Mobile concrete mixers, or mobile concrete distributors, sometimes referred to as mobile concrete mixers, are a solution for on-demand concrete production. The mobile concrete mixer is a batching equipment installed on the chassis-usually a truck or trailer, which transfers unmixed materials (sand, cement, coarse aggregate, water and any other materials or more chemicals required for special applications). 名媛直播) are transported to the work site and mixed continuously or intermittently as needed to obtain fresh maximum strength concrete.
As long as the material is reloaded at the work site, any amount of concrete can be produced every day, from one yard to 400 yards or more, for continuous pouring. The volume ratio is based on volume rather than weight. Therefore, through a simple calibration process, concrete that meets or exceeds ASTM C685 and AASHTO M-241 standards and DOT requirements can be produced. You can get the exact quantity you need every time.
The mixing of materials is a continuous process, mixing aggregates, sand, cement, water and additives to get an accurate mixture every time. Operators can stop mixing and conveying and start again at any time, which allows production to balance the needs of sorting and placement personnel or other work requirements.
The design of the mixture can be changed or changed without moving the machine, and the operator can adjust it at any time according to the needs of the work site. When the work is completed, only the mixer area is cleaned. The cleaning process is very simple.
The mobile concrete mixer has a separate silo.
The mobile mixer loads sand, cement, coarse aggregates and other materials in the sub-bins installed on the equipment. All the bins are loaded from the top, and the cement bin has a watertight cover. The water on the stirring device is also carried by a water tank, and the size of the water tank may vary depending on the model.
Sand and stones are divided into side by side open-top silo, sand occupies 45% of the silo volume, and the stone side occupies 55%. Aggregates can be transported individually or mixed according to the needs of the designed mixture. The versatility of the mobile mixer makes the concrete mixture almost unlimited.
Cement is transported in a watertight silo. Automatic vibrators and mechanical devices ensure accurate cement ratio and constant flow of cement to the feeder. Water is transported in the water tank and pumped into the mixer; the water flow control and flow meter accurately monitor the flow, and automatically stop and start whenever the conveyor belt stops or starts.
For other concrete output requirements or special types of work, liquid admixtures such as accelerators, retarders, air-entraining agents, modified latex, etc. can be carried out in a separate system, and ingredients can be introduced as needed through flow control and flow meters.
What proportioning system does the mobile concrete mixer use?
The core of the volumetric mobile mixer is to measure (or proportion) by volume instead of weight, and the accuracy of the final product is better than +/-1%. The materials are stored in separate bins and proportioned according to the mixing design; this enables the operator to accurately mix the required materials on site, eliminating excesses and shortages. The ratio allows the operator to control the mix design and the amount of mix.
Stir
One difference of the mobile concrete mixer is that the materials are mixed on site, so the mixture is fresh, has not started to solidify, and has not been rejected because of being late to the construction site. The materials are thoroughly mixed through a volumetric process to produce high-quality concrete in precise quantities.
The concrete is fresh every time, and its strength is the greatest. Check out this white paper to compare the output of volumetric concrete mixers and traditional ready-mixed concrete. The concrete produced by the mobile concrete mixer complies with ASTM 685 and AASHTO M-241 standards and the standards required by DOT.
Application of mobile concrete mixer
Mobile concrete mixers can be used for different projects and solutions to many problems. The most important aspect that a mobile concrete mixer can bring is flexibility, which can keep fresh concrete on site whenever needed. These are some of the most common applications and uses of mobile concrete mixers:
Ordinary concrete, including repairs
Flow filling
Rapid-setting concrete
Permeable concrete
Pave concrete
Municipal applications
Dry and wet shotcrete
Roller Compacted Concrete (RCC)
Self-compacting concrete (SCC)
When and where need to move the concrete mixer
this is very simple. The mobile concrete mixer allows you to choose to "own" your personal concrete batching plant. Compared with traditional drum mixing, this solution can sometimes be the best cost-effective solution and time-saving equipment. If your concrete work is only a few cubic meters per week or day, then this may be the time when you need to move the concrete mixer. The solution does not need to worry about moving parts, equipment, conveyor equipment, front-end loaders and certain other equipment, but puts everything in a truck. Sometimes, you don’t even have to rent the equipment, you can even rent it out and deliver it to your work site, and you can control the specific delivery and timing.
Benefits of using mobile concrete mixer
In addition to the size and space required to maintain a mobile mixer, the portable device can also beat other traditional drum mixers because it can reach many places and the concrete mix is easy to change. These are some of the benefits of using a mobile concrete mixer:
Benefits for your business
Increase profits by paying less concrete costs and better control your schedule and staff time.
To expand the types of concrete applications, you can provide a mixer unit as part of your business, or do multiple jobs without having to go back to the factory between jobs.
Benefits for your customers
By freshly mixing the required quantities on site, complaints about shortages and excesses are eliminated.
Use the mixer to flexibly handle short loads, emergencies or weekend work, and can be used for any scale of work in a short time.
The cost of mobile concrete mixer
Mobile concrete mixers can be purchased or rented. Certain volumetric agitators, depending on the capacity and function, start at $30,000, and the price will increase according to the capacity, pumping speed, and added features of the equipment. In addition, compared with traditional batch processing plants, this equipment will save more costs. If we compare the manpower required by a traditional factory, assuming that there is 1 driver, 1 QA/QC and 1 factory dispatcher, the mobile concrete mixer only needs to be driven and operated by 1 employee on the list, which is more than necessary 3 workers are cheaper.
