A volumetric mixer truck is a specialized vehicle used to transport and mix concrete at a construction site. It offers the flexibility of mixing fresh concrete on-site while adjusting the components' quantities. There are many types of concrete mixer trucks and mixer trucks.
Self-Loading Mobile Mixers:
An innovative concept of a mobile mixer truck, self-loading mobile mixers have the ability to load raw materials on their own. They are typically equipped with a high-tech control system to ensure precise mixing ratios and monitor progress. One notable aspect of self-loading mobile mixers is their ability to reverse the mixing process. This is particularly advantageous when it comes to cleaning and maintenance of the equipment.
Semi-trailer Mixers
Semi-trailer mixer trucks are open-chassis trailers towed by a front truck. They are similar to the standard mixer truck in terms of features and use. The trailers detach from the taxi truck and can themselves be transported by a freight truck. This makes semi-trailer mixers a preferred choice as an easy-to-use mixer cement truck for the operator.
Volumetric Mixers:
Volumetric mixer trucks are distinguished by on-demand mixing of concrete while traveling. This ability to offer just-in-time concrete aids in reducing waste and ensuring that the concrete is fresh and of high quality. Furthermore, volumetric mixer trucks excel in precision and versatility. Thanks to sophisticated measurement and control systems, drivers can adjust the mix ratios and quantities of different ingredients, such as cement, water, sand, and aggregates, to meet the specific requirements of each project.
One of the most significant advantages of volumetric mixer trucks is their adaptability to different types of concrete mixtures, such as normal-strength, high-strength, self-leveling, swivel seals, and more. In addition to butter, the trucks are equipped with multiple bins that can hold different types of aggregates, such as gravel, sand, and other materials, ensuring a consistent and uniform concrete mix.
Truck power
The power of the volumetric mixer truck may be in kilowatts (KW) or horsepower (HP), and it determines the engine's strength and capacity.
Payload capacity
This describes the maximum weight the truck can handle, which is often in tons. For volumetric mixer trucks, it indicates the maximum weight of the concrete it can transport.
Cement silo capacity
This is the maximum storage capacity of the truck's cement silo, usually measured in cubic feet or tons. It shows how much cement the truck can carry for mixing concrete on-site.
The number of silos
This describes the quantity of cement storage compartments in the truck. Different trucks may have various numbers of silos, impacting the diversity and volume of materials that can be transported.
Mixing drum volume
This refers to the maximum volume that the truck's mixing drum can hold, which is measured in cubic feet or liters. It indicates the truck's concrete mixing and transportation capacity.
Drum material and surface treatment
Generally made of high-strength steel, the material and its surface treatment (e.g., galvanization, anti-corrosion paint) possess various properties to ensure the drum's durability and anti-corrosiveness.
Mixing speed
This refers to the truck's mixing operation speed, expressed in revolutions per minute (RPM). Higher mixing speeds can ensure better mixing quality and efficiency.
Operation interface
This includes details about the truck's control system, such as whether the truck employs automatic or digital controls, as well as the kinds of functions and parameters that can be adjusted.
Regular cleaning
The drum of the mixer truck is made of special alloy steel plates with higher strength and better durability. After each transportation task, promptly clean the residual concrete in the drum. During the cleaning process, use water and additives to prevent corrosion and prolong the truck's lifespan. Regularly clean and maintain the mixer truck to keep it sanitary and reduce the risk of disease transmission.
Lubrication and maintenance
The mixing drum truck is equipped with many moving parts, such as bearings, chains, and more, which require periodic lubrication to ensure smooth operation and reduce wear and tear. Hence, checking the mixer truck parts and repair or replace the damaged parts and components from time to time is crucial.
Additionally, the tire pressure and condition of the truck should be checked regularly, and the tire should be rotated and balanced to ensure stable and smooth driving and avoid accelerated wear of the tires.
Efforts should be made to maintain a steady speed and smooth driving when using a volumetric mixer truck to avoid violent braking and rapid acceleration and to protect the truck better.
Volumetric concrete mixer trucks have vast industry applications in construction. Here are some key usage scenarios:
Small-to-Medium-Sized Construction Projects
Mixers are ideal for buildings, pavements, driveways, and sidewalks. They deliver exact amounts of concrete for smaller projects where on-site mixing will suffice.
Remote Locations
Because they mix concrete on-site, volumetric trucks can supply concrete in remote areas far from batch plants. This eliminates long travel times.
Changing Concrete Needs
Volumetric mixers allow contractors to adapt the quantity and concrete mix. They can modify the mix design on-site for different project phases.
Cost-Effective Solutions
Mixers minimize material waste since clients only pay for the concrete used. This makes them cheaper for smaller projects than hiring a static mixer.
Fast-Paced Construction
The ability to mix and pour concrete on-site rapidly makes volumetric trucks useful when speed is essential, such as in large volume construction, refurbs, or infrastructural works.
Overhead Access
Volumetric trucks can pour concrete from their chutes or pumps. This feature works well for sites with limited access, such as when constructing elevated structures like slabs and beams.
Environmental Sensitivity
The low level of concrete waste produced by volumetric trucks is environmentally friendly. Contractors can recycle surplus concrete on other projects.
High-Quality Concrete
Volumetric mixers can incorporate additional features, such as admixtures for better mix design, giving customers high-performance concrete tailored to their needs.
When choosing a volumetric concrete mixer truck for sale, buyers should examine several features to ensure that they get a machine that will meet their needs. First, buyers should identify the capacity they need in a concrete mixer truck. It's important to get a machine that has a capacity that is equal to the highest demand of concrete that is usually needed per day. The capacity of trucks usually ranges from four to twenty-five cubic meters.
Another essential factor to consider is the type of mixing required. Buyers should know that volumetric mixers will usually provide on-site mixing. However, they should consider the kind of mix that is needed in their line of work. Buyers should also consider the machine's ease of use and whether their operators will need extensive training to operate the machine. In most cases, mixers with straightforward control systems and intuitive interfaces minimize the need for training.
In addition to the items listed above, buyers should check the truck’s accuracy and calibration features. The mixer they choose should have reliable systems to ensure that concrete is not over-used or under-used when making orders. More importantly, buyers should get trucks that have been manufactured with safety features such as emergency braking systems, anti-slip surfaces, and load monitoring systems to help prevent accidents that can arise due to overloading or underloading.
When selecting the mixer, buyers should consider additional features and options such as automatic calibration, telematics, and batch tracking. Such features can make the process of concrete mixing and delivery even more efficient and seamless. Buyers should also look at the maintenance accessibility of the mixer they intend to purchase. The truck needs to have a well-illustrated manual and accessible components to allow for regular maintenance and servicing.
Finally, buyers should consider the fuel efficiency of the concrete mixer truck in order to manage operational costs. They can do this by choosing energy-efficient models with low carbon outputs and high fuel economy.
