door should be opened immediately to drain the concrete in the main mixer to prevent condensation.

5) The reliability of switches, buttons, indicator lights and other electrical equipment should be checked regularly according to the requirements of the operation manual.

6) All electrical pipelines should be properly protected to prevent them from being crushed or bruised during work.

7) It is strictly prohibited to change the working mode while the system is running. If you need to change it, please follow the operating instructions.

8) When the mixing plant is inspected, especially when inspecting the main mixer, the main power supply must be disconnected and a dedicated person must be assigned to take care of it.

9) Both the power system and the control equipment have high requirements for power supply, and the voltage fluctuation of the working power supply should be controlled within the range of ±5%.

10) If an unexpected situation occurs, press the emergency stop button immediately, disconnect the main power supply, and then restart after confirming that the fault has been eliminated.
