Mixing unit – This is the most critical part and heart of the concrete batch mixing plant. The job of the mixer is to receive all the ingredients and mix them thoroughly for a fixed time. Then it will discharge the contents into a transit mixer or a concrete pump.
From this we can see that the difference between the stabilized soil mixing station and the concrete mixing station is: 1. Since the proportion of cement required for stable soil production is small, the number of cement tanks in the stabilized soil mixing plant equipment is very small, and often only one or two are needed. 2.
The mixing time or period should be measured from time all the cementing materials and aggregates are in mixer drum till taking out the concrete. Mixing time depends on the type and size of mixer, on the speed of rotation, and on the quality of blending of ingredients during charging of the mixer.
The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of 0.55, which translates to 55 pounds of water for every 100 pounds of cement. When mixing concrete, it's necessary to ensure that there is an adequate amount of aggregate.
Once mix design is established, the first task is to batch materials.Batching is the process of measuring and combining required ingredients of concrete by either by weight or by volume as per the mix design and introducing them into a mixture to produce a uniform quality of concrete.

With this type of mixer, the shaft and blades (or paddles) rotate through the concrete mix, and the container or drum remains fixed. This was the second innovation of mixers during the early 1900s. While these mixers have double the mixing intensity of a drum mixer, they may require the same amount of time to thoroughly produce a mix.
The dry batching concrete batching plant is not equipped with a mixer system, and all aggregates are mixed by a concrete mixer truck (tank truck). The working process is: aggregates such as sand, gravel and cement are weighed by electronic scale or manual scale, and then the weighed aggregates are discharged into the mixer.
Concrete that is partially mixed in a plant mixer and then discharged into the drum of the truck mixer for completion of the mixing is called shrink mixed concrete. Central mixing plants that include a stationary, plant-mounted mixer are often actually used to shrink mix, or partially mix the concrete.
Whether you hand mix concrete in a plastic tub, homemade mixing tub or wheelbarrow, the technique is the same to find the right concrete mix ratio. However, it's easier to move and dump concrete that's mixed in a wheelbarrow. For larger jobs, you could rent a mixer ( per day), but it may be more economical to simply order ready-mix concrete.
Transit mix concrete plants rely on each individual truck driver for quality control. Cement balling problems will occur when relying on transit mixers to do the mixing. The aggressive mixing action of a central mixer eliminates cement balling. Transit Mixers are designed for multiple purposes. Auger the mix into the mixing truck drum. Mix the ...
The concrete that mix and bathed in a central mixing plant is called as ready-mix concrete. The mixed concrete is brought to the site with the help of a truck-mounted transit mixer. This once reached in the site can be used directly without any further treatment.
