1. Medium-sized concrete mixers
Working Principle
Medium-sized concrete mixers usually adopts forced mixing principle, equipped with double-shaft or single-shaft mixing paddles. During operation, the mixing paddles rotate rapidly in the mixing cylinder, exerting strong shearing force on the mixed materials, thus providing effective mixing.
Applications
Suitable for small and medium-sized construction projects
Highway, bridge and other infrastructure projects
Suitable for concrete production of small prefabricated components
Advantages and disadvantages
Advantages: homogeneous mixing, fast discharging, suitable for a variety of different ratios of concrete; relatively simple operation.
Disadvantages: Larger machine, relatively high cost, higher requirements for the site.
Precautions
Check the mixing paddle and motor regularly to prevent wear and tear.
Make sure the mixer is in a balanced state before operation to avoid tilting.
Clean it in time after each use to prevent concrete residue from affecting the next use.
2. Diesel Concrete Mixer
Working Principle
Diesel concrete mixer takes diesel engine as the power source, and is usually of self-falling or forced structure. The diesel engine drives the mixing device to complete the concrete mixing process.
Application
Suitable for remote areas and construction sites without power supply.
Mostly used in infrastructure construction and ground laying construction
Advantages and disadvantages
Advantages: strong mobility, suitable for use in areas lacking power supply; lower operating costs.
Disadvantages: high noise level, exhaust emission affects the environment; complicated maintenance and upkeep.
Precautions
Pay attention to the addition of fuel and the maintenance of the machine to ensure that the engine works normally.
Pay attention to prevent leakage during operation to protect the environment.
Regularly check and replace filters and other wearing parts.
3. Tilting Drum Concrete Mixer
Working Principle
Tilting Drum Concrete Mixer puts raw materials into the mixing drum through the tilting drum. With the rotation of the drum, the raw materials are tumbled in the drum and mixed with each other. The gravity of this type of mixer is more obvious, so it is generally used for small and medium-sized concrete mixing.
Applications
Small construction and renovation projects
Construction of asphalt concrete, foundations and base layers
Advantages and disadvantages
Advantages: simple structure, easy to use, suitable for small-scale construction; lower equipment cost.
Disadvantages: the mixing uniformity may be slightly inferior to that of forced mixers; the operating experience of the operator is required to be higher.
Precautions
Before use, the operation status of drum and motor should be checked to avoid malfunction.
During operation, materials should be prevented from overflowing and causing environmental pollution.
Regular cleaning and maintenance should be carried out to prolong the service life of the equipment.
4. Automatic Concrete Mixer
Working Principle
The automatic concrete mixer manages the mixing process fully automatically through the computer control system. Users can input the formula and the machine realizes a series of processes such as automatic feeding, mixing and discharging according to the set parameters.
Application
Large-scale concrete mixing plant
High-standard concrete production and precast component manufacturing
Advantages and disadvantages
Advantages: high precision, can ensure the quality and proportion of concrete; reduce manual intervention, improve work efficiency.
Disadvantages: Higher investment cost of equipment, maintenance and troubleshooting require professional technical support.
Precautions
Regularly carry out inspection and update of software and hardware to maintain the stability of the system.
Familiarize yourself with the automation system and safety protection measures before operation.
Dispose of concrete residue in time to keep the equipment clean.
5. Electric Concrete Mixer
Working Principle
Electric concrete mixer is powered by electric motor, the transmission system transfers the power to the mixing device, and the mixing paddle carries out mixing work in the mixing cylinder. This kind of equipment is easy to operate and suitable for various sites.
Applications
Small and medium-sized construction projects
Residential renovation and home DIY projects
Advantages and disadvantages
Advantages: easy to operate, relatively low noise, no exhaust fumes; suitable for a wide range of concrete mixing ratios.
Disadvantages: Power supply limits the place of use and requires a good power supply; the capacity of delivered concrete is relatively small.
Precautions
Pay attention to electrical safety when operating in humid environment to avoid short circuit.
Pay attention to the ventilation and heat dissipation of the equipment to prevent overheating.
Check the motor and its connecting wires regularly to ensure reliability and safety.
Summarize
Different types of concrete mixers are suitable for different construction needs and environments, some emphasize mobility and flexibility, while others pay attention to output and automation control. Choosing the right mixer can effectively improve work efficiency and concrete quality. In the process of use, it is necessary to comply with the relevant operating procedures, and timely maintenance to ensure the safety and stable operation of the equipment.
