What Should be Paid Attention to When Installing Concrete Mixing Plant?

When installing a belt - type concrete mixing plant, the following precautions should be noted and corresponding mistakes should be avoided:

Pre - installation Preparation

- Site and Foundation

Site Planning: It is necessary to fully consider the layout of each component of the mixing plant, including the running direction of the belt conveyor, the positions of the cement silo, mixer, etc. Ensure that the distance between the equipment is reasonable, which is convenient for raw material transportation and finished product output, and avoid potential operation inconvenience or safety hazards caused by insufficient space in the later stage.

Foundation Construction: The foundation must be firm and level. Construction should be carried out in accordance with the design requirements to ensure that the bearing capacity of the foundation meets the equipment requirements. Avoid foundation settlement or uneven settlement, which may lead to equipment tilting, deformation or even damage. The dimensions, flatness, and positions of embedded parts of the foundation should be strictly inspected and verified.

- Technology and Personnel

Review of Technical Documents: Carefully review the installation drawings, operation manuals and other technical documents of the equipment to understand the structure, installation requirements and technical parameters of the equipment, and be clear about the key steps and precautions in the installation process, so as to avoid installation errors due to unfamiliarity with technical requirements. -

Personnel Training and Qualifications: The installers should possess professional skills and experience, and be familiar with the installation process and safety regulations of the concrete mixing plant. Before installation, conduct safety and technical disclosure and training for all installers to ensure that they understand the risks and precautions of the installation work.

Equipment Installation Process

- Installation of Belt Conveyor

Installation of the Frame: Ensure the straightness of the center line of the frame, and keep both sides of the frame horizontal to avoid belt deviation. Each idler and drum should rotate flexibly, and the installation position should be accurate. The cleaner should be in uniform contact with the belt and be able to rotate freely.

Installation of the Belt: The tension of the belt should be adjusted appropriately. Excessive tension will increase the wear of the belt and equipment, while too loose tension may cause the belt to slip. Pay attention to the direction of the belt and the connection quality of the joint during installation to ensure the smooth operation of the belt.

- Installation of Cement Silo

Verticality Control: When lifting the cement silo, ensure its overall verticality. Check the verticality at any time during the installation process, and the deviation should meet the specified requirements. Avoid the inclination of the cement silo, which affects the safety of material storage and transportation.

Fixing of Legs: The bottom of the legs must be welded firmly to the foundation embedded parts, and the welding quality should meet the requirements to prevent the legs from deforming or loosening.

Installation of Concrete Mixer

Level Adjustment: The chassis of the mixer should be raised and adjusted to a horizontal state, so that the center line of each leg coincides with the center line of the root, ensuring the stable operation of the mixer and avoiding uneven mixing or excessive equipment vibration.

Inspection of Connection Parts: Check the connection parts of the mixer, such as bolts, pins, etc., to ensure they are firmly connected and have anti - loosening measures to avoid loosening during operation, which may lead to equipment failure.

Installation of Electrical System

Grounding and Zero - connection Protection: Do a good job in the grounding and zero - connection protection of electrical equipment. The grounding resistance should meet the requirements. The protective wires of motor cables, the outer shells of electrical boxes, etc. should all be electrically connected to the main grounding bolts and main grounding electrodes, and the protective wires shall not be connected in series to prevent electric shock accidents.

Circuit Arrangement and Labeling: The arrangement of electrical circuits should be neat and standardized. Avoid circuit crossing, extrusion or exposure. Label each circuit well to facilitate later maintenance and repair.

Inspection and Commissioning after Installation

- Overall Inspection

Appearance Inspection: Check whether the appearance of the equipment is damaged or deformed, whether the connections of all components are firm, and whether the sealed parts are well - sealed. Deal with any problems in time.

Lubrication and Cleaning: Check and replenish lubricating oil at each lubrication point of the equipment, and clean the debris and dust on the surface of the equipment to ensure the equipment is clean.

- Commissioning and Operation

No - load Commissioning: Start the equipment in no - load condition, and check the operation of each component, such as whether the running speed and direction of the belt conveyor are normal, whether the mixing blades of the mixer rotate smoothly, and whether the control of the electrical system is sensitive and reliable.

Load Commissioning: After the no - load commissioning is qualified, carry out load commissioning. Gradually increase the input of materials, check the operation of the equipment under different loads, and at the same time check the accuracy of the metering system. Adjust it in time if there is any deviation.
